List of all members.

Public Member Functions
	EPSRenderRegion (DocRect ClipRect, Matrix ConvertMatrix, FIXED16 ViewScale)
	Constructor for an EPSOutputFilter object. The object should be initialised before use.
BOOL	Init ()
	Initialise an EPSOutputFilter object.
BOOL	AttachDevice (View *ViewToAttach, CNativeDC *DCToAttach, Spread *SpreadToAttach, bool fOwned=false)
	Attach the EPS render region to a device context and a spread to export.
BOOL	InitDevice ()
	Initialise the device specific mechanisms for this render region.
virtual BOOL	RenderChar (WCHAR ch, Matrix *pMatrix)
virtual BOOL	SaveAttribute (UINT32 Index, AttributeValue *pAttr, BOOL Temp)
	Saves the current attribute on the attribute context stack, and installs the given attribute as the new attribute. If the attribute object is temporary, then it is deleted when the attribute is popped off the stack. See RenderRegion::RestoreAttribute.
virtual BOOL	CloseDown ()
	Tells the EPS render region that all rendering is finished and the region is about to be shut down, so it should output any trailer etc that is required.
virtual void	DrawPathToOutputDevice (Path *PathToRender, PathShape shapePath)
	Output all the commands required to render this path to the EPS file.
void	ExportPath (Path *DrawPath, BOOL DataOnly, BOOL PureDataOnly=FALSE)
	Output all the commands required to render this path to the EPS file. If this is a compound path, the stroke/fill operators will always be output, regardless of the value of the DataOnly parameter.
virtual void	GetValidPathAttributes ()
	Ensure the EPS context has the correct attributes for drawing paths. This required because when the path attributes change, we don't output the EPS commands to reflect this straight away - we set a flag to indicate that the attributes have changed, and then when this function is called, it notices that the attributes have changed, and outputs the EPS commands to select these attributes. This avoids redundant and copious attribute code in our EPS files. (The flags used are ValidPen and FillFlags.ValidGeometry).
virtual void	GetValidTextAttributes ()
	Text equivalent of GetValidPathAttributes().
virtual void	GetRenderRegionCaps (RRCaps *pCaps)
	This function allows render regions to admit to what they can and can not render. This allows other areas of the program to come in and help render regions out in some situations, if they are unable to render everything. eg. an OSRenderRegion can not render transparancy.
virtual BOOL	WantsGrids ()
	This function is designed to help with the rendering of grids, as they are not always wanted (eg xara eps). EPS classes generally do not want to render grids. The ones that do (NativeEPS) should replace this with a version that returns TRUE.
virtual BOOL	WriteNewLine (void)
	Outputs a new line tag to the file.
virtual void	SetClipRegion (ClipRegionAttribute *pClipAttr, BOOL Temp)
	Shrink the RR's clipping region to the region defined by pClipAttr. We do this by: 1. Recording a save-state command. 2. Exporting a description of the clipping path in pClipAttr. 3. Recording a 'clip-to-last-path' command. 4. Recording a 'start-new-path' command, as we don't want our clip-path to get stroked or rendered in any way.
virtual void	RestoreClipRegion (ClipRegionAttribute *pClipAttr, BOOL Temp)
	Restore the RR's clipping region. We do this by recording a restore-state command.
Protected Member Functions
virtual void	OutputFontName (void)
	Output an Illustrator format fontname and pointsize token. The format is /_fontname[-Bold|-Italic|-BoldItalic] pointsize Tf. EncodeFontName will generate this format from an internal fontname. DocodeFontName will return an internal format fontname and flags where nec.
INT32	GetFontStyle (void)
	Compile the current style attributes.
virtual BOOL	WriteEPSVersion (void)
	Writes the EPS version used by this particular file type.
virtual BOOL	WriteEPSBoundingBox (void)
	Writes an EPS bounding box.
virtual BOOL	WriteEPSProcessColours (void)
	Does nothing - process colours are only relevant in AI files.
virtual BOOL	WriteEPSResources (EPSFilter *pFilter, Document *pDocument)
	This is a stub function, that's over-loaded in the AIEPS render region. It's used to write out the necessary resources for an AI file.
virtual BOOL	WriteEPSProlog (EPSFilter *pFilter, Document *pDocument)
	This is a stub function, that's over-loaded in the AIEPS render region. It's used to write out the necessary Prolog script for an AI file.
virtual BOOL	WriteEPSTrailerComments (void)
	Writes the comments out at the end of an EPS file.
virtual BOOL	WriteProlog (KernelDC *)
	Output any PostScript prolog for this render region. For EPS and printing, this means output of our PostScript rendering procedures; for Native files we do nothing.
virtual BOOL	WriteSetup (KernelDC *)
	Output any PostScript setup for this render region. For EPS and printing, this means output of our PostScript code to initialise the context for rendering; for Native files we do nothing.
virtual BOOL	WriteSepTables (KernelDC *)
	Output the current set of device printer profiles as Postscript data arrays. Our Postscript prolog functions will use these arrays when creating separations. (if we are not separating, we do nothing).
virtual BOOL	WriteSepFunctions (KernelDC *)
	Output the current set of separation functions for this EPS file if any. These will usually be present in printable postscript versions of EPS render regions.
BOOL	SetLastOutputAttribute (INT32 AttrID)
	Check to see if the current attribute is the same as the last one that was output in EPS.
void	ResetOutputAttributes (void)
	Resets the attribute array so that all attributes are considered to be invalidated - i.e. the next time an attribute is needed, it will always be output, regardless of whether the last attribute output was the same as it. This is mainly used for PostScript printing when we use the OS to do text, because we cannot be sure of how the OS will leave the graphics state after doing text output, so we assume nothing, and reset all required attributes after doing text output via the OS.
virtual BOOL	WriteFileVersion (KernelDC *)
	This allows the filter to save out a comment line giving file version information. At present, in anything but Native format, it does nothing.
virtual BOOL	WriteCompressionState (KernelDC *)
	This starts the compression process. Called just after we output the document information so that this is not compressed and the galleries can access it easily. In this baseclass version we do nothing as compression would be a very bad thing.
virtual BOOL	WriteEndCompressionState (KernelDC *)
	This is called once almost everything has been output, just before we output the EOF and we fix the EPS header. In this baseclass version we do nothing as compression would be a very bad thing.
virtual BOOL	WriteGradientFills (Document *pDocument)
	This function is a stub function, which is overwritten in the AI render region.
virtual BOOL	WriteDocumentSetup (Document *pDocument, EPSFilter *pFilter)
	Browse through the tree, and if a text story is found invoke the document setup function. By only exporting the font setup when necessary, the file size produced is smaller (which makes it easier for me to interpret :) ), and it should hopefully make the filter run a bit faster too.
virtual BOOL	EndLayer (void)
	If there is an existing layer, it writes the end of layer tags, before creating a new layer record.
ColourPlate *	GetOutputColourPlate (ColourModel ColModel)
void	GetOutputColourPlate (ColourModel ColModel, ColourContext **ppContext, ColourPlate **ppPlate)
	This render region is associated with a document view. This function retrieves the colour context from this view and returns it along with a plate (if available). ColourModel is used to determin which plate to return from the context. If there is no view pContext and pPlate will be NULL. If there is no context in the view both return values will be NULL If there is a context but no plate attached to it, one can assume the current render action is not separated.
virtual void	OutputWindingRule ()
	Output winding rule token to the EPS file.
virtual void	OutputStrokeColour ()
	Output a stroke colour. This calls either OutputStrokeRGBcolour or OutputStrokeCMYKColour depending on the colour model.
virtual void	OutputLineWidth ()
	Output the standard line width token and measure for EPS.
virtual void	OutputJoinType ()
	Output the standard EPS join type.
virtual void	OutputDashPatternInit ()
	Sets up the next dash pattern for output.
virtual void	OutputDashPattern ()
	Output the current dash pattern settings. Watch for interaction with line widths, a change of line width causes the dash pattern to become invalid. To output a dash pattern correctly, use the following code.
virtual void	OutputStartCap ()
	Output the start cap setting using the usual 'J' EPS token.
virtual void	OutputMitreLimit ()
	Output the current mitre limit value using the usual 'M' EPS token.
virtual void	OutputFillColour ()
	This now delegates the output to either OutputFillRGBColour or OutputFillCMYKColour, depending on the colour model used.
virtual void	OutputStrokeRGBColour ()
	Output the current stroke colour as RGB. This function will use one of the following EPS tokens XA - if not separating and colour is unnamed XX - if not separating and colour is named G - if separating.
virtual void	OutputFillRGBColour ()
	Output the current fill colour as RGB. This function will use one of the following EPS tokens Xa - if not separating and colour is unnamed Xx - if not separating and colour is named g - if separating.
virtual void	OutputStrokeCMYKColour ()
	Output the current stroke colour. This function will use one of the following EPS tokens K - if not separating and colour is unnamed X - if not separating and colour is named G - if separating.
virtual void	OutputFillCMYKColour ()
	Output the current fill colour in CMYK mode. This function will use one of the following EPS tokens k - if not separating and colour is unnamed x - if not separating and colour is named g - if separating.
virtual void	OutputTextRenderMode ()
	Output the change in the text's Render Mode (Tr) - this happens when the text's fill or line colour changes to or from blank, see-through colour.
virtual void	OutputTextAspectRatio ()
	Output the change in the text's aspect ratio (Tx).
virtual void	OutputTextTracking ()
	Output the change in the tracking (Tt).
virtual void	OutputTextJustification ()
	Output the change in the text justification (Ta).
virtual void	OutputTextLineSpacing ()
	Output the change in the line spacing (Tl).
virtual void	OutputTextBaselineShift ()
	Output the change in Baseline shift (Ts).
virtual void	OutputTextSubSuperScript ()
	Output the change in the Sub/Super script attribute (Ts).
virtual void	WriteGradientFillInstance ()
	This function allows extra work to be done on gradient fills, when the fill and/or stroke operators are written. i.e. at the last possible moment before rendering.

[INPUTS] DataOnly - if TRUE, only output the line/curve/moveto data, and not the stroke or fill operators. if FALSE, just output path normally. NB. see Purpose PureDataOnly if TRUE, will do what the DataOnly flag does, but will really do it, instead of bottling out on compound paths! Hello, Karim here. The above is is *no longer the case* if the PureDataOnly flag is set. I *don't want any* stroke or fill operators on compound clipping paths, thankyou very much!

void EPSRenderRegion::GetOutputColourPlate (  ColourModel  ColModel, ColourContext **  pContext, ColourPlate **  pPlate )  [protected]

This render region is associated with a document view. This function retrieves the colour context from this view and returns it along with a plate (if available). ColourModel is used to determin which plate to return from the context. If there is no view pContext and pPlate will be NULL. If there is no context in the view both return values will be NULL If there is a context but no plate attached to it, one can assume the current render action is not separated. Author: Mike_Kenny (Xara Group Ltd) <camelotdev@xara.com> Date: 17/06/96 Parameters: The  colour model of the active output context to use. [INPUTS] A pointer to a pointer to a colour context (can be NULL) A pointer to a pointer to a colour plate (again can be NULL) pContext  points to the current context in the view attached to this render region [OUTPUTS] pPlate points to the plate whose model was required. Returns: - Definition at line 1646 of file saveeps.cpp. { ColourContext *pCurContext=NULL; ColourPlate *pCurPlate=NULL; // Get the render region view and find its local CMYK colour context View* pCurrView = GetRenderView(); if (pCurrView!=NULL) pCurContext = pCurrView->GetColourContext(ColModel, TRUE); // If we have a context, check for mono output. if (pCurContext!=NULL) pCurPlate = pCurContext->GetColourPlate(); // Set return vars if (pContext!=NULL) (*pContext) = pCurContext; if (pPlate!=NULL) (*pPlate) = pCurPlate; }

ColourPlate* EPSRenderRegion::GetOutputColourPlate (  ColourModel  ColModel  )  [protected]

void EPSRenderRegion::GetRenderRegionCaps (  RRCaps *  pCaps  )  [virtual]

This function allows render regions to admit to what they can and can not render. This allows other areas of the program to come in and help render regions out in some situations, if they are unable to render everything. eg. an OSRenderRegion can not render transparancy. Author: Tim_Browse (Xara Group Ltd) <camelotdev@xara.com> Date: 10/4/95 Parameters: pCaps  - The details about what types of thing this render region can render [OUTPUTS] Reimplemented from RenderRegion. Reimplemented in CamelotEPSRenderRegion, and NativeRenderRegion. Definition at line 2435 of file saveeps.cpp. { // This forces line attributes - dash patterns and arrow heads to be output // properly for EPS, rather than using Camelot 'shorthand' tokens. pCaps->CanDoNothing(); pCaps->ClippedOutput = TRUE; }

void EPSRenderRegion::GetValidPathAttributes (   )  [virtual]

Ensure the EPS context has the correct attributes for drawing paths. This required because when the path attributes change, we don't output the EPS commands to reflect this straight away - we set a flag to indicate that the attributes have changed, and then when this function is called, it notices that the attributes have changed, and outputs the EPS commands to select these attributes. This avoids redundant and copious attribute code in our EPS files. (The flags used are ValidPen and FillFlags.ValidGeometry).

Author: Karim_MacDonald (Xara Group Ltd) <camelotdev@xara.com> Date: 23 May 2000 Parameters: pClipAttr  ptr to the ClipRegionAttribute to restore over the current one. [INPUTS] Temp whether the attr is temporary or not. Postscript  is told to restore its last saved context. [OUTPUTS] Returns: Errors: ERROR3 if the current ClipRegionAttribute holds a NULL clip-path ptr. This state of affairs should not happen. You can't set a ClipRegionAttribute with a NULL clip-path ptr, so the only such attr is the default one, and you should never be restoring over _that_. See also: RenderRegion::RestoreClipRegion() Reimplemented from RenderRegion. Reimplemented in AIEPSRenderRegion. Definition at line 2548 of file saveeps.cpp. { // we should never be entered when the current clipattr has a NULL path, as what this // means is that either somebody somehow did a SetClipRegion() with such an attr, or // somebody is trying to Restore() over the default ClipRegionAttribute (which holds a // NULL path ptr). Neither of these actions should occur. if (RR_CLIPREGION()->GetClipPath() == NULL) { ERROR3("EPSRenderRegion::RestoreClipRegion; Current ClipRegionAttribute has a NULL path"); } else { // Update the RR's table of current attributes. RenderRegion::RestoreClipRegion(pClipAttr, Temp); // Get the device context for our export file. KernelDC *pDC = (KernelDC*)CCDC::ConvertFromNativeDC(RenderDC); // export a 'grestore' command. pDC->OutputToken(TEXT("grestore")); pDC->OutputNewLine(); } }

BOOL EPSRenderRegion::SaveAttribute (  UINT32  Index, AttributeValue *  pAttr, BOOL  Temp )  [virtual]

Saves the current attribute on the attribute context stack, and installs the given attribute as the new attribute. If the attribute object is temporary, then it is deleted when the attribute is popped off the stack. See RenderRegion::RestoreAttribute. Author: Will_Cowling (Xara Group Ltd) <camelotdev@xara.com> Date: 20/04/95 Parameters: Index  - Unique attribute ID (See AttributeManager::RegisterDefaultAttribute). [INPUTS] pAttr - the new attribute to use as the current one. Temp - TRUE if pAttr points to a temporary object, FALSE if not. Returns: TRUE if the operation completed successfully, FALSE if not. Errors: Out of memory. See also: AttributeManager::RegisterDefaultAttribute Reimplemented from RenderRegion. Definition at line 469 of file saveeps.cpp. { // Push the current attribute onto the stack, and install the new attribute as // the 'current' one. if (TheStack.Push(CurrentAttrs[Index].pAttr, CurrentAttrs[Index].Temp)) { CurrentAttrs[Index].pAttr = pAttr; CurrentAttrs[Index].Temp = Temp; // Everything worked ok. return TRUE; } // Failed return FALSE; }

void EPSRenderRegion::SetClipRegion (  ClipRegionAttribute *  pClipAttr, BOOL  Temp )  [virtual]

Shrink the RR's clipping region to the region defined by pClipAttr. We do this by: 1. Recording a save-state command. 2. Exporting a description of the clipping path in pClipAttr. 3. Recording a 'clip-to-last-path' command. 4. Recording a 'start-new-path' command, as we don't want our clip-path to get stroked or rendered in any way. Author: Karim_MacDonald (Xara Group Ltd) <camelotdev@xara.com> Date: 23 May 2000 Parameters: pClipAttr  ptr to the new ClipRegionAttribute to set as current in our RR. [INPUTS] Temp whether the attr is temporary or not. Postscript's  context is saved and the commands are output to intersect its [OUTPUTS] current clipping path with that defined by the ClipAttr. Also, the RR's current attr context is updated to use this new ClipAttr. Notes: We mustn't record clipping commands when rendering the default attribute. Therefore this method does *nothing whatsoever* unless pClipAttr's ptr to its clipping-path is non-NULL. This ptr is NULL in the default attr. See also: RenderRegion::SetClipRegion() Reimplemented from RenderRegion. Reimplemented in AIEPSRenderRegion. Definition at line 2492 of file saveeps.cpp. { if (pClipAttr->GetClipPath() != NULL) { // Update the RR's table of current attributes. RenderRegion::SetClipRegion(pClipAttr, Temp); // Get the device context for our export file. KernelDC *pDC = (KernelDC*)CCDC::ConvertFromNativeDC(RenderDC); // export a 'gsave' command. pDC->OutputToken(TEXT("gsave")); pDC->OutputNewLine(); // export a description of the clipping path - data only, please. ExportPath(pClipAttr->GetClipPath(), TRUE, TRUE); // export a 'clip' command. note that if our current winding rule is for even-odd // winding, we must export an 'eoclip' command instead. if (RR_WINDINGRULE() == EvenOddWinding) pDC->OutputToken(TEXT("eoclip")); else pDC->OutputToken(TEXT("clip")); pDC->OutputNewLine(); // export a 'newpath' command. pDC->OutputToken(TEXT("newpath")); pDC->OutputNewLine(); } }

BOOL EPSRenderRegion::WantsGrids (   )  [virtual]

This function is designed to help with the rendering of grids, as they are not always wanted (eg xara eps). EPS classes generally do not want to render grids. The ones that do (NativeEPS) should replace this with a version that returns TRUE. Author: Rik_Heywood (Xara Group Ltd) <camelotdev@xara.com> Date: 12/12/95 Returns: FALSE Reimplemented from RenderRegion. Reimplemented in NativeRenderRegion. Definition at line 2457 of file saveeps.cpp. { return FALSE; }

BOOL EPSRenderRegion::WriteCompressionState (  KernelDC *  pDC  )  [protected, virtual]

This starts the compression process. Called just after we output the document information so that this is not compressed and the galleries can access it easily. In this baseclass version we do nothing as compression would be a very bad thing. Author: Neville_Humphrys (Xara Group Ltd) <camelotdev@xara.com> Date: 19/05/95 Parameters: pDC  - the device context to output to. [INPUTS] -  [OUTPUTS] Returns: TRUE if ok; FALSE if error (e.g. file/disk error) See also: EPSRenderRegion::WriteSetup Reimplemented in NativeRenderRegion. Definition at line 2049 of file saveeps.cpp. { // No compression required here... return TRUE; }

BOOL EPSRenderRegion::WriteDocumentSetup (  Document *  pDocument, EPSFilter *  pFilter )  [protected, virtual]

Browse through the tree, and if a text story is found invoke the document setup function. By only exporting the font setup when necessary, the file size produced is smaller (which makes it easier for me to interpret :) ), and it should hopefully make the filter run a bit faster too. Author: Graeme_Sutherland (Xara Group Ltd) <camelotdev@xara.com> Date: 24/3/00 Parameters: pDocument  - The document being outputted. [INPUTS] pFilter - A pointer to the export filter. -  [OUTPUTS] Returns: TRUE if successful. FALSE if error (e.g. file/disk error) Reimplemented in AIEPSRenderRegion. Definition at line 2119 of file saveeps.cpp. { // Do nothing for normal EPS, only AIEPS files. return TRUE; }

BOOL EPSRenderRegion::WriteEndCompressionState (  KernelDC *   )  [protected, virtual]

This is called once almost everything has been output, just before we output the EOF and we fix the EPS header. In this baseclass version we do nothing as compression would be a very bad thing. Author: Neville_Humphrys (Xara Group Ltd) <camelotdev@xara.com> Date: 22/05/95 Parameters: pDC  - the device context to output to. [INPUTS] -  [OUTPUTS] Returns: TRUE if ok; FALSE if error (e.g. file/disk error) See also: EPSRenderRegion::WriteSetup Reimplemented in NativeRenderRegion.
