List of all members.

Public Member Functions
	BitmapPreviewData ()
	Constructor.
	~BitmapPreviewData ()
	Destructor.
void	DeleteBitmapData ()
	Removes all the data of the object, but only if its not shared with other objects of the same type.
void	SetNewBitmap (KernelBitmap *pKernelBitmap, UINT32 FileSize, BitmapExportOptions *pOptions)
	Receives a new bitmap (and its file). Deletes the previous bitmap and file (if any) set for that object.
void	GenerateBitmapInfoStrings (String_64 &ImageSize, String_64 &FileSize, BOOL bIncludeBpp=FALSE)
	Removes a fileGenerates image size and file size info strings.
void	CalculateTime (String_64 &timestring, double)
	Calculates the time to download the bitmap.
BOOL	GenerateHTMLStub (BrowserPreviewOptions BrowserOptions)
	Generate a html file which includes our bitmap, together with some other optional stuff. Used for browser preview.
Static Public Member Functions
static BOOL	ComposeHTMLColour (DocColour *pColour, String_32 &OutColour)
	Converts from a DocColour to a colour string in html format: "#rrggbb", where rr - the red component, gg - the green, and rr - the blue. All the components specify a hexadecimal value in the 00 - ff range.
static BOOL	ExportBrowserTypeBitmap (KernelBitmap *pBmp, PathName *pOutFile)
	Exports a kernel bitmap to a gif file, the gif preview filter is used, so that no export options dialog box is displayed.
static BOOL	ExportImagemap (CCDiskFile &DiskFile, PathName *pPath, SelectionType Sel, DPI dpi, ImagemapFilterOptions ifoOptionsToUse)
	Generate a imagemap for our bitmap, and writes it out to our html page.
static BOOL	SetBackgroundFromPage (CCDiskFile &DiskFile, Spread *pSpread=NULL)
	Gets the current page background from the current document and generates an HTML string which displays the same background on the HTML page. If a spread has been specified then use that instead of the current document. See Also: BitmapPreviewData::ComposeHTMLColour, BitmapPreviewData::ExportBrowserTypeBitmap.
