void OverprintLineAttrValue::Render (  RenderRegion *  pRegion,
BOOL  Temp = FALSE
)  [virtual]
 

Sets the OverprintLineAttrValue attribute for the given render region.

Author:
Jason_Williams (Xara Group Ltd) <camelotdev@xara.com>
Date:
23/7/96
Parameters:
pRegion - the render region to render this attribute into. [INPUTS]
Notes: This attribute is so simple that its state can be read directly off the render region's stack. Thus, there is minimal special render region support for this attribute - we just stack and unstack it directly here.

Implements AttributeValue.

Definition at line 348 of file isetattr.cpp.

00349 {
00350     // Stack the current overprint attribute and set ourselves up as the new one
00351     pRegion->SetLineOverprint(this, Temp);
00352 }

void OverprintLineAttrValue::Restore (  RenderRegion *  pRegion,
BOOL  Temp
)  [virtual]
 

Restores the OverprintLineAttrValue attribute for the given render region.

Author:
Jason_Williams (Xara Group Ltd) <camelotdev@xara.com>
Date:
23/7/96
Parameters:
pRegion - the render region to restore the attribute into. [INPUTS] Temp - TRUE if this is a temporary attribute, FALSE if it is permanent (e.g. it's in a document tree).
Notes: This attribute is so simple that its state can be read directly off the render region's stack. Thus, there is minimal special render region support for this attribute - we just stack and unstack it directly here.
