Description
Obtains a clip region which contains the areas where the given ranges
of text would be drawn. x.origin and y.origin are the same position
you would pass to gdkDrawLayoutLine. index.ranges should contain
ranges of bytes in the layout's text.
Usage
1
gdkPangoLayoutGetClipRegion(layout, x.origin, index.ranges)
Arguments
layout
a PangoLayout
x.origin
X pixel where you intend to draw the layout with this clip
index.ranges
array of byte indexes into the layout, where even members of list are start indexes and odd elements are end indexes
Details
Note that the regions returned correspond to logical extents of the text
ranges, not ink extents. So the drawn layout may in fact touch areas out of
the clip region. The clip region is mainly useful for highlightling parts
of text, such as when text is selected.
Value
[GdkRegion] a clip region containing the given ranges
