Separate clipped text from unclipped text.
void pdfSetClipText(int clip)
XpdfText normally treats clipped text the same as other text. This can cause problems if the clipped text overlaps other content. If this function is called with a non-zero argument, XpdfText will remove the clipped text before doing layout, and then add it back in afterward. This can be helpful, e.g., for tables where clipped text would overlap the next column.
This setting is global - it applies to all PDF handles.
