pdfGetLastTextOffset

Purpose — Byte offset within the current page's content stream where the most recent text-showing operator was written.

Declarations

uint32_t __stdcall pdfGetLastTextOffset(PPDF IPDF);

function pdfGetLastTextOffset(const IPDF: PPDF): Cardinal; stdcall; external 'LumasPdf.dll';

Return value — Byte offset (content-stream size at the moment the show operator was about to be written); 0 if no qualifying write has occurred yet or the handle is invalid.

Remarks — Updated only by pdfWriteText/Ex — confirmed by tracing every assignment site of the backing field, all four of which are inside WriteTextA/WriteTextW. Writing via pdfWriteFText, pdfWriteTextMatrix, or pdfWriteAngleText does not update this value — the same scope limitation documented for underline drawing in E02.
