pdfSetTabLen

int32_t __stdcall pdfGetTabLen(PPDF IPDF);
BOOL32 __stdcall pdfSetTabLen(PPDF IPDF, int32_t TabLen);

function pdfGetTabLen(const IPDF: PPDF): Integer; stdcall;
function pdfSetTabLen(const IPDF: PPDF; TabLen: Integer): LongBool; stdcall;

Purpose. Set/get how many space-equivalents a tab character (\t) expands to when writing text.

Description. Verified write-only no-op. Stores TabLen into FTabLen (default 3, an explicit DIFF from the classic API's default); this field has no consumer anywhere in the text-writing code path — a literal tab character in text passed to any pdfWriteText-family function is not actually expanded per this setting (its handling, if any, is governed elsewhere, not by this value).

Parameters.

Return value. Getter: the stored value (default 3); 0 if IPDF invalid. Setter: True if IPDF valid.
