SetTextObjectFontSize method

Component: TPdf · Unit: PDFium

Edits the native font size of one text object in place

Syntax

procedure SetTextObjectFontSize(Index: Integer; FontSize: Single);

Description

SetTextObjectFontSize writes FontSize into the native text object at Index, changing rendered size without approximating through a matrix transform

Call UpdatePage afterwards so the page scene and renderers pick up the change

Remarks

The call does nothing when the object is not a text object
For whole-object transforms use TransformPageObject; this method only rewrites the font size attribute

Example

Pdf1.SetTextObjectFontSize(ObjIdx, 14);
Pdf1.UpdatePage(1);
