ReplacePageTextEx

Syntax:

LBOOL pdfReplacePageTextEx(

const PPDF* IPDF,

// Instance pointer

const char* NewText,

// New text or NULL to delete the string

struct TPDFStack* Stack) // Operation stack

The function deletes or replaces a text string of a content stream that was found by the function

GetPageText() beforehand. The function requires a font that must be set with SetFont() or

SetFontEx() before calling this function. The new text is internally written with the function

WriteTextMatrixEx().

This function changes certain members of the graphics state such as the fill and stroke color, the

color space and the text draw mode. If further contents must be written to the file make sure that the

color space, text draw mode, and the wished fill and stroke color is initialized with the wished

values before writing new contents to the file.

DynaPDF is delivered with the example edit_text which demonstrates how texts can be replaced in

a document. If you want to develop a text replacement algorithm please take a look into this

example.
