Function Reference

Page 347 of 821

FreeImageObjEx

Syntax:

LBOOL pdfFreeImageObjEx(

const PPDF* IPDF,

// Instance pointer

const void* ImagePtr) // Image pointer

The function releases memory that was allocated by GetImageObjEx() to decompress the image.

Return values:

If the function succeeds the return value is 1. If the function fails the return value is 0.

FreePDF

Syntax:

SI32 pdfFreePDF(

const PPDF* IPDF) // Instance pointer

The function frees all used resources with exception of the font and external CMap cache. The font

and external CMap caches will be only freed when unloading the DLL or deleting the current PDF

instance to improve processing speed. However, the font cache can be also be freed manually with

the function ClearHostFonts().

There is normally no need to free the used resources by DynaPDF manually except for memory PDF

files. When creating PDF files in memory the internal resources are not freed automatically after

CloseFile() or CloseFileEx() was called. After the PDF buffer was retrieved by GetBuffer() call

FreePDF() to free all internal used resources.

FreePDF() can be safely called at any time so that a PDF file can be deleted if necessary.

Return values:

If the function succeeds the return value is 1. If the function fails the return value is 0. This function

can normally not fail; a return value of zero indicates that an unknown fatal error occurred.

FreeTextAnnot

Syntax:

SI32 pdfFreeTextAnnot(

const PPDF* IPDF,

// Instance pointer

double PosX,

// X-Coordinate of the bounding rectangle

double PosY,

// Y-Coordinate of the bounding rectangle

double Width,

// Width of the bounding rectangle

double Height,

// Height of the bounding rectangle

const char* Author, // Author of the annotation (can be NULL)

const char* AText,

// The visible text of the annotation

TTextAlign Align)

// The text alignment see below
