Function Reference

Page 346 of 821

The flag fpfImagesOnly can be used to flush the images in memory only. This can be useful if

further objects must be added to the pages in memory or if a large image was inserted.

It is allowed to call the function within an open page. In this case the function does not flush the

content stream of the current open page but anything else depending on the used flags.

Calling a function like DeletePage(), DeleteField() or any other function that deletes a flushed object

results in a damaged PDF file.

Return values:

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

FlushPagesEx

Syntax:

LBOOL pdfFlushPagesEx(

const PPDF* IPDF,

// Instance pointer

TFlushPageFlags Flags, // Various flags

UI32 LastPage)

// Last page that should be flushed or -1

The function writes the pages in memory to the PDF file exactly like FlushPages(). The only

difference is that the last page can be specified. The function calls FlushPages() if LastPage is

smaller 1.

Return values:

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

FreeImageBuffer

Syntax:

void pdfFreeImageBuffer(

const PPDF* IPDF) // Instance pointer

The function frees the buffer of a memory image that was created with the function CreateImage().

FreeImageObj

Syntax:

LBOOL pdfFreeImageObj(

const PPDF* IPDF, // Instance pointer

UI32 Handle)

// Image handle

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

Return values:

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