Return values:

If the function succeeds the return value is 1 and the parameters are filled with values. If the

function fails the return value is 0.

ReadImageFormatEx

Syntax:

LBOOL pdfReadImageFormatEx(

const PPDF* IPDF,

// Instance pointer

void* hBitmap,

// HBITMAP handle

UI32 ADDR Width,

// Width of the image in pixel

UI32 ADDR Height,

// Height of the image in pixel

SI32 ADDR BitsPerPixel, // Color depth

SI32 ADDR UseZip)

// If true, Flate compression should be used

The function retrieves the most important properties of a memory bitmap. All parameters of the

function must not be NULL. The function uses the GDI function GetObject() to retrieve the bitmap

parameters. This function is available on Windows only. Please consider the special treatment of 1

bit images. See ReadImageFormat2() for further information.

Return values:

If the function succeeds the return value is 1 and the parameters are filled with values. If the

function fails the return value is 0.

ReadImageFormatFromBuffer

Syntax:

LBOOL pdfReadImageFormatFromBuffer(

const PPDF* IPDF,

// Instance pointer

const void* Buffer,

// Pointer to image buffer

UI32 BufSize,

// Buffer size

UI32 Index,

// Image index of multi-page image

UI32 ADDR Width,

// Width of the image in pixel

UI32 ADDR Height,

// Height of the image in pixel

SI32 ADDR BitsPerPixel, // Color depth

SI32 ADDR UseZip)

// If true, Flate compression should be used

The function retrieves the most important properties of an image in the same way as

ReadImageFormat2(), but accepts an image buffer as input. See ReadImageFormat2() for further

information.

Return values:

If the function succeeds the return value is 1 and the parameters are filled with values. If the

function fails the return value is 0.
