IG_save_mem

This function saves the image referenced by hIGear to a memory buffer using user-defined callback functions.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_save_mem_CB( LPVOID lpImage, AT_UINT nImageSize, AT_UINT nBufferSize, UINT nPage, UINT nReserved, AT_LMODE lFormatType, LPFNIG_RASTER_GET lpfnRasterGet, LPFNIG_DIB_GET lpfnDIBGet, LPVOID lpPrivateData, LPAT_UINT lpActualSize );

Copy Code

AT_ERRCOUNT ACCUAPI IG_save_mem_CB(
   LPVOID lpImage,
   AT_UINT nImageSize,
   AT_UINT nBufferSize,
   UINT nPage,
   UINT nReserved,
   AT_LMODE lFormatType,
   LPFNIG_RASTER_GET lpfnRasterGet,
   LPFNIG_DIB_GET lpfnDIBGet,
   LPVOID lpPrivateData,
   LPAT_UINT lpActualSize
);

Arguments:

Name	Type	Description
lpImage	LPVOID	Memory buffer to which to save the image.
nImageSize	AT_UINT	Size of the image if it already exists in the buffer, 0 otherwise.
nBufferSize	AT_UINT	Size of the memory buffer.
nPage	UINT	If saving to a multi-page file, set this to the page number to insert this page as. Note that page numbers begin at 1, not 0. Otherwise set to 1.
nReserved	UINT	Reserved, should be set to 0 for now.
lFormatType	AT_LMODE	Specifies the format to use for saving, and also the compression scheme if applicable. See enumIGSaveFormats.
lpfnRasterGet	LPFNIG_RASTER_GET	Pointer to a function of type LPFNIG_RASTER_GET, which will be called for each raster line of the image, before that line is saved.
lpfnDIBGet	LPFNIG_DIB_GET	Pointer to a function of type LPFNIG_DIB_GET, which will be called just prior to saving the DIB header.
lpPrivateData	LPVOID	Pointer to a private data area which is passed to the above two callback functions each time they are called.
lpActualSize	LPAT_UINT	Actual size of the image is returned in the variable referenced by this pointer. Can be NULL.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

Indexed RGB - 1, 4, 8 bpp;
Grayscale - 9...16 bpp;
RGB - 24 bpp;
CMYK - 32 bpp.

Actual set of pixel formats supported by this function can be narrower, depending on the implementation of the user-defined callback functions.

Remarks:

This function is only kept for backward compatibility reasons. Please use IG_save_mem_CB_ex instead.
