Detects whether the image that was last loaded has an error.


#include "l_bitmap.h"

L_LTFIL_API L_INT L_GetLoadStatus();


Value Meaning
SUCCESS The image loaded by the last load call does not have any errors.
ERROR_COMPRESSED_DATA_FAILURE There were errors decoding the last image. The bottom part of the image might be corrupted.
ERROR_BAD_RESYNC_MARKER Some of the resync markers were incorrect or missing while decoding the last image. Resync markers are used by JPEG files to recover from decoding errors. Portions of the image are corrupted. They are indicated by a checkerboard pattern.
ERROR_FILE_READ The file was truncated. The bottom part of the image is missing.
ERROR_PDF_BAD_CONTENT The file may not been loaded completely or it may have missing parts.
< 1 Another error occurred while loading the last image. Refer to Return Codes.


The returned error code describes a warning that portions of the image that was last loaded might be corrupted.

This function should be called after a load function returned SUCCESS. This value is reset after each page is loaded, so if you are loading multiple pages, this error code is valid only for the last page.

If the last load function returned an error code, then this function should not be used, as its return value is undefined.

Note that the return value is valid for the current thread. So L_GetLoadStatus should be called in the same thread as the load function.

This function is valid for all of the functions that will load a bitmap. Examples of such functions: L_LoadBitmap, L_LoadFile, L_LoadFileOffset, L_FeedLoad, etc.

Required DLLs and Libraries
