L_LTFIL_API L_INT L_ReadFileStamp(pszFile, pBitmap, uStructSize, pLoadOptions)
Reads a thumbnail image stored in a file and loads it into a specified bitmap.
Character string containing the file name.
Pointer to the bitmap handle referencing the bitmap that will contain the thumbnail image.
Size in bytes, of the structure pointed to by pBitmap
, for versioning. Use sizeof(BITMAPHANDLE).
Pointer to optional extended load options. Pass NULL to use the default load options.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
At this time, there are no multipage formats that support stamps.
If you know the file format of the file, you can achieve better performance by calling L_ReadFileStamp2.
