Handles the output image data that LFile::LoadTile has written to a buffer.
virtual L_INT LFile::LoadFileTileCallBack(pFileInfo, pLBitmap, pLBuffer, uFlags, nRow, nLines)
Pointer to the FILEINFO structure that contains image information.
Pointer to the bitmap object referencing the bitmap that contains the image information.
A pointer to a buffer object containing one or more lines of output image data that the calling function has already processed (read or decompressed).
Flags that describe whether this is the first or last call of the callback, and whether the buffer contains first or last row of image data. Possible values are:
|FILEREAD_FIRSTPASS||[0x0001] This is the first pass through a progressive JPEG or CMP file.|
|FILEREAD_LASTPASS||[0x0002] This is the last pass through a progressive JPEG or CMP file.|
|FILEREAD_FIRSTROW||[0x0004] The first row of the buffer is the first row of the bitmap.|
|FILEREAD_LASTROW||[0x0008] The last row of the buffer is the last row of the bitmap.|
|FILEREAD_COMPRESSED||[0x0010] The data in the buffer is 1-bit compressed data, which you can handle as explained in Speeding Up 1-Bit Documents.|
|FILEREAD_CLIPVERT||[0x0020] Internal flag.|
|FILEREAD_CLIPHORZ||[0x0040] Internal flag.|
|FILEREAD_UPDATELUT||[0x0080] Internal flag.|
The current bitmap row number of the first line in the buffer object.
The number of lines in the pLBuffer buffer object.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
Override this function to handle the output image data that LFile::LoadTile has written to a buffer.
The FILEINFO structure that gets passed to the this function does not contain the total number of pages. To get the total number of pages, you should call LFile::GetInfo and set the FILEINFO_TOTALPAGES flag.
For an example, refer to LFile::LoadFile.
