Hello forum!
I scan a color document in B/W mode and get an image, that cutted on the corners (s.Attachment). For encoding I use the ijl15. This is my EncodeJPGFileFromDIB method:
BOOL WINAPI EncodeJPGFileFromDIB(LPCSTR lpszPathName,LPBITMAPINFOHEADER bmih) { BOOL bres = FALSE;
JPEG_CORE_PROPERTIES jcprops;
DWORD dib_pad_bytes;
if (bmih ) {
__try { IJLERR err = ijlInit(&jcprops);
if (err == IJL_OK){
BOOL bColorDib = bmih->biBitCount > 8;
DWORD dwColorSize = (DWORD)(BmiColorCount(bmih) * sizeof(RGBQUAD));
jcprops.DIBBytes = reinterpret_cast(bmih) +
bmih->biSize +
dwColorSize;
jcprops.DIBWidth = bmih->biWidth;
jcprops.DIBHeight = abs(bmih->biHeight);
jcprops.DIBHeight *= -1; // Otherwise the bmih is upside down
jcprops.DIBChannels = bmih->biBitCount / 8;
jcprops.DIBPadBytes = IJL_DIB_PAD_BYTES(bmih->biWidth, jcprops.DIBChannels);
jcprops.DIBColor = bColorDib ? IJL_BGR : IJL_G;
jcprops.JPGFile = (LPTSTR)lpszPathName;
jcprops.JPGWidth = bmih->biWidth;
jcprops.JPGHeight = abs(bmih->biHeight);
jcprops.JPGChannels = bmih->
biBitCount / 8;
jcprops.JPGColor = bColorDib ? IJL_YCBCR : IJL_G;
jcprops.JPGSubsampling = bColorDib ? IJL_411 : IJL_NONE;
jcprops.jquality = nJpegQuality; // Defaults to 75
// Remove the file form the temp area beforee wiring a new one
DeleteFile(lpszPathName);
err = ijlWrite(&jcprops, IJL_JFILE_WRITEWHOLEIMAGE);
if (err == IJL_OK) { bres = TRUE;
}
}
} // end try
__finally
{ // Clean up the Intel JPEG Library.
ijlFree(&jcprops);
}
}
return bres;
} // EncodeJPGFileFromDIB()
What is wrong? Where could be an error?
Thx, Alex
