I am trying to color only black pixels in a tif file.  It seems to work ok when I resize the bitmap in half, but when I try and paint the file without resizing, it just paints the whole file black.  I tried both Load() and LoadResize(), and all the functions return success, but the file is painted completely black.  I have attached the tif file I was testing with.  I am using Raster Pro, Version 14.5.  Thanks in advance of any help.  Here is my code:

  LBase::LoadLibraries(LT_ALL_LEADLIB);

  CString PageLocation = "C:\\Test\\Test.tif", NewPageLocation = "C:\\Test\\Test_NEW.tif";

  LFile        LeadFile;
  FILEINFO     fInfo;
  LBitmapBase * pBitmapBase = new LBitmapBase();

  LeadFile.SetFileName((L_TCHAR*)(LPCTSTR)PageLocation.GetBuffer(1));
  if( LeadFile.GetInfo(&fInfo, sizeof(FILEINFO)) == SUCCESS )
  {
   // This works
   //int LoadStatus = pBitmapBase->LoadResize((L_TCHAR*)(LPCTSTR)PageLocation.GetBuffer(1), fInfo.Width/2, fInfo.Height/2, 8, SIZE_NORMAL, ORDER_BGR, NULL, NULL);
   
   // This Doesn't
   int LoadStatus = pBitmapBase->LoadResize((L_TCHAR*)(LPCTSTR)PageLocation.GetBuffer(1), fInfo.Width, fInfo.Height, 8, SIZE_NORMAL, ORDER_BGR, NULL, NULL);

   if( LoadStatus == SUCCESS )
   {
    LBitmapRgn Region(pBitmapBase);
    int Status = Region.SetRgnColor(RGB(0,0,0)); // set the black color as a region
    if( pBitmapBase->HasRgn() == TRUE )
    {
     pBitmapBase->Fill(RGB(50,177,205));  // Fill the black region this color
     int error = pBitmapBase->Save((L_TCHAR*)(LPCTSTR)NewPageLocation.GetBuffer(1), FILE_TIFLZW, 8, PQ1, 0, NULL );
    }
    Region.Free();
    pBitmapBase->Free();
   }
  }

Thanks,

Rich

Can you resend the image that you wanted to send? Please put the Tiff image in a ZIP or RAR file so that our forum will allow posting it.

Also, if possible, can you send me your code in a small test project (not your full application) so I can check it for you?

Here is the image file as a zip file.  Once again thanks for looking into this.

Adnan,

Thanks for looking into this.  I have attached the zipped and attached the source code, and image file that is not working.  The code is c++.  For some reason when you load in the file at 1/2 the size painting the black pixels and saving the file works.  But when you load at the full size with the same function, the saved file is completely black.

Thanks,

Rich

Rich,


It seems the source code you sent uses MFC in a console
application. Please either send me the remaining files of this test project, or
at least tell me which version of Visual Studio you're using so that I can create my own project.

Adnan,

 

Here is the full project, with files.  Please note the tif file goes into a c:\test directory.  Once again thanks for looking into this.  There seems to be something with how large of a file can be colored by region.

 

Thanks,

Rich

You will find attached
2 TIFF images generated using your code(one from each function call). I was able to successfully open them using our Main API demo. If you use our demo to view the files, do they work correctly?
