Hi,

I have a similar code to save the plot as PNG or BMP and works, but with the JPEG file it doesnt work (neigther with JPG)

Here is the code
Qt Code: 
  1. QString types(  "JPEG file (*.jpeg);;"
  2.                     "Portable Network Graphics file (*.png);;"
  3.                     "Bitmap file (*.bmp)");
  4.  
  5.  
  6.     QString filter;
  7.  
  8.     QString jpegExt=".jpeg", pngExt=".png", bmpExt=".bmp";
  9.  
  10.     QString suggestedName = "";
  11.  
  12.     QString fn = QFileDialog::getSaveFileName(0, tr("Save 3D Plot"), QDir::homePath()+ "/" +suggestedName, types, &filter);
  13.  
  14.     // If filename is not a null
  15.     // Remove file extension if already there
  16.     if ( !fn.isEmpty() )
  17.     {
  18.         if (fn.contains(jpegExt))
  19.         {
  20.             fn.remove(jpegExt);
  21.         }
  22.         else if (fn.contains(pngExt))
  23.         {
  24.             fn.remove(pngExt);
  25.         }
  26.         else if (fn.contains(bmpExt))
  27.         {
  28.             fn.remove(bmpExt);
  29.         }
  30.  
  31.         if (filter.contains(pngExt))
  32.         {
  33.  
  34.             fn+=pngExt;
  35.             IO::save(m_3dPlot, fn,  "png" );
  36.         }
  37.        else if (filter.contains(jpegExt))
  38.         {
  39.  
  40.             fn+=jpegExt;
  41.             IO::save(m_3dPlot, fn, "jpeg" );
  42.         }
  43.         else if (filter.contains(bmpExt))
  44.         {
  45.  
  46.             fn+=bmpExt;
  47.             IO::save(m_3dPlot, fn,  "bmp" );
  48.         }
  49.     }
To copy to clipboard, switch view to plain text mode 

Any ideas? I doesnt work by changing jpeg by JPEG. Wehn I try to save the plot as jpeg file, no file is created.

Thanks
