when I was trying to change the resolution of TGA format and then open the image using Photoshop 7.0. I found the resolution always 72. The following is code snippets:

               LBitmapWindow m_BmpSave;
               ///////////////
               m_BmpSave.SetXResolution(m_SimpleData.sDPI);
               m_BmpSave.SetYResolution(m_SimpleData.sDPI);
               ////////////////
               m_BmpSave.Save(m_bmpfilename,FILE_TGA,0,0,MULTIPAGE_OPERATION_OVERWRITE);

Could you tell me where is issues or something else I should do to change the resolution of TGA.

Thanks in advance.

I think you're using v15, right?

In all cases, I don't think the TGA format itself
supports saving resolution information. I opened a 100 DPI JPEG image in
PhotoShop 6 and saved it as TGA. I then opened the TGA also in PhotoShop and checked the resolution, and it was 72.
