HOWTO: CHANGE BITMAP RESOLUTION

The bitmap resolution can be also very easily changed with gdi+.

The sample below uses the new GdiPlus-X classes from VFPX projects that can be downloaded from here: http://www.codeplex.com/wiki/view.aspx?projectname=vfpx&title=gdiplusx

*!* HOW TO CHNGE THE BITMAP RESOLUTION
* the code loads an image, changes its resolution to 200x200
* and saves it again as a bmp
* http://msdn2.microsoft.com/en-us/library/system.drawing.bitmap.setresolution.aspx

do locfile("System.app") 

with _screen.system.drawing
   * load image to gdi+
   local loBmp as xfcBitmap
   loBmp = .Bitmap.New(getpict())
   * change Bitmap Resolution
   loBmp.SetResolution(200,200)
   * save the bitmap
   loBmp.Save("c:\newresolution.bmp", .imaging.imageformat.bmp)
endwith
