Hi Guys,
What is the best way to load an image (JPG file), resize and save it ?

Code: Select all  Expand view
   aBmp  := FW_ReadImage( nil, "c:\fwh\bitmaps\olga1.jpg", { 176, 225 } ) // Load resized image
   FW_SaveImage( aBmp[ 1 ], "olgasmal.jpg", 100 )
   PalBmpFree( aBmp )
 


Original size of olga1.jpg is 352x450 px. Loaded with size 176x225 and then saved.
