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

Code: Select all  Expand view  RUN

   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.

Previous there has been issues about the saved quality. (time ago) Is this current way keeping the quality good ? Will test it, but general speeking ....?
