    Picture loss issue when resizing

    swany4

      Has anyone experienced an issue when using the image size function to reduce the size of a jpg or png?

      When I make a picture smaller (eg. 100x75px) from a much larger image (eg. 500x375px) or even larger using the image size function with the constrained option I been noticing the quality of my pic get's really bad.

      But when I resize it myself by dragging a corner to the proper size the quality is much better.

      Is this normal for Fireworks?

          Quality loss is normal for any app when resampling an image. Typically 

          you will want to apply unsharp masking after scaling down, but you can 

          also change how Fireworks resamples the image by going to the 

          preference dialog. That change may be enough.

           

          In the general tab, try setting the Interpolation to Bicubic and make 

          sure that "faster but less accurate resampling" is deselected.

           

          If the results still aren't satisfactory you can try Photoshop, which 

          has a couple other resampling algorithms to choose from.

           

          Another interesting option for Fireworks is to first convert the hi-

          res image to a graphic symbol, then scale the file. This option also 

          gives you the freedom to constantly resize the image with no 

          additional quality loss, so long as you don't exceed the original 

          image size.

            Jim, thanks.

            Using bicubic or converting the pic to a graphic symbol worked. Scaling down works a lot better.
