Re: Resize images

Hi Miguel,

I have implemented imageop, however, the only samples that work are:

  * Display image with original size and colour
  * Tint image various colour

I get "Unable to transform src image" for

  * Image scaling
  * Image resize

Any ideas how to get scaling and resizing working

Best wishes

Peter
