Comparing it with Photodesk 3.14-17 - if I load a sprite and then
save as a JPG it appends /jpg to the filename. If I save a
second time, it is still saved as a JPG with a /jpg extension. I
also notice that the image within Photodesk is still a sprite, so
the user could go back to saving as a sprite (or whatever) if
needed without loss of quality. This seems to be the correct
behaviour to me.
That's the standard state in all the graphics apps I ever used...
Well, yes. DPScan is similar. Once an image is loaded, it is stored
internally as an RGB raster, similar to a sprite. When a save is
performed, the image data is converted to the appropriate format.
However, the actual image data stored internally is not touched by
the save process. Therefore the image quality is not compromised by
saving as a jpeg.
It is really a question of what DPScan should consider as the default
filetype / filename once a save is performed.
