Hi guys, Me again. As previously discussed, in order for the new jpeg-2000 plugin to be useful, it is necessary to be able to save images with user selectable compression ratios. I've taken a look at the jpg save setup in GIMP and have noted that there is a quality slider, but, unless I'm missing something (which is possible - I only had a quick look), it is not possible to interactively inspect the compressed image as the slider is moved. This is inefficient because artists won't know what the compressed image is going to look like until they open it up again. It would be far better to be able to adjust the image quality in real time. So, my question - does GIMP provide the ability to do the above in some way or do I need to write code to open a temporary inspection window within the save callback ? Follow on - this is some way off at the moment ... Jpeg-2000 supports rectangular regions of interest (ROI) to enable some parts of an image to be compressed at different levels from others, so for example, a sign with text could be compressed at high quality so you can read it, whilst the background could be more fuzzy, as it's not so important to be able to make out the detail so accurately. Is there some way we can mark rectangular areas that don't get saved in the image, but that are available in the save routine for ROI optimisation ? Layers ? Thanks in advance for any assistance you are able to offer.
