Summary0004024: Get Image Preview too slow for production machines, for magazine/publication etc - doesn't handle big tiffs well
DescriptionWhen inserting an image into scribus, if the photo is a large tiff etc the preview is very slow and almost crashes the machine if you don't give it a while to catch up - mouse doesn't respond etc.

Colleagues of mine on production machines in photo studio often lose patient and crash the system with this.

we use images 5x7", 8x10" and upto 11x14" image sizes at 300dpi and this is a little too much for scribus when inserting the images but it's fine once inserted. Can we please have an enhancement on this to speed up image preview to make accepted for professional use. thanks

Definitely an issue I've seen. We actually create an SCImage for the preview then scale it down and render it. We really need to see if TIFFs can be previewed using downsampling in libtiff or some other fast path ... the current approach is very RAM and CPU time hungry.

-> minor ; I know it's frustrating but every issue is in a way "major". We keep major for _really_ bad stuff.

Ideally we need to read the TIFF progressively and downsample it as we go. libtiff has routines available for partial reads. This could also be useful for helping to contain the general RAM use of SCImage.

It'd also help to know how much RAM these machines have, since it sounds like the problem comes down to excess RAM use forcing the machine to swap.

thanks for excepting this bug - we are using quark in the mean time as we are a photo studio we need to quickly flick through photos and see the preview before importing them for postcards, christmas cards etc but this can crash the system and is too slow currently.

both machine have 512mb or higher ram at work. though we often can have upto 4 applications such as photoshop also running at the same time.

one machine is 64bit however also.

i hope this helps.
