Feature Request: Faster JPEG loading
Posted: Tue Aug 05, 2008 6:07 am
Hello everybody!
I enjoy xnview pocket very much on my Fujitsu-Siemens N560 and I would like to use it as a picture frame/picture slide show viewer. The pictures I normally view using xnview are holiday photos about 700k-1.2M in size. Unfortunatelly, I like viewing the images in full screen mode (as slideshow) and they take about 2 seconds to load and render. The image resolution is about 1600x1200.
I've tried with other programs (PDAMill Viewer for instance or SPB Imageer) and it loads and renders the images pretty quickly (in about 0.5 seconds), so the limitation isn't in the storage card speed.
Is there anything you can do to speed up jpeg rendering? I'm thinking other programs don't decode the whole file and thus are faster (and the quality difference on a small display isn't that upsetting).
If you choose to implement this fast jpeg rendering, it should probably be as an option.
I realize this may be a lot of work, but maybe you can tune some parameters in the jpeg rendering process and obtain a faster decoding speed.
Thanks for this great program and support!
