I have been looking into PortableApps (http://portableapps.com/) for use at work and I found a program called PNGOptimizer (http://psydk.org/PngOptimizer.php). I was wondering if we have any apps with similar functionality in synaptic.

Try gimp as it closely resembles the functions of photoshop and can resize and change formats for many types of pictures as well as edit them. It is probably the #1 Linux picture application and is in the repositories.


Hope that works for you

Hope that works for youYeah I use the Gimp but I didn't realise it could optimise images in this way. Is that related to the compression level when you save a file.

I have proven to myself that Gimp can, in fact, do this. As a little experiment I took a 80x60 png file I had that was 24.69kb and saved as default except interlacing checked. I then saved a copy of it unchecking everything except interlacing and the file size became 10.6kb. I saved another copy and unchecked interlacing as well and the file size became 8.9kb.

The reason I have asked this question is that I use these images on web sites and could do with the smallest size possible. Can someone give me a link to discussions/tutorials on the optimisation of image files. For instance I thought that interlacing was a good thing for web images but does it justify the extra 1.7kb. Not much for one image you may think but if you have 20 on a page it starts to mount up.

Appreciate any links posted.
