Dear puppians,

I recently discovered this command line utility - ImageWorsener - that can crop, rescale and manipulate graphics in high quality. The full version supports WebP and jpg, but I had problems compiling it and commented out the WebP and JPEG sections, so it now produces png files (but can still read a number of different input files). UPXe'd, it is 38k. I compiled it under Lucid, so it should work on recent puppies (except for Racy, it turns out). I am attaching a pet with the executable (/usr/local/bin/imagew) and separate archives for documentation (which you should read, since there are heaps of parameters) and the source (with my modded makefile). The homepage is here: http://entropymine.com/imageworsener/.

Have fun...

With kind regards,
vovchik

PS. It is self-contained and does not require ImageMagick or any large other external library.

He also has some very interesting documentation on his site about issues such as resampling and subpixel rendering.

Dear disciple,

It is good stuff, and his program is very decent. One of these days I will look into the compilation errors I got with the jpeg stuff and try to fix the lib business - unless somebody else wants to. The prog could also use a gui (gtkdialog) front end for those intimidated by all the options. Also a project for another day. Smile

With kind regards,

I've compiled imagew on Lupu 525 without any problem (maybe because it's a different version - 0.9.7). It can resize jpeg images. The runtest script: 7 of 130 failed (2 tests concern webp — I don't have that library; jpeg.jpg is a riddle). If someone wants to test it more thoroughly, I've attached the pet (works on Lupu 525/528; not compressed; docs inside).

Dear Burunduk,

Brilliant. Works fine on my main system (Lucid). Thanks.

With kind regards,

Dear puppians,

Here is a little program I wrote that complements ImageWorsener in that it can create png overlays and can reposition and rescale images, obviating the need for ImageMagick in many cases. It is also tiny, the UPX'd binary weighing it at some 7k! The URL is here: http://www.murga-linux.com/puppy/viewtopic.php?t=75922.

With kind regards,

Ok, this time all tests passed. (Depends on libjpeg-8; compiled statically against libwebp 0.1.3; tested on Lupu 525, 528 and Slacko 531.)

Works fine in dpup exprimo. No need to install libjpeg.so.8. It was already in place.
Thanks.

Dear Burunduk,

Thanks again for this complete version. Works fine in Lucid, too.

With kind regards,
