Requires Gtk2, was compiled in Puppy 3.

If the binaries do not work in your Puppy, you can compile them like this:

cd /usr/local/Scale2pics
./install

usage: (scale2pics)

This converts a whole folder.

scale2pics /usr/share/backgrounds /root/testpics/ 30 20 85 jpg
(the targetfolder may not exist yet)

This will do:
- create a folder /root/testpics/
- create in this folder scaled jpg-files with a maximum size of 30x20 pixel, with 85% quality from all pictures in /usr/share/backgrounds.


usage: (scale2pic)

This converts a single file.

scale2pic /usr/share/backgrounds/default.jpg /root/testpics/output.png 30 20 60
(the targetfolder here must exist already)

Supported input formats: did not try, at least these work: xpm, png, bmp, jpg

Supported output-formats: png, bmp, jpg, ico (NOT xpm!)


----------------------------------------
Both are scripts.
They use 4 binaries. To see how those work, you can look at the script:
/usr/local/Scale2pics/example

Note: the scripts keep the aspect-ratio.
if you have a source of 320x200, and give as targetsize 32x1000, then you will get 32x20, as the sizes define the maximum values, if the aspectratio allows them.
This is very fine, if you want to batch-convert pictures for websites, where pictures should never be higher or wider than 50px for thumbnails.

Sorry for bumping old thread but this is a great little .pet

thanks.

Dear Puppians,

I did this a while back and seems to work. It is also pretty small and can be used in scripts for rescaling various file types using only gdk calls (like Mark's). Please have a look http://www.murga-linux.com/puppy/viewtopic.php?mode=attach&id=34335. I included a binary.... The reason I did this was because, as I recall, Marks version did not handle the alpha channel (png transparency) properly.

With kind regards,
vovchik
