I do wish mtpaint had some command line options to access some its features. Topmost would be image conversion. It's really easy to open any image format it supports and save it as another, but if you could specify it at the command line, we could use it for batch processing... amongst others.

Once upon a time, Mark Tyler made a library from modified mtPaint sources, and it included, among its example programs, a commandline-driven image processing app 'mifcon'. This is the "libmtpixel" package on Sourceforge.
Problem was, the interfaces got bitrotten almost immediately, so there was no hope of cheaply integrating this into the core project, and no one of us wanted to maintain libmtpixel as a fork. So it remained stuck at version 0.40 (forked off mtPaint 3.14.42).
If I copied the commandline-handling part of 'mifcon' into mtPaint, it would add about 30-35 kb to binary size.

To resize the clipboard--->
Select a portion of a picture.
Put selection in a numbered clipboard.
mtpaint allows multiple clipboards.
Using Rox-filer go to /root and see the hidden files.
...

When done right, it's a lot less intimidating than that. Wink
- Copy the portion of image to clipboard;
- Do 'Edit->Paste to new layer';
- Resize that layer;
- Copy it whole to clipboard;
- Switch to the original layer and paste.

... but how many other binaries could it eliminate? probably 10 times that
all of the *to*, jpeg*, png* convert(and others from imagemagick) exactimage ... too many to name - its too bad it got forked into bitrot

many of these tools do a mediocre job and i find myself having to use mtpaint manually anyways

... same goes for the -v option - a few kb there (mostly gui) could replace the image viewer

I've been practising using a new upper layer to do rescaling and
hue changes. I wrote a tutorial.
