Here is the description of mtpaint :

mtPaint is a simple painting program designed for creating icons
and pixel-based artwork. It can edit indexed palette or 24 bit <a class="zem_slink" title="RGB color model" rel="wikipedia" href="http://en.wikipedia.org/wiki/RGB_color_model">RGB
images and offers basic painting and palette manipulation tools.
Its main <a class="zem_slink" title="File format" rel="wikipedia" href="http://en.wikipedia.org/wiki/File_format">file format is <a class="zem_slink" title="Portable Network Graphics" rel="wikipedia" href="http://en.wikipedia.org/wiki/Portable_Network_Graphics">PNG, although it can also handle <a class="zem_slink" title="JPEG" rel="wikipedia" href="http://en.wikipedia.org/wiki/JPEG">JPEG, <a class="zem_slink" title="Graphics Interchange Format" rel="wikipedia" href="http://en.wikipedia.org/wiki/Graphics_Interchange_Format">GIF,
TIFF, <a class="zem_slink" title="BMP file format" rel="wikipedia" href="http://en.wikipedia.org/wiki/BMP_file_format">BMP, <a class="zem_slink" title="X PixMap" rel="wikipedia" href="http://en.wikipedia.org/wiki/X_PixMap">XPM, and <a class="zem_slink" title="X BitMap" rel="wikipedia" href="http://en.wikipedia.org/wiki/X_BitMap">XBM files.

So, it looks like a good tool to create icons and artwork. But we can use this to do some stuff with our <a class="zem_slink" title="Digital image" rel="wikipedia" href="http://en.wikipedia.org/wiki/Digital_image">digital images also. I will show you some examples below, but before that let us install the program:

sudo yum install mtpaint

Now, the initial screen looks like this:

<a href="http://blog.amit-agarwal.co.in/wp-content/uploads/2009/09/Screenshot.jpg"><img class="size-thumbnail wp-image-1405" title="Screenshot" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/Screenshot-150x150.png" alt="Screenshot" width="150" height="150" />

There is transform color in the menu, this can be used to adjust the Gamma, brightness, Contrast and so on. Will really help to fix up these things before going any further with the image.

<a href="http://blog.amit-agarwal.co.in/wp-content/uploads/2009/09/screenshot_001.jpg"><img class="size-thumbnail wp-image-1406" title="screenshot_001" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/screenshot_001-150x150.jpg" alt="screenshot_001" width="150" height="150" />

Now we will look at the edge detect. There are couple of options here that you can try.  The output after applying one of these would look something similar to the next image.

<a href="http://blog.amit-agarwal.co.in/wp-content/uploads/2009/09/screenshot_002.jpg"><img class="size-thumbnail wp-image-1407" title="screenshot_002" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/screenshot_002-150x150.jpg" alt="screenshot_002" width="150" height="150" />

<a href="http://blog.amit-agarwal.co.in/wp-content/uploads/2009/09/screenshot_003.jpg"><img class="size-thumbnail wp-image-1408" title="screenshot_003" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/screenshot_003-150x150.jpg" alt="screenshot_003" width="150" height="150" />

Now we have the difference of Gaussian effect. This also helps you give a different look to your images. Example below:

<a href="http://blog.amit-agarwal.co.in/wp-content/uploads/2009/09/screenshot_004.jpg"><img class="size-thumbnail wp-image-1409" title="screenshot_004" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/screenshot_004-150x150.jpg" alt="screenshot_004" width="150" height="150" />

<a href="http://blog.amit-agarwal.co.in/wp-content/uploads/2009/09/screenshot_005.jpg"><img class="size-thumbnail wp-image-1410" title="screenshot_005" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/screenshot_005-150x150.jpg" alt="screenshot_005" width="150" height="150" />

And for the final image I have the Embrossed image.

<a href="http://blog.amit-agarwal.co.in/wp-content/uploads/2009/09/screenshot_006.jpg"><img class="size-thumbnail wp-image-1411" title="screenshot_006" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/screenshot_006-150x150.jpg" alt="screenshot_006" width="150" height="150" />

Rest I will leave to your imagination. There&#8217;s not much you can do anyway as this is not designed with this purpose in mind.<h6 class="zemanta-related-title" style="font-size: 1em;">Related articles by Zemanta <ul class="zemanta-article-ul"> <li class="zemanta-article-ul-li"><a href="http://www.makeuseof.com/tag/the-top-3-batch-picture-manipulation-apps-to-batch-rename-convert-and-resize-your-photos/">The Top 3 Batch Picture Manipulation Apps To Batch Rename, Convert And Resize Your Photos (makeuseof.com) <li class="zemanta-article-ul-li"><a href="http://greg.org/archive/2009/11/02/digital_to_analog_paint_matching.html">Digital To Analog Paint Matching?
