Using GtkMorph for image editing in Linux

Kindly written by Alexandre

Everybody loves Gimp. I love Gimp too, but there is other amazing image software running under Linux. Have you ever heard about GtkMorph? It is very simple to use. Don´t you believe me? Take a look:

The first thing you need to do is to load an image. Just click the "load image" buttom to choose an image on your system.

Then, go to the fourth bottom, and choose "edit mesh".

Put your hand in the mouse. Left-click somewhere in the image. It will appear a point.

Click the point again, holding the mouse, and move your hand. Do these steps again...

...and again and again... the more you add points and drag then, the more strange your image will be. When you finish, click on the "do wrap" buttom.

Hey, don't I look like a monkey?

...

Now, let's see a program called ImageMagick, used to extract informations from an image. ImageMagick has some options for the command line. Open a shell and type "pnginfo" followed by the name of a PNG image. For example:
#pnginfo /root/myfile.png

The TIFFINFO is designed for the tiff file:
#tiffinfo /root/myfile.tiff

For others image formats, you can use the "identify" command:
#identify /root/myfile.jpg

If you type "-verbose" after this command, the program will return lots of lines of information:
#identify -verbose /root/myfile.jpg

Now, let's say that you wanna add some text on your image in a fast way. You can try the "convert" command:
# convert -font /usr/local/share/fonts/zenda.ttf -fill magenta -pointsize 36 'text 10,50' "Write Something Here" imagefile.jpg give-another-name-here.jpg

Do you wanna rotate your image?
#convert -rotate 90 before.jpg after.jpg

ImageMagick can do even more, but you can take a look in the references below:
