42 <h3>Gcolor2 - Select and manage colors</h3>
43 <p>
44 Gcolor2 is a tool to select and retain palette colors. It can be useful for the creation of SliTaz themes,
45 for example. It can be found in the Graphics category or run from the command line:
46 </p>
47 <pre> $ gcolor2 &amp;
48 </pre>
50 <a name="gimp"></a>
51 <h3>Gimp - Manipulate and create images</h3>
52 <p>
53 The GIMP (GNU Image Manipulation) is software that can manipulate images to a very high quality level.
54 It allows you to do what you would expect from an application that processes images, ie. layers, filters,
55 support scripts adding functionality, etc. GIMP supports a large number of image formats such as:
56 PNG, JPEG, XPM, PPM, TIFF, PostScript, PSD, it also offers its own XCF format. To install GIMP:
57 </p>
58 <pre> # tazpkg get-install gimp
59 </pre>
60 <p>
61 GIMP is scalable and can be configured with the main interface - configuration files, brushes and personal
62 scripts are located in the <code>~/.gimp-2.2</code> directory.
63 </p>
65 <a name="gqview"></a>
66 <h3>GQview - Image manager</h3>
67 <p>
68 GQview is very light and quick and allows you to navigate rapidly between images by selecting files
69 in a directory tree with a single mouse click. It supports slideshows, image rotation, adding
70 keywords and tags, drag and drop, and can display EXIF data. It also allows you to edit images
71 in the software of your choice (Mtpaint, GIMP for example). To install GQview:
72 </p>
73 <pre> # tazpkg get-install gqview
74 </pre>
76 <a name="jpeg"></a>
77 <h3>jpeg - JPEG command line tools</h3>
78 <p>
79 To allow applications that use JPEG to function, linked libraries must be provided by the package
80 <code>jpeg-6b</code>, this package also contains some tiny utilities that can be used on the command
81 line such as <code>cjpeg</code> and <code>djpeg</code>. To modify JPEG images on the command line you
82 can also use <code>jpegtran</code>, installed by default on SliTaz, <code>jpegtran</code> allows you to
83 rotate images via the <code>-rotate</code> option. To find out all of the options available for these
84 tools, just specify the <code>--help</code> option. Example:
85 </p>
86 <pre> $ cjpeg --help
87 </pre>
89 <a name="mtPaint"></a>
90 <h3>mtPaint - Image processing</h3>
91 <p>
92 mtPaint is an application for the creation and retouching of PNG, TIFF,
93 XPM and BMP images. It offers many simple, lightweight, fast functions like
94 capture screen (screenshot) which you can access from the menu --&gt; Graphics --&gt;
95 Grab screenshot, or via a terminal:
96 </p>
97 <pre> $ mtpaint -s
98 </pre>
