To saveimages in MIME image formats,you have to choose the Exportoption from the file menu.That sums up GIMP’s changes in theuser interface department. However,many bold changes in the newrelease not only enhance the editingexperience but also pave the way forfuture GIMP development.Layer GroupingThe most painful part in editing andcreating huge images are layers. Animage is an amalgamation of manylayers, and managing images withmany layers can be a daunting task.To provide an easy workaround,GIMP 2.8 boasts layer groupingfeatures. You simply create a newgroup, and if you want to addlayers, simply drag and drop intothe layer group.Inside the layer group, you cancarry out all the generic layer-relatedtasks, so these new groups don’tlimit your editing.Resource TaggingTagging is an efficient way to locatedata, especially if you have severalplugins, brushes and gradientsinstalled. GIMP 2.8 lets you easily tagresources that allow you to navigatequickly through the massive resourcesat your disposal.Figure 7.

The most importantis support for OpenCL. With supportfrom AMD and a GSOC project,GIMP now scales with graphicsprocessors for image processing,which makes a normal imagefunction much faster.GIMP, being an image editor,requires you to work with arrayWWW.LINUXJOURNAL.COM / DECEMBER <strong>2012</strong> / 105
