Introduction:
GIMP 2.6 is an important release from a development point of view. It features changes to the user interface addressing some often received complaints, and a tentative integration of GEGL, the graph based image processing library that will eventually bring high bit-depth and non-destructive editing to GIMP.
User Interface: Toolbox Menu bar Removed
The toolbox menu bar has been removed and merged with the image window menubar. To be able to do this a window called the empty image window has been introduced. It hosts the menubar and keeps the application instance alive when no images are opened. It also acts as a drag and drop target. When opening the first image the empty image window is transformed into a normal image window, and when closing the last image, that window becomes the empty image window.
Toolbox and Docks are Utility windows:
With the empty image window acting as a natural main window, the default window hints for the Toolbox and Docks have been changed to Utility window. This enables window managers to do a much better job of managing the GIMP windows, including omitting the Toolbox and Docks from the taskbar and ensuring that the Toolbox and Docks always are above image windows.
Ability to Pan Beyond Image Border:
It is now possible to pan beyond the image border, making image window navigation much less constrained. It is no longer a problem to use the edge of a brush on the edge of an image while being zoomed in, and one can adapt the canvas to any utility windows covering parts of the image window.
Brush Dynamics:
Brush dynamics let you map different brush parameters, commonly at least size and opacity, to one or more of three input dynamics: pressure, velocity and random. Velocity and random are usable with a mouse. The Ink tool, that supported velocity before, has been overhauled and now handles velocity-dependent painting much better.Brush dynamics have enabled a new feature in stroking paths. There is now a check box under the "paint tool" option, for emulating brush dynamics if you stroke using a paint tool. What this means is that when your stroke is being painted by GIMP, it tells the brush that its pressure and velocity are varying along the length of the stroke. Pressure starts with zero, ramps up to full pressure and then ramps down again to no pressure. Velocity starts from zero and ramps up to full speed by the end of the stroke.
