introduction

This analysis its the result all of our work on GIMP up to now, and shows the way forward for each aspect of GIMP UI, in the form of solution models.

GEGL

windows, toolbox, inspectors

heads-up displays

zooming and scrolling

the toolbox

the brush tools

  • make the four main brush modes (airbrush, nib, pencil, paintbrush) sub-modes of every type of brush tool, not just of color painting;
  • create the opportunity to move the four main brush modes to be more algorithm based for further refinement. Bitmaps for brush shapes will play a more secondary role (for special jobs) in the future;
  • complete the palette of type of adjustments that can be made with a brush:
    • saturation
    • distortion
  • merge cloning and healing;
  • take a less generic approach for what options are available for a certain brush type;
  • discuss the historic significance of the modes parameter, and its future;
  • introduce a way of painting with the effects of plugins. Probebly via the blobs-of-paint concept;
  • review of the shortcut actions to change brush parameters.

the geometry tools

  • we have to do our utmost to get rid of the layer/path/selection modes;
  • there is a big opportunity for speeding up interaction by merging most of the geometry tools (move, rotate, scale, shear, perspective, flip) into one geometry tool; the icon for this tool can be a mouse pointer;
  • we evaluated that there is casual rotation, just by the eye, but also critical rotation, adjusting horizons for photographers; the same for perspective; this points toward that the casual rotation and perspective goes in the general geometry tool, and there still need to be two specialised critical rotation and perspective tools optimised for photographers; to be discussed: is there also critical shearing?
  • in the general tool, the different actions either work by providing dedicated handles, or by invoking a mode via a clickable on/off icon (HUD):
    • move + scale: handles like the new selection tools;
    • rotate: either a mode or a single circular handle that rotates around the centre point;
    • shear: either a mode or four handles mid-point of the sides of the bounding rectangle;
    • perspective: mode;
    • flip: two HUD buttons, just do it;
  • all these geometry actions can be merged also into the oval/rect selection + crop tools, for set-up.
