Hi, I'm no GIMP developer, but I will try to code one simple stuff that I think it's useful, snapping guides on the border and center of layers. So, when this is implemented, if you want to get a guide in the center of the canvas, it will be simple as drag a guide when a layer that have canvas size selected. For rule of thirds, I use a gimp plug-in that place them automatically on canvas. check this article by Prokoudine: http://libregraphicsworld.org/blog/entry/advanced-ways-to-create-guides-in-gimpHi! A few thoughts here up for discussion 1. (see Attachment A) Is it possible to add Distance and Angle mesurements to the Paths Tool's /Polygonal mode/? Information could be displayed in the Status Bar just like for the Measure tool. No need for Info window, though. Distance is relative to the previous anchor, angle relative to x-axis or user defined linear segment of another path. Specifying a segment sounds a bit too complicated, so the users would probably have to create two-anchor linear path as a reference axis. Paths Tool (or Measure tool) recognizing varying axes would add extra power to GIMP graphics. It would probably create a mess with the keys assignment but maybe there is a solution for that too? 2. Would be nice to have an option for the Measure Tool to constrain orientation line to integers other than 15 degrees. Say, in the tool options menu checkbox for 1 and 3 in addition to default 15 gedrees. Am I the only one struggling with decimals? Rotate tool has checkbox for 15 degree constraint, by the way. 3 (see Attachment B) Three additional marks on each Ruler corresponding to canvas' exact geometric center and to 'rule of third' imaginary lines. Could be implemented in Cfig filter preview window as well. The ability to snap guides to those marks would also be a must. Could be displayed as notches different in color and shape from standard marks to avoid a confusion. Could be opted as Show/Hide in View/Rulers/hide-show midpoint, thirds. Allows to immediately find geometric center of a canvas, rule of third points of intersection by navigating with a cursor across canvas. Snapping guides to these marks takes less time than: a. Image/Guides/New Guide (by Percent) - Horizontal, 50% (33.3 then 66.6) b. Image/Guides/New Guide (by Percent) - Vertical, 50%, etc., not to mention calculations. I am aware of 3rd party plugin GAT, but many others may not. 4. This idea was actually proposed by a friend of mine who is a professional designer and no stranger to GIMP - a centroid (center of gravity) for irregular shaped selection as a reference point when using transformation tools. Problem with current procedure: rotation/pivot/lever point of Transform tools for some irregular shapes (e.g. L-shaped or boomerang-like selection) is located outside object/selection, therefore, not a centroid. Dragging rotation point over the object without reference point gives inaccurate results. It matters when repetitive trnsformations with the same object is required (e.g. a sequence of objects with different angles of rotation around exact centroid). It's pure math, but I don't know if GIMP has the ability to calculate centroids too. Some of the ideas might have surfaced here before, I can't say I delved too deep to find that out. If need be, more thorough arguments for usability importance can be provided. Perhaps, some ideas are too much for raster based editor. Need your opinions.
