I tried with guidelines but I cannot make them stick to the exact side of the image neither if I tell GIMP they're magnetic. But what's worst is that even if I manually put guides along the edge, it seems that the corners of the perspective tool ignore completely the magnetic attribute. In Photoshop I could simply pick one corner, hold the shift key and restrict movement to the two main axes. Any analog trick in GIMP? In GIMP there's a similar trick for the Move tool: use the arrow keys to move the layer horizontally or vertically. If you press Shift+Arrow keys the movement is in bigger steps (ca. 25 display pixels) -> depending on zoom level you can move across the image in smaller or bigger steps. Unfortunately the arrow key method has some flaws: 1. It can only move the active layer. Picking up a layer doesn't work, because the Shift key is double-bound to 'Tool toggle' and 'Move in bigger steps'. At the end 'Move in bigger steps' wins. Using the mouse to select a layer and the arrow keys to move precisely doesn't work. 2. Moving the currently selected guide doesn't work. Instead the active layer is moved. 3. The arrow keys don't support precise application of the Transform Tools consistently: - Crop Tool: only move the crop area around if it was moved with the mouse before. - Rotate Tool: rotate in steps of 15 degrees, the same way as using Shift+Arrow keys or Ctrl+Mouse - Scale, Shear: up/down arrow keys in-/decrease the value of the selected input field (width, height, shear magnitude) - Perspective Tool, Unified Transform Tool (in GIMP master): no function. As described in another posting the magnetic rulers have the effect to let the mouse cursor snap in at the ruler, not the center of the handler what can be a bit unpredictable and thus unprecise. I could reproduce this with all Transform Tools except the Move and Crop tools.

Would You please explain why. I'm not sure how serious this problems are. Whether it is impossible to set capture radius due to some Gimp/GTK internal restriction or we haven't try it yet? I'm open to any suggestions: how both of us could keep our desired workflow. -- Dominik Tabisz ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list

>thank you Alemelo for bringing up this topic. >Let's not stick with complaints, sitting back and doing nothing. Don't get me wrong, this wasn't a complaint; I just found it strange that this basic behaviour hadn't been implemented yet. Sticking with it, I'd only need an axis lock modifier. I usually correct perspective in architectural photography. While I can easily keep the horizon, well... horizontal, the perspective always make vertical lines slope. To correct those lines I'd need to be able to select the whole image and drag the corners horizontally and not vertically. What I find annoying is that a slight vertical shift when I drag them is almost unnoticeable and after my transformation I will end up with a photograph with a slight oblique margin and I'll be forced to crop it or stretch it to fill again the layer surface. Restricting movement along the axis would cut my work because I would be sure that the image still fills the entire surface. The axis lock could override any problem concerning the point of the handle you click upon, sticking to the corner of the image for reference. This would be what in CAD software is usually called "ortho mode".

Re: [Gimp-user] Restricting tool movement along a single axis
hi Such tool option: "move by guide" / "move by path" would be appreciated. One thing is primary problem: moving tool or handle (like in perspective tool) along single axis. Something like this (or adjusting behavior while pressing Ctrl) would be really usefull. Another thing is to look at this problem from different point of view. IMHO we deal with one example of slightly different problem. Maybe developement is in so early stage that I could suggest slightly different approach. Imagine that we put on our graphic tablet triangle (or any other tool from technical drawing tradition). We could get desired effect of restricting pointer movement. In fact we'd restrict tablet/pointer movement to the edge of template/ruller. In digital graphic we use guides, mesh, paths or selection/quick mask. Each of these tools behave like our virtual template but for different tasks. They mostly affect tools. Why dont make one tool that will affect not tools, but pointer? Why don't add easily adjustable input for this new tool - like paths? We could use predefined "pointer restricting paths" or easily prepare new one by preparing such path in Gimp, Inkscape or any other path creating software. Don't get me wrong - i like idea of improving tools. I would like even more improving them in more "user adjustable way". And i'm pretty aware that every such change will have dramatic consequences in someones workflow. For example Ofnuts mentioned handle behavior in perspective tool. I understand - it's frustrating when You have to precisely catch center of the handle and later move it to guides. On the other hands this behavior let me catch any point within selection and position it in new place. I do a lot such things while adjusting perspective in photographs of paintings, documents etc. - In photographs of my painting i catch the corner of painting, not the corner of photo. I do simple perspective correction to guides - everything around painting will be cut away later. I dont want to reshape selection at this stage, because later another tool is applied (bent between paths). While leaving this behavior as it is - i'll save my fast correction technique, and Ofnuts will be dissapointed. While changing it to automatic moving center of nearest handle to exact pointer location, problem mentioned by Ofnuts will be solved ... and I'll lost my primary tool. When we get some modifier key, that will allow to move pointer to center of a handle instead of moving the handle itself - we will both get our desired functionality. This compromise require change in thinking - we could use pointer as input device, and modify it's XY input. Is such change in understanding pointer behavior possible? Or we are sentenced to compete which workflow, which task is more important? Hope we can find a compromise that will be possible to code.

Yes, with the control key, but not with the perspective tool, which is pretty hard to use in that regard. There's a new perspective tool in the 2.9/2.10 development branch but for me it was pretty useless when I last tried it (I work with images bigger than the screen, and in reverse/corrective mode) and no more accurate. But it's more likely to be improved than the old one. Another problem with the perspective tool is how it behaves with guides. When you click on a corner handle and drag it, what snaps to guides is not the center of the handle, but the point of the handle where you clicked down. This makes it hard to align the handles. ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list

[Gimp-user] Restricting tool movement along a single axis
Hello, as I write in the subject: is there a way to restrict tool movement along a single (horizontal or vertical) axis? I'm not talking about moving objects - as I checked and there's a thread for that - but moving those little squares in the corners of a transform tool selection. Example: I want to change the perspective of a picture. I apply the perspective tool and the picture is overlaid with a grid and four corners. I want to be able to pick a corner - say the bottom right one - and move it *only* right or left, without any vertical shift. I tried with guidelines but I cannot make them stick to the exact side of the image neither if I tell GIMP they're magnetic. But what's worst is that even if I manually put guides along the edge, it seems that the corners of the perspective tool ignore completely the magnetic attribute.
