GIMP :: How To Transform Rectangle Part To Triangle
Aug 27, 2013
I need to transform a rectangle part of my picture to a triangle, linearly, only with horizontal distortion, keeping vertical positions in place. (a rectangle to a triangle standing on its side, by moving the top corners to one point).
I tried the Cage Transform: the top of the picture seems good, but it also distorts the bottom line in this case. Other tools seem not suitable at all.
I wanted to transform only selected part of image and instead all the layers and all the image was transformed by 1800 degree. How to do this what I want to do with the aid of free gimp?
I am trying to create a pattern that I have created in previous itterations of Illustrator. In CC when I create a triangle (either via Star, Poly, or Pen tool) and then try to rotate it via Transform Each > Transform again, the rotation point moves according to what the bounding box would be if I reset it, rather than staying in one (original) spot relative to the actual bounding box and triangle. I cannot find any settings that would be affecting the rotate point in this way. I am pretty confident that I am using the same procedure now that I did in older versions of Illustrator. Perhaps I am using the wrong procedure.
Naturally, if you are rotating something around its center you should expect that it would end up create a circular pattern. It is more of a square with concave sides. The red is a perfect circle that I grouped to the triangle to demonstrate the rotate points movement. It is located in the exact center according to the align tools.
Is there a way to transform a rectangle into a true semicircle? One long side of the rectangle should be preserved, the other long side be transformed into a semicircular curve. The endpoints of the curve will then coincide with the two ends of the opposite side.
I am running the latest version of PS CC on a MacBook Pro OS 10.8.5 with 16GB of ram. When I started my computer this morning an update from Adobe came up so I ran it. Now the move tool and the free transform function are not working. Literally nothing happens when I click drag with the move tool and when I try to use free transform I get an error message I've never seen:
"Could not transform because the initial bounding rectangle is empty.."
I was working on this computer last night using PS on the exact same files and did not run into this problem. Perhaps it was something in the update I ran this morning? The description for the update claimed it added a new version of Camera Raw and added new camera profiles. I don't see how, but its possible that the update effected the way the tools work, or in my case not work.
I've got CS3 and working on a document. I'm typing in text but nothing is coming up on my document. The cursor is not flashing but the text I've written is shown as a layer.
I tried selecting Free Transform and I'm getting the message:
"Could not transform because the initial bounding rectangle is empty"
So when I create a triangle by using the star shape tool and only giving it three points. When I have my triangle, I duplicate it and make it smaller. I center them both up on the canvas, but they don't look centered. As you can see in the picture provided, the bottom has more of a width that the others. I've tried using the alignment tool and the smart guides. I do resize the triangle using shift so it doesn't mess up the shape too.
I made a triangle with the path tool, but then when I fill it with bucket fill the pixels either get filled or not filled. I want the original triangle, which doesn't lie on pixel edges but between edges ([0,16],[8.5,0],[17,16]), to be painted in such a way that if a pixel is partially in the triangle it gets partially painted. I'm working on a 17x16 size image.
I have one problem. I'm using transform tool to scale part of image, but it doesn't look good. Maybe I should use liqify tool but I really don't like it. Here is example of how it looks, at the top left corner of this site [URL]....
I have checked the road map for GIMP and I have seen that the Unified transform tool can be expected in version 3.8. (ugh)
Now what I would like to ask is there any tool or plugin for GIMP that can transform my selections? Or is there any open source image editor that can do it.
I'm not an artist and just for this I have to use Photoshop. For me PS is an overkill for just cutting up an image.
I want to cut the part of the yellow rectangle off the circle. Easy peasy with Photoshop: Layer 1 for the blue circle, Layer 2 for the rectangle, Layer 1 Control + click, then Layer 2, invert selection, delete.
Of course I can delete nodes and adapt the shape to the curve, but I don't know how to cut the figure quickly in Illustrator.
If I was to build a rectangular pipe reducer in parts builder does it have to be built as a structure or could or be a pipe? I am having a hard time understanding how to use part builder. I am trying to work with all the tutorials I can find. I just wish I could find a step by step on how to make a reducer.
I was trying to rotate an image, and after successfully doing so, now I can't exit out of the rotate tool. The layer keeps saying (Transformation). How do I get out of this mode? I want to start duplicating this image and rotating them to different positions, but I need to learn how to get out of this mode.
I'm working on a project with two layers: (1) a photograph, and (2) a line drawing. The line drawing provides the accurate shape, and I need to stretch the photograph to fit the line drawing fairly precisely. The line drawing is the top layer, and I've already added an alpha layer to it so that I can see the photograph through it. Now I need to rotate, scale, and stretch the photograph to fit. Two questions:
--Does Gimp have a tool akin to P$hop's "free transform," which allows you to rotate, scale, and stretch in a single tool before committing the changes?
--Whenever I start using the rotate or perspective tools, the photograph appears on top (even though it's the bottom layer) and I can no longer see the line drawing. Obviously, this makes it nigh impossible to get an accurate fit. Is there a way of preventing this from happening, so that I can see the transparent top layer even while I'm working on the bottom layer?
I'm new here, as well as to script-fu, although I've looked into Scheme and Lisp and know how to program. I'm using Gimp 2.6.12 (the latest version on Linux - Ubuntu 12.04.2)
So, an overview of what I'm trying to do: create a simple clock face (black) with 12 solid white rectangles at the hour marks.
I have a single layer, (black background, white foreground colours), I select a circle, invert the selection and bucket fill.
Then I select a rectangle, fill it, rotate the layer (which cuts out the rectangle, creates a floating selection with it, and rotates that) anchor the flt-sel (and then repeat 12 times).
> (gimp-rect-select image 570 396 25 8 2 0 0) ; select rectangle (#t) > (gimp-bucket-fill layer 0 0 100 0 0 0 0) ; fills the selection (stays selected) (#t) > (gimp-drawable-transform-rotate layer (/ PI 2) 0 400 400 0 2 0 3 0) ; creates a flt-sel, but returns layer instead of the flt-sel(!?) ... (4) ; (also deactivates selection) > (set! fs (car (gimp-image-get-floating-sel image))) ; ... so have to get the flt-sel explicitly 26 > (gimp-floating-sel-anchor fs) (#t)
This kinda works, but doesn't feel like the optimal way to do it . What I was expecting to do is something like copying the selection, 12 x (rotate and add), bucket-fill.
how can I transform a picture, like a landscape, into a curtain? I mean, if I have my picture I want to "blend" it also with shadows, etc... like this effect: URL.... not red, but as on it there is my picture...
How can I move (rotate or otherwise transform) a Selection.
1. Suppose I have a single Layer, on which I draw an image.
2. Now I activate a Selection Tool (Rectangular, Elliptical, Lasso, etc.) and make a Selection.
3. Then I activate the Move Tool and click on the "Move Selection" option, not the "Move Layer" option. [Oddly, when the "Move Selection" option is activated, there are two greyed out (unavailable) sub-options, both indication "Move Selection".]
4. With the Move Tool, I am able to move the Selection, but not the contents of that Selection.
The Gimp Documentation guide says:"If you click-and-drag the selection without handles, you create a new selection! To move the selection contents, you have to hold down Ctrl+Alt keys and click-and-drag the selection. This makes the original place empty. A floating selection is created. The required key commands may differ on your system, look in the status bar to see if another combination is specified; for example, Shift+Ctrl+Alt."
I have tried every combination of Shift, Ctrl and Alt (Shift+Ctrl, Ctrl+Alt and Shift+Alt). None of these allow me to move the contents of the selection. Further, there are no "handles" on the Selection. I suppose the key is to get the handles to appear, but I have not been able to discover the secret combination of keys to make that happen.
Just starting using GIMP today and want to do what I thought should be very simple. I have some images for which I have words that need replacing. I therefor want to take a slice of the background colour and copy that overtop of the text. I have tried to use the rectangle tool to copy and paste the slice. However I am unable to workout how to expand the slice (expand the width) overtop of the text.. I thought it should be a simple matter of dragging the rectangle out to the desired width. I have also tried changing the pixel amount in the Tool options section. how to expand a rectangle?
how to select and modify an EXISTING rectangle (not create a new one)? I drew a rectangle with rounded corners, and now I would like to modify the radius of the corners.
I've tried using the Rectangle Select tool to reselect the existing rectangle, but Gimp only lets me create a new rectangle.
Once i have 'selected by rectangle' and copied its innards how then can i move rect-image to where i want to place it? I am used to just clicking the 'pointer tool / move tool', and move it.
I'm trying to make an eye texture and I have a rectangle texture that i would like to paint in a clockwise fashion, I know that I could just copy and paste + rotate each time but I was wondering if there was a faster way.
I'm trying to crop a rectangle that is slightly off square, so the cropping rectangle is either clipping part of the image or not enough of the empty space. Is there a way to clip a non-rectangular area?
The images are actually parts of a map as a specific projection, and need to be clipped non-rectangular so they match up.
I've created a panel using the rounded rectangle method.
My panel is transparent on the background and I don't like how the edges of it are shown (too rough). I want to add semi transparent pixels after them (a kind of manual anti-aliasing)
I’m trying to figure out if there is a way to scale a “border” around a rectangle or square? Or, put another way, keeping an image the same size, but enlarge an inner rectangle or square without cropping the “border.” To try and add context, imagine a bezel used for an arcade machine. A border with a cut-out in the middle to view the screen. Imagine you wanted to preserve the information on the bezel border, but increase the size of the cut out.
In Photoshop, when I make a selection of an image, the rectangle selection tool stays within the bounds of the image (layer). I would like to do this in GIMP, but the selection is allowed to extend beyond the photo, and basically select blank space.
Basically, I would like to do this so that I can have a fixed ratio box and be able to move it to the very edge of the image without having to worry about making sure the cursor lands exactly on the edge. I'm sure it is a simple option to select somewhere
Refer to the attached file. How can I cut the RED part of the Wall 1 (W1) , where Wall 2 is sloped. I also want to cut a hole in wall 2 (W2) by the BLUE rectangle , but why I can't do that .
I also want to add a second floor to my project but I can only see the" Level" icon goes grey and I can't click it.
