GIMP :: Scale Selection Per Script
Sep 21, 2013
How can I scale a selection fast and easy within a python-script, so fast as I would do within the Gimp-interface: Toolbox->Scale->set Transformation to Selection->scale the selection and ready...
First I have tried
sel = pdb.gimp_selection_save(myImg)
pdb.gimp_item_transform_scale(sel,...)
pdb.gimp_image_select_item(myImg,0,sel)
But it takes some seconds! (gimp interface method needs milliseconds).
When I omit the first step (no selection_save first), then there will be a floating selection, and that isn't really what I want.

Is there a plugin that allows real-time rotate/scale of a selection (like in photoshop) ? The way it works stock is the only annoying thing in gimp that makes my work unnecessarily harder.

I'm trying to scale a pattern to fit the entire canvas without tiling it over the whole layer. To try to do this, I made a rectangular selection box, then dragged and dropped a pattern into the box. This created a new layer called "clipboard". I right clicked the clipboard layer, then left clicked "Scale Layer". Then I entered a width and height in pixels that matched the size of the canvas. The selection does expand, but it doesn't fill the entire canvas.

I notice with GIMP 2.8 that I can't type in numeric values if I want to scale/rotate/etc. a selection. I can use the mouse to manipulate my selection freely, but I'm pretty out of luck if I want an exact value (though I know that I can hold Ctrl for certain snapping, which is extremely useful).

When I'm editing pix, and need a quick large solid brush for a couple seconds, (1-inch dia), I slide "scale", but it's nearly impossible to manually rest scale back to default without restarting Gimp...
Can there be a dot-button beside scale that auto-sets scale back to default..? and/or a timer on scale changes that resets scale back to default after ten-seconds..?

Right after one makes a selection, say by using the Rectangle SelectTool, is presented with handles that allow altering the selection.
If one then selects another tool without deselecting is being deprivedof these handles while the selection remains active thus rendering himunable to alter the selection in that fashion.
Thus forming my question: is there a way to make these handles to(re-)appear on a non-freshly created selection?

I know how to blend selection edges of a selection in Gimp 2.8.2, but if I have only one side of a selection that needs blending, what should I do?
Lets say that I have a grey box on a black background and only want to blend the left vertical edge into the background.

I selected a layer in order to scale it. When I click the link between height and width and then change the percentage up or down the object I'm trying to scale simply disappears. I can see the edges and the transform tool 'handles' but the layer is not there. I've never had an issue in any other version of Photoshop. What the heck is going on?
Doesn't matter whether I use the percentage tool in the upper palette of Photoshop or just shift and drag to scale. The scaling object becomes invisible.

When I select an image against a solid background to convert it to a transparent background, there are often extra half-background pixels due to the anti-aliasing. Is there a way to either a) scale the selection toward the center instead of from a corner, or use a smarter selection tool to outline an object and convert anti-aliased pixels to their semi-transparent equivalents?

If I select a "New" document in CS5 I find that I am only able to paint or fill in in grey scale. This is new. In the Color options panel the grey scale slider is ticked and all other options are greyed out.
How do I remove the tick by the side of the grey scale slider and make the other options available for selection as normal. I note that if I open a previously opened document all options are available it just seems to be new blank documents.

After pasting in a PNG, and it's made into a Floating Selection layer, she wanted to scale it down using the Scale tool. So she clicked and dragged till she got the right size, but upon clicking on Scale (in the little dialog that pops up with the Scale tool), the dialog box vanishe ... and the layer went back to its original size. She tried multiple times and got the same problem.
I even got her to click on "Cancel" rather than Scale in case it was a traslation error, like the translator mixed up the Scale and Cancel buttons, but nope.

For some reason, when I bring up the scale tool, the toolbox appears to the right of the screen, half cut off and under the Gnome toolbor. I've tried moving it, but it is being stubborn. This appears to be the only box having this problem, right now.

When I use the scale tool on an image, I get that thing where I have to type in the pixels, but after I do that, and press Scale, I get the scale loading thing, but nothing happens, and the image remains the same size. It also doesn't work if I manually drag the image to size. It's only works when I type in the pixel width, then press enter, then Scale, but this makes the picture remain the same size. I also can't rely on this since I don't know the pixel size. This is what I hate about Gimp, either it's really glitchy or it's super complicated and I don't know how to fix something as simple as this. It's not the first problem I've had, and I have to close with saving, reopen everytime.

How can I scale an image without the image resulting to blurry edges?
What I want to do is simply scale my image in the same way when I zoom in it. Pixelation is not a problem.

just want to scale an image. I do File/Tools/Transform Tools/Scale. Then I adjust the numbers to my desire. If I reduce the size, there is blending that takes place amongst pixel colors.
Looks good except that the edges of the image are also being blended. Blended with what? The edge? I don't get it.
How do I scale an image, but leave the edges alone?

well - how to scale an image correct! I am pretty new to GIMP and i want to scale an image.
what is wanted: want to have an image with approx 300 x 200 pixel:
currently it (the image called Demo-image.jpg) has a size of approx 580 x 260 pixel.
First of all; i open a new window - (with 1080x540 pixel)
then i open my Demo-image.jpg in this newly created window - Question: should i drop in this Demo-image.jpg as a new layer or as a new picture. guess that this is pretty important. Unfortunatly i do not have any glue!?
Then i take the marker tool and mark the whole Demo-image.jpg - and afterward i choose (out of the toolbox -) the scaling-tool. Now i try to scale down the Demo-image.jpg.
If i am lucky then the scaling -dialogue pops up. Then i can see some values; height and width - What now happens is totally misterious: Whatever i do:
a. playing with the numbers (/height or width)
b. taking the demo-image.jpg with the "mouse" and tryin to scale "manually by shifting the edges...
All i do - it has no effect.

I recently upgraded to 2.8 and I like the interface changes a lot, but I have an issue with the brush slider's default scale of 0 to 1,000. For what I am doing, I would really prefer to set the scale more like 0-25. Is there a way to do this?

I'm looking to use script-fu to automate a process I do at work.
What I do is find images, paste them into GIMP, scale them down, and round the corners.
I've been playing around with script fu to make it automatically scale the image and round the corners, but I've run into problems with the image variable needing to be changed each time something is pasted.
Is there a way I can automate this, perhaps some code that will set the image variable to whatever the current window is, or am I stuck doing "manual labor"?

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.
