GIMP :: Area Image Selection Transfer To Image Map Polygon
Nov 27, 2013
The problem is that if one has defined a selected area in an image, using either selection by color or contiguous selection using the 'magic wand' facility, is possible to copy this selection to the Image Map facility of the image, so as to automatically define a set of coordinates as a polygon that can be used for link purposes? Perhaps there is some interim step that is required, or perhaps a special script is required?

I want to select part of an image with just one layer. Say I just flattened the image and have to move one part of. I select it with the rectangular select tool. It seems intuitive that I could then just move what I selected, but when I drag the selection, the selection itself moves without moving what is inside the selection.
If I then remember to click the move tool and try to move what's in the selection (seems to work sometimes, maybe when there's multiple layers?) the entire image moves.
The only way I can move part of the image over is if I make a selection and then cut it (ctrl X) then paste it.
How am I supposed to move part of the flattened image, is there a way I can set it to default to "When I select something, I can immediately drag that selected area around."

I want to remove all but a rectangular area from an image. I do not want to make the rest of the image white, I want it to go away. I want to just have the rectangular image pixels left.
To be explicit, I want it to be like I cut up a photo, and threw the outside away.

I've tried using GIMP many times, yet I've accomplished very little, given all of GIMP's functionality. For example:
If I want to select part of an image and copy it to another area or to a new image/layer, and also FEATHER the edges, here's how I'd do it in an old graphics app I often used years ago:
1. Select the area.2. Hold Ctrl while moving selection with Move tool.3. Use the slider to soften the edges to my liking.4. Press Enter to anchor selection. Done.
And there were sliders also for opacity and other things. So very SIMPLE because the prog. was designed very intuitively. How would I accomplish the same in GIMP? Well, most of the time, I WOULD ACCOMPLISH NOTHING! At best, I'd enter values into the box, not like the result, enter new values, repeat. And that's on a good day.
Somebody write a SCRIPT/PLUGIN that allows the use of sliders exactly as described above! I desperately want to be a HAPPY GIMP user, but I'm growing ever more hopeless. I don't want to turn on my older PC just to use a graphics app that actually lets me get things done.

Some time ago, the Gimp stopped responding to my mouse in the image window. In other windows and on menus the mouse works fine (ie I can select brushes and such and use the interface without problems), but in the image window (or more precisely, the canvas area) it's as if the mouse doesn't even exist. All kinds of clicks are ignored, the rulers doesn't show the position of the cursor, and the position in the lower left also isn't updated (it isset once upon entering the window, but after that it's dead).
This originally happened out of the blue one day while using Gimp 2.2.11 . I tried upgrading to 2.2.12 and then 2.3.13, without success. I also deleted the ~/.gimp*directory in the hope that regenerating the config would fix the problem, but no.
No matter what I do, I can't make the Gimp recognize the mouse in the image window. The mouse isn't anything special, and it used to work with the exact same X config I've got now. I haven't changed the xorg.conf file in several months. The Gimp is the only application with this problem.
This is on a dual-core amd64 processor in 64-bit mode (haven't tried 32-bit), Linux kernel 2.6.18, Xorg 7.1.

I need to add a border to an irregular object. I want to add a simple line around an object, with about 5 pixel space between the line and the object. How would I do this? Basically, I want to achieve an effect like the image below with the lines around the border of the land at the sea.

I'm a former Photoshop user. The reason I no longer use it is because of a silly misunderstanding with the NSA and MI6. But hey, that's the past and I'm a believer in moving on.
Anyway, my first inquiry here is a simple one having to do with selection. When I used PS I would at times use the wand selector and then open a new file which already had the dimensions of the selection. Thing is, when I select something in Gimp and open up the new file it still has the same size as the main image from which an area was selected, i.e., if the main image was 500x500 and I selected something 100x100 the copy was still 500x500.
And I can assure you it has nothing to do with remote viewing and foreign embassies.

I need to assemble multiple images in an illustration program (inkscape or illustrator for example). So I want to cut and paste several regions from different images, but I want them to all be exactly the same size. What I had been doing in photoshop was just dragging the selection from one open image to the other and that would preserve the size so I could copy again, but that doesn't seem to work in GIMP, or rather, nothing I tried seems to work.
How can I get a selection to be identically sized between different images without actually moving any part of the image itself?

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

I want to crop several images in same aspect ratio.So I checked "Fixed" option and set proper values in tool box.
And sometimes I want to complement image with background color if selectionis larger than original size. In this case, I add a larger layer bottom of the image and crop it.
But it would better if I can do it by one action.Therefore I'm trying to write a script-fu for it, but I'm stuck now.
Because a function `gimp-selection-bounds` returns points only inside ofthe image even if the selection is outside of image.
Is there a way to get bounds of selection outside of a image by usingscript-fu?

I made a complicated selection, which I saved to a channel. Then I inverted the selection and tried to delete the inverse (hopefully to transparency, but deleting to a background color would be better than not deleting at all). However, nothing happens when I press the delete key, or when I select "Clear" from the edit menu. Trying to use the Cut command doesn't work, either.
After deselecting, I can get the selection back through the channels dock, by right-clicking and then choosing "Channel to selection" or "Add to selection." It appear to replace the selection from the channel properly. I just can't delete anything.

you've zoomed in to start this painstaking freehand selection withlots and lots of points, and when you get to the end, nothing getsselected. Then you notice that, once again, you had done a Select Allsome time ago (invisible because you zoomed in) and forgotten to SelectNone before clicking the lasso.
What do people do to avoid this? (I know the obvious answer is "rememberto check what your selection is all the time", but that's seriouslyflow-disruptive.)
GIMP could blink the image or something when you add selectionpoints that don't increase/decrease the already selected area, but Iguess that might take some time to implement.

When I use the Fuzzy select tool or the select by colour tool, how can I remove the selection area around the parts that I don't want selected. For example. I have red car on a white background which I want to cut and paste to a black background. I select the white background, but although it selects all the white, it also selects other small areas on the car which are a similar colour. If the threshold is lowered too much when I use these select tools then I get a very small white border around the object when I paste it on to a dark surface. So instead of selecting using the default (15) or even less, I have to ramp it up so as the selection is closer to object and does not show the white jagged line. I thought that I could use the other selection tools with the "remove from selected" option selected, but each time I place a rectangle around the selected area that I want ot deselect, it does away with the entire selection area. I just cannot get it sussed.

I want to copy one image and paste it into a selection (masked) of another image. I have the option to paste into which works but would like to be able to paste in Place as I believe this makes it a smart object and references the original file.

How do I combine a fuzzy selection area with a dodge or burn operation?
The fuzzy select tool is handy for roughly outlining areas of over or under exposure. There must be a way to combine an oddly-shaped fuzzy selection area with a jittery dodging operation. Do I have to turn the fuzzy selection area into a "brush" somehow, in order to "dodge or burn" that area?

When I am in an image, selecting an area with the polygon lasso tool, every time I click a point, the image blanks out and does not redraw. I am left with my pologon selection lines and a white image where the photo should be. The only way to get the image back is to force it to scroll. I have to extend the tool off one side of the image or another to make it scroll. Otherwise the screen does not redraw. I am forced to work with my images in a window instead of fullscreen to ensure that I have part of the image to scroll to when the image blanks out. It is doing this with every click of the polygon lasso tool. Needless to say, this is maddening! Has anyone seen this behavior before? I am running Adobe Photoshop CS3 on Windows XP and the program is up to date. I have two gigs of ram and have moved up the memory allocated to Photoshop from half to two thirds. I have stopped having other programs opened. I also tried turning off the preference for the 3D graphics acceleration. So far nothing has worked to fix the problem. I have about 1100 product photos to clip out -

Goal of the task : I need the area of different type of soil. I have an image of these different soil, but I need to create a polygon manualy for each and every one of these. This is to calculate the runoff coefficient of a watershed.Â
As they are different by their colors (blue = lake, green = forest, etc), I would like to know if it is possible to convert these image to have an polygon usable in autocad, where I can calculate the area of each type of cover.Â

I am making a video in Nero Vision 10 and need to cut out the screen of a tv so that I can layer the TV over an image/video so it looks as though it is on the screen. I enclose a screenshot of the project. 'Transform-tools-crop' only cuts in straight lines so I wonder which device I should use which can cut out an odd bespoke shape? You can see in the uploaded image from the project how the image currently cannot fill the frame without covering it.

I have a PNG image with only one layer as a start point. It has a faded map on it.
I have a second PNG image with a hex grid on it. I do colour to Alpha to establish transparency on the hex grid for white filled hexes (others are not filled with white).
Now, I wish to overlay a portion of the first image with the faded map with the non-transparent part of the second image.
So I select by colour (for the hexes not filled with white) on the second image (the overlay) and I then paste to the first image (after creating a transparency layer and selecting it to receive the overlay).
I see the desired overlay section (minus any transparent stuff as expected), however it is centered over the map in the first image, not where I want it to be. It is a floating selection and must be anchored. So I select the anchor icon in the layer dialog and I think I anchor it into the transparency layer on the first image (that's what I'm trying to do anyway).
And then my problem:
I want to move the thing I just pasted in to the right place with respect to the underlying faded map. I attempt to use the move tool, but all I move is the background map (pretty much the opposite of what I want).
Nothing I do seems to let me reselect the pasted-in overlay so that I can move it.
Why I can't ever reposition the pasted in overlay? It should be in the transparency layer I created but even if I select all, I don't seem to be able to move anything other than the background image.

I'm running Gimp 2.8.4 on Ubuntu 13.04 Linux (64-bit) and I'm trying touse the "Bevel and Emboss" layer effect on an image which I copied fromanother image. Here is what I've done:
1. Loaded image 'A' into Gimp
2. Selected a portion of it
3. Used "/Edit/Copy" to copy the selection
4. Used "/Edit/Paste As/New image" to create a new image from the selection
5. In the new window for the new image, "/FX-Foundry/Layer effects/Bevel and Emboss"
6. When the "Bevel and Emboss" window opens, I accept the defaults and click "Ok"
The filter starts to run and then stops with an error message. Here is the message I get:
------------ START ------------------
Bevel and Emboss Message
Error while executing script-fu-layer-effects-bevel-and-emboss:
Error: ( : 1) Procedure execution of gimp-selection-layer-alpha failed on invalid input arguments: Item 'Pasted Layer copy' (87) cannot be used because it has not been added to an image

I have been using gimp now for about 2 months and have just upgraded my OS to Mavericks and upgraded Gimp to 2.8.8.
Upon doing this I seem to have lost the ability to copy/cut an image or part thereof from one open image into another... Example:
I have an image window open with a picture a car and I have an image window open with a race track back ground.
I want to copy the car from image 1 into image 2, but for some reason I cannot do this function anymore. When attempting it, once the item is copies to the clipboard and I then swap to the second image, when I paste as a new layer it pastes the clipboard from that image and not the image from the first window...
