GIMP :: How To Get Average Color Within Selection Island
Apr 21, 2010
Let's say a have an image mask (see image shown below) where the white areas are the selection islands and then apply that to an image. What I want to do is get the average color for each selection island in that object. Just blurring gives you a gradient effect and if you blur too big, you just get a single color. That's not what I want.

I have some paths covering several shapes (Islands, to be precisely), and they've been merged into a path file and bounced over a few documents. I'd like to select the path for just one of those islands so I can move and scale it. Is there anyway to separate one closed path for the others in the same merged file?

I am taking daily shots of a fig tree which is just in front of my kitchen window. At the end I would like to produce a video showing the fig tree blossoming and then loosing its leaves. I am realizing that the lighting is changing from one picture to the other. Is there a way to even out the lighting of all my pictures to a given average?

Is there a way to select a portion of an image and display the average RGB or Lab values of that area? Right now I can only see the values of selected individual pixels. Instead of manually adding up these values to get the average value which is quite tedious, can someone help me to a better option?

I need to analyze an image and read the value of each pixel, exclude the highest and lowest values (perhaps anything less than 10,10,10 and greater than 245,245,245) , then average the remaining. I may need to do this on each channel of RGB.
I can almost get a result blurring the sample and then using a large brush with the info tool, but is there any other method more direct and all inclusive?

Is there a way to change an object's fill from a gradient to a solid color that is the average of that gradient? What I want to do is have a grid of squares, select them all and apply a colorful gradient to them as a whole, and then average each square's color so I end up with a pixelated look. Kind of like the mosaic filter in Photoshop, but in vector.

i would like to fill a selection exactly with a defined color (full red). I want everything inside the selection to be full red and everything outside to be untouched but I don't managed to do it.
With the bucket, even in normal mode with opacity 100, "fill whole selection", there are still pixels outside the selections that become half red. With the pencil, same story.

In the image below I have an aerial photo of an Island. I need to make it so as water areas are black and land areas are white (not greyscale) almost like a silhouette. My first plan was to draw round the island with a black paint brush and then use the "bucket fill" with a suitable threshold to fill all of the areas up to the black outline with black, however this doesn't work as the bucket fill either breaks through the black line or when I reduce the threshold, doesn't color the water areas solidly.

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 am a new user to paint.net, because the tool I used for complex image manipulation does not run on the OS of my new machine. Although I could easily purchase the newest version, I needed work on some pictures now. Paint.net was easily available and does most of the thins I need at the moment. In addition, it is officially supported at my work place, so it's a good idea to learn how to use it.
Paint.net has some great features and a cute UI, but there are some issues I would like to see improved. The one at the top of my list is the font preview. I am doing some text on a number of pictures and want to check out some fonts. Unfortunately I can't change the sample text in the font list (at least I do not know how).
However, meanwhile I found a even better function (actually the way I would like to see it). When the font list is open, I can scroll through the list and the text will instantly updated. Cool.
Great thing would be to move the color picker out from the tool box into the color selection, so that it would be always available. Also it would be useful to not only pick one pixel sometimes but the average of a greater area.

Working in Illustrator CS5 on a Mac. When choosing a color in the palette, the preview showing up is different than what is in the palette. If I hit "OK" the actual color chosen is the one in the palette, not the preview window... Including some pics for reference. In my 10+ years of using Illustrator, i have never seen this.I am using a Dell monitor on a mac... not sure if that would make a difference.

Somehow I've turned off the color selection so that I don't have a color when I select a part of a drawing on a layer. The drawing area stays black whether I have selected it or not and I don't know how to turn back on the color.
how I can turn on the color again so that when I select a line it changes from black to red or magenta or whatever?

I am looking to draw a large lake that I live on that has 14,000+ islands. I have started drawing small sections by bringing in high quality maps and tracing them using the spline command. Is there a faster way to trace the entire lake.
I want it to be all drawn with closed poly lines so that I am able to laser cut it and apply hatching. Other tracing programs in which I insert a image of the lake and it gives me the CAD format are very inaccurate and a pain to work with.

I opened up a drawing which had a hatch over an area, and after deleting some text from within the hatch extents, found that the hatch didn't ignore the text & put the hatch behind it, rather, it created an island around the text to avoid a hatch/text clash.
I've removed a few pieces of such texts, and now have a bunch of rectangular holes in my hatch where the texts used to be. How can I remove these islands completely without having to re hatch the whole thing again?
(I realize I could simply minimize the size of the island by picking the four corners/vertices of the hatch and bringing them closer together, but this is a messy solution)

I'm drawing a map of an island and I want to have the colour blue surrounding the island representing the sea. But I want the blue to gradually fade into nothing. I've tried to use the sray can but its just doing weird things with rectangles!

I am using AutoCAD Map 3D 2013 version. While using SuperHatch (with Block option) in island polygons, the command creates 2 extra lines. see the attached screenshot. The 2 yellow color lines are extra lines.
Is there any option or setvar to switch off these 2 lines or control this behaviour ?

I am trying to create an Island family with cabinet components nested into the island family. I have included both a 3D view of what I want the island to look like and a floor plan of what I have right now. I want to be able to adjust the size of each of these cabinets with a parameter. But I am not sure how to get them to stay lined up like they are right now.
If I change the size to a larger size the center cabinet overlaps the cabinet on the right. but if I add another reference plane to the right side of the center cabinet, when I try to adjust the size I get an error message saying "Constraints are not satisfied".

I am comparing multiple scanned images and I need to find out if one image is darker than another. For example, if you print a document on 5 different printers and then scan those documents into photoshop 7, is there a way to quantitatively analyze how dark each document is. Can photoshop 7 tell you the average darkness of a selected area of an image? They will all be scanned on the same scanner so the only variable should be the printers. I need a numerical value for each, not just a visual comparison.
I am using Windows XP and photoshop 7.

I have 10 layers and I want to blend them such that the resultant flattened image represents the average colour. i.e. If layer 1 has a white pixel and layers 2-10 have black pixels the result will be 90% black.

As the title points out I need to find an average of the L, a, b values from a region of a photo. I can find out the values for a single pixel but these values vary to some degree in the region I am interested in. If this can not be done in photoshop but in an other program i'd be if you could show me how.
