GIMP :: Filling A Grid With Custom Colors?
Jun 6, 2013
I'm working on a project for work and I just started to play with GIMP for real after knowing about it for a few years.
Basically what I would like to do is take a background image, put a grid on it, and fill the squares in the grid with custom (not random) colors. Every spot on the grid will have a fill color.
I was thinking that I would use Excel to create a comma delimited file with each cell containing the correct color, and I want to know if there's a way for GIMP to read a hex value, color the square of the grid corresponding to the hex value, then move on to the next square.

After filling the inside of a line drawing, (cartoon "shape"), I'm left with the checkerboard pattern that indicates transparency. I'd just like to get rid of that checkerboard pattern so I can view my drawing the way it really looks! Can this be done in GIMP?

I am currently working on making a lens profile and the instructions are pretty annoying as they require the calibration chart to remain in the same spot while you tilt the camera as well as move the camera around to make sure that you are tilting the camera to bring the calibration chart close to a side of the frame but not clipping it and also staying within an angle of 10-30 degrees.
This seems overcomplicated, instead, why cant adobe make a single calibration grid where the camera is positioned in such a way that it fills the entire frame as much as possible without clipping, then it simply corrects using the single chart.
With the way it is now, unless you have the camera on a computer controlled dolly and computer controlled head, you will not be able to make a completely accurate lens profile.

I was thinking of something like photoshop can do. Have like a 32x32 pixel grid, then within that 32x32 square a 1x1 pixel grid show up? Of course a different lin maybe dotted?

I tried to get into the IRC to ask this question but I kept getting a 404 message. My question is....is "filling with transparent" the same as "tinting"? (explanation: In the image editor that Photobucket used to have I could change the color of something in a picture without losing the original shading, etc. They no longer have that image editor so I am looking for an Open Source program that is easy to use and has that feature.)

I was just starting to experiment with the gradient tool last week. I could have a circle as the selection, use the gradient, and then it would make the gradient within my circle all nice.But now whenever I try to use the tool, it fills my entire layer with the gradient instead.I know I still have the circle selected.

I've been working with this tutorial to modify some images. Link
I am unsure how to do one particular step however. Under 'Step 2', it reads:
"Next add a new layer to the image, and use the bucket to fill it with your tileable noise."
I can activate the bucket tool, but what am I doing with it?

I'm trying to change the color palette of a sprite's gif in GIMP, but I can't get the bucket tool to put the right color in to each layer.
Here's a screenshot of the gif opened up in GIMP with only the first frame visible.
Next, I selected one of the colors in the frame.
Then, I clicked on the new foreground color and set the blue and green sliders to 0.
Then, I selected the Select By Color tool, and selected the area with the old color.
Last, I used the Bucket Fill tool (making sure that FG color fill and Fill whole selection were chosen on the left) to add the new color, but I got a completely different color in its place.

I develop simplistic UIs using Paint.NET and I have a small overlay that is useful drawing them. I put the overlay as my second layer, but when saving it always prompts me whether I want to combine the layers or not. Is there a way to make the overlay a static non-layer grid image?

New to GIMP and would like to add some color to a line drawing. I have a line drawing that I scanned into the computer as a JPG. I've imported that JPG into GIMP.
the line drawing has a dozen or so areas created by the intersecting lines. I would like to fill the various areas with different colors. How can I do that?
If I pour a color paint on the picture without doing anything, the entire page changes to the color poured. Not what I want to do. I want area A to be red, area B to be blue, and area C to be yellow.

I have a cartoon line drawing. The black outlines are anti aliased so the edges of the lines have different grades of gray pixels on them. When I use the fill tool, and adjust the fill with the opacity and tolerance sliders, (I think that's what they're called in GIMP), I still can't get what I want. Only some of the gray pixels are colored in. Others are canceled out. Completely covered by the color, erasing some of the line.
Or some pixels remain uncolored. Just gray instead of a combination of the gray AND the fill color. What I'm looking for is an effect that looks like I placed a colored gel shaped like the cartoon character over the drawing. All the different shades of gray pixels should still be seen. Even the ones that are lighter than the fill color. With a gel, those pixels would appear darker, even though they were lighter than the fill color without the gel over them. The darkness of the color PLUS the added darkness of even the lightest gray pixels should make all the pixels appear darker. And the line would appear complete. Not partially erased.
Is it at all possible to get this effect?

I notice as I zoom in and out of the 3D modeling space that the background and grid colors fade from light to dark.
Is there a way to control the fading when zooming to keep the background and grid from becoming too light and illegible ?

I have been using Gimp for awhile (love it!) and have always used layer masks with no problems. But for some reason when I create a layer mask by filling in an area with black it isn't 100% opacity. Everything seems to show 100% opacity, but I can see the layers underneath (the mask is maybe at 90%??). If I "show layer mask" it is black where it should be and white where it should be, it doesn't look transparent. All my layers are set to "normal" mode. I'm at a lost as to what setting I must have changed?

How can I use the bucket-fill option to fill an area surrounded by a dottedline?
The dotted line is a path; so if I use a line for the dots, the bucket-fillworks.
But how can I step back after filling to change the path's line into dotsagain?

My image is in grayscale though it's recognised as RGB. It contains structures in white which I would like to fill with a colour. So basically, I'd like for all the white in the image to show up as e.g. red.
How do I do that? I'm guessing it must be possible to have a red layer and somehow this will then fill the white, but I'm getting confused with background and foreground filling options and I don't know which transparency options I have to choose.

I want to detect percentages of my artist's oil colors in any area of a vectorized photo that I point to.
So, I want to first vectorize a photo to reduce it to manageable separate color areas. Then, I want to be able to get a list of the various percentages of 108 different colors that make up any of the vector color shapes I point to or select. These 108 different colors are somewhat accurate small bitmap swatches that correspond to 108 artist's oil paint colors.
Alternatively, can I just somehow plug in this 108 swatch palette and have a software (Xara?) break down a bitmap into areas of vector color using only this custom palette?
Is this possible in Xara, or by any other means you know of?

I am trying to create a script that adds custom spot colours to the swatch pallet. I've manage to put together something that works (I've adapted an existing script), but the colours added are not spots, just CMYK colour swatches.Also, I need the script not to error if the swatch already exists.
//Add Custom Swatches
var docRef = app.activeDocument;
function cmykColor(c, m, y, k) {
var newCMYK = new CMYKColor();
newCMYK.cyan = c;
newCMYK.magenta = m;
newCMYK.yellow = y;
newCMYK.black = k;
return newCMYK;
[code]....

While creating the company logo and branding in Illustrator, I've taken the CMYK values of our color palette and created custom CMYK spot swatches for each of our brand colors. This was for consistency, because a spot's color numbers do not shift as you move between Adobe apps or from CMYK to RGB docs.
My question is — is it OK to hand off a document that contains these CMYK spots to a printer for 4-color offset or digital printing? Will it mess with the colors or will they simply igore the "spot" status of the color and use the CMYK values behind it?

First, I have not grasped the extent yet of how the new appearance library works.. we don't get crazy with colors, reflections etc.. but we do have a handful of colors that we use on the machines we use.. so instead of using the default appearance library, i made a new appearance library. All this went well, but i periodically as i need them will add colors to it.. problem is that i'm obviously doing something wrong, because my colors don't always stay in there after i restart Inventor.. and yesterday, i can't seem to keep any of the colors i setup in there to stay.. all i want to do is copy specific colors from inventors appearance library.. drag them into mine, rename them, maybe tweak the color, and then they be there for next time.. why won't they stay?
The edit pencil will come up on my library.. i've done the release edit after i'm done.. everything works in this inventor session, but if i turn inventor off and back on again.. they are gone.. only thing i have thought of remaining is that 3 users on our network share the same design styles location so we all our using same stuff, so is the file inventor uses in design styles to save to read only or something, but i read that appearances aren't saved in design styles.. How to do this and the colors stay and populate through all the existing stuff.. I have got the colors to lock into my template ipt in the doc appearances.. and i've done the save to custom library thing.. works until i restart inventor..

I work all across the country with different architects and engineers on a contract basis. Typically I create a custom menu that reflects each clients colors, symbols, layering ect. But now I have just upgraded to Acad 2012 and don't know how to create a custom menu in 2012 for each client. Is it even possible? What I have found is the customize button but when I modify a command for a specific client it makes the same change for all clients, as all that I was doing was modifying a workspace, and only modifying the command. What I have done in the past is to take the Acad.mns and copy it and rename it client-name-Acad.mns and make the necessary changes that the clients standards required. Can I still do something like that?

We are have been using Inventor to draw wooden furniture for a couple years, and have a custom appearance library with several different finishes (using photos of actual finished pieces of wood). Every now and then a part (ipt) takes a notion to not change to the color we set it to, seemingly without ryhme or reason. This mostly occurs with mirrored parts, but occasionally a standard (not mirrored part) will do this as well.
We have done all the obvious things, and some not so obvious. The path to the photos and the library is added to the project, and I opened the Appearance Browser and checked to make sure appearance knows where to find its bmp file, and it still doesn't do it to change color. And yes, I tried restarting my computer, because a couple days ago I was working with the Appearance Browser, and sometimes restarting Inventor made a difference in whether certain things worked or didn't work. This is also not limited to one computer, it acts like this on all of our computers.
We are using some png files and some bmp picture files. Would the file format maybe have something to do with it ?

i dont what to calculate the right spacing on each grid cell as the grid filter gives me i just what GIMP to calculate me the right spacing for this image and grip line width.

I'm trying to use Gimp to add a visible grid to a printed picture, so thatI can use it as a guide when painting a copy of the pic. I haven't beenable to figure out how from the documentation. There is a grid, and itshows on screen, but not when I print.

I've been editing a whole lot of pictures lately for online listings. Suddenly ctrl-z is no longer my "undo" shortcut. When I use it now, I get "configure grid".
Clearly I've changed my shortcuts. I have no idea how. What I need to do is figure out how to fix it, so I can have ctrl-z be Undo again.

When I need to rotate an image a few degrees a grid is displayed over the image, as a guide. However, the grid also rotates, making it a somewhat useless feature.

One of the purposes I want to use GIMP for are in scaling the dimensions of objects like musical instruments or sculpture, to create a construction plan. If I have an undistorted photo of, say, a guitar, and I know at least one dimension in the photo, I can SHOW and CONFIGURE GRID to get a "1 square = 1 inch" reference and extrapolate the remainder of the dimensions.
What I need to be able to do is include the grid in a saved/rendered photo file, which GIMP doesn't seem to want to do. The grid appears to be virtual, and disappears when layers are flattened out and the image is exported.
Is there a way to do this, or do I need to generate a standalone grid as a transparent layer and include that in my merge? If so, how do I go about generating a grid layer without having to hand-draw one?
