GIMP :: Change All Pixels Not The Background To One Color

Oct 25, 2012

I have an image with an transparent background. I want to change all pixels that are not the background to one color. How do I do this? I can't select the pixels, they as arbitrariliy distibuted. I've played with threshold, but that's not working either. I tried Image-->Mode -> Indexed and then Use black and white palette, but that doesn't work either. I thought i would convert all non-transparent values to black, but instead its picking some threshold and making some black and others transparent. Example file attached.

GIMP :: How To See Color Palette To Change Foreground And Background Color

May 22, 2013

How I choose a color for any new objects I want to create. I've opened the toolbox with ctrl-b, which appears on the left side of the window. If I want to , for example, draw a red rectangle, I use the rectangular selection tool, then the bucket fill, and I don't see how to change the foreground color to red.

I've read elsewhere in the forum that there should be two rectangles somewhere on the screen that show foreground and background color, but I don't see them anywhere.

GIMP :: How To Remove Stray Pixels On White Background

Nov 3, 2013

I rebuilt my line on white background from Rich2005 and Ofnuts. My latest version is darker, smoother higher res and wider (see attached).

The problem now are stray pixels, many of them unattached to the line itself. I spent a lot of time with an eraser, but still haven't gotten them all. THERE MUST BE A BETTER WAY!

I found this excellent link on the subject. [URL] RobA even has a script to do what I want. However, I don't think it is GIMP 2.8 compatible, as I can't seem to find it to run it.

GIMP :: Change All Pixels Of One Value To A Different Value

May 29, 2012

I have a diagram scanned in one pixel mode (b&w). I want to change the line color from black to blue.

I tried this:

In the toolbox I altered the foreground color to blue. In the 'Select' menu I used the 'By color' option. I made sure the settings in the toolbox for 'Select by color' were set at default, then I clicked on a black pixel in the image. The black lines in the image became outlined with a dotted line. I then used the 'Fill with FG color' option from the edit menu. The sample color to the left of the menu item was blue. The image briefly 'repainted'. I removed the selection using 'Select' 'None' but the image lines remain black.

GIMP :: Color To Alpha Leaves Some Pixels

Sep 13, 2012

I had a .JPEG of a leaf photographed against a white background. When I went to turn that white background into a transparent alpha channel, it seemed to work okay....except for the fact that when I then went to select the new alpha channel via the Fuzzy Select Tool, it wasn't selecting all these newly transparent pixels.

GIMP :: Controlling Color Of Transparent Pixels?

Jun 30, 2012

How can I control the color of transparent pixels?

I save my image in RGBA (Windows bitmap). The RGB value of the completely transparent areas always turn completely black, and I want to control the color myself.

It may seem pointless, as the color is transparent, but I am using the image elsewhere (for creating mipmaps) where there is interpolation between pixels. Interpolating between 0 and 1 in opacity gives 50%, but the RGB part of the interpolation will mix with black, giving a dark halo.

GIMP :: Using Select Color Tool On Pixels With Transparency

Mar 28, 2012

I was using Paint.net but I've found it too limited. The GIMP has much more power and I can do a lot more with it, but I've found a few things I can't figure out how to do.

For example, when I use the Eyedropper tool () to choose a color, GIMP doesn't seem to include any transparency in the selection:

The Colorpicker just chooses the color at 100% opacity. Is there any way to change this so that my new foreground color includes the transparency level?

GIMP :: Color After Bucket Fill Is Not Solid / Some Pixels Remain Translucent

Mar 31, 2012

step 1) I remove the background of my image with the color to alpha method, isolating the part of the image i want.

step 2) I then use color select tool to select all the transparent area that was left behind from step 1.

step 3) I create a new layer.

step 4) Then I use the bucket fill tool to fill in the area on the 2nd layer that was selected in step 2.

This is where I run into trouble. On some pixels where the color filling meets dotted line area (made by color select tool) the color comes out translucent. I don't want this to happen. I want it to be solid ff00ff (color hex) without the random reductions in opacity.

I'm working with sprites and the emulator i use has ff00ff as transparent. I'm getting random pink color coming out of the edges of my sprites. These little specks of pink should not be appearing in game because it is supposed to be read as transparent. i suspect that these specks coming out are related to these translucent hiccups made in gimp.

Using VS9 (I know I need to upgrade.) I'm making a video to be shown on a 16x9 screen and have selected the 16x9 format. I have many 4x3 videos and pictures. In my original "preferences" I selected Blue as the Background color, added about 100 video clips and still pictures that now have blue on both the right and left edges of the screen. Is there a simple way to change this to grey or do I need to start over?

AutoCAD LT :: Change Background Color

Oct 14, 2013

Currently in AutoCAD LT 2013, was in 2000. In 2000 I had a drop down menu where I could change the background color. I used it to change the background to white before printing. In this forum I found out how to select monochrome in the print menu and haven't needed to change the background... till now.

When I print to my copier or to PDF the background is white like I wish. Then when I copy from PDF and paste to Word, the image is hazy. If I copy and paste to Paint, the background is black. The most important thing I wish to figure out is how it may be possible to transfer an image from my drawing to the manual I'm building in Word without it being hazy or black background, but I would also like to find how to change the background color.

Photoshop :: Can't Change Background Color

Apr 1, 2004

The area of the screen outside of the editing area of Image Ready used to be a light gray color. This would make it easy for me to see where the editing area ends because there would be a black line then the non-editing area space begins. Now it is all black and I don't know how to change it.
