I opened a transparent PNG and exported the PNG to another file and unchecked 'save color values from transparent pixels' but about 20% of the color values in transparent pixels STILL remain in the picture when viewed in other programs that show those pixels!!! Gimp is NOT removing ALL color values in transparent pixels!
View 1 RepliesHow 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 2.8.4 Windows 7 64-bit
Using the native GIMP rotate function to rotate a rectangular image about its center (for instance) the corners of the image which are exposed by the rotation are set to RGB 0x000000 with an alpha value of 0.so that these areas are transparent.
If the same operation is performed as a GEGL operation the corners have RGB values of 0x000000 but alpha values of 255 - i.e. they are solid black.
Is there a setting to cause GEGL to use alpha values of 0 for these pixels? This also applies to GEGL operations such as shear.
How can I convert all of the transparent (100% transparent) pixels in an image to a specific color?
Adding a color layer below is not the solution I'm looking for, because some pixels are partially transparent and I don't want to modify those ones.
I use the "select color range" feature alot to do things with specific color pixels, but that feature doesn't seem to work in this case.
I am creating bitmap images for a program, where the transparent parts of the image need to be represented by a specific color.
I have an image that has corners with partially transparent pixels. I would like to make a mouse-over image of this with the same same dimensions, only a different color.
How can I color this image a different color and still have the partially transparent pixels around the edge. Obviously, I would like the semi-transparent pixels to be semi-transparent of the new color.

I have been using Gimp for a lot of "tile based" images, which feature layers composed of several "tiles" pasted into those layers. However, I just recently started creating transparent tiles, and pasting them.
One of the strangest things I have run into here is that I don't seem to be able to move my selection ( Floating Layer? ) if the opacity on the source pixels is 0.25 or less. Specifically, I do not get the usual "drag box" when I hover over the transparent pixels. Instead, I get the "anchor box" ( which seems to crop the pasted area before anchoring ). I tried this on a composite image with some more transparent pixels ( 0.25 ) and some more opaque pixels ( 0.26 ), and the "drag box" appears only over the more opaque pixels.
Why this might be happening? It could be that this is just context-sensitive cursor behavior which varies on transparency, and if so, is there another way to move the pasted selection?
Whenever I have a selection in an image, I can move it around all I want and wherever I want until I anchor it, but when I open that same image again after saving it and then select a part of the image, I can't get my selection to move. Rather the entire image moves and leaves transparent pixels. How do I move selections and not whole images without leaving transparent pixels?

View 3 Replies View RelatedI 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.
View 4 Replies View RelatedI 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.
View 6 Replies View Related 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?
I have a plain rectangle with overall c09300c0 RGBA levels.I want to change the alpha channel value from c0 (193) to some other value, for the whole image at once. Or some other color channel.
How can I change the absolute value of a channel ? The color menu has only relative adjustments.
How can I find all pixels in an image with an exact, specific color? So far, I've only managed to find the pixels matching a pixel I click on; but I wish to find pixels matching a specific color value!
View 1 Replies View RelatedI have been using Photoshop for years with no problems. I had to reinstall it a couple of time due to my PC having problems. But this is the first time i have had this problem.
I open an image and it is transparent. All you see is the boarder. When i select the boarder you can see the image, but as soon as i click off the boarder it disappears.
This image shows that you can not see the picture, but there is a file and an image, as you can see the layer on the right with a picture in it.
This has never happened before, i assume that there is a setting to be changed, but i cannot find it.
Then GIMP starts its foreground and background colors aren't black and white anymore.
I would like to know how to reset them back to default values (then program starts).
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.
Basically, I was working on a drawing in GIMP, and the paintbrush tool would not work on a transparent layer. I had one layer under it, which was white and had my drawing. The brush would work on that layer, but not the transparent layer above it. I tried with my Wacom Tablet and my mouse pad and neither worked. What else was peculiar was that I could use the Pencil Tool on the transparent layer.

I'm using Illustrator CS6 on OSX Mountain Lion.
I have a portrait shot on a grey cloth background and I need to remove the grey background.
Replace color is useless, as is the magic wand.
However the BG is comprised of pixels that are all VERY close to neutral ie
Red -231
Green - 232
Blue - 231
etc
I am trying to find a way to select only those pixels that are within 1 or 2 from the other components, ie it would select for the above selection:
Red - 230-232
Green - 231-233
Blue - 230-232
2 days on GIMP. I need to adjust the clone tool so it's 1080 pixels vertical and about 20 pixels wide. I googled and searched, but I can't seem to find the right phrasing.

View 19 Replies View RelatedI have a jpeg image of a motorcycle on a pure yellow background. I want to make the yellow transparent. Naturally there are a lot of spaces within the motorcycle image that contain yellow.
I followed instructions I found...
Removing the background of an image
1) add an alpha channel to your layer
2) use colors/color to alpha and use the background color
This results in the checkerboard being applied to the motorcycle, not the yellow background. I assume that's okay.
This makes all the pixels with the background color transparent, and those with a close color partially transparent.
Then:
- select the background with the magic wand,
- grow the selection by a couple of pixels to ensure that the border of the sprite is in the selection (the most important work of color-to-alpha is on the border pixels, so they shouldn't be protected)
This selects only the area outside the bicycle, but I don't mind reselecting smaller areas, if I can.

How to change the color of an icon (ex: from black to grey). My problem is that the end result is sometimes an icon that is partially transparent.
Here is what I am doing:
1) I open the image of which I want to change the color (black icon over transparent background)
2) Create a new layer and color this in white.
3) Merge the two layers
4) Create a new layer and color this with the color I want for my icon
5) Go to Colors -> Color to Alpha
6) Select the current color of the icon
7) Click Ok - Now icon color is the wanted color over a white background
8) Create a new layer and leave this transparent
9) Go to Colors -> Color to Alpha
10) Select the white color (current background color).
11) Click Ok - Now icon background is transparent, but icon color is also partially transparent.
Is there a way how I can change the color of an icon without getting the icon color transparent.
as you can see I was able to make the background transparent by 'select by color' + 'add alpha channel' + 'remove selected area' but I also need to remove the white behind the 50% opaque reddish orange flames as well, i cannot select the white by 'select by color' or 'magic wand select' or any of the selection tools because of the issues of the white / reddish orange mix of opacity, so I need removing this white behind the part opacity color.

In optimizing a new assembly I'll often have several iterations where I take an assembly to a point and would like to keep that design intact, yet would like to move on from there with new design features based off that existing design.
Currently this is the way I archive these fully functional design iteration steps that may be created just a few weeks apart.
Open assembly - save as "LinkageDesign-7.iam"
Open each part individually - save as next part # sequence...
In the new assembly then RMB click on each part and replace with new part # sequence that I just saved.
Parts keep all their contraints and are ready for me to start adjusting, all the while having the other version still intact so I can compare directly 2nd iteration with 7th iteration.
A way to do this with fewer clicks? As the larger the assembly the larger the task at completing this.
I'm working on a fire damaged 4 floor condo project.I have an xref zip folder sent to me from the original architectural firm. It's been unzipped. Now I have multiple drawings. Each with it's own xref. I want to be able to have a fully editable drawing (in this case of a 3 story condo). I want to be able to add or delete, at will, any part of the drawing without any concerns of messing up an xref file.

exported transparent png fiiles get this rainbow of color distorted bleed when previewing or importing into programs that cannot read the png's transparency!!! even program that can read the png's transparency after you check a 'make transparent' checkbox (such as Memorex Expressit label design studio) have this distorted color bleed!! like in the label program checking 'make transparent' leaves the rainbow color distortion in!!!
this seems to be ONLY happening with Gimp exported PNGs!!! other PNGs and other programs that can generate transparent PNGs don't have this issue!
There seems to be tons of threads on how to make a transparent image, but I haven't been able to fine one to do one specific thing.
How do I set the alpha channel to be black? I want to have a black background on a png file, but I need the black to be transparent to things behind it on a webpage.
