This is probably really basic but... I'm a printer and only really use Photoshop for changing RGB to CMYK, clear cutting (with Vertus fluid mask) and things like that. However a lot of the photos I have to clear cut have been done already but not saved (or given to me to use) with the transparency still there. Is there some easy way to turn all the white pixels into transparency? Obviously you'd have to mask any white pixels in the image you wanted to keep. A sample is attached.
I have a JPG which is a black and white line drawing I want to drop this on a collage where the line drawing shows, but the background must be transparent so other things come through. Essentially, I want to turn the color [ or lack thereof] white to be transparent, and black to be black.
I didn't realized that as I'm importing images, the 'background' was defaulting to white. I'm working a couple images right now, in which the transparent setting is really needed. I found where to change the default, but not how to change it for existing images in PS already.
I have a multilayered psd file. All layers should remain opaque except the black to white gradient layer where I need the white to be transparent. So that when I place the final psd on top of a block of solid colour in Indesign the gradient shows the background colour through where the black fades off.
I would like to delete all transparent pixels surrounding my irregularly (non-square) image. The TRIM function only trims to a square surrounding my image and not to the edge of the image itself. Is there a work around for this? I have looked around and haven't found one.
I have an image (of many layers) which are mostly solid color, and solid alpha. 1-bit alpha, which is exactly what i want. However there are a few parts which are slightly blurry, where it fades between the two. this is causing problems in my end result. The common white halo effect.
I've tried the flaming pear solidify plugin, and it's totally not what i want. I don't want to fill everything with color or mess around with alpha channels. What i want to do is convert all partially transparent pixels, to either 0 or 100% alpha, with no middle ground. Essentially to make the image alpha binary. ideally some plugin which lets me define the threshold for one or the other would be nice.
I'm saving as an 8bit png, which naturally forces everything to be 1-bit alpha. this is unfortunately resulting in a lot of pixels being white where they show as almost invisible in Photoshop, so i want to fix this problem author side. Ideally i'd like to not mess around with alpha channels - i like the png format because i never have to touch the alpha channel, it's all done for me which speeds up workflow dramatically. I know i can save as a 24 bit png which will store the partial alpha information, but this also increases file size which is not an acceptable compromise for my purpose.
I'm interested in doing a non-destructive "resize" of an image, whereby only the transparent pixels are traditionally resized and the non-transparent pixels remain the same size (but move relative to the resized transparent pixels).
As an example, imagine an image that consists of stars on a transparent background. If we were to do the above to this image, the physical space taken up by the image would increase (due to the resizing of the transparent pixels), but the stars themselves would remain the same size. In short, the stars would appear to spread out to fill more space.
I have two layers and some of the pixels in each layer are the same. I want the difference on the pixels that are not the same and for the pixels that are the same I want the result to be a transparent pixel. I have tried using the difference blend node but for pixels that are the same it returns black as the result not transparent.
I'm making graphics for a 2D game. One important part of performance optimisation is getting rid of unnecessary alpha sorting. I don't want partial alpha unless i have a specific need for it. I'm wanting all my images to be 1-bit alpha only. That is, a pixel is either completely opaque, or completely transparent - never inbetween.
I'm not sure how to do this easily in photoshop. So far i've come up with a workflow that fills my needs pretty well, except that it seems unnecessarily long and complicated:
1. Place the graphic on a transparent background
2. Use the magic wand to select transparent space, using the tolerance value to define the cutoff point
3. Select Refine Edge, and shift the contrast up to 100. For some reason if I don't do this, photoshop will often "partially select" a pixel, giving undesired results.
4. Hit delete. This removes all pixels that were selected (transparent enough to fall within the tolerance)
5. Select > Inverse. Shifts my selection to everything except what i just delete, ie the actual graphic.
6. Using the color picker, i pick an appropriate neutral color from the main body of the graphic. or i use black.
7. Using the pencil tool, with the draw mode set to Behind, and with a colossal radius, i draw on the graphic. This fills in all the remaining partially transparent pixels with the solid colour that i chose
This workflow does the job perfectly for me, and exactly achieves my intended results. but i can only do it on one layer at a time (i usually need to do this on about 18 layers, for a character graphic).
So what i'm looking for here, is some way to automate this process. The overall point of it really is forcing all pixels to "take a side", becoming either fully transparent, or fully opaque. Is there any better built in way to accomplish this? or a plugin? I'm open to commercial tools and plugins, even.
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'm still not allowed to use the link vb, but let's try this: ....

whenever i copy and paste something into a new layer i have all these while pixels that where copied along because of the rectangular marking. is there any way to get rid of these pixels ending up with only the pixels that make the object i wanted to copy?
How can I select ALL non-transparent pixels from a layer?
- Ctrl + click doesn't work (it seems to have a 50% tolerance - my opacity 7% and 40% pixels don't get selected);
- The magic wand tool with 0% tolerance does work (when I click on a transparent pixel it selects ALL opacity 0% pixels around it and then I just have to inverse selection), BUT my image has a lot of holes with transparent areas and selecting them one by one would be tedious.
I'm not sure why, but Photoshop just started doing this after I converted my files to a smart object. When I try to zoom in past 50%, it displays these transparent pixel squares over the entire image. I tried rasterizing and flatting the image back, but that didn't do anything. It seems to keep doing this.
I have accidentally made my drawing in black and shades of black (grey) on a white background in Photoshop. Is there a way I can delete the white pixels only and then have only the grey and black pixels remaining? If possible, I don’t want a hard pixellated edge where the white and grey/black pixels meet.
What I want remaining is only the black and grey lines with a transparent background.
I need to know how to make these pixels in the picture go away. I tried making the background black but It makes it look ugly. Is thier an eaiser way to do this?
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.
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?
I need to create an outline map for another application. The world is demarcated into areas, separated by black lines. The map must only have black & white pixels.
Some questions about using GIMP for this.
1. Is there a tool I can use to make every non-white pixel black?
2. Is there a tool I can use to eliminate isolated pixels of the wrong color (that is for me a black pixel with all neighbors white or vice versa)?
3. Is there a tool I can use to make the black lines thinner? It is desirable in my application to have the lines be only 1 pixel wide
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.
