How to color overlay on non-transparent pixels only?

So I need help to make a layer that is a solid color that overlays over everything underneath it but only applies to non-transparent pixels. Is there any way to do this?

Well see, there's a lot of layers underneath it and the things that I want the color to be overlayed on changes often because I only want a few layers shown at a time.
Here, let me try to explain. I made a .psd file with a bunch of characters for a video game. All of the characters have the same body but different heads. I made layers for the body and all of the heads (the background is transparent.) The base layers of the heads and body is grey and then I created layers above them that were color and applied an overlay that was only as big as the head/body for every color. This quickly became tedius because of how many heads there were and I thought since the head and body are supposed to be the same color anyway I might as well created a layer that's a solid color above the heads and bodies that overlays everything. However, the problem is that color also covers the background and I only want the parts of the character to be colored.
Also, what kind of adjustment layer? Would that still be applicable in this situation?

Ctrl + click doesn't select ALL non-transparent pixels

Hello. 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.
Thank you.

I think it should. if your only going by the selection outline, then the selection outline only shows the pixels that are 50% or more selected.
In other words the pixels have varying degrees of transparency. If the selected pixel is not at least 50% opaque then the selection outline doesn't show them, but they are selected when ctrl clicking on a layer thumbnail.
After making the selection by ctrl clicking make a new layer and fill the selection with black and then turn off the visibilty of all the other layers.
You should get a better idea of what is happening.If you were to lock the transparency of the layer and fill with black you should get the same result.
If you use the magic wand at 0% tolerance then your not getting a true selection of the layer transparency, but rather making the partially transparent pixels fully opaque (selected).

How do i stop PS from deleting transparent Pixels on layers?

Hello community,
i have a problem concering the place-function of Photoshop CS6. I want to include hundreds of png files in a psd file and i want them to keep their original size. Unfortinatly they have transparent borders and PS deletes these borders when you place the images in the PSD-file. For example: I have a square with x=50px and y=50px and it is positioned in an png with the dimensions x=100px and y=100px. I want to have these kind of files in my psd-file an need to keep their full dimensions, because my graphic specifications relate to the 100px/100px size and i need it later in my workflow.
How do i stop PS from cutting off the tranparent borders of my images?

Yes Free Transform has what was set during the place and you can see in the option bar if the layer has been scaled or is at 100 % width and height. You can also drag out guide line to the transforms bounding box. Then later measure the size or drop in a low opacity pixel in two diagonal corners to force the bounds to the png's canvas size. However if you don't add those pixels in a script the bounds you get is that of the bounds of the non transparent pixels and in an action Ctrl|CMD clicking the layers content in the layers palette selects the non transparent pixels.
My Photoshop Photo Collage populating scripts do not always fill an image area when they resizing odd shaped png images, However if the png is rectangular with transparent borders the script will fill the area with pixel for the scripts gets the bounds of the non transparent pixels, not the png canvas size. So resizing works well. There is a difference between layer size and canvas size in the png file. Layers can also be larger then canvas size in psd files Photoshop support any size layer you have the canvas act like a cropping mask on a document.

Find bounds of contiguous transparent pixels

I have the need to find the largest rectangle of ONLY
transparent pixels in a transparent PNG. The transparent region is
non-rectangular, so getColorBoundsRect returns a rectangle that
also contains non-transparent pixels. Is there a way I can check
for a rectangle that contains only the color I set?

Barring finding a method to do this, I hacked together a
solution.
First, I found the bounds of all transparent pixels using
getColorBoundsRect.
Next I iterated from the top-down until I found the first
line with only transparent pixels to revise the top edge
Finally I iterated from the bottom-up until finding the
bottom line of only transparent pixels to revise the bottom edge.
I was able to compensate like as such because I know that the
rectangle is not impeded from the sides at any point, otherwise I
would have had to find the left and right edges as well.
I feel like there should be an easier way (and also a less
processor-intensive way) to do this.

Color overlay on opaque pixels of transparant image

Hi everyone!
I'm having a little problem here... I have loaded a gif image (a bufferedimage) in my program and I would like to have a color overlay on it. However, the overlay should only reside on the opaque pixels and not on the transparant parts of the image.
I have looked for about an hour on this board to find the solution to my problem, but I haven't found anything useful. I did find the following, but it's not for a bufferedimage :(
int pixels[][] = grabPixels(sprite);
     // 2) Place the opaque pixels in a polygon
     Polygon poly = new Polygon();
     for (int y = 0; y < spriteH; y++) // y coordinate
          for (int x = 0; x < spriteW; x++) // x coordinate
               if (pixels[y][x] != TRANSPARENT) {
                    poly.addPoint(x,y);
     }This code creates a polygon with the opaque pixels of the image I think. Too bad it's not for a bufferedimage!
Thanks ahead!
Jens

Thanks, Randy. That's ingenious, but it doesn't seem to work very well, since the finished image looks like Frankenstein's monster, with half the guy's face looking one way and the other half another way. But ingenious.
I don't mind using the limit effect if that is the best way to deal with my little problem. Just trying to get a consensus on what to do, after I put a contract out on this shooter.
Thanks.

I want to delete all transparent pixels, how can I? CS6

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.
Thanks,
JB

Image have rectangular area they have a width and height boundaries as do layer. Not all of the rectangular area need to have content or be fully opaque, However the image boundary is a rectangle. Some file formats are like a Photoshop Background layer do not support empty area or even transparency so those file formats only contain image that are rectangles and have no transparency. Some file formats support transparency and empty areas so those images can be any shape and contain transparency still the image boundary is rectangular. Then there is the GIF file format an oddball format. It only supports 256 Colors. Pixels are mapped to one of the 256 colors selected for the image. If you want Transparency in a gif the number of colors is reduced by 1 to 255 the 256 color now indicate no content its not real transparency it just a no color pixel in other words off or no content.
So if you have areas that are 100% transparent there is nothing to delete the area is empty. If you have pixels that contain some transparency and you delete those pixels you delete details are you sure you want to delete all pixels that contain transparency? You will loose things like drop shadows

How do i change a color when doing color overlay?

I finally figured how to apply the color overlay and the first picture I did my son was wearing a coral shirt so I made the pic a B/W photo and wanted his shirt to pop with the color it was. So it actually worked but then I wanted to do another photo with the same idea but everything is this coral color I thought it new to make the shir that color since that is what it was. I thought that when I go to use the brusg it would pull the color of that item instead everything is coral. I didn't set it to that color and I can't figure out to change it.
Please help me. I paid a lot of money for this software and I haven't been able to do what I want.

Agree with Kirby, as always.
And I believe that the OP has changed the brushes to color overlay thinking that you need this change to erase the black and white.
Simply apply the B/W adjustment, click on the gear in the B/W brick and choose "brush black and white away." You do not have to change the brush to color overlay. That is there just to help you see where you've applied brush strokes.
Change from color overlay back to none.
Let us know how that works for you.
Also have a look at this section of the manual.

How do you eliminate transparent pixels caused by glare coming from a painting and still retain org.

How do you eliminate transparent pixels caused by glare from the sun coming off a painting and still retain orginal color and composition?

You'll need to post the image for us to give advice.
In general, the glare cannot be removed. You can clone over the glare, but the cloned areas will not be the original underlying painting. Depending on your image, acceptable solutions might be possible, as long as you are aware of what is actually being done.

How to edit transparency pixels in a FilterPlugin?

I want develop a fiter plugin of photoshop. while i am not clearly about some issues:
(1) how does the photoshop provide the transparency data ( blank data ) to me ?
in other words, i want obtain the "alpha" channel data, is this provided by the "inData" together with other channels?
(2) I want to change the pixel's transparency, means i want change totally transparent pixels into
opaque. how to do it ?
(3) in the pluginName.r file，there are 7 entries in FilterCaseInfo like following. is there anything i must pay special attention to?
FilterCaseInfo
    /* Flat data, no selection */
    inWhiteMat, outWhiteMat,
    doNotWriteOutsideSelection,
    filtersLayerMasks,
    worksWithBlankData,
    copySourceToDestination,
By the way, When i invoke a filter (i develop it 2 yeas ago) on the transparency document , photoshop gives a messagebox said it canot invoke the fiter because the selection area is totally empty.
if the area has both transparency and opaque pixels, then the plugin cause write access faled and made the photoshop crash , why does this happen, how to avoid it.
Thanks a lot.!

First off, don't confuse "alpha" with "transparency" they are different.
If I create a RGB document with one layer and call the Dissolve example I get the following bits of information in the FilterRecord:
planes = 4
imageMode = 3 // plugInModeRGBColor
filterCase = 4 // filterCaseEditableTransparencyNoSelection
inLayerPlanes = 3
inTransparencyMask = 1
plane 0 = red, 1 = green, 2 = blue, 3 = transparency
See DoFilter, the loop on the planes, and DissolveRectangle, the changing of the data on each plane, in the Dissolve.cpp example file.
Now flatten the document and create an alpha channel and select all channels via the channels panel. Selecing just the alpha channel or any one channel will have different results.
planes = 4
imageMode = 3 // plugInModeRGBColor
filterCase = 2 // filterCaseFlatImageWithSelection
inLayerPlanes = 0
inTransparencyMask = 0
inNonLayerPlanes = 4
There is some documentation about FilterCaseInfo in the Plug-in Resource Guide.pdf found in the documentation folder.

How to create a view on a Non-Transparent Tables.

Hi,
i want to create a view on P0001 & P0002 tables.
these two tables are non transparent.
Can any body help me ,
Thanks in Advance,

Vinay

Hi Vinay
It seems you program HR-ABAP. Generally it is not required to create views since we use LDB (Logical database) utilizations in our programs. Doesn't it satisfy your requirement? Or is it required at somewhere you do not use LDB?

How to transition two pictures to a color overlay?

I want to transform the original pngs (the two characters) into a white color overlay as if it were filling with liquid.
video example using liquid transition (cc jaws): FREE 2D Intro Template - After Effects - YouTube

Thanks for the reply. I linked a video of the free template to show you the kind of liquid transition I want over the characters, I have no use for the actual template...
Mylenium I'm having trouble animating a color mask over the characters using a liquid effect, as if they were filling with the white color layer.

Changing JPG background to none/transparent.

I just switched from Quark 7 to Indesign CS5. In quark,the background color of black and white jpg could be changed to "none." This made the white background transparent. When 'none" is selected in Indesgn the white background remains white. Can a background color be changed to transparent in Indesign and how do you do it? Thanks

Blend mode set to multiply did an ok job. The problem is multiply makes the foreground color transparent and it is especially obvious when any other color is choosen other than black. In Quark the foreground color remained solid.
I work for a newspaper and do use tiffs with transparent backgrounds, but I use black and white jpegs when I don't want to go in and spend time removing a background in Photoshop. I can also change the foreground color without editing the actual image file. I never had any issues when it was printed.
Thanks for your help.

That is LIGHT LEAKS that you typically see on film. The only place I have seen anything like that is www.artbeats.com with a set called FILM EFFECTS.
Not cheap. $500 a disk I believe. SD only.
SHINE and TRAPCODE do that too?

Differentiate empty and non-empty pixels

I'm a web developer currently slicing an illustrator file for web graphics. Some of the icons and images have shadows, lights, etc, and it's impossible to simply see by a naked eye which pixels contains some shade or nearly transparent color and which doesn't.
It would be extremely useful if I could somehow easily differentiate between empty and non-empty pixels, so I wouldn't miss any when slicing.
Any advices??

Select the objects you want to cut, pick the artboard tool, and from its presets menu on the control bar choose Fit to Selected Art. In Safe for Web and Devices window, in the Image Size tab, make sure Clip to Artboard is checked. This will cut the image without including any empty (fully transparent) pixels.
edit: Alternatively if you hide unselected art (Shift+Ctrl+Alt+3), in the Safe for Web and Devices with the Clip to Artboard unchecked will cut the selected object/s without including fully transparent pixels. So with this approach you don't have to use artboards.
You can create new artboards for each icon, element, etc, by drawing with the Artboard tool and holding Shift. With the desired objects selected, draw a new artboard anywhere on the document with any size and choose Fit to Selected Art.
You can also see the bounding box that includes all pixels of the selected object/s while the selection tool (black pointer) is the current tool if you the Use Prevew Bounds option is on. This option is available in the General section of the Preferences and also from the flyout menu of the Align panel.

Increase opacity of semi-transparent pixels

Using the eraser tool or several other methods I can set pixels in a layer to be semi-transparent. Let's say I save such a layer without history. How do I make these pixels 100% opaque again? Is there some tool that does the opposite of the eraser?

Cross_ wrote:
That's very odd. Given all the ways to make things transparent I thought there would be just as many options of making them opaque.
Let's take another example: say I handpainted a layermask which has some 50% grey regions that should have been fully opaque. I then apply the mask to the layer. There is no way to bring those 50% sections back to non-transparent without repainting the image?
that's because (as others are explaining as well) while there may be several ways to do something, there are in some cases good ways, better ways, and bad ways. in general, it's better to work in a nondestructive manner, using adjustments and masks for example, instead of applying filters and using the eraser.
and as buko says always work on a copy.even if you just keep a copy in a duplicate, hidden layer in your document. you never know when you'll need to go back. it only took once or twice screwing up the perfect picture before i learned that lesson!
