Photoshop :: Revealing Hidden Color Pixels In PNG?
Jun 28, 2013
When I open this image in Photoshop the alpha channel / transparency hides the colour pixels underneath.
[URL]....
In Photoline I can create a simple layer mask based on alpha (without creating a selection first), and then turn the layer mask off to reveal the "hidden" image. Or I paint with the brush and only affect the alpha.
In Photoshop I cannot seem to access that information. Nor can I paint or erase the transparency only. To me it seems as if Photoshop treats this transparency as something other than an alpha channel. The channel palette only shows the transparency.
how to convert that transparency to a layer mask, and retain the coloured pixel information? How do I access/reveal the "hidden" image?

I dunno whether there is a filter in the Photoshop that could do this covered-eye-revealing process in one click. Anyway do we have to create the eye?

I am trying to take a color photograph, turn it to black and white, and reveal a flower in color and the rest is still black and white.
I thought I had done this properly when I added a new "adjustment layer, hue/saturation", reduced saturization to zero, and painted the yellow flower over with black to reveal the yellow flower's color while the rest of the photo is still black and white. And it worked..except when I got to the green stem of the flower. Painting over that with black revealed a yellowish-green stem.
I experimented a little more by painting black on the new layer mask and most of the rest of the color photo comes out wrong. The blue sky shows up like a weird smurf blue, faces are oddly peach/orange and most colors look much different than the originial photo. Yellow seems to be not affected, magenta/pink seems to be OK and blue shows up so-so. But the rest of the colors are messed up.

I've been following one of Louis Marcoux's tutorials on youtube where he animates a gradient map inside a material in the cut out or opacity option thus creating a model reveal animation in the viewport.
In that tutorial I noticed that the animation is subject per material. I was wondering if it's possible to apply an opacity (cut out) gradient ramp to multiple materials at once so that different textures and objects on the one big object (e.g. car with different parts) can be revealed together without having to apply a gradient map to each individual material used and animating each one separately?
So the goal would be to find a simple way to apply just the one gradient ramp to the whole car and animating that.

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'm still not allowed to use the link vb, but let's try this: ....

I need to analyze an image and read the value of each pixel, exclude the highest and lowest values (perhaps anything less than 10,10,10 and greater than 245,245,245) , then average the remaining. I may need to do this on each channel of RGB.
I can almost get a result blurring the sample and then using a large brush with the info tool, but is there any other method more direct and all inclusive?

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.

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.

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.

If I am constantly making frames in photoshop for use in the video world (ie. They will be on TV) the pixels need to be rectangular (or 4x3) in aspect and not square.
I know in programs like After Effects and Combustion you can set when saving an image whether or not it is square or rectangular pixels.
How do I do this in Photoshop if it can be done?

In 2008, never had this issue.Just dumb, circles, and lines in a view port, that have hidden or center linetyoes assigned to them. When we go to plot using legacy hidden (this new for 2012?) the plot comes out with continuous lines. These are not solids. Just ordinary line entities.Now, when I change the shadeplot to "hidden" the linetype is shown correctly, but now my entities are coloured, when I just want my drawing to be black and white (going to PDF), even though all of the colours in the pen style are set to "Black".
Has this changed? Is there a new variable introduced?

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'm drawing objects (walls, platforms, etc.) in 3d made up primarily of extruded polygons. I want to be able to plot these objects in a way that hides all of the lines which are obscured by other objects. Currently I have my viewports set up with a 2D Wireframe visual style and a Hidden shade plot. This isn't working for me. I'm still getting all of the lines in the drawing visible no matter what.
Here's the strange thing: It seems to work perfectly fine in plan view, but not in front view. Also, it's worked fine in the past. It seems that the problem has gotten progressively worse over the past year or so.
I'm using AutoCAD 2008.

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!

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.

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.

I have several layers in an image, and I need to align them precisely. The ordinary layer shift ("move pixels") by multiples of pixels is not sufficient. Is there a tool or plugin for PDN that allows sub-pixel shifts (i.e. moves by fractions of pixel)? And rotations by very small angles?

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!

I mean any shape outline when using things like brush, blur, erase. If the cursor size is very small, say less that 60 pixels, the whole shape is visible. Let's just say it's a circle, if it get's any bigger it starts to disappear as the size goes up. All that will be left is a small line showing the very top left of the circle.
This is a nuisance, especially for custom brushes where I can't see where the brush will be placed.

I've seen it before but do not have an image at the moment to link to so I will try to explain it best as possible. What I want to do is take an image, then overlay another image on it that should only be really visable if you highlight the image (with both layers in it) and maybe tilt your monitor.

I have somehow accidently hidden the close, minimize and expand circles in Photoshop CS6 on a mac and now every time I want to minimize photoshop I have to go into window > arrange > minimize instead of just clicking the circle.
I have tried the tab key, the 'F' key, view > screen mode and window > arrange and none of them have worked and I cant find anything online.

Running Photoshop CS6 Normal edition (not extended)...
Was running through my preferences and for the first time I cycled through the options using the "Next Key" and found I had a preference panel that had no field descriptor on the left and looks to be for 3D rendering.
Not sure if this applied to my version of Photoshop, if it does, why no descriptor and if it does not why would it be there? The Help file suggests this is for the Extended version of Photoshop.

a picture.
if you invert it. You can really see it by using only the red channel or a high contrast.
To my question...
Is there a way to "recover" the picture?
