I have a PDF that has a light yellow background for each page which if printed in black & white produces a gray background as expected. No problem here.
But now I want to set the background to white to save ink. There's a feature to do this in the Preferences of Adobe Acrobat Reader DC (64-bit). I'm setting the background to white using these settings:
This produces the correct print output preview of white, but when I print the page it still behaves like nothing has changed and I still get a gray background like in the print preview before settings were changed. Why does it not work? How do I properly set the settings so it truly prints no gray background, just white?

I downloaded Unreal Engine 5.0.1 recently and created an RPG project. But once the project loaded,
the playground and every other object in it were orange in colour;
and the player didn't show up on the screen either. The player was
only visible in the "Play" mode, but it was orange in colour too.
see viewport image here
The only way I could see the player or any other material in its original grey colour was when I double-clicked on them in the content folder and viewed them separately.
see player's viewport image here
I checked to see if the material colours of the objects are orange too. But they were all shades of grey.
I tried adding a new cube and it came out white (not orange). Then I replaced its material with the other grey colour materials available in the project. The only thing that changed was the material texture of the object. The colour switched back to orange again.
I checked and unchecked all the things in the "show" menu, but it didn't help either.
This was the very first project I created right after I downloaded Unreal Engine. None of the default settings was changed.
How can I make the player visible, and how do I get the orange colour to change back to the original grey colour?
I found it!
You need to uncheck Visible, in the Rendering drop-down menu in the SkyAtmosphere Actor.
I have a colored image from photoshop where the background is transparent well as some other spots. After using image scan and expand, the transparent background was gone so I reselected the design I made and copied it to another layer. The white background is gone, however, I see that there are still white spots in the design that wasn't transparent.
I selected them and deleted them, but, it gives me black instead of transparent.
I'm out of ideas as to how to make these white spots transparent. The same thing with my signature- although I can erase it completely, if I just erase the white parts, I get black.
I clicked on the foreground/background little square tool icons, selected the color I want and clicked ok. The small tool icon is showing the new color but the image itself hasn't changed the color. And yes confirmed that the mode is RGB.
You need to use a tool to apply the color as needed...
Did you use the paint bucket or brush to actually add the new color to the image?
Simply changing the color of this box does not change the foreground background color automatically
I have been trying to save for web from a psd file, The .PNG file that I get has no transparency and instead all transparent area is filled with white.
I am beginner in Photoshop, How can I accomplish this task?
Normally if you are doing save for web in png 8 format it will take white color instead of transparency to avoid this white color You have to do save for web as png 24 format then u will get transparency without white color
The Problem got Solved, the App/program i was using had some problem and was not showing the background to be transparent, have tried it on another program and its OK
Thanks to Anthony who helped alot.
I am having some problems with the PDF files that I make using the PDFSharp library. The files are ok as long as I am viewing them normally.
However I need these files to be changed using the accessibility options (Edit -> Preferences -> Accessibility (in the left menu Categories) -> Report Document Colors -> Custom Color). Whenever there is image with transperancy and/or transparent masks and the Background color is set to black everything disappears.
I looked at the PDFSharp code and it seems that they are setting some transparent SMask, which I did not find to do anything noticeable (at least for me), but I am not sure if I disable it will it screw up something that I cannot think of.
Most probably I won't get help on this one, but I hope that someone knows something more about this problem with PDF Transparency and the Accessibility options.
The transparency mask is created for images with transparency only.
So if your images contain black lines and a transparent background and you change the color of PDF pages to black, you will see black lines on a black background - you will see nothing.
If your images contain black lines on a white background, you will see your image as you know it: black lines on a white background.
Transparency is a feature, it's optional.
Maybe there's a bug in PDFsharp. If I watch the output of the Graphics sample with black background color, pages 4 and 5 are completely black (looks wrong to me).
The output of the Hello MigraDoc sample looks correct to me. The image on page 1 does not use transparency and keeps it white background, the chart on page 6 is transparent (which leads to black lines on a black background).
But maybe that's a bug in Adobe Reader - everything looks fine if I do not set a background color, but activate the transparency grid instead.
If you think that your images do not contain transparency, then we'll need files (PDF and image) for further examination.
Edit: I just checked the output of the Graphics sample with Adobe Acrobat 5 - all pages display correctly even with black background color. With Adobe Acrobat 8 and Adobe Reader X pages 4 and 5 are black. Looks like a bug in Adobe Acrobat/Reader to me.
