How can I detect if a picture has a white background or not using Intervention.
My project is using a lot of picture which are either from studio in a white lab environment, or lifestyle nature images.
I would like to use a script to determine which ones have a white background.
I don't need to change the pictures in any way.

I like copy past to keep links and list, but when it comes to the colors, users does not understand that it also do takes the background color, which is white and the font color, which is black.
Then, when I render it in a gray background, users do not understand why they have white background..
Is it somehow possible to keep the copy past logic but to remove the color one?
I'm working on a report project and would like to avoid making a separate image for each indicator color. Ideally, I like to put a transparent circle in a white rectangle. I have Snag-It available and general Windows tools.
My plan is to put the Image in a table cell and change the color of the circle by dynamically assigning the background color of the cell. I think it would be much easier to embed this one image, rather than creating a bunch of different colored circles that all have to be embedded.
Any suggestions on how I can do this in Snag-It or Paint, or any tools that are free for commercial use that you can recommended for this?
This sounds like a good workaround to get an indicator with whatever color you want.
Paint.net is a free image editor that you could create this in. Start with a white square. Use the Ellipse Select tool to select a circle in the middle. Press the Delete key to make it transparent. Save it as a .PNG file and embed it in the report.
I cannot translate the DarkAqua appearance into a PDF right now. The resulting document uses a white background color. But that removes visibility of white elements in the view (which I use as part of dark mode).
I was able to influence JPG creation by providing a backgroundcolor. How do I do the same for PDF creation?
I want to be able to layer images(PNG) with blank space over other images and have the images underneath still partly visible. right now my Image loading function will prints black space where it should have the background image.
As Noah mentioned, if your PNG images don't have an alpha channel, you can use LÖVE's blend modes.

Try displaying your image with "premultiplied", for instance.
love.graphics.setBlendMode("premultiplied")
love.graphics.draw(myImage)
love.graphics.setBlendMode("alpha")
"alpha" being the default blend mode.
Is there a way to change the background color of the xcassets view in Xcode 5 or Xcode 6?
I have white images that are lost on the white background.
When viewing an image without using xcassets, the image is set against a grey background.
However with xcassets the background is white and the images can't be seen.
I've tried using different different font and color schemes but they only seem to apply to the text editor.
A reasonable work around is to select the image asset, (eg click on the 1x or 2x version) and then press the spacebar.
This will show the asset in a popover with a light grey background.
If you are happy to add an Xcode plugin (it's available via Alcatraz) then
TOCAssetCatalogBackground solves this problem. https://github.com/toco/TOCAssetCatalogBackground
Are the images essentially silhouettes? If so, you could make them in another color (I like to use magenta, because then it’s immediately clear when something isn’t working). Then you can use iOS 7’s -[UIImage imageWithRenderingMode:] (not sure if there is a Mac equivalent) to have the image automatically pick up the tint color of its containing view. Then you would not be looking at white images on a white background.
