Implement photoshop blending mode in iOS

Question

There were numerous situations when designers gave me psd files, and there two layers where set with blending mode multiply. and always I couldn't implement that behaviour, and just used different colour for front view with opacity set to, for instance, 0.5, just to some kind of simulate this blending mode behaviour. However now I just want to implement what designer has given me. For instance, let us take a UITableView. Here is the screenshot of custom design.

Here the section header isn't half opaque, but it has blending mode set to Multiply. And here is the actual colour of it

If I set custom view as a section header, with background colour set to above screenshot, how can I make the section view "blend" with the background of the UITableView???

This was just an example of the problem that I've stumbled multiple times. In general, I always have a front view and a rare view, and in photoshop front view is set, for instance, multiply blend mode with rare view, and I want to have the same effect with iOS. Is there any way to implement this??

Thanks for the answers.

Answer 1

You can use JS image processing script from Pixastic: http://www.pixastic.com/lib/docs/actions/blend/

I used this script before for several projects, it works realy great :)
