Simple Frameworks for Displaying Bitmaps and Handling Button Presses

We have a set of applications that basically display a bunch of bitmaps and text, then allow user to press "buttons" (certain bitmaps) that cause actions to occur. We currently have these implemented using DirectX and a bunch of code to place the bitmaps and handle the button-presses. But we'd like to have the following features: por...

Using CreateCompatibleDC with mapping modes other than MM_TEXT

I have a visual C++ application that uses a CView derived class to render its display, which is primarily 3d vector data and true type text.

BitmapContext on iphone

Hello, I am repeatedly drawing to an offscreen bitmap context non-destructivly on iphone.

I need to visualize some scientific calculations. I generally prefer reusing code if there is already a good available instead of inventing wheels each time, that's why I am asking.

Monochrome BitMap Library

I am trying to create a piece of software that can be used to create VERY large (10000x10000) sized bitmaps. All I need is something that can work in monochrome, since the required output is a matrix containing details of black and white pixels in the bitmap. The closest thing I can think of is a font editor, but the size is a problem. ...

I am using BitmapFactory.decodeFile to load Bitmaps of images into my application. However, the function returns null on large images (such as those from the camera).
