I've got some code that resizes an image so I can get a scaled chunk of the center of the image - I use this to take a UIImage and return a small, square representation of an image, similar to what's seen in the album view of the Photos app. (I know I could use a UIImageView and adjust the crop mode to achieve the same results, but these...

I would like to load a BMP file, do some operations on it in memory, and output a new BMP file using C++ on Windows (Win32 native). I am aware of ImageMagick and it's C++ binding Magick++, but I think it's an overkill for this project since I am currently not interested in other file formats or platforms. What would be the simplest way ...
I'm trying to draw images on the iPhone using with rounded corners, a la the contact images in the Contacts app. I've got code that generally work, but it occasionally crashes inside of the UIImage drawing routines with an EXEC_BAD_ACCESS - KERN_INVALID_ADDRESS. I thought this might be related to the cropping question I asked a few weeks...

And maybe it's a stupid question but I was wondering if there is a way to generate a polygon with 4 points, so that the user can himself drag each point to create it's own (As an example, let's say that we want to remove a window from an image that it is not at a normal angle) .Is it possible?. ...

I also have code to capture a screen shot of the current desktop. I would like an algorithm that will help me find the target i...
-Edit- FYI.. I am converting b&w documents scanned in as greyscale or color. 1)The first solution worked, it just reversed black & white (black background, white text). It also took nearly 10 minutes. 2)The JAI solution in the 2nd answer didn't work for me. I tried it before posting here. Has anyone worked with other libraries free ...
I'm writing some code to scale a 32 bit RGBA image in C/C++. I have written a few attempts that have been somewhat successful, but they're slow and most importantly the quality of the sized image is not acceptable. I compared the same image scaled by OpenGL (i.e. my video card) and my routine and it's miles apart in quality. I've Google ...
