Quick Java/Blackberry app fix - $30

It's basically ONE java function for image blending that overlays one image over another. It's like when an user changes a scroller value, it overlays correspondingly. It uses BufferedImage of general java. BlackBerry api doesn't have BufferedImage but a Bitmap class having similar functions. The general java function does RGB bit swifting for blending. Need this working on Blackberry JDE4.5, it's already ported into the Blackberry app, but right now it outputs nothing/white image. The job is to fix the image blending function to get it working like general java version of the app. Need this done Today. Potential applicant shall receive both versions of the app. You must send a fixed demo before hiring. Do not apply if you are not 100% sure or not agree with the above. Must have BlackBerry JDE 4.5 and a general java editor installed.
