We have a VB.Net app and one routine is too slow in VB.net so we need a quick solution in C++. It's real simple and any decent C++ programmer could accomplish this in a matter of minutes.
We have an app that manipulates a small bitmap (300x216) for displaying various things. There are various instructions carried out on the bitmap and most of them are simply drawing pixels. There is a need to "scroll" the image up, down, left, or right by X amount of pixels. The problem is that the bitmap is (and needs to stay) a 4bpp indexed palette image, and, unfortunately the graphics object in .Net won't work with images that have an indexed palette. Our only solution so far moves each pixel one by one but that is too slow for our app.
What we basically need is a DLL we can call that will scroll the bitmap in any direction by any amount of pixels, and wrap (meaning if we scroll 6 pixels to the right, the 6 pixels that got pushed off the right will wrap around to the left side).
The DLL needs to be written in Visual C++ 2005 or 2008. Upon receipt of the DLL and the source code (and a quick test to verify that it works), I will send $100 immediately via PayPal to the account of your chosing.
If you understand what we need, and this sounds like a piece of cake to you, and you want to make a quick $100, please inquire via our tech support page as we don't want to disclose any email address here.
