What image control will work best?
Posted on 1999-01-28
I have the following problem.
I will be using TIFF images and I need to do the following.
1) Load the image into a control inversed (invert the colour). So Black is
white and white is black. The images will only be in b&w.
2) Need to create zones(areas) on the image to highlight based on a button click. This means that when command1_click occurs a preset zone will be inverted back to the proper colour (set black to white, white to black).
3) Needs to understand that if the area I need is off the screen it will automatically scroll there for the user.
I know that this all sounds straight-forward but the problem is this:
Loading an image is easy. Some controls allow me to do the invert while some don't and I need to use the BitBlt API call. While some control don't have HDC so I can't use API (as far as I know).
The real headache is if they allow HDC and I can send a part of the image to invert it, I still need to somehow 'melt' or 'burn' the new part into the existing image.
Anyone have a suggestion. I have tried the followingWang
Eastman Kodak (does not have a demo that I could find)ImageKnife, LeadTools, Kofax
I think that with a better knowledge of ImageKnife and LeadTools I could get it working but they both have a ton of extras I don't need and don't feel like paying for (unless it is a last resort). Thanks in advance....
