Picutre Box Limitations?

[ctmfab]

I have created a simple vector drawing utility that draws lines into a picture box. Included is the ability to zoom in or out. When I zoom tightly into an area, the lines are drawn wrong (up vs down, etc). I have noticed that this occurs when the zoom scale is about 10% or less of the overall picture box scale.

I have stepped through my code as it executes, and all the coordinates are processed correctly. I think it is an accuracy issue with the picutre box control.

Are there any limitations on how tightly you can zoom into a picture box?

Thanks
