[vtk-developers] 2D DrawImage() API

[Eric E. Monson]

Hey Marcus,

Thanks a lot for getting around to that -- I appreciate it. (I seem to be having another problem that's keeping me from testing your new commit, but I'll let you know if I have any problems with it. From the diff it looks like it will work well for me.)

Now I think the only outstanding issue that keeps me from using the master branch is this little issue with vtkChartXY.cxx

If you could take a look at it sometime it would be wonderful.

Thanks again,
-Eric

I retained the original function signature, and added a new one where a scale can be applied (commit 6e5f596). Let me know if this does not satisfy your requirements for some reason.

Probably the former is more generic for that type of low-level routine and people can just calculate a scaling factor on the front end to adapt the size...

I don't have time right now, but I have added this to my list of emails to follow up on. I will try to get this integrated into VTK in the next few days. Either verbatim, or slightly modified to fit with some other work and wrapping.
