I suppose I could have two crops (start and end), but I think that may be too confusing....

I was thinking of it in a different way, I want to mesh the face of an image that is a waist up picture and it's hard to set the brightness for a body image when you want to see the face. I can see your point too. I have photoshop on my computer so for me it's not an issue just thought of a way to remove photoshop from the picture would make it a more robust solution.

Thanks for the hard work though - keep it up.

I would however like to see the cropping put in front of the brightness and rotation screens.

That would not work because of two reasons:
1) Some photos are hard to see without increasing brightness and contrast first.
2) Imagine cropping first, when you rotate you will have ( unless you rotate exactly 90 or 180 degrees), extra image areas caused by the areas created by the rotation. Typically you'll have 4 right angled triangles at the corners of the image which you cannot get rid of by cropping, because the cropping phase was at the beginning of the image import Wizard.

Addition of dodge and burn along with the vignette would allow you to tweak the photo to get the best results. Don't know how much of an undertaking that is on the programming side.

That may be more a thing for an image program. Though, who knows, in the future!

I agree as well, I wouldn't miss the DXF. I would however like to see the cropping put in front of the brightness and rotation screens, and the addition of dodge and burn along with the vignette would allow you to tweak the photo to get the best results. Don't know how much of an undertaking that is on the programming side.

Thanks all for the feedback...

Agree with Ian entirely.

I only use DXF for 2D. For 3D I am only interested in STL for printing, or maybe OBJ for further processing in other applications. OBJ is universal enough, without those limitations. I doubt you can get the kind of results you want from PhotoToMesh in 32,000 vertices anyway.

After discovering inherent limits to the 3d meshes of AutoCAD I was wondering whether it was worth keeping 3d DXF mesh output in my PhotoToMesh program.

The problem with the AutoCAD DXF mesh is that it has a limit of the number of vertices of about 32,000.

So, should I maintain DXF output in PhotoToMesh, maybe making STL the default? Or get rid of it entirely, since AutoCAD accepts the limited meshes without complaint, but they are anyway wrong.
