easy rendering for Rhino in Windows

Error Saving Bitmap as PNG

After updating to the 10 Mar version, I am getting errors in attempting to "Save with alpha channel" as a .png file. Is this a bug, or a problem with my config?

Hello David,

I forgot one other important question, what version of Windows are you running on and do you have the latest updates installed?

Thanks for the update, I modified the test harness one more time and cranked up the image resolution to 1024x768 and update the bitmap pixels in the same manner as Flamingo prior to saving the bitmap. This should be as close to what Flamingo does as possible. I also compiled with the .NET 2.0 compiler, the previous app was compiled using .NET 4.0.

Please give the new application a try and let me know if you are able to save bitmaps to your desktop.

Thanks for testing, I will have to dig around some more in Flamingo nXt to see what is different that might be causing your problem. I will try to have an answer for you soon.

Can you save a PNG from Flamingo to your desktop?

I'm getting the error saving png files again. I havent changed anything in rhino 4 where I'm doing the rendering. I did however download the latest Rhino 5 WIP. I don't know that could have any effect. I get the same error trying to save in Rhino 5.
