Labview-C # rotate bitmap image

[alexderjuengere]

transparent in regards to the .vi's frontpanel background?

I don't think that's possible with the dotnet picture box, use the built-in LabView image to achieve this.

within the dotnet picture box, you can set each pixel's alpha channel from 0 to 255

e.g. all pixel of the rotated image to alpha = 255, all the black background pixels to 0

or vice versa

Hi, @constructionworker,

For the benefit of the next person to come along, could you please answer these questions?

• What method did you use to solve your problem?
• In your particular case, what made your method preferable to @alexderjuengere's solution?

Thanks,

I am trying to add the bitmap image to the Gmap.Net map. I need to rotate the image. but after doing it with the method alexderjuengere showed, I could not add it to the example made with Gmap.Net. I ran into some problems. I could not see the image as transparent. I commented on the C # examples made with 'Gmap.Net.Windows.dll' to Labview. Now I can transparently add a PNG file I want to the map and rotate it. This is how I solved this problem.
