Hello, I'm currently writing a 3D app , and want to save an image from a screen with 3D objects in it with SaveImage() : after several days of attempts I discovered that SaveImage() only works if the 3D objects are NOT colored with SetObjectColor() , otherwise the object itself does not appear in the output image.
With text instead, SaveImage() works also with SetTextColor(). This happens for both AppGameKit 2 & AppGameKit Studio.
If needed , I can provide my code and sample output images for this situation.
Thank you, regards
Giorgio

try this:


it's my first time playing with GetImage() but it works. saving as PNG, tho... i'm not sure what i need to do to retain the background color in the file (.jpg is fine).

otherwise, i'd consider SetRenderToImage(), instead (which, IIRC, retains the BG color).

meanwhile, show us a code example where i'm not experiencing any "black and white" issues:

Hello, first of all thank you so much both Virtual Nomad & PSY Labs for your replies !
Both snippets work as expected on my system (pls see attached test.png & test1.png where I have set cylinders instead of boxes) , and that's exactly what I did in my code :
Render()
simg = GetImage(0,0,G_width,G_height)
SaveImage(simg,"cake.png")
G_width & G_height of course are both initialized and valid values.
The only difference from your code is that I'm currently using LAG_Library 0.77 (which I found on the forums) for building menus & buttons on screen, and it's probably this library that doesn't perform well, even if I couldn't believe it ! It uses sprites for menus , and as you can see in attached testcake.png, only B&W object (a rose) and menus are visible.
Thank you very much again for your help! ... May I ask you : are there any other menus building frameworks currently available on the forums or is it better to build them on my own ?
Best regards,
Giorgio
