I need to capture rendered images from camera. The code:

image.clear();
viewport.renderImage2D(camera, image);

Where are pixels has been stored?

Hi,

 

Image pixels stored in RAM, Texture pixels stored in VRAM.

Thank you, silent! I have got one more question.

 

I create Image with RGB8 pixel format, but after rendering it have been RGB16F. Why is this happening?

I tried to save RGB16F image into file. But error message "Image can't save RGB16F format into the file" has been printed. 

I tried to convert image to RGB8 format via converToFormat function, but the same error has been printed. 

 

How to save image into file? How to convert pixel format?

Hi,

 

Could you post a small code snippet that we can test in newly created C++ project to get an idea what is going on?

Thanks!

Now it works fine, it was my fault. I don't properly set up texture object.
