Hello everyone, I don't know if you have encountered such a situation before.
Through myView-> Dump (aFileName.ToCString (), Graphic3d_BufferType :: Graphic3d_BT_RGBA); the color of a picture is different from the color in the rendering scene.
The two pictures in the attachment are from the dump and the rendering scene.
Also I found that if the aFileName is a 8 bitdepth jpg,it works fine.If the aFileName is an other type lik 24 bitdepth image,It works wrong.
Thank you all.
