Hello,
I have my depth display set with 16 bits and I would like to display a 16 bits color image using glDrawPixel and also glTexImage2D. But I don’t know which “format” and “components” arguments to give to those functions :
GLubyte * pixels;
pixels = ....
glDrawPixels(
w,h,
format = GL_RGB ???,
type = GL_UNSIGNED_BYTE,
pixels
);
...
glTexImage2D(GL_TEXTURE_2D,
0,
components = 3 ???
w, h,
0,
format = GL_RGB??
type = GL_UNSIGNED_BYTE,
pixels
);
Argument components should be 3 as my color is RGB coded. Argument type is GL_UNSIGNED_BYTE as *pixel is a GLubyte.
So like this, OpenGL will suppose to have 3 bytes for a pixel, won’t it?
But my colors are coded with 16 bits (R->6, G->5, B->5).
Can someone give me the correct arguments please?
Thanks in advance.
Fabien
