Declaration [src]

void
gdk_visual_get_green_pixel_details (
  GdkVisual* visual,

)

Description [src]

Obtains values that are needed to calculate green pixel values in TrueColor and DirectColor. The “mask” is the significant bits within the pixel. The “shift” is the number of bits left we must shift a primary for it to be in position (according to the “mask”). Finally, “precision” refers to how much precision the pixel value contains for a particular primary.
