Grx.Context.new_full

function new_full(mode: Grx.FrameMode, w: Number(gint), h: Number(gint), memory: Grx.FrameMemory, where: Grx.Context): Grx.Context {
    // Gjs wrapper for grx_context_new_full()
}
  

Creates a new context in system memory using the memory layout specified by mode.

memory must contain Grx.frame_mode_get_n_planes pointers (usually just one, but could be as many as 4) of size Grx.frame_mode_get_plane_size. null may also be passed to memory, in which case the memory will be dynamically allocated.

Likewise, where can be an unused Grx.Context (e.g. you may want to do this if you want a stack allocated context) or it can be null to dynamically allocate a new context.

mode

the frame mode

w

the width of the context

h

the height of the context

memory

memory location(s) or null

where

an unused Grx.Context struct or null

Returns

where or a new context if where was null. Returns null on error.
