Cogl.Texture.prototype.set_region_from_bitmap

function set_region_from_bitmap(src_x: Number(gint), src_y: Number(gint), dst_x: Number(gint), dst_y: Number(gint), dst_width: Number(guint), dst_height: Number(guint), bitmap: Cogl.Bitmap): Cogl.Bool {
    // Gjs wrapper for cogl_texture_set_region_from_bitmap()
}

Copies a specified source region from bitmap to the position (src_x, src_y) of the given destination texture @handle.

<note>The region updated can't be larger than the source bitmap</note>

Since 1.8

src_x: upper left coordinate to use from the source bitmap.
src_y: upper left coordinate to use from the source bitmap
dst_x: upper left destination horizontal coordinate.
dst_y: upper left destination vertical coordinate.
dst_width: width of destination region to write. (Must be less than or equal to the bitmap width)
dst_height: height of destination region to write. (Must be less than or equal to the bitmap height)
bitmap: The source bitmap to read from
Returns: true if the subregion upload was successful, and false otherwise
