fl_pixel_buffer_texture_populate()

gboolean fl_pixel_buffer_texture_populate	(	FlPixelBufferTexture *	texture,
		uint32_t	width,
		uint32_t	height,
		FlutterOpenGLTexture *	opengl_texture,
		GError **	error
	)

fl_pixel_buffer_texture_populate: @texture: an #FlPixelBufferTexture. @width: width of the texture. @height: height of the texture. @opengl_texture: (out): return an FlutterOpenGLTexture. @error: (allow-none): #GError location to store the error occurring, or NULL to ignore.

Attempts to populate the specified @opengl_texture with texture details such as the name, width, height and the pixel format.

Returns: TRUE on success.
