◆ 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.
