## ◆ fl_pixel_buffer_texture_populate()

G_BEGIN_DECLS 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.
