Method
ClutterImageset_data
Declaration [src]
gboolean
clutter_image_set_data (
ClutterImage* image,
const guint8* data,
CoglPixelFormat pixel_format,
guint width,
guint height,
guint row_stride,
GError** error
)
Description [src]
Sets the image data to be displayed by image.
If the image data was successfully loaded, the image will be invalidated.
In case of error, the error value will be set, and this function will
return FALSE.
The image data is copied in texture memory.
The image data is expected to be a linear array of RGBA or RGB pixel data; how to retrieve that data is left to platform specific image loaders. For instance, if you use the GdkPixbuf library:
ClutterContent *image = clutter_image_new ();
GdkPixbuf *pixbuf = gdk_pixbuf_new_from_file (filename, NULL);
clutter_image_set_data (CLUTTER_IMAGE (image),
gdk_pixbuf_get_pixels (pixbuf),
gdk_pixbuf_get_has_alpha (pixbuf)
? COGL_PIXEL_FORMAT_RGBA_8888
: COGL_PIXEL_FORMAT_RGB_888,
gdk_pixbuf_get_width (pixbuf),
gdk_pixbuf_get_height (pixbuf),
gdk_pixbuf_get_rowstride (pixbuf),
&error);
g_object_unref (pixbuf);
