Method
ClutterImageset_area
Declaration [src]
gboolean
clutter_image_set_area (
ClutterImage* image,
const guint8* data,
CoglPixelFormat pixel_format,
const MtkRectangle* rect,
guint row_stride,
GError** error
)
Description [src]
Sets the image data to be display by image, using rect to indicate
the position and size of the image data to be set.
If the image does not have any image data set when this function is
called, a new texture will be created with the size of the width and
height of the rectangle, i.e. calling this function on a newly created
ClutterImage will be the equivalent of calling clutter_image_set_data().
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.
Parameters
data-
Type: An array of
guint8The image data, as an array of bytes.
The data is owned by the caller of the method. pixel_format-
Type:
CoglPixelFormatThe Cogl pixel format of the image data.
rect-
Type:
MtkRectangleA rectangle indicating the area that should be set.
The data is owned by the caller of the method. row_stride-
Type:
guintThe length of each row inside
data. error-
Type:
GError **The return location for a recoverable error.
The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby the method if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
