Data to load.

The argument can be NULL.

The data is owned by the caller of the function.

Type: gint

The suggested height of the constructed pixbuf, or 0 for the native size.

flags

Type: AscImageLoadFlags

A AscImageLoadFlags, e.g. ASC_IMAGE_LOAD_FLAG_NONE.

format_hint

Type: AscImageFormat

Assume the specified image format for data, use ASC_IMAGE_FORMAT_UNKNOWN to guess.

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 a NULL GError*.

The argument will be left initialized to NULL by the constructor 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.
