CdkPixbuf.Pixbuf.get_option

### Method

# CdkPixbuf Pixbufget_option

#### Declaration [src]

    const gchar*
    cdk_pixbuf_get_option (
      CdkPixbuf* pixbuf,
      const gchar* key
    )

#### Description [src]

Looks up `key` in the list of options that may have been attached to the `pixbuf` when it was loaded, or that may have been attached by another function using cdk_pixbuf_set_option().

For instance, the ANI loader provides “Title” and “Artist” options. The ICO, XBM, and XPM loaders provide “x_hot” and “y_hot” hot-spot options for cursor definitions. The PNG loader provides the tEXt ancillary chunk key/value pairs as options. Since 2.12, the TIFF and JPEG loaders return an “orientation” option string that corresponds to the embedded TIFF/Exif orientation tag (if present). Since 2.32, the TIFF loader sets the “multipage” option string to “yes” when a multi-page TIFF is loaded. Since 2.32 the JPEG and PNG loaders set “x-dpi” and “y-dpi” if the file contains image density information in dots per inch. Since 2.36.6, the JPEG loader sets the “comment” option with the comment EXIF tag.
