Methods

GdkPixbufFormat (Handle = null)

Creates a new PixbufFormat by wrapping a native handle or another wrapper.
- @p Handle is the native handle or another wrapper whose handle to adopt.
toNativeHandle (Source)

Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.
- @p Source is the raw handle, raw buffer, wrapper, or null.
- @r A raw pointer carrier or null when no pointer is present.
getLib ()

Returns the opened native library for this generated wrapper.
- @r The opened native library.
handle ()

Returns the wrapped NativeHandle.
- @r The wrapped NativeHandle.
isNull ()

Returns true when the wrapped handle is null.
- @r A bool.
describe ()

Returns a small string for debugging generated wrappers.
- @r A string.
copy ()

Creates a copy of format.
- @r the newly allocated copy of a GdkPixbufFormat. Use gdk_pixbuf_format_free() to free the resources when done.
free ()

Frees the resources allocated when copying a GdkPixbufFormat using gdk_pixbuf_format_copy()
- @r None.
get_description ()

Returns a description of the format.
- @r a description of the format..
get_extensions ()

Returns the filename extensions typically used for files in the given format.
- @r an array of filename extensions.
get_license ()

Returns information about the license of the image loader for the format. The returned string should be a shorthand for a well known license, e.g. "LGPL", "GPL", "QPL", "GPL/QPL", or "other" to indicate some other license.
- @r a string describing the license of the pixbuf format.
get_mime_types ()

Returns the mime types supported by the format.
- @r an array of mime types.
get_name ()

Returns the name of the format.
- @r the name of the format..
is_disabled ()

Returns whether this image format is disabled. See gdk_pixbuf_format_set_disabled().
- @r whether this image format is disabled..
is_save_option_supported (string option_key)

Returns TRUE if the save option specified by @option_key is supported when saving a pixbuf using the module implementing @format. See gdk_pixbuf_save() for more information about option keys.
- @p option_key is the name of an option.
- @r TRUE if the specified option is supported.
is_scalable ()

Returns whether this image format is scalable. If a file is in a scalable format, it is preferable to load it at the desired size, rather than loading it at the default size and scaling the resulting pixbuf to the desired size.
- @r whether this image format is scalable..
is_writable ()

Returns whether pixbufs can be saved in the given format.
- @r whether pixbufs can be saved in the given format..
set_disabled (bool disabled)

Disables or enables an image format. If a format is disabled, GdkPixbuf won't use the image loader for this format to load images. Applications can use this to avoid using image loaders with an inappropriate license, see gdk_pixbuf_format_get_license().
- @p disabled is TRUE to disable the format @format.
- @r None.
