Struct fltk::image::Image

pub struct Image { /* fields omitted */ }

Wrapper around Fl_Image, used to wrap other image types

Implementations

impl Image

A conversion function for internal use

pub unsafe fn as_ptr(&self) -> *mut Fl_Image

Returns the internal pointer of Image

Safety

Can lead to multiple mutable pointers of the same image

pub unsafe fn from_raw(ptr: *mut Fl_Image) -> Self

Initialize an Image base from a raw pointer

Safety

Can be unsafe if given an invalid pointer

pub unsafe fn into<I: ImageExt>(self) -> I

Transforms an Image base into another Image

Safety

Can be unsafe if used to downcast to an image of different format

pub unsafe fn delete<I: ImageExt>(img: I)

Deletes an image

Safety

An image shouldn't be deleted while it's being used by a widget
