Defines the methods implemented by all image types

Required methods

fn copy(&self) -> Self where
    Self: Sized, 

Performs a deep copy of the image

fn draw(&mut self, x: i32, y: i32, width: i32, height: i32)

Draws the image at the presupplied coordinates and size

fn width(&self) -> i32

Return the width of the image

fn height(&self) -> i32

Return the height of the image

fn w(&self) -> i32

Return the width of the image

fn h(&self) -> i32

Return the height of the image

unsafe fn as_image_ptr(&self) -> *mut Fl_Image

Retunrs a pointer of the image

Safety

Can return multiple mutable pointers to the image

unsafe fn from_image_ptr(ptr: *mut Fl_Image) -> Self where
    Self: Sized, 

Transforms a raw image pointer to an image

Safety

The pointer must be valid

fn to_rgb_data(&self) -> Vec<u8>

Returns the underlying raw rgb image data

fn to_raw_data(&self) -> *const *const u8

Returns the underlying raw image data

fn to_rgb(&self) -> Result<RgbImage, FltkError>

Transforms the image into an RgbImage

Errors

Errors on failure to transform to RgbImage

fn scale(
    &mut self,
    width: i32,
    height: i32,
    proportional: bool,
    can_expand: bool
)

Scales the image

fn count(&self) -> i32

Return the count of an image

fn data_w(&self) -> i32

Gets the image’s data width

fn data_h(&self) -> i32

Gets the image’s data height

fn depth(&self) -> ColorDepth

Gets the image’s depth

fn ld(&self) -> i32

Gets the image’s line data size

fn inactive(&mut self)

Greys the image

unsafe fn delete(img: Self) where
    Self: Sized, 

Deletes the image

Safety

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

fn was_deleted(&self) -> bool

Checks if the image was deleted

unsafe fn increment_arc(&mut self)

INTERNAL: Manually increment the atomic refcount

Safety

The underlying image pointer must be valid

unsafe fn decrement_arc(&mut self)

INTERNAL: Manually decrement the atomic refcount

Safety

The underlying image pointer must be valid

unsafe fn into_image<I: ImageExt>(self) -> I where
    Self: Sized, 

Transforms an Image base into another Image

Safety

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