Struct Image

pub struct Image { /* private fields */ }

Wrapper around Fl_Image, used to wrap other image types

Implementations

impl Image

pub fn set_scaling_algorithm(algorithm: RgbScaling)

Sets the scaling algorithm

pub fn scaling_algorithm() -> RgbScaling

Gets the scaling algorithm

Trait Implementations

impl Clone for Image

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Image

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for Image

fn drop(&mut self)

Executes the destructor for this type.

impl ImageExt for Image

fn copy(&self) -> Self

Performs a deep copy of the image

fn copy_sized(&self, w: i32, h: i32) -> Self

Performs a deep copy of the image but to a new size. This will make use of the scaling algorithm when resizing.

fn draw(&mut self, arg2: i32, arg3: i32, arg4: i32, arg5: i32)

Draws the image at the presupplied coordinates and size

fn draw_ext( &mut self, arg2: i32, arg3: i32, arg4: i32, arg5: i32, cx: i32, cy: i32, )

Draws the image at the presupplied coordinates and size and offset cx, cy

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

fn as_image_ptr(&self) -> *mut Fl_Image

Returns a pointer of the image

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

Transforms a raw image pointer to an image

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

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

Transforms the image into an 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 pointers in an image (Pixmaps have more than 1, bitmaps have 0, Rgb based images have 1)

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)

Deletes the image

fn was_deleted(&self) -> bool

Checks if the image was deleted

unsafe fn into_image<I: ImageExt>(self) -> I

Transforms an Image base into another Image

impl PartialEq for Image

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
