Struct UnimageProcessor

pub struct UnimageProcessor { /* private fields */ }

A image processor. it can load image, resize it or clip it.

Implementations

impl UnimageProcessor

pub fn new() -> UnimageProcessor

Create a UnimageProcessor instance.

pub unsafe fn get_instance(&self) -> *mut c_void

Get the instance pointer

pub fn load_raw( &mut self, data: *mut u8, width: i32, height: i32, format: UnimageFormat, )

Load pixels from a pointer.

pub fn load_raw_from_vec( &mut self, data: &mut Vec<u8>, width: i32, height: i32, format: UnimageFormat, )

Load pixels from a Vec<u8>.

pub fn load_raw_from_slice( &mut self, data: &mut [u8], width: i32, height: i32, format: UnimageFormat, )

Load pixels from a Slice.

pub fn load(&mut self, data: *mut u8, len: u32) -> Result<(), UnimageError>

Load an image from data, if there is something wrong, it will return an error.

pub fn load_from_vec(&mut self, data: &mut Vec<u8>) -> Result<(), UnimageError>

Load an image from data, if there is something wrong, it will return an error.

pub fn load_from_slice(&mut self, data: &mut [u8]) -> Result<(), UnimageError>

Load an image from data, if there is something wrong, it will return an error.

pub fn get_width(&self) -> i32

Get the width of image.

pub fn get_height(&self) -> i32

Get the height of image.

pub fn get_format(&self) -> UnimageFormat

Get the pixel format of image.

pub fn get_error_message(&self) -> String

Get the last error message.

pub fn resize(&mut self, width: i32, height: i32) -> Result<(), UnimageError>

Resize the image.

pub unsafe fn get_buffer_as_mut(&mut self) -> *mut u8

Get the buffer of processor, it will return a pointer that points to pixels data. If it doesn’t load any image, it will return a nullptr.

pub unsafe fn get_buffer(&self) -> *const u8

Get the buffer of processor, it will return a pointer that points to pixels data. If it doesn’t load any image, it will return a nullptr.

pub fn try_clone(&self) -> Result<Self, UnimageError>

Clone the processor instance and the image buffer in it. If there is something wrong, it will return a error.

pub fn clip( &mut self, x: i32, y: i32, width: i32, height: i32, ) -> Result<(), UnimageError>

Clip the image.
