Struct MaaImageBuffer 

pub struct MaaImageBuffer { /* private fields */ }

Image buffer for storing and manipulating image data.

Supports raw BGR data and encoded formats (PNG/JPEG). Compatible with OpenCV image types.

Implementations

impl MaaImageBuffer

pub fn new() -> MaaResult<Self>

Create a new buffer.

pub unsafe fn from_raw(handle: *mut MaaImageBuffer) -> Self

Create from an existing handle.

Safety

This function assumes the handle is valid. The returned buffer will NOT take ownership of the handle (it won’t be destroyed on drop). Use this when you are borrowing a handle from the C API.

pub fn from_handle(handle: *mut MaaImageBuffer) -> Option<Self>

Create from an existing handle safely (checks for null). Returns None if handle is null.

pub fn as_ptr(&self) -> *mut MaaImageBuffer

Get the underlying raw handle.

pub fn raw(&self) -> *mut MaaImageBuffer

Get the underlying raw handle (alias for as_ptr).

impl MaaImageBuffer

pub fn is_empty(&self) -> bool

Check if the buffer is empty (contains no image data).

pub fn clear(&mut self) -> MaaResult<()>

Clear the buffer, releasing any image data.

pub fn width(&self) -> i32

Get the image width in pixels.

pub fn height(&self) -> i32

Get the image height in pixels.

pub fn channels(&self) -> i32

Get the number of color channels (e.g., 3 for RGB, 4 for RGBA).

pub fn image_type(&self) -> i32

Get the OpenCV image type constant.

pub fn to_vec(&self) -> Option<Vec<u8>>

Get the encoded image data as a byte vector (PNG format).

pub fn raw_data(&self) -> Option<&[u8]>

Get the raw image data (BGR format, row-major).

pub fn set_raw_data( &mut self, data: &[u8], width: i32, height: i32, img_type: i32, ) -> MaaResult<()>

Set the image from raw BGR data.

pub fn set(&mut self, data: &[u8], width: i32, height: i32) -> MaaResult<()>

Set the image from raw BGR data (assuming 3 channels, CV_8UC3).

pub fn set_encoded(&mut self, data: &[u8]) -> MaaResult<()>

Set the image from encoded data (PNG/JPEG).

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

Resize the image.

• width: Target width, 0 for auto aspect ratio.
• height: Target height, 0 for auto aspect ratio.
