Struct leptonica_plumbing::Pix

pub struct Pix(/* private fields */);

Wrapper around Leptonica’s Pix structure

Implementations

impl Pix

pub unsafe fn new_from_pointer(ptr: *mut Pix) -> Self

Create a new instance from a pointer

Safety

The pointer must be to a valid Pix struct.

The structure must not be mutated or freed outside of the Rust code whilst this instance exists.

pub fn read(filename: &CStr) -> Result<RefCountedExclusive<Self>, PixReadError>

Wrapper for pixRead

Read an image from a filename

pub fn read_mem( img: &[u8] ) -> Result<RefCountedExclusive<Self>, PixReadMemError>

Wrapper for pixReadMem

Read an image from memory

pub fn read_with_hint( filename: &CStr, hint: u32 ) -> Result<RefCountedExclusive<Self>, PixReadError>

Wrapper for pixReadWithHint

Read an image from memory with hints for JPEG decoding The valid hints are:

• leptonica_sys::L_JPEG_READ_LUMINANCE - only want luminance data; no chroma
• leptonica_sys::L_JPEG_CONTINUE_WITH_BAD_DATA - return possibly damaged pix

pub fn scale_general( &mut self, scalex: l_float32, scaley: l_float32 ) -> Result<(), PixManipError>

Wrapper for pixScaleGeneral

pub fn get_height(&self) -> l_int32

Wrapper for pixGetHeight

pub fn get_width(&self) -> l_int32

Wrapper for pixGetWidth

pub fn get_depth(&self) -> l_int32

Wrapper for pixGetDepth

pub fn get_data(&self) -> *mut l_uint32

Wrapper for pixGetData
