Struct basis_universal::encoding::CompressorImageRef

pub struct CompressorImageRef(pub *mut basisu_image);

Implementations

impl CompressorImageRef

pub fn invalidate(&mut self)

Sets the image to be completely empty (i.e. 0 width, 0 height). (This was called clear in the upstream API.)

pub fn resize(&mut self, width: u32, height: u32)

Resizes the image to the given width/height

By default the pitch will be equal to the width. To customize this, use resize_with_pitch

pub fn resize_with_pitch(&mut self, width: u32, height: u32, pitch: u32)

Resize the image to the given width/height with a custom "pitch". The pitch is the offset between rows and is not needed for all formats. By default, the pitch will be equal to the width

pub fn init(&mut self, data: &[u8], width: u32, height: u32, channel_count: u8)

Resize the image and populate it with the given data.

channel_count should be the number of channels in the image (so >=1 and <= 4)

pub fn pixel_at(&self, width: u32, height: u32) -> Option<ColorU8>

pub unsafe fn pixel_at_unchecked(&self, width: u32, height: u32) -> ColorU8

pub fn width(&self) -> u32

pub fn height(&self) -> u32

pub fn pitch(&self) -> u32

pub fn total_pixels(&self) -> u32

pub fn block_width(&self, w: u32) -> u32

pub fn block_height(&self, h: u32) -> u32

pub fn total_blocks(&self, w: u32, h: u32) -> u32

pub fn pixel_data_mut(&mut self) -> &mut [ColorU8]

pub fn pixel_data_u8_mut(&mut self) -> &mut [u8]

pub fn pixel_data_u32_mut(&mut self) -> &mut [u32]
