Implementations

impl Image

pub fn new(width: u32, height: u32, color_space: ColorSpace) -> Result<Image>

Create a new image of the specified resolution and colorspace. Note: no memory for the actual image data is reserved yet. You have to use Image::create_plane() to add the image planes required by your colorspace.

pub fn width(&self, channel: Channel) -> Result<u32>

pub fn height(&self, channel: Channel) -> Result<u32>

pub fn bits_per_pixel(&self, channel: Channel) -> Result<u8>

pub fn planes(&self) -> Planes<&[u8]>

pub fn planes_mut(&mut self) -> Planes<&mut [u8]>

pub fn has_channel(&self, channel: Channel) -> bool

pub fn color_space(&self) -> Option<ColorSpace>

pub fn scale(
    &self,
    width: u32,
    height: u32,
    _scaling_options: Option<ScalingOptions>
) -> Result<Image>

Scale image by “nearest neighbor” method.

pub fn create_plane(
    &mut self,
    channel: Channel,
    width: u32,
    height: u32,
    bit_depth: u8
) -> Result<()>

The indicated bit_depth corresponds to the bit depth per channel. I.e. for interleaved formats like RRGGBB, the bit_depth would be, e.g., 10 bit instead of 30 bits or 3*16=48 bits. For backward compatibility, one can also specify 24bits for RGB and 32bits for RGBA, instead of the preferred 8 bits.

pub fn set_premultiplied_alpha(&self, is_premultiplied_alpha: bool)

pub fn is_premultiplied_alpha(&self) -> bool
