Struct RasterRenderer 

pub struct RasterRenderer;

Raster renderer for generating images from raster data

Implementations

impl RasterRenderer

pub fn render_to_rgba( buffer: &RasterBuffer, style: &RenderStyle, ) -> Result<Vec<u8>, RenderError>

Render a RasterBuffer to an RGBA image buffer

Arguments

• buffer - Source raster data
• style - Rendering style parameters

Returns

RGBA image data as Vec<u8> (4 bytes per pixel)

pub fn render_rgb_to_rgba( red: &RasterBuffer, green: &RasterBuffer, blue: &RasterBuffer, style: &RenderStyle, ) -> Result<Vec<u8>, RenderError>

Render RGB bands to RGBA image

Arguments

• red - Red band buffer
• green - Green band buffer
• blue - Blue band buffer
• style - Rendering style parameters

pub fn resample( buffer: &RasterBuffer, target_width: u64, target_height: u64, method: ResamplingMethod, ) -> Result<RasterBuffer, RenderError>

Resample buffer to target dimensions

pub fn read_window( buffer: &RasterBuffer, src_x: u64, src_y: u64, src_width: u64, src_height: u64, ) -> Result<RasterBuffer, RenderError>

Read a window from a buffer (subset extraction)
