writeRgbaPixelsToPngFile()

bool donner::svg::RendererImageIO::writeRgbaPixelsToPngFile ( const char * filename, std::span< const uint8_t > rgbaPixels, int width, int height, size_t strideInPixels = 0 )

static

Write raw RGBA pixel data to a PNG file.

Parameters

filename	Filename to save to.
rgbaPixels	Span containing RGBA-ordered pixel data.
width	Width of the image.
height	Height of the image.
strideInPixels	Stride in pixels. Defaults to 0, which assumes a stride of width.

Returns

true if the image was written successfully.

writeRgbaPixelsToPngMemory()

std::vector< uint8_t > donner::svg::RendererImageIO::writeRgbaPixelsToPngMemory ( std::span< const uint8_t > rgbaPixels, int width, int height, size_t strideInPixels = 0 )

static

Write raw RGBA pixel data to a PNG in memory.

Parameters

rgbaPixels	Span containing RGBA-ordered pixel data.
width	Width of the image.
height	Height of the image.
strideInPixels	Stride in pixels. Defaults to 0, which assumes a stride of width.

Returns

Vector containing the PNG-encoded data.
