Detailed Description

Terminal image sampler for quarter- and half-pixel block glyphs.

Member Function Documentation

int donner::svg::TerminalImageViewer::calculateITermImageRows	(	int	imageWidth,
		int	imageHeight,
		int	widthPercent,
		const TerminalSize &	terminalSize,
		const TerminalCellSize &	cellSize ) const

Calculate how many terminal rows an iTerm inline image will occupy.

Parameters

imageWidth	Width of the image in pixels
imageHeight	Height of the image in pixels
widthPercent	Width percentage parameter passed to iTerm (e.g., 30 for "30%")
terminalSize	Terminal size in columns and rows
cellSize	Terminal cell size in pixels

TerminalCellSize donner::svg::TerminalImageViewer::DetectTerminalCellSize ( )

static
