That left-over shaft is not shown. -// Instead, it is sliced off because the span's CSS has overflow: hidden. - -// Thus, the reader sees an arrow that matches the subject matter width -// without distortion. - -// Some functions, such as \cancel, need to vary their aspect ratio. These -// functions do not get the overflow SVG treatment. - -// Second Brush Stroke -// Low resolution monitors struggle to display images in fine detail. -// So browsers apply anti-aliasing. A long straight arrow shaft therefore -// will sometimes appear as if it has a blurred edge. - -// To mitigate this, these SVG files contain a second "brush-stroke" on the -// arrow shafts. That is, a second long thin rectangular SVG path has been -// written directly on top of each arrow shaft. This reinforcement causes -// some of the screen pixels to display as black instead of the anti-aliased -// gray pixel that a single path would generate. So we get arrow shafts -// whose edges appear to be sharper. - -// In the katexImagesData object just below, the dimensions all -// correspond to path geometry inside the relevant SVG. -// For example, \overrightarrow uses the same arrowhead as glyph U+2192 -// from the KaTeX Main font.

That left-over shaft is not shown. +// Instead, it is sliced off because the span's CSS has overflow: hidden. +// Thus, the reader sees an arrow that matches the subject matter width +// without distortion. +// Some functions, such as \cancel, need to vary their aspect ratio. These +// functions do not get the overflow SVG treatment. +// Second Brush Stroke +// Low resolution monitors struggle to display images in fine detail. +// So browsers apply anti-aliasing. A long straight arrow shaft therefore +// will sometimes appear as if it has a blurred edge. +// To mitigate this, these SVG files contain a second "brush-stroke" on the +// arrow shafts. That is, a second long thin rectangular SVG path has been +// written directly on top of each arrow shaft. This reinforcement causes +// some of the screen pixels to display as black instead of the anti-aliased +// gray pixel that a single path would generate. So we get arrow shafts +// whose edges appear to be sharper. +// In the katexImagesData object just below, the dimensions all +// correspond to path geometry inside the relevant SVG. +// For example, \overrightarrow uses the same arrowhead as glyph U+2192 +// from the KaTeX Main font.
