Return a copy with x and y axes swapped.

Pre-blends the 16-level Alpha4 gradient against bgcolor into a palette. This lets glyph rendering use Indexed4 (a simple table lookup) instead of Alph

In a single quadrant, the nearest and farthest distances occur at opposite rectangle corners, so the classifier can bound the whole tile with two squa

Scans a row of nibbles starting at (data, phase) for the first nibble that differs from 'value'. Returns the offset (in nibbles from start) of the fir

Advance the buffer after direct writes via `buffer_ptr()`.

Return a common name for this orientation.

Return raw access to the buffer at the current write position.

Clip this box to the given clip box. @return Clip result indicating whether the box was reduced or emptied.

Also used to draw circles, in a special case when radius is half of the box length.

Return a best-effort lower bound on excluded pixels in raster order starting at `(bounds.xMin(), y)`. The caller must only use this when the current
