Function: buildL11BitmapHeader()

buildL11BitmapHeader(bytesPerRow, height, quality?): Uint8Array

GS v 0 raster header — 1D 76 30 quality wL wH hL hH.

bytesPerRow and height are little-endian 16-bit fields. quality is 0..3 (0 is the standard value). The raw 1-bpp bitmap (bytesPerRow * height bytes, MSB-first, 1 = black) follows the header immediately — no compression, no length field.

Parameters

bytesPerRow

number

height
