notes = "colour and grayscale, bicubic, effective resolution measured where drawn (every use, with page-local UserUnit scaling, through nested forms up to 12 deep; when a use can't be measured, nothing is resampled); image fragments stacked edge to edge are merged first (side-by-side tiles not yet); monochrome (1-bit, CCITT fax, and eight-bit black-and-white grey and RGB, and indexed images that use only palette entries 0 and 1) averaged by area to 300 ppi above 450 ppi by default, a tie to the dark sample (black in grey, painted in a mask, ink in a separation, after the decode array; an indexed image's entry 0, its palette not read yet), then stored as Group 4 or 1-bit Flate (Monochrome Images ▸ Downsample to; doc_optimize mono); not monochrome images with a soft mask, halftones and dithers (most of their new pixels would cover both black and white, and their tones turn solid), or images wider than a fax row (1,048,576 samples), and Acrobat's bicubic and subsampling choices for monochrome aren't offered"
