# printcraft-create Layer L4. Create a PDF (Acrobat's Create a PDF tool), execution plan M10.2: - `blank(width, height, pages)`: an empty document; - `from_images(&[(name, bytes)])`: one page per image, sized from the image's resolution (PNG `pHYs`, JPEG JFIF density; 72 dpi when absent). JPEG data is embedded as is (`/DCTDecode`, grey, RGB or Adobe-inverted CMYK); PNG is decoded and stored with Flate, with transparency as a soft mask; - `from_text(text, …)`: plain text set in Helvetica, wrapped and paginated. Every function returns a `printcraft_cos::Document`; the caller writes it.
