pdfcraft-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_images_with_resolution(images, ImageResolution::Dpi(dpi)): override the page resolution (1–1200 dpi), without resampling or recompressing image pixels. Use 72 dpi for one point per pixel, or ImageResolution::Embedded for the same behavior as from_images. The largest page side is still capped at 14,400 points;
• from_text(text, …): plain text set in Helvetica, wrapped and paginated.

Every function returns a pdfcraft_cos::Document; the caller writes it.
