* create: lift TIFF decoding buffer limit to allow print-sized images (#665) By default, the tiff crate limits decoded buffer size to 256 MiB. Set Decoder::with_limits(Limits::unlimited()) to match PNG decoding behavior and prevent 'decoder limits exceeded' on large images. * create: cap the TIFF decode buffer at 2 GiB instead of lifting it entirely (#665) A few bytes claiming enormous dimensions must still be refused, not allocated.

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 (PNGpHYs, 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, orImageResolution::Embeddedfor the same behavior asfrom_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.
