* M10: exported TIFF and JPEG pages record the resolution they were drawn at A page exported as TIFF said 1 x 1 with no unit, whatever the dpi, and a JPEG export said nothing, so other programs showed and printed them at a default (a 300-dpi page shown at 72 dpi is four times too big). encode_image now takes the dpi: TIFF X/YResolution in inches, the JFIF density in dots per inch. PNG stays without pHYs. It counts pixels per metre, so 72 dpi would read back as 72.009, and a page made from an exported PNG (doc_create from images, as enhance_camera_image_through_tools does) would come out 0.01% small. Exporter records the resolution a page was actually drawn at (dpi_used), so a page too large for the renderer says the lower one. render records --dpi, since it refuses oversized pages. The TIFF is written with the tiff crate, already in the graph, because image's TiffEncoder can't set a resolution. * M10: TIFF page exports are LZW-compressed, as documented encode_tiff's comment said "LZW-compressed by the encoder's default", but the TIFF was written uncompressed: a Letter page at 300 dpi came to 25 MB. It is now LZW without a predictor, the compression TIFF readers support most widely after none. * Contributors: add my name for the About window
