What's New
FreeCCR 1.1.1 — fixes for the macOS scanner-TIFF reports (issues #86 and #87). Thanks for the detailed reports!
- B/W-point conversion no longer fails on macOS. The .app launches with an ASCII console encoding, and a diagnostic log line crashed every conversion with
'ascii' codec can't encode character…("Convert All" silently produced un-inverted frames). Logging can no longer abort any operation. - Pakon / Nikon Coolscan TIFFs load correctly. Planar TIFFs (Pakon
expRGBexports) were silently decoded with scrambled channels; LZW/deflate-compressed scans could take minutes or never finish loading; float and wide-integer sample formats rendered black. All fixed. - Consistent film-base colour on import. The un-converted preview's auto-brightness no longer shifts hue per frame — the film base reads the same colour on a mostly-blank frame as on an exposed one. (Display only; conversion and export are unchanged.)
