v0.3.0-alpha — safe saving, save modes, resize, export

Photo2Mac v0.3.0-alpha — saving you can trust, a choice of save modes, resize, export, and a notarized download.

Please update from v0.2.1

Saving in v0.2.1 and earlier could damage photos:

• reopening a saved file applied the edits a second time, and each further save compounded them;
• saving dropped the camera data, capture date, GPS, copyright and the colour profile;
• an off-centre crop kept the vertically mirrored part of the image.

All three are fixed. Files saved by those versions open as already edited: their recorded edits are shown in the metadata panel and never applied again.

Saving

• Three save modes, chosen in Settings: Save what you see (the file becomes the edited image — the default), Never modify the original (edits go into a .p2m file next to it), Keep the original inside (the edited file carries the original, so you can always go back). Each file records how it was written, so changing the setting never breaks what is already on disk.
• EXIF, GPS, copyright, XMP from other apps and the colour profile are kept. A format macOS cannot write (WebP) is no longer silently saved as JPEG under the old name; you are pointed to Save As.
• Save As (Cmd+Shift+S) moves the document to the new file. Export (Cmd+Shift+E) writes a copy in JPEG, PNG, HEIC or TIFF, with a chosen quality and maximum size, and leaves the document as it was.
• Unsaved changes show as a dot in the tab; closing a tab, the window or the app asks first.
• Unsaved edits are autosaved and offered back after a crash, but only while the file is the same one they were made on.

Editing

• Resize: pixels or percent, proportions kept, long-edge presets 1920 / 1200 / 800. It is the last step, so it can be changed or removed at any time.
• Before / after: hold the toolbar button or the \ key.
• Folder paging: ← / → on the image or Cmd+[ / Cmd+] open the previous / next image in the folder, replacing the tab only when it has nothing unsaved.
• A crop now stays on its subject when you rotate afterwards, and the flip buttons mirror the image as you see it, also when it is rotated.
• The crop tool keeps the existing crop while it is open (saving mid-crop no longer saves the photo uncropped), works with the inspector hidden (Return applies, Escape cancels) and its handles keep their size at any zoom.
• Grayscale photos can be edited — before, every edit was silently ignored.
• High-resolution photos tagged at 300 dpi no longer jump in size on the first edit or report wrong dimensions.
• The histogram reads like other editors (sRGB values; it used to look underexposed) and is computed in the background.
• Cancel in a tool no longer restores another tab's state.
• The unfinished annotation tools are hidden until they work.
