Development log
- Rebuilt resizing in the image converter. For one image you enter the width × height, and for several you choose a rule such as percentage, long edge, width or height.
- Replaced the camera RAW handling and checked it with samples in 10 formats. Olympus, Samsung and Pentax files open with larger previews.
- Translated every screen in the app into English.
- Prepared the Microsoft Store release. The app now appears in “Open with” for 71 file extensions, and two problems that only affected the Store version are fixed: settings that weren't saved and a desktop background that didn't stick.
- Made the macOS build, and hid the printing and desktop background menus, which aren't available there.
- Redrew all icons as SVG, so none of them show up as empty boxes on macOS.
- Tuned the release build, taking the executable from 36.77 MB to 32.91 MB. Error handling stayed in, so one damaged image won't close the whole app.
- Made the first beta, with archive viewing, two-page view, webtoon mode, the thumbnail browser and the image converter.
