Hi all,
I am happy to announce that FotoSketcher Studio 4.50 is now available for download from fotosketcher.com. A big thank you to Jack, Pat, Merwin and everyone else who tested the alpha and beta builds and sent feedback - it helped me shape this release considerably.
This version brings a new painting effect, an image watermark tool, full keyboard navigation and a rather long list of improvements and fixes.
New Gouache Painting effect 🎨
A new Gouache Painting effect joins the Painting category. Gouache sits somewhere between watercolour and oil paint: thick, opaque, with a matte finish and visible brushstrokes.
Watermark and logo tool
The "Add text" window has been expanded into "Add text/watermark". You can now load any image file (PNG with transparency, JPG, or other formats) and place it over your picture as a watermark or logo. Drag to move, drag a corner to resize, and use the floating opacity slider to control transparency. Transparent borders are cropped automatically on load, and the watermark works in scripts too.
2 new embedded scripts
Two new ready-made scripts are included, both using the new Gouache Painting effect. Open the Script Editor to try them out or adapt them to your own style.
Crosshatch improvement
The Crosshatch effect now supports the "do not erase background" toggle. This means you can draw crosshatch lines over any existing painting or drawing, combining two effects in two quick steps.
Keyboard navigation for better accessibility
Tab and Shift+Tab now cycle through controls in reading order, with a blue ring highlighting the selected item. Enter activates it, and inside effect categories the arrow keys browse effects directly.
Watercolour performance
The Watercolour effect has received a significant speed improvement. A bug that could cause issues on certain CPU configurations (Intel Xeon for instance) has also been fixed.
Before/after divider
The split-view divider has been reworked. It no longer drifts off the image, stays on the same spot when you zoom, and is correctly clamped when scrolled. It had always been a bit "iffy", I hope it behaves now 😂
Light/dark themes
The light theme has been refined for better contrast and legibility, and some remaining light/dark inconsistencies have been fixed throughout the interface.
Other improvements
- Parameters files saved with older versions of FotoSketcher are now loaded correctly.
- Watermarks are downscaled using the best possible quality for cleaner edges at small sizes.
- A little easter egg: a gentle steam animation appears on the support button's coffee cup when the mouse hovers over the icon.
- In the Script Editor window, the 3D cube animation has been optimized to consume very little CPU resource.
- A portable version for Windows (no setup needed) is now available for download in .zip format.
Bug fixes
- Fixed Escape and Enter not working correctly in some in-app windows.
- Fixed a crash in the Script Editor when the application zoom level was set below 100%.
- Fixed the right-click menu in the history gallery appearing in the wrong position at non-default zoom levels.
- Fixed taskbar flickering with an auto-hidden taskbar at fractional zoom (typically 125%).
- Fixed the Script Editor memo splitting its background into two colours.
- Brushstrokes frame and other minor corrections.
- macOS build updated with interface layout improvements.
