Release v2.2.6
Version 2.2.6 with a new unified Transition window, a fully featured Modifications window, four new brick segmentation methods, new brick transition sections (Shadow, Underfilling, Tile Visibility Pen and Eraser), and quality-of-life additions to the main window.
1. New Modifications Window
- New Modifications Window: For quick and efficient on the fly image modifications.
- Basic & Color Adjustments: Added standard sliders for tone (Exposure, Contrast, Highlights/Shadows, Whites/Blacks) and color (Saturation, Vibrance, Hue, Temperature, Tint).
- Color Overlay: Blends a chosen color with textures using an eyedropper, color picker, and advanced mix modes (including OKLab Chroma with Luma/Chroma tuning).
2. Transition Helper Window
- Unified Workspace: Merged Smooth and Brick transition interfaces into a single window, toggled easily via radio buttons.
- Instant Previews: Added an Apply button to review transitions without closing the window.
3. Brick Analysis & Segmentation
- New Segmentation Methods: Added Felzenszwalb, SLIC, Quickshift, and Grid Fit alongside existing methods, all equipped with dedicated tuning sliders.
- Updated Existing Methods: Added a Marker Count slider to Watershed and an Angle adjustment to Brick Fit.
-
Gaussian Filter: Added a new pre-processing blur filter with adjustable
$\sigma$ radius.
4. New Brick Workflow Tools
- Shadow Expander: Adds color-picking, sizing, and hardness controls for shadows behind tile borders.
- Underfilling Expander: Adds intensity and position controls, including a reverse toggle to turn underfilling into overfilling for bright/sandy textures.
- Manual Editing Pen: Allows manual painting (Pen, Eraser, Reset) directly on the result image to force tiles as visible or hidden.
5. Other
- Main window / Target panel: hold Space while clicking or dragging to make a free (grid-independent) selection; release Space to return to normal grid-snapped behavior.
- Main window (Avalonia UI): Copy / Paste (
Ctrl+C/Ctrl+V) support added. - Release build lineup changed: the combined release now ships three packages —
TgaBuilder-Standard-Vx.x.x.zip(WPF .NET 6, requires .NET 6 runtime),TgaBuilder-PreviewAvalonia-Windows-Vx.x.x.zip(Avalonia UI, Windows, self-contained), andTgaBuilder-PreviewAvalonia-Linux-Vx.x.x.zip(Avalonia UI, Linux, self-contained). The former separate WPF .NET 8 and non-self-contained Avalonia builds are no longer included. - New Homepage: Newly and freshly designed homepage.
- Documentation: A new set of documentation that collects all the information necessary for effective usage in one location.
If you have Windows 10/11 and either Tomb Editor version 1.9 or later or the .NET 6 runtime installed, use the standard version. Otherwise, use one of the Avalonia preview versions.
