Improved image filtering – SpeedyPainter v3.4.5

SpeedyPainter v3.4.5 uses a better algorithm for alpha blending. This new solution allows to avoid image artifacts with image filtering, allowing to reduce the image graininess when zooming in and out from the image original size.

SpeedyPainter v3.4.1: autopan and autozoom during replay

In this version, during replay, the camera smoothly pans and zooms across the canvas in order to focus on those areas currently being painted.

SpeedyPainter – gradient tool usage demo

Demonstration of the behaviour of the gradient tool inside SpeedyPainter.
The gradient tool is available since SpeedyPainter v3.2.3

As you can see, the tool allows you to select color and opacity for both the gradient endpoints, and you can change those values to test the overall appearance of the image before actually applying the gradient to the image. In future versions I am planning to add a radial gradient option, as well as the possibility to add custom intermediate colors between the two endpoints.

In addition, if you define a selection mask, the gradient will affect only the selected region, as espected.

Feel free to express your usage experience and suggestions.
Thank you for watching 🙂
