Paint.NET 4.0 Build 5268 Beta

Paint.NET is an image and photo manipulation application. Every feature and user interface element was designed to be immediately intuitive and quickly learnable without assistance. In order to handle multiple images easily, Paint.NET uses a tabbed document interface. The tabs display a live thumbnail of the image instead of a text description. This makes navigation very simple and fast.

Usually only found on expensive or complicated professional software, layers form the basis for a rich image composition experience. You may think of them as a stack of transparency slides that, when viewed together at the same time, form one image.

Many special effects are included for enhancing and perfecting your images. Everything from blurring, sharpening, red-eye removal, distortion, noise, and embossing are included. Also included is our unique 3D Rotate/Zoom effect that makes it very easy to add perspective and tilting.

Adjustments are also included which help you tweak an image's brightness, contrast, hue, saturation, curves, and levels. You can also convert an image to black and white, or sepia-toned.

What's new in this version:

The Line/Curve tool is now back, and the Line and Curve shapes have been removed from the Shapes tool
Improved rendering quality of the Line/Curve tool, especially when antialiasing is disabled
Rectangle and Rounded Rectangles shapes now draw using an "inset" brush stroke. This helps prevents blurriness with odd-sized brush widths
Shapes tool now lets you commit by clicking outside of the bounding box of the current shape. (you can also start drawing a new shape via clicking and dragging, of course)
Improved rendering quality of brush tools when antialiasing is disabled
Improved performance of Shapes and Line/Curve tools on most systems (e.g., less than 8 CPU cores)
Improved rendering quality of Image->Resize when using Nearest Neighbor
Fixed the Palette chooser in the Colors window, which was going away when you tried to move the mouse to click on one of its items
Fixed some broken clipping when using Paste and "Expand Canvas"
Intel-based GPUs now default to having hardware acceleration disabled. You may still force it to be enabled from the Settings dialog.
When pasting, the PNG format now has a higher priority than CF_DIB, which allows easier access to transparency (alpha) from other applications
Tools no longer incorrectly commit when clicking on the currently active layer in the Layers window
The layer's opacity was being ignored while drawing if it was the lowest (index zero) layer
You can now copy a file from File Explorer and Paste it into Paint.NET (regression from 3.5)
Fixed the canvas scroll bars occasionally being incorrect after maximizing the main window and then restoring it
Fixed radio button group tab processing
Fixed many small miscellaneous crashes
