11 minutes to read

This topic includes new features, improvements, and bug fixes for the front-end lib of Design Atoms Framework 7.

7.1.64 - October 30, 2025

Colorize Algorithm Improvements

Implemented smart binary thresholding for better mask accuracy.
Added background detection and removal to prevent artifacts.
Boosted performance by ~1.3x with direct bitmap memory writing.
Fixed bugs in alpha contour extraction, minor optimizations, and refactoring for stability.

Bug Fixes

Fixed a problem with color management when there were SVG graphics in a colorless container.
Fixed a problem that caused an AccessViolationException when loading fonts using the FontProvider.

7.1.61 - September 25, 2025

Bug Fixes

Fixed an AccessViolationException that occurred during the rendering of templates with transparent backgrounds.

7.1.60 - September 12, 2025

Bug Fixes

Fixed a rounding error in the expand box overflow strategy, which caused some text to be clipped and not displayed.
Fixed a problem when incorrect DPI calculations for texture containers caused slow proof image rendering.

7.1.58 - August 25, 2025

General Improvements

Improved the algorithm to colorize images. Now, if you have inserted a vector image (PDF, SVG) into a placeholder with the colorize effect enabled, it remains vector after applying the effect. This effect will also maintain spot colors when recoloring.

7.1.56 - August 18, 2025

Bug Fixes

Fixed a problem with embedding images that have external links.
Fixed a problem with rendering previews of colorless containers.
Fixed a problem with rendering previews for remote source images.

Bug Fixes

Fixed a problem with missing DisplayName in PlaceholderItem.Content.

7.1.52 - July 21, 2025

General Improvements

Improved resource persistence in templates. External images referenced through URLs, paths to Asset Storage, and paths to private assets can now be embedded into state files for long-term data preservation using the EmbedProductImagesAsync() method. If an image becomes unavailable, it will be removed from the state. After invoking this method, save the updated state file.

Bug Fixes

Fixed a problem when an extra page was rendered when the background contained no design elements.

7.1.51 - July 16, 2025

Bug Fixes

Fixed rendering issues caused by empty or missing font size attributes in auto layouts.
