About UVtools

MSLA/DLP, file analysis, calibration, repair, conversion and manipulation

What's new in 7.1.2

- (Improvement) Linux: Present better error messages when libcvextern fails to load, and add a check for missing dependencies
- (Fix) Linux: libcvextern no longer requires the system libtiff.so.5 and libsqlite3, fixing startup on Debian 13 and Ubuntu 24.04+ (#1161)
- (Fix) macOS: The missing dependencies window never listed the libcvextern dependencies
- (Fix) Repair layers: Attach islands could hang forever on files with cloned layers, such as from timelapse, clone
layers, double exposure, lithophane, stir resin and the calibration tests, as the clones shared the same lock
- (Fix) Issues: Resin traps, suction cups and print height issues on a single layer had their area calculated as a
volume, multiplied by the layer height in pixels
- (Fix) Issues: Ignoring an island also ignored the islands with the same pixels on other layers
