Update of SLM Slideshow Player (Version 2.3.5)

Download the latest version of the HOLOEYE SLM Slideshow Player Software. This version brings new features, bug fixes, and stability improvements, including a more reliable playback rate control.

The up-to-date version can be downloaded through our download website at https://customers.holoeye.com . The following features and fixes are included in the new 2.3.5 version:

New Features

  • Added a new “Rendered Output” capture mode to the SLM preview window, which displays the renderer’s output signal directly instead of capturing the operating system screen.

Bug fixes

  • Updated the internally used HDF5 library from version 2.1.1 to the currently maintained version 2.2.0 (security maintenance / EU Cyber Resilience Act compliance). Reading existing .h5 files (e.g. wavefront compensation files) remains fully backward compatible.
  • Improved the SDK process executable lookup.
  • Fixed the playback rate spin box:
    • the arrows no longer stop working at low frequencies
    • out-of-range input is clamped instead of silently reverted
    • switching between Hz/ms/Frames keeps the configured value.
  • Playback rate: frequencies are shown with 4 decimals, the arrows gray out at their limits, and the speed controls keep a stable width when switching units.
  • Edit Slideshow dialog: playback rate changes are no longer discarded when confirming with OK.
  • Pressing Enter in an input field of the Edit Slideshow and Optical Setup dialogs no longer triggers a button unintentionally.
  • Fixed the initial playback rate: a unit mix-up set an arbitrary startup value.The startup state and newly created slideshows now default to 2 Hz.
