Gigapixel AI Mac Installer

Gigapixel AI Windows Installer

v 4.4.4
October 22, 2019

Fix:

  • Fixed an issue that caused Gigapixel AI to crash with face detection turned on.
  • Fixed an issue that caused Gigapixel AI to crash if more than 508 images were processed in batch.
  • Fixed an issue that caused Gigapixel AI to crash if the file name or path contained non-Latin characters.
  • Fixed an issue that prevented the in-app updater to run.
  • Fixed an issue that caused Gigapixel AI to ignore the file's orientation metadata.

v 4.4.3
September 27, 2019

Fix:

  • Fixed Error 99 when checking for software updates.

v 4.4.2
September 23, 2019

Fix:

  • Fixed metadata issue causing jpeg and tiff to display with wrong PPI.
  • Fixed issue causing Gigapixel to not launch for some Mac users

v 4.4.1
September 12, 2019

Change:

  • Refined the advanced preference information

Fix:

  • Fixed the launching failure issue. Now Gigapixel AI can launch correctly on computers with CPUs before Intel 6th generation.
  • Refined crashes due to Intel Optimization (OpenVino). Now whenever Gigapixel AI crashes due to Intel Optimization, it will remember it and disable the Intel Optimization setting in advanced preference. Users can enable it manually by clicking the "Reset" button.
  • Fixed the "hddlapi.dll" missing issue.

v 4.4.0
September 3, 2019

New:

  • Intel devices optimization: Now a new option “Intel optimization” is in advanced preferences. If you choose “Yes”, it will optimize 6th-10th generation Intel CPUs and Intel iGPUs for Gigapixel. Typically, it will make Gigapixel run *3-5 times faster*than the previous “CPU” mode. But we cannot guarantee if it can work for CPUs from other vendors (e.g., AMD) or any Intel CPUs before 5th generation. If you still have very high performance desktop GPUs (e.g., NVIDIA 1080), “Enable dedicated GPU” (Yes) option will be the best choice. However, if you have relatively better Intel CPUs or Intel iGPUs than low performance GPU, you will see faster performance on Intel optimization (Yes) option.
  • Automatic detection for the best devices choice: Now you do not have to choose between GPU/CPU or enable/disable Intel optimization manually. Gigapixel will automatically run a benchmark and choose the best advanced preferences settings for you to achieve the highest speed on your computer. The benchmark will only be triggered once when you process the first image. Thus, the first image will take longer time than usual.

Change:

  • Refined the preview navigation panel
  • changed output file name extension to -gigapixel

Fix:

  • 8/16 Bit crash

v 4.3.1
August 15, 2019

  • Revised logic that affects how JPG/JPEG and TIF/TIFF files are saved to disk and how metadata is transferred from the source file to the output file
  • Revised message box dialogs throughout the application. This unifies the look and feel across platforms

  • When on the 'Resize By Scale' tab, when scaling to a custom value, the label now reads: "Custom Scale (0.20 to 6.00)"

  • MacOS: Users of 10.14 Mojave may have missing or unreadable buttons on the Trial Expired or Start Trial dialog message boxes.

  • In the file processing list, the color profile is detected and displayed next to the resolution for the input side. As you change options in the right panel, the output color profile will be updated. By default, RAW images will be processed as JPG images, maximum quality, ProPhoto RGB color profile.

Changes:

Fixes:

  • The selection of color profile (or desire to keep the color profile) was not being consistently applied to images.
