Build 29 - Video Upscaling!

Changes

• Added video upscaling via ESRGAN! Currently supports GIF and MP4 input and output.
• GUI improvements for DPI-scaled displays and small screens

Known Issues:

• Video Upscaling has not been tested with NCNN yet, might still work though
• Sidebars have some empty space if no scrollbar is shown

Build 28 - Model Chain Fix, More Padding Modes, UI Changes

Changes:

• The ESRGAN processing options (HR size, seamless mode, alpha) are now in the main UI, not only in the settings
• Added seamless/padding modes: Extend (stretches last pixel row on each side) and alpha (surrounds the image with transparency)
• Added buttons to reload the current image or open its source directory
• Some general UI changes in the main view
• Model Chaining on Joey's ESRGAN has been fixed, was broken in b27
• Copying the images for batch processing now shows a progress bar
• Added disk space check before batch processing

Build 27 - Portable Mode & No More Seams

Changes:

• Portable Mode - Stores all data in the same folder as the executable. Launch with argument -portable to use.
• Joey's ESRGAN has been updated and uses a better tiling/merging code that avoids seams and is faster (Thanks @joeyballentine)
• Manual image browser that can be opened by right-clicking the preview area (as an alternative to drag-n-drop, supports multiselect)
• Added option to use original scale or resized scale for comparisons (when pre-resizing is used) in the settings
• Important fixes to batch processing, avoids freezing
• Preview image size limit increase from 4096px to 8192px
• Internal improvements to Embedded Python installer, disk space check now works for any drive (for portable mode), more error handling

If you don't know how to start Cupscale with a command line argument, download CupscaleStartPortable.bat and put it in the same folder as Cupscale.exe, then launch it using that batch file.

Build 26

Changes:

• Added support for offline interpolation (creating new model files by interpolating them IEU-style)
• Replaced MessageBox popups with a custom, more flexible solution
• Comparisons now use the unscaled input image if pre-scaling is enabled
• Fixed bug in ImageSharp resizing code that broke model comparisons
• More error handling, more loading dialogs to avoid Cupscale appearing to be frozen

Build 25 [Hotfix 2]

Changes:

• Image resizing is now faster by using ImageSharp instad of Magick.NET for scaling
• Added support for MozJpeg, the world's best JPEG encoder (enabled by default)
• Fixed memory leak in VRAM monitoring code
• Fixed dependency checker not detecting system python dependencies correctly
• Improved dependency checker (now shows you which options you have with the current setup)
• Fixed esrgan-launcher not working with embedded python
• Added warning about drag-n-drop not working if launched as admin

Hotfix 1 Changes:

• Fixed DDS output mode
• Added tooltip to MozJpeg option to clarify what it does

Hotfix 2 Changes:

• Fixed problems with MozJpeg JPEG exporting
• Fixed a minor bug with Python detection in the Dependency Checker
• Uninstalling the embedded Python runtime now shows a loading dialog and will automatically switch back to system python

Build 24 [Hotfix 1]

Changes:

• Added support for an embedded Python runtime that includes all dependencies
• Added a tool that downloads and installs the embedded Python runtime automatically
• Added the "Dependency Checker" that will show which dependencies (Python, Torch, etc) were found

Hotfix 1 Changes:

• Added check for any GPU in Dependency Checker
• Fixed bug where installing embedded Python wouldn't enable it
• Fixed error when opening the dependency checker in the initial setup

Build 23 [Hotfix 1]

Changes:

• New Debugging Options: Extended logging, ESRGAN CMD window can be shown
• Much cleaner logging, log is now easier to read and less cluttered
• Improved color depth detection
• Fixed bug where the DPI scaling would break when an image gets loaded
• Error Handling improvements
• Added donation button

Hotfix 1 - Additional Changes:

• Improvements to batch post-processing queue (if a file is locked, retry instead of throwing an error)
• Fixed bug/flaw with batch post-processing when using esrgan-launcher

Build 22

Changes:

• Updated Joey's ESRGAN (this should fix bugs with small images and improves tiling)
• Improved color format conversion for 8-bit (and other low bit depths) for PNGs
• Other minor changes

Build 21 [Final]

Changes:

• Added model comparison tool to compare several models applied to a single image [Experimental]
• Added benchmark timer for upscaling
• Added "Open Model Folder" button
• Settings now open automatically when the user needs to set a model path
• Fixed Ctrl+V in batch processing out path triggering the previre image pasting
• Some UI improvements

Pre-Release 2 Changes:

• Fixed alpha issues for PNGs with non-standard color depths
• Fixed post-processing problems
• Fixed issue where the model comparison would be vertical if using "only models" composition mode

Pre-Release 3 Changes:

• Fixed ESRGAN crashing during batch upscaling
• Fixed reizing after upscaling not working

Pre-Release 4 Changes:

• Added option to disable pre-processing for batch upscaling
• Added option to flip TGA images during import
• Fixed non-PNG depth detection
• Added folder browser dialog to batch upscale output folder textbox
• Better folder browser dialogs
• Updated py scripts to avoid errors

Final Release Changes:

• Fixed post-processing queue problems when using overwrite mode

Build 20 Hotfix 1

Changes:

• Fixed comparisons not working correctly
• Fixed image import for 8-bit PNG images while Alpha is enabled
