ELC - Error Level Comparer
A quick Windows GUI application to visually display the error level factor caused by jpeg lossy image compression to a known quality percentage.
Usage
ELC inputs a JPG image file, saves an intermediate JPG at the compression level you specify, then processes the difference into a bitmap image.
Features
- Adjustable JPG compression quality percent
- Preview and bitmap output
- Scaling adjustment to highlight compression error positions
- Noise dropping (squelch), to set a lower bounds of error level to ignore
Notes
Only allows input of JPG files currently. An intermediate file, being the JPG at the specified compression level, is saved in the same name and path as the input JPG, but with the '.intermediate' extention.
