Image Catalyst v2.3

=======================

For latest version link see http://x128.ho.ua/update.ini See http://rghost.ru/51256939 - for version 2.3 from 28.12.2014
This utils pack distributed AS IS. To see certain licenses or manuals see utilities official sites.

Pack of Windows utils to optimize (lossless compression) graphic files (JPEG and PNG formats). Using it is as good practice if you work with web page graphics (sprites and stand alone files).

Manual:

You can add files for optimization queue this ways:
- start "Image Catalyst.bat" and with «File browser» dialog choose graphic files;
- dragndrop selected files and/or folders on "Image Catalyst.bat" shortcut;
- run "Image Catalyst.bat" with full path folder with graphic files (by default program process all sub-folders).
Then select output folder for optimized files (program retain existing folder structure). You can use «overwrite» mode by pressing Cancel button in «Output folder selection» dialog (in this case all original files will be overwritten with optimized ones).
By default for PNG optimization multithreading is used (see config.ini to change this).
You can change base setting of project by edit Tools\config.ini file with any text editor.
You can not use special symbols like &, ^, % (, ), ! in file names or paths.

Types of PNG files:

Non-interlaced - standard mode.
Interlaced - interlacing is a trade-off: it dramatically speeds up early rendering of large files (improves latency), but may increase file size (decrease throughput) for little gain, particularly for small files.

Optimization modes for PNG:

Non-interlaced - standard mode. Continuous PNG loading;
Interlaced - uses «progressive loading» mode. And better user experience on slow connection or big data;
Default - optimized file and leave original mode intact.

Structure of PNG:

Types of JPEG files:

Optimize - better optimized JPEG file. Browsers loading it continuously, while loading.
Progressive - format, in which data is compressed in multiple passes of progressively higher detail. This is ideal for large images that will be displayed while downloading over a slow connection, allowing a reasonable preview after receiving only a portion of the data.

Optimization modes for JPEG:

Optimize - using Optimize mode;
Progressive - using Progressive mode;
Maximum - both optimize and progressive had made and used smaller one;
Default - optimize size but leave intact original image mode.
