PolarPixellate and MosaicBlur filters were implemented in JNI but inaccessible via rule strings. Users had no way to discover or apply these effects through the filter string API.

Changes

Parser additions (cgeDataParsingEngine.cpp):

• Added polarpixellate to advancedStyleParser:
  • @style polarpixellate <pixelSizeX>,<pixelSizeY> (uses default center 0.5,0.5)
  • @style polarpixellate <centerX>,<centerY>,<pixelSizeX>,<pixelSizeY> (custom center)
• Added mosaic to blurParser:
  • @blur mosaic <blurPixels> (blurPixels >= 1.0)

Documentation (README.md):

• Added "Common Filter Examples" section with syntax and parameter ranges
• Documented MotionFlow (@dynamic mf) for completeness

Usage

// Mosaic blur
String rule = "@blur mosaic 10.0";

// Polar pixellate with default center
String rule = "@style polarpixellate 0.05,0.05";

// Polar pixellate with custom center
String rule = "@style polarpixellate 0.3,0.7,0.08,0.08";

// Combine filters
String rule = "@blur mosaic 10.0 @adjust brightness 0.2";

Bitmap result = CGENativeLibrary.filterImage_MultipleEffects(srcBitmap, rule, 1.0f);

• Fixes Rule string for filters not shown in cge-tools #423
