- gradient - values '1' or 'true', specifies if plugin should be used.
- gmode - values 'r' for radial gradient or omitted for linear.
- gstart - values x or x,y (0 - 100)(percent of image width/height), start position of gradient (can be lower than 0 and higher than 100)(default 0,0 for l-gradient 50,50 for r-gradient).
- gend - values x or x,y (0 - 100), end position of gradient (default 0,100 for l-gradient 100,100 for r-gradient)
- gcstart - gradient start color, hexadecimal color value (argb shorthand f000 or full ff000000 are accepted)(default 0000).
- gcend - gradient end color, hexadecimal color value (argb shorthand f000 or full ff000000 are accepted)(default f000).
- gcfill - applies a fill color beneath gradient, hexadecimal color value (argb shorthand f000 or full ff000000 are accepted)(default f000).
- gclamp - center clamping (useful for r-gradients), amount the center value should be pushed outwards (0-100 percent from start to end)(default 0).
- gmirror - values '1' or 'true', specifies if wrapping of gradient should be mirrored (default is to clamp start/end).
