v1.6.10-beta-free

• Added: 3 New Streamlines PFMS Streamline PFMs generate streamlines to represent an image which are driven by the direction from a vector field. The streamlines are spaced according to the brightness of the image without overlapping. The underlying vector field can be altered dramatically to create many different styles which still remaining faithful to the original images brightness. This makes them very versatile for creating stylised wave like patterns which can be highly customised.

v1.6.6-beta-free

• Added: 2 New PFMs:
  • Sketch Flow Fields - Uses a Flow Field to direct the generated paths.
  • Sketch Superformula - Uses Superformula to produce sketch plots which are driven by radial patterns, such as stars, vortexes and ellipses. You can use examples shown on the Superformula wiki by using the examples m, n1, n2 and n3 for Frequency, Curvature, Sine Factor and Cos Factor respectively
• Added: CMYK (Extended Gamut) - A new color separation option which extends the stand CMYK range to include Orange, Green, Violet, Red and Blue. It can create plots with even more vibrant colors and more colour accurate result than standard CMYK. You can even add your own pens to the color separation, allowing for even more accurate results, it is best to still keep the main CMYK pens as part of the plot.
• Added: 2 New Distribution Types
  • Random Squiggles - Unlike the classic Random distribution, random squiggles will only change pen when a Squiggle (continuous path without pen lifts) is finished.

• Added: New CMYK Settings
  • Clean Black - Prevents areas of complete black being drawn over by non-black pens, resulting in a cleaner result with less ink wasted.
  • Clean White - Works in a similar way to Clean Black, and protects white areas from being drawn over by off-white pens.
  • Vibrancy - Controls the overall intensity for the Extended Gamut colors (Orange, Green, Violet, Red and Blue)
  • Reduce Overlay - Controls the amount pens are allowed to overlap in the final result.
