Vectoraster 7.4.6

Vectoraster is a graphics utility for creating vector-based raster patterns and halftones based on images or gradients. The raster patterns and point shapes can be changed and varied across the pattern to produce many different styles. The resulting raster is always shown, updating in real time as you change parameters. The result can then easily be exported as vectors to EPS or PDF files, as images to JPEG, PNG or TIFF, or simply copied and pasted into most graphics software.

You can download and try Vectoraster for free, but with some limitations. To remove these limitations and get the full version you have to pay for the application.

Features
General
Many different point shape types, including circles, polygons, font characters and imported custom vector shapes or images
Detailed control of how you want point shape, transformation and color to vary over the raster
Base how the raster points vary on source images, gradients you define live in Vectoraster, or a combination
Advanced line-raster mode with lines of varying width instead of points

Patterns
Many different raster patterns with detailed control of how the points are placed.
Easily rotate and offset the raster pattern, and add multiple distrotions like waves and twists.

Output
Copy raster output and paste it straight into most vector graphics software.
File export to EPS and PDF for vector output, and JPEG, PNG and TIFF for bitmap.
Export point data (location and size) to a CSV file for further CAD or other processing.
