Vectoraster是一款Mac上的一款用于创建基于矢量图的栅格图案以及基于位图图像的半调图的工具，支持导出为EPS、PDF、TIFF等格式，非常实用的一款图像处理工具。


ectoraster is a graphics utility for creating vector raster patterns and halftones based on images or gradients.
Hatch patterns and dot shapes can be changed and varied over the pattern to produce many different styles. The resulting raster always displayed and updated in real time as it changes parameters. The result can be easily exported as vectors to EPS or PDF files, such as images to JPEG, PNG or TIFF, or just copy and paste into most graphics software.
Features
Points
Many types of forms of different points, including circles, polygons, font characters and images or custom forms of imported vectors.
Detailed control of how you want the dot shape, and color transformation on the raster vary.
Base how the halftone dots vary in the source images, gradients defining live Vectoraster or a combination.
Advanced mode frame line with variable width lines instead of points.
Patterns
Many different frame patterns with detailed control over how points are placed.
Turn and easily move the raster pattern and add multiple distortions as randomness, waves and twists.
Vary the strength of distortions frame using source images and gradients.
Output
Copy the output of the frame and paste it directly into most vector graphics programs.
Export files to EPS and PDF output vector and JPEG, PNG and TIFF for bitmap.
Export data points (location and size) to a CSV file for most CAD or other processing.
