Pointillizer is an extension for CorelDRAW that lets you create high-quality vector mosaics from any number of selected vector or bitmap objects. Whether you are looking to create precise halftone patterns or artistic effects that resemble pointillistic art, this extension will give you the inspiration and tools you need to create striking designs.
A vector mosaic created with Pointillizer
Vector mosaics created with Pointillizer are ideal for vehicle wraps and window decor projects. You can fine-tune your designs to perfection by using an array of controls.
After you download Pointillizer, it automatically appears under the Effects menu in CorelDRAW.
You can create vector mosaics from vector objects or bitmaps.
1 In CorelDRAW, select an object.
You can also select multiple objects or groups of objects.
2 Click Effects 
Pointillizer.
3 In the Pointillizer docker, adjust any settings you want.
4 Click Apply.
If you want to cancel the rendering process, press Esc.
Use any of the following controls to customize and fine-tune your vector mosaic.
Density
This control lets you adjust the number of tiles per square inch.
 Density value of 5 |  Density value of 10 |  Density value of 18 |
Scale
This control lets you adjust the size of all tiles by scaling them up or down. Values higher than the default value of 1 increase the tile size; values lower than 1 decrease the size.
 Scale value of 1 |  Scale value of 1. 2 |  Scale value of 0.8 |
Screen angle
Use this control to rotate each row of tiles about the horizontal axis by the angle you specify. Positive values rotate the rows counterclockwise.
 Screen angle of 0º |  Screen angle of 30º |  Screen angle of -30º |
Keep original
When you enable the Keep original check box, the source graphic is preserved, and the vector mosaic (output) is placed on top. Disable the check box to have the source deleted automatically after the mosaic is created.
Limit colors
Enable this check box to control the number of colors that are used for rendering the mosaic. To specify the maximum number of colors in the output, type a value in the Number box.
 Source (original) |  With the Limit color check box disabled |  Limiting colors to maximum of 8 |
Tracing options
Choose from a selection of tracing algorithms to customize the mosaic.
Method lets you choose a technique for interpreting the source graphic. Three tracing methods are available — Uniform (white matte), Size modulation 1 (opacity), and Size modulation 2 (luminosity).
• Uniform (white matte) uses tiles of the same size to generate the mosaic. Transparencies are flattened against a white background.
• Size modulation 1 (opacity) interprets the source as a series of tiles that vary in size based sampled opacity values. The more opaque (less transparent) the areas are, the bigger the tiles are.
• Size modulation 2 (luminosity) interprets the source graphic based on its brightness values. Brighter areas in the source are rendered as smaller tiles; darker areas are rendered as bigger tiles.

Merge adjacent lets you specify the maximum number of tiles of similar color to be combined into a single tile. This setting has effect only if there is enough space available.
 Original |  Maximum number of 1 |  Maximum number of 5 |
Weld adjacent lets you weld together overlapping tiles. Enable this check box to render the output in clusters of color; disable the check box to preserve more details.
 Original |  Welding enabled |  Welding disabled |
Shape
The Shape list box lets you pick one of the preset tile shapes such as a circle or square. To use a custom tile shape, do the following:
1 Choose Custom from the Shape list box.
2 Click Select at the bottom of the Preview area.
3 Click a closed curve in the drawing window.
The Preview area shows the selected tile shape.
