Symmetrical Pattern Generator

Overview

The Symmetrical Pattern Generator creates randomly positioned DIV elements on a 200px by 200px canvas in the upper left quadrant and then mirrors them in the other three quadrants to create a pattern.

To generate a pattern, simpy press the "Ok" button. You may also customize the patterns look by tweaking the settings. Read on for detailed info.

How to use it

It's really pretty simple. Here's an overview of what the controls do:

Persist Pattern: If you see a pattern you find interesting, but want to adjust its appearence, check this box. When the box is checked, the application will not generate a new pattern when you click the "Ok" button, rather it will apply the settings to the existing pattern.
Pixel Size: Sets the dimensions of the pixels.
Pixels Per Quadrant: Sets how many pixels are rendered in each quadrant. If you specify 15 pixels, your pattern will have a total of 60 pixels. This setting is ignored when "Persist Pattern" is checked.
Pixel Resizing Options

Pixel Sizes Constant: Default value. All pixels in the pattern will be the size specified by "Pixel Size".
Decrease Pixel Size on Radial Distance: Pixels close to the origin of the canvas will be the size specified by "Pixel Size". The further they are from the center, the smaller they become.
Increase Pixel Size on Radial Distance: Pixels close to the origin of the canvas will be small. The close the pixel is to the edge of the canvas, the closer to the value of "Pixel Size" it will be.

Pixel Borders: Check this box to render the pixels with borders. Uncheck it to render without.
Color Modifier: This is used to change the hue of the randomly generated pixel colors. It alters the Red, Green or Blue channel of the pixel, depending on which color is dominant or which Color Channel is selected. It must be a valid Hex value from 00 to FF.
Apply Modifier To: Select the color channel to apply the value of "Color Modifier" to.
Brightness: Controls the saturation of the pixel colors. The higher the number, the lighter they will be when "color modifier" is set to FF. The results of this setting vary based on the value of "color modifer".
Border Color: The color of the pixel borders. Must be a valid Hex value in this format: #RRGGBB. Ignored when "Pixel Border" is unchecked.
Background Color: The color of the canvas. Must be a valid Hex value in this format: #RRGGBB. Ignored unless the "Overylay On" option is set to "none".
Overlay On: This option allows you to overlay your pattern on an existing pattern from the Pattern Gallery.

When you are satisfied with your pattern, you may submit it to the Pattern Gallery by hitting the "create image" button. This also allows you to build another layer on top of your pattern by using it as the "Overlay On" option.
