Some useful hints
Create pattern on larger image and then cut out a portion of that image and
then apply the last filter touch on the portion of that image.
You can create a pattern on larger image and then resize that image to obtain some
additional effects.
When blured brushes are used, you'll have to cut a small amount of margins
(ImgCtrl->Canvas->Cut Margins)
or use some filter to get seamless pattern, because of blured brush behaviour on image borders.
Try to awoid tilling of large images for background pattern of your web pages. Smaller the
background image, faster the loading time.

Creating seamless patterns
Seamless patterns are very useful for web backgrounds. In order to obtain an image
that can be tilled as background, we must prepare our image in such a way that border
pixels wraps to each other.
In this way, we get an image that is "borderless".
We can do it by applying any filters (Filters 3x3 or IPL filters) with Wrap option checked.
Also, we can create patterns with free hand drawing and retouching with Wrap FH
option checked.
In this way, drawing outside an image is wrapped to the opositi side
of image.
We can also apply some other actions (warping, shifting), but we must apply some wrapped filter
after those actions to obtain seamless pattern effect.
Noisy Patterns
These are steps needed to create noisy pattern:
- Creat the new image with any color desired. This color does not have any
effect in further steps, so you can simply choose white background.
- Select foreground color that will be dominant color of your pattern.
- Open Transparency & Channels of interest dialog, and set
PixelVary slider to desired amount. The higher amount will introduce the
higher noise in your image.
- Select Draw action with normal mode and apply foreground
color on complete image (apply button).
- Reset PixelVary to 0 if you don't want to apply noise in further actions.
You have created a noisy image which consist of foreground color pixels varied by an amount
specified in step 3. This is starting point for some seamless patterns.
We will simply name this starting image as noisy image.
Median cut
This filter is very useful for obtaining some simple but effective seamless patterns.
Start with some noisy imageand set PixelVary slider to some amount in order to
introduce some noise after median cut. In this way we can repeat median action on and on and
our pattern changes every time.
If you set PixelVary amount to 0 median cut
will stop after two or three steps and image will not change any more. This can be used
to obtain very soft backgrounds. You can combine median action with various PixelVary
amounts. Also, you can play with various size of median kernel, from 3x3 to 9x9 or higher.
Using other filters
Beside median cut, you can use sharpening, bluring, erode, dilate or your own convolvers.
The best way is to try filters and to see what is the best solution for your pattern. Creating patterns is
a process of dicovering and trying. For simple test, start always with noisy image.
Warping
Warping actions (especially ripples method) are also useful for patterns creation.
Start from some noisy image, go to Warp action, select Ripples method with or
without antialiasing and apply ripples effect few times on image. You'll get
a marble-looking pattern. To obtain seamless pattern, use some wrapped filter after this action
(median 3x3 or sharpen 3x3).
Drawing and Retouching
Using free hand drawing and some retouching action can create very interesting patterns.
The best way is to perform simple normal drawing with Wrap FH option checked, or
using free hand Spread methodon some noisy image. You can set PixelVary
amount to 0 or set some small amount of noise in order to obtain a dusty pattern.
Pixels shifting
Pixels shift action (especially intensity and bumping) can also be used to obtain
nice patterns. Create noisy image and shift it few times with some method.
You can use shift action in combination with various filters.
You can also play with direction of shifting as well.
Set PixelVary amount to 0 while applying shift action.
Note!
You'll notice that these background patterns have "screaming" colors. These examples are used only
to present possibilities of various actions in creating seamless patterns, not as a gallery of backgrounds.
