Generating a Pattern in Photoshop

To create a pattern using this filter, just follow these steps:
1. To apply a pattern to an existing image, first make a copy of the layer that contains the image area you want to convert to a pattern.
To apply the pattern to a new image, select the area you want to use with the Rectangular Marquee tool and choose Edit➪Copy. Then choose File➪New, choose Custom from the New File dialog box, click OK to create the new file, and paste the selection into the new image.
2. Choose Filter➪Pattern Maker.
3. Select the area to be used as the basis for the pattern.
4. If you’re creating the pattern in the current layer, choose the Rectangular Marquee tool from the dialog box’s Tools palette, and select the portion of the image you want to convert to a pattern.
You can drag the selection marquee around the image, use the zoom features to change the magnification, or drag the image around by using the Hand tool.
5. If you want to completely fill the layer with tiled versions of the pattern, specify the size of the tile by typing values in the Width and Height boxes in the Tile Generation area. You can also enter the offset (None, Horizontal, or Vertical) to use and the amount of that offset. If you’d rather have only a single, non-tiled image, click the Use Image Size button.
6. Set other options:
- Smoothness: Set a value to determine how smooth the edges of the patterns are blended with the surrounding tiles.
- Sample Detail: This parameter controls the maximum size of details in the pattern.
- Preview: Choose whether to display the original image or the generated patterns in the preview window.
- Tile Boundaries: If you want, you can insert a line between tiled images to show their boundaries.
Select the Tile Boundaries option and, if you like, choose a color for the boundary that will show up well against your sampled image.
7. Click the Generate button to create a pattern from your selection. You can click the button multiple times to create multiple pattern variations.
Photoshop displays all the different patterns you generate in the Tile History panel in the lower-right corner of the dialog box.
You can review patterns in a slide-show manner by clicking the Previous, Next, First, and Last arrows.
8. If you see a pattern you want to save, click the floppy disk icon at the bottom-left edge of the Tile History panel.
9. You can get rid of patterns that you don’t like by selecting them and then double-clicking the trash can icon in the lower-right edge.
Tile History can save up to 20 generated patterns.
10. Click OK when you’ve saved all the patterns you want to reuse.
