The brush sets often contain PNG images that can be used in many other applications such as PSP, Photo-Paint and GIMP. If the set does not contain the PNG images then you can always quickly create a new PNG by using the strokes in the ABR and creating a dab for export to a PNG image. The PNG images can be converted also to other formats so if you want JPG or TIFF then use a conversion tool such as irfanview (free tool) or PSP (trial can be found via the corel.com website).
You can find all our arrow brushes for use, they can be used in countless applications
Use the brushes to create pattern tiles or distortions in Adobe ® Photoshop ®
1) Select brush tool
2) Select color via toolbox / foreground color or perhaps via the swatches panel.
3) Apply dabs as required (avoiding the edges of the image)
4) Filter menu and Other menu and offset (set to 1/2 height and 1/2 width) to shift design for tile
5) Apply more dabs (again avoiding the edges of the image)
6) edit menu and define command
You can also use blending modes and opacity to create many variant tile designs. You can also create variant strokes by adding effects to the strokes and then re-defining the stroke and adding those to the image. In that way, you can add perhaps rough / distressed / blurred variants. You don't have to use the same stroke to define the artwork either, you can change the stroke by selecting different presets in the panel.
You don't have to create them in the traditional ways by using the define tile command. Instead the brushes can be applied to a huge document / image in a variety of ways to create a super large tile. By applying the strokes loosely across a grid, randomness can be generated in the tile. Another way to add randomness would be to use deco scripts (you can find them in the fill menu when selecting patterns) with the strokes derived tiles. You can also use the view show grid command to see a grid to use as a structure for the artwork.
The PNG images can be used as brushes and that was the primary purpose of the resource but they can also be used as tiles as well as textures and displacements. To use them as layers, simply open the PNG images and then go to the edit menu and define tile instead of define stroke command. They can then be used as a tile layer via the layer menu 'new fill layer'.
