Display the Edit Brush screen and select the image name from the Bitmap drop-down box:

Note the following:

Make sure the image resolution is appropriate for the (X gap, Y gap) size. Otherwise the bitmap pixels will be too big or too small and the bitmaps will not draw.

Make sure the Fill drop-down box is set to Pattern.
If hatching is required tick set the X gap and Y gap values and the Angle value. Tick the appropriate Hatch boxes.
When a bitmap is used the Angle option only affects the hatch angle, the bitmap is not rotated.

Note: This must be a bitmap image, image formats such as JPEG, PNG, etc. are not suitable.
