I use an hp multifunction scanner. i scanned it in at 300dpi. The size of the material is well over 3000pixels and over 25mb. i well look for these filters your are talking about. i use photoshop 6 and paintshop pro 7. paintshop pro7 has a seamless tile maker but it fades the edges or distorts them and makes the tiles look really bad also when there are patterns on them.
