I am using Canvas X Pro 16 again after a couple of years away and I'm struggling to remember how to make custom pattern fills. I'm trying to make pattern fills for terrain types (e.g. mountains, hills and swamp) but all the standard fills are much too fine and dense for what I want.
I seem to recall having done this in the past from a jpeg image that I scanned but I can't figure out how as the pattern manager doesn't seem to work that way--it seems to want me to pick a pen and ink and pattern from a bunch of presets.. It's possible that I did it with an earlier of canvas but presumably that kind of functionality hasn't disappeared.. Honestly, if I could just get it to fill polygons with decent sized (say 8 point) inverted "v"s with some space between them for mountains that would be and rotated "C's) for hills that would be great. Can anybody sugest how I can do this?

If you are inquiring about the pattern inks in the Ink tab of the Attributes palette, then that functionality has not changed since the earliest versions of Canvas in the late-1980s. When you go to pattern inks you should see the cursor become a pencil when you hover over the pattern well; the pattern well is where you see the pixels that create the pattern. You can see the custom pattern I just created below.
Whatever default pattern is the default when you go to the Pattern manager can be quickly erased by sliding the Grayscale slider to the right and then back to 0. When you have the pattern you desire, you can then save it by clicking Add Preset..
The issue with using pre-defined or custom patterns is that they are restricted to an 8 × 8 grid. While that adequate 30+ years ago, it results in imperceivable patterns on modern computers that support much higher resolution and color palettes than was possible in the late-1980s.
What you mentioned about using an image to create a pattern is more likely to be a texture ink. Ideally, if you are using symbolic patterns, then creating a custom hatching ink would serve to better, particularly as hatches are vector patterns, and therefore, resolution independent.
You are a bit behind having Canvas X 16. I tested this in Canvas X 2019 and Canvas Draw 6, but Canvas GFX still has the Canvas X 16 Product Support and Resources available online. Select Canvas X Help to go to the interactive User Guide, then search for the following topics:
John, to follow up on Michael Dawson's excellent response here is a procedure I wrote for myself to achieve what you are trying to do:
I have used this method with Canvas 11, 12 and 14 in Windows XP and now Windows 7 x64 with gif, pdf, bmp and cvx patterns.
Just checked the method in Canvas X GIS 2018 under Windows 10 x64 - still works.
Thanks so much for your responses. This should get me working again.
