The site is super - Google Translate is almost as cool.

Since my wife is Chinese she will love the stuff I can do with patterns from this site. I bet stuff like this will really get people using their machines.

Thanks, Alan

I love this site! Here is a Chinese rose I made from a grey scale on the site.

tips on smoothing out those grey scales:
load into photoshop or whatever.
set to greyscale and 16 bits
set resolution to 128 pixels/inch
set longest dimension to 2000 pixels
use filter "despeckle" a couple of time. that removes the "jpg artifacts" that causes those annoying little bumps along edges with high contrast.
save as .png
you are ready to import into designer.

So far, I'm at page 71 with over 900 pic saved...

There are many different ways to smooth out an image for import. And here is my take on it: http://patternhelp.com/uploads/HeightMapTutorial8.pdf

Blurring smoothes things out but may leave stepping on areas with low contrast, but adding a little contrast by adding noise before blurring allows one to be able to blur less, thus allowing for less rounding of high contrast areas.

Thanks Alan for the tip, nice work!

Here is a couple of carve from those greyscales, done in MDF. The one on the left has one coat of white shellac, the other is plain right after 3h30 carve time at best setting. both are 14" X 14". Carving depth is 1/4".

Great job! Question for you, I noticed on the images there's text on the bottoms of some that are in the image.
How did you work around this

Thanks,

Most of them I just crop out if they are outside the main subject. Some I use either photoshop to erase or Artcam to carve out. Other chinese website have much more pervasive watermark all over the picture, effectively rendering useless. Hope this website doesn't change it's policy about watermarks.

I'm guessing that the images are copyright and are only for a example of the 24 bit PNG's that you would normally buy from the site!
