Dear Mr. Liu: about the moiré patterns of halftoning images.

[audo23]

Dear Mr. Liu: I am a fan of your github. They inspires me very much..Thank you! now I have a little question: after trying: https://github.com/yunfuliu/pixkit/tree/master/modules/pixkit-image/src,  with DirectBinarySearch, ErrorDiffusion, I found that the result printed halftoning picture has kind of moire pattern.  What I used for printing the result halftoning images is a 200dpi, thermal paper printer, the printed pictures are like these:   you can see there are lines across the human, which I think is moire pattern. The 200 dpi can not be changed, so would you please give me some guidance about how to remove the moire pattern, or improve the output image? thank you!Jack D.
