Hatch fill patterns plus Color & Invert

Updated code hatch with color and inverted hatches

Description

This is an update of Brian Katz's update to Ben Hinkle's original applypatch and makepatch code for replacing colors in figures with hatches as well as David's applypatch_plus. This new version allows you to either make a black and white hatch or use the colors of the fill to create colored hatches. Additionally you can invert the hatch, i.e. it is possible to have a blue hatch with white background or a white hatch with blue background. All of the previous work done in the plus addition should still work, just these are now new options. See help of functions for example usage.

It's helpful to me. It's works.

Hi,

I tried it with bar but i am having problem with resizing the image. If i keep the image at a very large size then lines are visible but if i resize the image to a relatively smaller size, lines change and eventually become garbage. It is quite sensitive to size change, and even i don't know what is the best size of the figure at which it works. It also is overwriting the bar borders so some sides get disappear. Would you please tell if it is possible to keep the hatch in the bar as well as to resize figure so that it fits the paper? Lines in the bar move as i resize the image. What is the best size at which it works?

It is very good and helpful for my work!

I tried to embed the hatched figures in postscript (ps) http://www.cs.wayne.edu/xliu/imgs/ps.jpg, but they look much worse than in pdf http://www.cs.wayne.edu/xliu/imgs/pdf.jpg. Do you know how I can fix this issue?

Does just what I was looking for!

Bug Report :
the image generated has twice the number of rows, and columns (thus 4 times the weight) than expected by the defined size and image position.
as a result, Fonts in the result files are half the desired size. See at the end of my comment a file that demonstrates this bug.

Other comments :
This is a convenient workaround to create hatched graphichs.
input is a color graphic (either a matalb figure or an image file).
Output is a hatched graphic where each color area was changed into hatches.

I do not feel comfortable with the last two parameters (scales) because they are relative. Absolute line width and spacing would be better imho (perhaps this is possible and I missed something).
