PostScript Path Combine -

-

i have begun learning postscript in order produce graphics latex , have no idea how combine path stroke affect outer border of drawn shape. code follows:

/black { 0 0 0 1 setcmykcolor } def /gold { 0.02 0.17 0.72 0.05 setcmykcolor } def newpath   % center 1/2w , 1/2h   /cx { 1200 2.0 div } def % center-x   /cy {  600 2.0 div } def % center-y   /r  {  600 9.0 div                4 mul              2.0 div } def % star's radius   cx r   0 cos mul add   cy r   0 sin mul add moveto   cx r 144 cos mul add   cy r 144 sin mul add lineto   cx r 288 cos mul add   cy r 288 sin mul add lineto   cx r  72 cos mul add   cy r  72 sin mul add lineto   cx r 216 cos mul add   cy r 216 sin mul add lineto closepath gsave gold fill grestore 1 setlinewidth black stroke

when stroke drawn, lines crossing shape drawn. know if there way have outer border of shape stricken , not inner lines. rather not have calculate lines forming star intersect, i.e. keep 5 lines instead of getting 10 smaller ones.

note also, learning ps as-is , not wanting use external programs (read illustrator , like). purpose of question built knowledge of postscript.

simplest stroke first , fill. may want double linewidth doing cuts lines in half.

%... closepath gsave   2 setlinewidth   black stroke grestore gold fill

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
