Imagebrush resolution to render a MeshGeometry3D in WPF -


i visualizing spatial data using meshgeometry3d in wpf. noticed passing imagebrush constructor of diffusematerial makes 3d visualization , manipulation fast , efficient (than using visualbrush). solution in following code block this.datameshmodel geometrymodel3d includes mesh. problem have give high resolutions (1000) bitmap image source make grid nice , distinguishable. choosing high dpi seems odd , raises memory exceptions. suggestion? data model looks this 1000 dpi , this 4000 dpi. thanks!

    private void assigntexture(geometry gridgeom, double texturedpi, double gridthickness)     {         // rendering grid on drawingvisual         drawingvisual dv = new drawingvisual();         using (var dvc = dv.renderopen())         {             dvc.drawrectangle(brushes.tomato, null, gridgeom.bounds);             dvc.drawgeometry(null, new pen(brushes.black, gridthickness), gridgeom);         }         if (dv.drawing.canfreeze)         {             dv.drawing.freeze();         }         //rendering drawingvisual image         rect bounds = dv.contentbounds;         rendertargetbitmap renderedbitmap = new rendertargetbitmap(             (int)(bounds.width * this.texturedpi / 96),             (int)(bounds.height * this.texturedpi / 96),             this.texturedpi,             this.texturedpi,             pixelformats.pbgra32);         renderedbitmap.render(dv);         // adding rendered image create imagebrush         imagebrush imbrush = new imagebrush(renderedbitmap);         //creating material         diffusematerial datameshmaterial = new diffusematerial(imbrush);         this.datameshmodel.material = this.datameshmaterial;     }

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
