c# - get only 1 pixel's color from a texture2D -



c# - get only 1 pixel's color from a texture2D -

currently, i'm using method pixels' color of texture2d

color[] pixelcolours = new color[mytexture.width*mytexture.height]; mytexture.getdata<color>(pixelcolours); as can see, store every pixels' color in tab. the texture2d pretty huge : 1000 pixels x 1000 pixels. but need 1 pixel's color, means store 999.999 useless others pixels. the pixel's position on texture2d moving, code in update() method.

are there others ways 1 pixel fast low memory cost ?

the getdata method overloaded , allows specify starting pixel , how many elements get: http://msdn.microsoft.com/en-us/library/bb197093.aspx.

c# colors xna texture2d

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
