i'm working on program in python packages numpy,scipy , matplotlib.pyplot. code: import matplotlib.pyplot plt scipy import misc im=misc.imread("photosafteraverage/exampleafteraverage1.jpg") plt.imshow(im, cmap=plt.cm.gray) for reason image isn't showing (checked if got image, in part it's fine- can print array.). you need call plt.show() display image. or use ipython --pylab interactive shell matplotlib aware.

i confused use of boost::ref. dont understand why 1 want following - void f(int x) { cout << x<<endl; x++; } int main(int argc, char *argv[]) { int aaa=2; f(boost::ref(aaa)); cout << aaa<<endl; exit(0); } what use of passing ref function. can pass value instead. not ref passed. in above value of aaa in main remains 2 only. where boost ref useful? is possible use boost::ref in scenario. want pass iterator refernce std::sort function. sort works on iterator copies - boost::ref make work references also? (without changes std::sort) i dont understand why 1 want following they wouldn't. that's not boost::ref (or these days std::ref ) for. if function takes argument value, there's no way force take reference instead. where boost ref useful? it can used make function template act if takes argument reference, instantiating template reference (wrapper) type, rather value type: template <typen...

how can set binding dependency property belongs drawingvisual element in code ? for dependency property belongs frameworkelement have called elem.setbinding(...) not have function in drawingvisual class. the frameworkelement class , frameworkcontentelement class both expose setbinding method. drawingvisual not inherit either of these not have method. from msdn : drawingvisual lightweight drawing class used render shapes, images, or text. class considered lightweight because not provide layout, input, focus, or event handling, improves performance. reason, drawings ideal backgrounds , clip art. so intentionally (no event handling), keep fast.

i want ask simple question opengl es 2.x (or think valid of recent opengl releases). which 1 of following faster? : attaching/detaching multiple shaders depending on draw, having uniform variable checking rendering mode; result of going have bunch of if-else conditions(or i.e. switch-case block). know no gpu cores; may assume render same group of primitives subsequently; i.e. not switch 1 mode frequently. if may explain pros/cons of each solution; appreciated. third solution welcome. that depends on volume of data compute, whenever fragment processing bound , many more things. as rule of thumb, changing states should avoided when possible trigger pipeline flush. make thinks worse, changing uniform may trigger pipeline flush. if not using shaders throughput try conditional. edit: if reorder data there small amount of state changes should ok change shader , allow output more fragments. again, depends on bottleneck. tip: measure.
