I have tried different ways with using of: SDL_RenderClear(_Renderer); or even with drawing and on created texture with painting transparent

问题 Hey I am adding the following image in the Jpanel: msu-footprints.org/2011/Aditya/map.jpg And then adding polygon : int[] x = new int[]{65, 122, 77, 20}; int[] y = new int[]{226, 258, 341, 310}; g.setColor(Color.RED); g.drawPolygon(x, y, x.length); The polygon should coincide with building GER but is a little bit offset. My proff says the co-ordinates are okay. Is there anything wrong with how I put the image position? – 回答1: If painting directly to the top level container (JFrame), then the

问题 how i use #include <graphic.h> in windows 7 and i use graphic function in visual studio c++ or borland c++ ??? tnx,but : Which library in Console Application mode work? 回答1: graphics.h is not a standard c++.

Query to check if there is a cycle in a graph with edges visited only once

How to write an query runs on my graph, that outputs 'false' if there is NO path traversing through each edge only once and return to the starting point. I was using the following sample graph : g = TinkerGraph.open().traversal() g.addV().property(id, 'blue').as('b'). addV().property(id, 'orange').as('o'). addV().property(id, 'red').as('r'). addV().property(id, 'white').as('w'). addE('bridge').from('w').to('b'). addE('bridge').from('w').to('o'). addE('bridge').from('w').to('r'). addE('bridge').from('w').to('r'). addE('bridge').from('o').to('b'). addE('bridge').from('o').to('b'). addE('bridge')
