| Summary | 0023623: Get wrong values of colors using QAGetPixelColor on Windows VC++ 2012 32bit | ||||
| Description | Trying to check color of two vertexes returns invalid result (maybe shape is slightly shifted). But we get to the vertexes using the same coordinates launching this case on Mandriva2010 32-bit and Windows 7 VC++ 2008 64-bit. | ||||
| Steps To Reproduce | restore [locate_data_file OCC322.brep] a sewing result a vinit vdisplay result vfit ### coordinates of first vertex set x1 204 set y1 297 ### coordinates of second vertex set x2 251 set y2 232 ### vertexes should be yellow color (RGB 1 1 0) QAGetPixelColor $x1 $y1 1 1 0 QAGetPixelColor $x2 $y2 1 1 0 | ||||

Dear bugmaster, As a matter of fact, the 3D scene image might be shifted slightly, depending on the particular platform/graphic card/graphic driver version. We observed this several times in the past. Thus QAGetPixelColor is not a reliable way to check the visual result and should be used with care (e.g. on continuous uniformly shaded regions - but not on the sharp thin edges). We cannot fix this, unfortunately. Can you please close this issue? |
