Hi guys, I am trying to read a text file that represent polygon pointers.
example text file format is like following:
o:
Polygon 0/1
704 -1296.625
961.8125 -1242.313
1163.25 -1079.375
1273.594 -880
1310.375 -653.125
Polygon 1/1
661.375 -1207.25
588.3281 -1196.422
514.9375 -1163.938
448.4219 -1104.297
396 -1012
361.9688 -887.9063
Basically, my function reads each line and each line has two numbers. Then I read those two numbers separately in x,y variable. Finally, it displays only those x, y numbers. But I get output like following:
0 0
704 -1296.625
961.8125 -1242.313
1163.25 -1079.375
1273.594 -880
1310.375 -653.125
0 0
661.375 -1207.25
588.3281 -1196.422
514.9375 -1163.938
448.4219 -1104.297
396 -1012
361.9688 -887.9063
0 0
I don't know where all those '0 0' come from. does anyone know what is the cause?
Here is my code:
Qt Code:
float x; float y; if(!myFile.exists()){ qDebug()<<"The file"<<myFile.fileName()<<"does not exist."; return false; } qFatal("Could not open the file"); return false; } while (!st.atEnd()){ QString text; text=st.readLine(); lineNumber++; if (text.contains("Polygon")){ countBoundary++; lineNumberForBoundary.push_back(lineNumber); } if (!text.contains("Polygon")||!text.contains(":")){ st>>x>>y; qDebug() << x << y; } } myFile.close(); return true; }To copy to clipboard, switch view to plain text mode
