Using CGContextFillPath and CGContextStrokePath Together ? iOS
cgcontext, graphics, ios, objective-c, quartz-2d
Solution
The path is consumed when you fill it. If you want to both fill and stroke then you should use
CGContextDrawPath(conPattern, kCGPathFillStroke); // both fill and stroke
Problem
I am drawing a Quartz 2D shape using CGContextFillPath as follows : ``` CGContextRef conPattern = CGBitmapContextCreate(NULL, shp.size.width*2, shp.size.height*2, 8, 0, rgbColorSpace, (CGBitmapInfo)kCGImageAlphaPremultipliedFirst); CGContextSetLineWidth(conPattern, 10); CGContextSetStrokeColorWithColor(conPattern, [UIColor blackColor].CGColor); Line * start = [verticesPassed objectAtIndex:0]; StandPoint * startPoint = start.origin; CGContextMoveToPoint(conPattern, ([startPoint.x floatValue]-shp.origin.x)*2 , ([startPoint.y floatValue]-shp.origin.y)*2); for (Line * vertice in verticesPassed) { StandPoint * standPoint = vertice.origin; CGContextAddLineToPoint(conPattern, ([standPoint.x floatValue]-shp.origin.x)*2, ([standPoint.y floatValue]-shp.origin.y)*2); } CGContextSetFillColorWithColor(conPattern, [UIColor yellowColor].CGColor); CGContextFillPath(conPattern); [self drawText:conPattern startX:0 startY:20 withText:standName]; [self drawText:conPattern startX:0 startY:50 withText:standNumber]; //Make the main image and color it with pattern. CGImageRef cgImage = CGBitmapContextCreateImage(conPattern); UIImage *imgPattern = [[UIImage alloc]initWithCGImage:cgImage]; ``` This works well and draws my filled shape. What I want to do as well however is show the lines that have been drawn. I tried added in CGContextStrokePath but with no luck : ``` Line * start = [verticesPassed objectAtIndex:0]; StandPoint * startPoint = start.origin; CGContextMoveToPoint(conPattern, ([startPoint.x floatValue]-shp.origin.x)*2 , ([startPoint.y floatValue]-shp.origin.y)*2); for (Line * vertice in verticesPassed) { StandPoint * standPoint = vertice.origin; CGContextAddLineToPoint(conPattern, ([standPoint.x floatValue]-shp.origin.x)*2, ([standPoint.y floatValue]-shp.origin.y)*2); } CGContextSetFillColorWithColor(conPattern, [UIColor yellowColor].CGColor); CGContextFillPath(conPattern); CGContextStrokePath(conPattern); ``` Can anyone suggest how I can achieve this ?
