NSString* letter = Ĭhar* c = (char*) ĬGSize charSize = [letter with size: %f x %f", letter, charSize.width, charSize.height) įloat letterAngle = (charSize.width / perimeter * -2 * M_PI) ĬGContextRotateCTM(context, (angle - 0.5 * M_PI)) ĬGContextShowTextAtPoint(context, 0, 0, c, strlen(c)) I could use some help with that.Įdit: Fixed! Check out the following code! - (void) drawStringAtContext:(CGContextRef) context string:(NSString*) text atAngle:(float) angle withRadius:(float) radiusįloat textAngle = textSize.width / perimeter * 2 * M_PI Now I need somehow figure out at which rotation the letters (and their coordinates) should be.
The rotation of the words seem correct, the placement also. These are the variables I use in there: NSArray* sections = iets", nil] NSString* menuItemText = ĬGSize textSize = Ĭhar* menuItemTextChar = (char*) įloat x = centerPoint.x + radius * cos(degreesToRadians(totalRotation)) įloat y = centerPoint.y + radius * sin(degreesToRadians(totalRotation)) ĬGContextRotateCTM(context, degreesToRadians(totalRotation - 90)) ĬGContextShowTextAtPoint(context, 0 - (textSize.width / 2), 0 - (textSize.height / 2), menuItemTextChar, strlen(menuItemTextChar)) ĬGImageRef contextImage = CGBitmapContextCreateImage(context) I accomplish by using the following code: - (UIImage*) createMenuRingWithFrame:(CGRect)frameĬGRect imageSize = CGRectMake(0,0,300,300) įloat perSectionDegrees = 360 / Ĭhar* fontName = (char*) ĬGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB() ĬGContextRef context = CGBitmapContextCreate(NULL,, , 8, 4 *, colorSpace, kCGImageAlphaPremultipliedFirst) ĬGContextSetTextMatrix(context, CGAffineTransformIdentity) ĬGContextSelectFont(context, fontName, 18, kCGEncodingMacRoman) ĬGContextSetRGBFillColor(context, 0, 0, 0, 1) ĬGPoint centerPoint = CGPointMake( / 2, / 2) ĬGContextStrokeEllipseInRect(context, CGRectMake(centerPoint.x - ( / 2), centerPoint.y - ( / 2),, )) įor (int index = 0 index < index++) I hope someone can get me some starting points on how I can draw the text in the white circle, at certain points. Only the texts I added by are loaded from an image in an UIImageView. I included a screenshot on what the menu, at the moment, look like.
#How to curve text in word 2016 for mac how to#
I just can't wrap my head around on how to get the right angles and positions for my characters. I read most stuff about curving a text that you have to split up your text in characters and draw each character on it's own with the right angle in mind (by rotating the context you are drawing on). I want to curve text between those lines, for a circular menu I am building. For an application I am building I have drawn 2 circles.
