Color of scan frame

[HallmediaDigital]

Currently on IOS there is a green and red frame that indicates where to focus the scanner. Can these colors be customized. ?

It would be really great to be able to customise the color/size of the overlay frame as well as the text prompt ("Place a barcode inside the viewfinder rectangle to scan it")._my app is meant only to scan qrcodes

I found out the solution.. if you go into /{ProjectFolder}/platforms/ios/{AppName}/Plugins/phonegap-plugin-barcodescanner/CDVBarcodeScanner.mm

you can customize the UI of green box and red line. almost at the end of the code, you see this:

`#define RETICLE_SIZE 500.0f

define RETICLE_WIDTH 5.0f

define RETICLE_OFFSET 60.0f

define RETICLE_ALPHA 0.4f

//------------------------------------------------------------------------- // builds the green box and red line //-------------------------------------------------------------------------

• (UIImage)buildReticleImage { UIImage result; UIGraphicsBeginImageContext(CGSizeMake(RETICLE_SIZE, RETICLE_SIZE)); CGContextRef context = UIGraphicsGetCurrentContext();

  if (self.processor.is1D) { UIColor* color = [UIColor colorWithRed:1.0 green:0.0 blue:0.0 alpha:RETICLE_ALPHA]; CGContextSetStrokeColorWithColor(context, color.CGColor); CGContextSetLineWidth(context, 0.5_RETICLE_WIDTH); CGContextBeginPath(context); CGFloat lineOffset = RETICLE_OFFSET+(0.5_RETICLE_WIDTH); CGContextMoveToPoint(context, lineOffset, RETICLE_SIZE/2); CGContextAddLineToPoint(context, RETICLE_SIZE-lineOffset, 0.5*RETICLE_SIZE); CGContextStrokePath(context); }

  if (self.processor.is2D) { UIColor* color = [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:RETICLE_ALPHA]; CGContextSetStrokeColorWithColor(context, color.CGColor); CGContextSetLineWidth(context, RETICLE_WIDTH); CGContextStrokeRect(context, CGRectMake( RETICLE_OFFSET, RETICLE_OFFSET, RETICLE_SIZE-2_RETICLE_OFFSET, RETICLE_SIZE-2_RETICLE_OFFSET ) ); }

  result = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return result; } `

I already edited a little bit, and I got a beautiful white box and slimmer red line.

is it possible to increase the width of the box ?

I think so.. why don't you change RETICLE_SIZE? first parameter for CGSizeMake() and third parameter for CGRectMake() are both width, so you should play with those!
