How to Crop Image in Circle Shape with Grid Inside Circle

How to Crop image in Circle Shape with Grid inside Circle

I find one solution , we can use UIGraphicsGetCurrentContext in CropView and use addEllipse method to draw Circle inside CropView.

this is link For Solution.

Crop image into circular shape at selected region

My guess is that you are probably looking to mask your UIImageView object. Have a look at this tutorial where CoreGraphics were used to resole this problem.

Happy Coding!!

Bootstrap 4 - Cropping image into a circle - landscape photos are not cropped properly

Not sure if this will fit your needs but you could use the background-image property to accomplish this. Here is a working CodePen.

HTML:

<div class="agent-image"></div>

CSS:

.agent-image{

    background-image:url("https://i.gyazo.com/da27f072059db48590e3b9da9d7789c2.jpg");
    background-position:center;
    background-size:cover;
    height: 120px;
    width: 120px;
    border-radius: 50%;

}

Most efficient way to crop image to circle (in R)?

You can improve the performance of your circ function if you do a vectorised subset-assign operation on your array (instead of looping) using the the fact that (x-xc)^2 +(y-yc)^2 > r^2 for points outside a circle.

To do this, replace the 2nd part of your function with

  # Second part of the function traces circle by...
  x = rep(1:xmax, ymax)
  y = rep(1:ymax, each=xmax)
  r2 = r^2
  ma[,,4][which(( (x-xc)^2 + (y-yc)^2 ) > r2)] <- 0
  return(ma)

How to crop a square Image and change it into a circle C#

UPDATE thanks to @TaW I've updated g.SetClip(path) instead of new region

1. Make a new Bitmap that matches the original in size and pixel
   format.
2. Create a graphics from that new Bitmap.

3. Set the graphics

4. clip to a new circle

5. Draw the original image onto the new graphics.

Here is an example:

public Bitmap ClipToCircle(Bitmap original, PointF center, float radius)
{
    Bitmap copy = new Bitmap(original);
    using (Graphics g = Graphics.FromImage(copy)) {
        RectangleF r = new RectangleF(center.X - radius, center.Y - radius,
                                      radius * 2, radius * 2);
        GraphicsPath path = new GraphicsPath();
        path.AddEllipse(r);
        g.SetClip(path)
        g.DrawImage(original, 0, 0);
        return copy;
    }
}

I hope it solves your issue.

iPhone programmatically crop a square image to appear as circle

Yes you can use CoreGraphics to draw the mask dynamically.
Then you can create the masked image.

Example for masking:

- (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage
{
  CGImageRef maskRef = maskImage.CGImage;
  CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef),
                                      CGImageGetHeight(maskRef),
                                      CGImageGetBitsPerComponent(maskRef),
                                      CGImageGetBitsPerPixel(maskRef),
                                      CGImageGetBytesPerRow(maskRef),
                                      CGImageGetDataProvider(maskRef), NULL, false);

  CGImageRef maskedImageRef = CGImageCreateWithMask([image CGImage], mask);
  UIImage *maskedImage = [UIImage imageWithCGImage:maskedImageRef];
  CGImageRelease(maskedImageRef);
  CGImageRelease(mask);
  return maskedImage;
}
