crop

问题 I am using BJImageCropper for image crop in iOS, but when I am touching on the image's last corner, it's automatically updating the height and width on the opposite side.

问题 The basic idea of what we are trying to do is that we have a large UIImage, and we want to slice it into several pieces. The user of the function can pass in a number of rows and number of columns, and the image will be cropped accordingly (ie. 3 rows and 3 columns slices the image into 9 pieces). The problem is, we're having performance issues when trying to accomplish this with CoreGraphics. The largest grid we require is 5x5, and it takes several seconds for the operation to complete

问题 EDIT: the code given in the "duplicate" question didn't solve the problem for me. The main problem I'm having is that I can't simply use CSS and radius, which would be easy. It's an image being loaded in, in a winforms page/project. I have to try and make a square/rectangle image into a circle. I've tried following 2 methods (results will be posted beneath each): public Image RoundCorners(Image StartImage, int CornerRadius, Color BackgroundColor) { CornerRadius *= 2; Bitmap RoundedImage = new

问题 I have an unordered list displayed as a table. Each list element contains an image and a name/title. The image is cropped to a circle. On hover, I would like the circular crop to become a circular border around the image, such that we see the full image with a circle around the face. My inspiration is from this site: I have successfully cropped the image to a circle, but I am having trouble with the border on hover. You can view my JSFiddle here section.team { margin: auto; background:

问题 I have: <div style="height:15px"> <img src="image" /> </div> The image is bigger than 15px, so it's outside the div when you see it.
