问题 I've got a method for masking a B&W image by cutting out (i.e. making transparent) any pixels that are above or below a certain brightness. The result would be the same B&W image, but with everything above 70% or below 25% brightness (or whatever you choose) changed to transparent. It was working perfectly on iOS 11, but it broke on iOS 12. It now returns the original, solid image with no modifications every time. -(UIImage*)imageWithLumaMaskFromDark:(CGFloat)lumaFloor toLight:(CGFloat

问题 I am writing script in Abaqus, where I crush circle and square with cut circle (like cheese). I need to put Contact between parts so I need Surface. macro manager generates: s1 = a.instances['kolo-1'].edges side1Edges1 = s1.getSequenceFromMask(mask=('[#1 ]', ), ) a.Surface(side1Edges=side1Edges1 , name='kolkoSurf') The problem is: getSequenceFromMask(mask=('[#1 ]', ), ) How to get this #1? Can I replace it? I searched little and there were some ideas to use: 'find', 'face', 'COORDS' but I

问题 Trying to animatie an ellipse masked on a UIView to be scale transformed remaining in the center position. I have found CALayer - CABasicAnimation not scaling around center/anchorPoint, and followed by adding a bounds property to the maskLayer CAShapeLayer however, this ends with the mask being positioned in the left corner with only 1/4 of it showing. I would like the mask to remain within the center of the screen. @synthesize maskedView; - (void)viewDidLoad { [super viewDidLoad];

问题 Suppose I need to set an opacity mask on a WPF control that highlights a portion of it in precise position (suppose a 50x50 square at (50;50) position). To do that I create a DrawingGroup containing 2 GeometryDrawing objects: 1 semi-transparent rectangle for the whole actual size of the control and 1 opaque rectangle for highlighted area. Then I create a DrawingBrush from this DrawingGroup, set it's Stretch property to None and set this brush as OpacityMask of the control that needs to be

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed last year . Improve this question when I try to use this piece of code, it only works for 1 object, not for every. I'm trying to modify code from this video (https://www.youtube.com/watch?v=Idu8XfwKUao). Is there is a simpler way to get a result ?.If there is,please let me know #part of code that doesn't matter
