问题 For one of my current javafx projects I'm working with Venn Diagrams. I'd like to take advantage of Shape.intersect to ease the amount of math calculations I'd have to personally work through (and avoid working with Path objects). Shape.intersect produces a perfect shape, but it is translated / moved a bit and I can't figure out how much to put it back. Ideally, I'd like to have the intersection area occur exactly where the two original shapes intersect - i.e. the new intersection would fit

问题 I'm trying to do something which I'd think would be fairly easy but can't find a straight forward answer to. Basically I want to change a JPanel's default shape to a circular shape (or any other shape other than a rectangle). 回答1: You will need to provide your own custom painting routines. The other problem you will have is getting the layout managers to work with it, but you can supply your own insets to provided an area within the panel that can safely used You'll also want to make the

问题 I have an IBOutlet button dragged from Interface Builder (it's easier to play with it in auto layout ) I rotated it by 45° in code as learned here var transform = CGAffineTransformMakeTranslation(0.5, 0.5) var angle = CGFloat(M_PI / 3.9) // degress rotation 3.9 transform = CGAffineTransformRotate(transform, angle) button.transform = transform button.layer.rasterizationScale = UIScreen.mainScreen().scale button.layer.shouldRasterize = true button.setNeedsDisplay() now, I have diamond, triangle

问题 I made a sample code in VS 2013 preview, I made a line inside a canvas with stroke color of white, but the line is shown so strangely like more thick and not white (almost gray). same sample I tried it in VS 2010 and it output well. Can anyone tell me what's going on...? <Canvas Width="200" Height="200" Background="Black"> <Line X1="30" Y1="60" X2="90" Y2="60" Stroke="White" StrokeThickness="1"/> <Line X1="60" Y1="30" X2="60" Y2="90" Stroke="White" StrokeThickness="1"/> </Canvas> //EDIT when

问题 My question is simple as that: 1)I have main class which extends a JFrame. 2)Inside that class there is a JPanel with a BufferedImage on top of it. 3)Finally there is also a JButton which I call "Fire"..that's all for the design.. Now here's the deal: When pressing the button there's a little method which returns me an array of 5 Ellipse2D objects. (The array is called "points" and is in essence an array of simple circles..). All I want to do when pressing "Fire" is get these objects show up

问题 I've got an interesting task. I need to detect a click on the border of a shape in Kinetic JS. In this case the shape is a polygon but bonus points if it works with any shape. My first idea would be to draw lines around the border of the shape, perhaps with an opacity of 1, and then using their click events on pick up the click. It's a bit of PT though so I thought I'd run it past here and see if there were any other ideas. Thanks for the help! 回答1: You can do it by combining two shapes

问题 I need to create an empty shape file and populate it with data from my java colletion. Can someone show me an example of how to achieve this? Thanks in advance. 回答1: For full details please see the CSV to Shapefile tutorial. Basically you need to define the Shapefiles columns in a SimpleFeatureType object, the easiest way to do this is to use a SimpleFeatureTypeBuilder . Here is generated from directly using a utility method to save time. final SimpleFeatureType TYPE = DataUtilities

问题 The question is this: how can I save the shape a MSER image give me as output ? I already received an answer here but using bounding boxes. What I want is to save the shape as it seems to result a bit more accurate than a box. For the code I am using, take a look at the answer linked above. The output should be a single shaped-ROI extracted from this image (look at text window): 来源： https://stackoverflow.com/questions/47632535/save-shape-of-mser-python-opencv
