fill

问题 I want to create a CSS class to fill a path with image that can be applied on any SVG path and fill that path with image. The image must be stretch to fit that path. To achieve this; I create a pattern with image tag and set the width and height as 100% . but the image takes 100% of the whole screen instead of objectBoundingBox of the container (in this case svg tag). Below is the sample code: .myClass { fill: url(#image); stroke: red; stroke-width: 5; } <svg id='pattern' xmlns="http://www.w3

问题 I have three points, for example: Start 194 171 Right 216 131 Left 216 203 I want to get all the points within that triangle. How would I do that efficiently? 回答1: see z3nth10n's answer for better input validation Introduction: The general idea was to get the triangle's edges (y-Wise) for every x in it's range, and then you have all the y's that exist within the triangle for every single x, which with simple conversion turns into all points within the triangle. You can look at it as if you

问题 I am trying to plot the shaded uncertainty (upper and lower bounds) along a line. I tried using the fill function but it is including an area larger than I want. I have an upper error (black), lower error (green), and actual data line (red), like so: How do I get the area between the green and black lines? I tried the following: fill([date fliplr(date)], [data_Upper fliplr(data_Lower)], 'r'); But the fill function covers both line areas all the way to the bottom of the plot: How do I fix this

问题 I'm trying to render a circle with a radial gradient but I can't seem to figure it out. var bkgdGrad:Shape = new Shape(); bkgdGrad.graphics.beginGradientFill(GradientType.RADIAL, [0x0000FF, 0x00FF00], [1, 1], [0, 255],null,"pad"); bkgdGrad.graphics.drawCircle(0,0,r+200); bkgdGrad.graphics.endFill(); this.addChild(bkgdGrad); The above code renders a solid green circle for me.

问题 This is a red box: 162 86 m 162 286 l 362 286 l 362 86 l h 1 0 0 rg f How can I add partial transparency to it? I've read the transparency section of the PDF spec, but I can only seem to find models and formulas, not how to actually add alpha to a fill. 回答1: As the OP indicated, there is a whole section in the PDF specification on the topic of Transparency . This is due to a multitude of ways to apply transparency. The most appropriate way for the OP's context is explained in the following

问题 I'm using WebBrowser control to fill a web page . is it possible to using WB inside a thread ? Thank you 回答1: TWebBrowser is a VCL control. Therefore, it must be created and operated in the main VCL thread. The control already acts asynchronously, though. When you tell it to navigate to a page, it will do that in the background and notify you (via OnNavigateComplete and other events) when it's finished. 来源： https://stackoverflow.com/questions/3735410/is-it-possible-to-using-webbrowser-in-a

问题 I have a progress bar that drops in when the user scrolls down more than 100 pixels. The background of the progress bar fills with red. The progress bar container also contains an svg of a tree which is white. How can I change the fill color of the svg as the progress bar passes behind it. So, if the progress bar is halfway through the back of the tree, the left half would be white and the right half would still be red. Is that even possible? I am using jQuery currently. I mocked up a quick
