How to clip Image (UI-element) to sample geometry?

由 岁酱吖の 提交于 2019-12-08 07:06:51
问题 I want clip Image to ellipse, for example. UI-element have Clip, but Clip in the Windows Runtime API must be a RectangleGeometry. I can achieve the same result using an Ellipse and ImageBrush element as Fill brush: How to clip image to ellipse in XAML But then i can not size or move my image, because it's brush, not UI-element. So, how clip image not rectanglegeometry? For example, i want this:Move image into ellipse Maybe, i can use alphamask to UI-element? Or OpacityMask? Maybe this is

D3 Brush coordinates under CSS transform scale

由 无人久伴 提交于 2019-12-08 07:00:50
问题 D3 brush does not function properly under css transform scale. When svg is under div element, and div element is transformed using CSS scale, the brush operation shows wrong coordinates. To demonstrate this case, here is the jsFiddle. It is simple modification from Bostock's Brushable Network example. What I did was simply putting SVG in the div element and made div element zoom 50% using CSS transform scale(0.5). And the brushing coordinates are not updating because of zooming. #test {

Shiny click/brush not working with non-cartesian coordinates?

由 陌路散爱 提交于 2019-12-07 20:54:15
问题 I am working on a Shiny app that should let a user select geographical data points on a world map generated by ggplot2 (as in this example). This works if I use the regular coord_cartesian coordinate system (which distorts the maps) but fails if I use the more appropriate coord_map coordinate system. It seems like the click/brush events do not receive the correct coordinates after the projection. Is there any way I can work around or fix this without reverting back to cartesian coordinates?

d3.js: limit size of brush

由 家住魔仙堡 提交于 2019-12-07 03:35:57
问题 Is there a way to limit the size of a brush, even though the extent is larger? I put together a brush with only an x-scale that can be moved and resized. I would like to be able to limit the extent to which it can be resized by the user (basically only up to a certain point). In the following example, the brush function stops updating when the brush gets bigger than half the maximum extent. The brush itself, though, can still be extended. Is there a way to prevent this from happening? Or is

Zooming and brushing in d3 force directed graph

问题 I'm having a problem in getting D3 to perform proper brushing when zooming is performed. I have a jsFiddle created here http://jsfiddle.net/Gwp25/2/ showing the network with some dummy data I found elsewhere. The operation to follow is this. Zoom in (using mousewheel), then turn on brushing. After doing this, brush the nodes. The nodes that are selected are off - some out of the brush area. Here is the relevant part of the code dealing with the selecting of nodes within the brush extent. .on(

WPF 'magic' negating brush?

由 佐手、 提交于 2019-12-05 01:42:02
I have a gradient that changes its colors, I want the text inside it should always be visible. I rather doing it dynamically if there is any out-the-box resource; I want a 'magic brush' that negates the color. Any experiments? Well, color inversion could possibly be done as a bitmap effect, but there's a simpler way. Make a Grid that will be the container for 3 child panels so that these child panels will overlap each other completely: Put the text where you want it in a panel that has a Transparent background (they do by default). Name this panel 'mask'. Make another panel called
