问题 I just want an advice or suggestions of how i can do it. i've been thinking about it for hours now and can't find a solution. My aim is to convert this ER Diagram to tables. So i have a Rectangle(Entity) that is linked to an ellipse(Attribute). I've already worked out on the collisions of the shapes where the line will retrieve the object that is linked to it. See the picture below: the result will be as follows when the above diagram is drawn: LINE(1) COLLIDES WITH RECTANGLE OF INDEX(0) LINE

I've made a button background from shapes and is looking quite good for my purpose. The only thing needed is to drop a bit of shadow for it. Here is the code: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true"> <shape> <solid android:color="#343434" /> <stroke android:width="1dp" android:color="#171717" /> <corners android:radius="3dp" /> <padding android:bottom="10dp" android:left="10dp" android:right="10dp" android:top="10dp" /> </shape> </item> <item> <shape> <gradient android:angle="270" android

问题 I recently began to learn libgdx and I am stuck at a problem with the CainShape of Box2D. My first goal is to simply create a box with a ChainShape. In order to achieve that, I added four Vector2 to an array and use them to create a loop. The result is depending on the arrangement in the array either an hourglass shaped thing (top left is connected with bottom right and top right is connected with bottom left) or the error Expression: b2DistanceSquared(v1, v2) > 0.005f * 0.005f This is the

Creating a rectangle shape with only two rounded edges

I can create a shape that is a rectangle with all edges rounded. However, what I'm wanting is a rectangle shape with only 2 of the edges rounded. Is this possible? I'm essentially hacking together a ListView that looks like a bubble with rounded edges. I'm looking to add a header that has the two top edges rounded and a footer with the two bottom edges rounded. <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" android:padding="10dp"> <solid android:color="#FFFFFF"/> <corners android:bottomRightRadius="0dp" android:bottomLeftRadius="0dp" android

More than six shapes in ggplot

I would like to plot lines with different shapes with more than six sets of data, using discrete colors. The problems are 1) a different legend is generated for line color and shape, but should be only one legend with the line color and shape, 2) when correcting the title for the line color legend, the color disappear. t=seq(0,360,20) for (ip in seq(0,10)) { if (ip==0) { df<-data.frame(t=t,y=sin(t*pi/180)+ip/2,sn=ip+100) } else { tdf<-data.frame(t=t,y=sin(t*pi/180)+ip/2,sn=ip+100) df<-rbind(df,tdf) } } head(df) # No plot # Error: A continuous variable can not be mapped to shape gp <- ggplot(df

Shape detection in image using Matlab

依然范特西╮ 提交于 2019-12-02 14:41:19
I have an image with many shapes and I need to write some Matlab code which remove all the shapes except the rectangle.. Does it availabe to do it using only with strel,imclose and bwareaopen? if you think yes i will be very happy to hear your opinion. Image: If I understood right from your comment, rectangle may have any size. I think this can be asked only if the other shapes have fixed size since you are asked to use strel, imclose and bwareaopen. To briefly explain, strel function creates a structuring element with given size for rectangle, disk or any other shape on the picture you added.

Shapes combination in Java?

我们两清 提交于 2019-12-02 12:43:38
问题 Does java Shape interface contract and library routines allow combining multiple shapes into one object extending Shape interface? For example, may I define class Flower which will consist of several ovals for petals and core? Or the Shape supposes only one continuous outline? If so then is there any class in Java for holding multiple shapes, may be some class for vectorized graphics? 回答1: To manipulate shapes in Java like you're describing, you want to use the Area class, which has these
