问题 Hello I am having task to create custom shape figure. On the bottom the shape of figure is rectangle and on half top of rectangle is cut by circle shape. Can anyone give me direction where to go from now? 回答1: import React, { Component } from 'react'; import { View } from 'react-native'; import { Icon} from 'react-native-elements' class BottomNavigator extends Component { render() { return ( <View style={{ flex: 1, flexDirection: 'column', backgroundColor: '#f8f4f4' }}> <View style={{

问题 I have to implement a banner according to the following designs: The complexity here is in the shadow of the round logo, the shadow of the logo circle is the continuation of the shadow of the rectangular card of the banner. The border of the shadow is outlined in the following image: Of course the shadow shouldn't be casted on the surface below the top side of the card. Also the logo center has some offset from the border of the card. How can I achieve this effect? Standard android shapes

问题 I am having a hard time understanding the output shape of keras.layers.Conv2DTranspose Here is the prototype: keras.layers.Conv2DTranspose( filters, kernel_size, strides=(1, 1), padding='valid', output_padding=None, data_format=None, dilation_rate=(1, 1), activation=None, use_bias=True, kernel_initializer='glorot_uniform', bias_initializer='zeros', kernel_regularizer=None, bias_regularizer=None, activity_regularizer=None, kernel_constraint=None, bias_constraint=None ) In the documentation

问题 I have a simple image containing some shapes: some rectangles and some ellipses, in total number of 4 or 5. The shapes can be rotated, scaled and overlapped. There is a sample input: My task is to detect all of these figures and prepare some information about them: size, position, rotation, etc. In my opinion, the core problem is the fact that the shapes can be overlapped by each other. I tried to search some information about this kind of problem and find that OpenCV library can be very

问题 I'm writing a basic 2D shape library in Python (primarily for manipulating SVG drawings), and I'm at a loss for how to efficiently calculate the intersection points of two ellipses. Each ellipse is defined by the following variables (all floats): c: center point (x, y) hradius: "horizontal" radius vradius: "vertical" radius phi: rotation from coordinate system's x-axis to ellipse's horizontal axis Ignoring when the ellipses are identical, there could be 0 through 4 intersection points (no

问题 I am trying to select a shape by name using VBA. In my sheet, I have 10 shapes named 1 to 10 and want a specific one. For some reason, the shape that excel selects with my code does not seem to be the shape with the name I told it to select. As far as I can tell, the shape that it chooses is random. Here is my code (The x value is supposed to retrieve a number value that I input from 1 to 10): Sub FindTheShape() Sheets("Fleet 1").Select Dim x As Long x = ActiveSheet.Range("$A$1000").End(xlUp)

问题 I am working on a shape detection algorithm with opencv in python . I am using Contours from the library and I have had some shapes being detected successfully: Circle, Rectangle and Triangle. The only problem is that I only need to detect circles rectangles and octagons. Also, the circle was working, but inconsistently. So, this is my code: import cv2 import numpy as np def nothing(x): # any operation pass cap = cv2.VideoCapture(1) cv2.namedWindow("Trackbars") cv2.createTrackbar("L-H",
