converters

问题 I have created a converter that takes in a SVG file and gives me a text file as output, with some modifications. How can I modify this to apply to a batch of files? I have tried to use multiple="multiple", but when I choose input, it doesn't give me an option to select multiple files. document.getElementById("fileReader").addEventListener('change', function() { var filePath = document.getElementById("fileReader").value; var fileName = filePath.substring(filePath.lastIndexOf("\\") + 1,

问题 I found an example, but this example use a "Int32Rect", class of System.Windows, we can't use this library for android or ios For bitmap, i use the System.Drawing.Common public static System.Drawing.Bitmap BitmapSourceToBitmap2(BitmapSource srs) { int width = srs.PixelWidth; int height = srs.PixelHeight; int stride = width * ((srs.Format.BitsPerPixel + 7) / 8); IntPtr ptr = IntPtr.Zero; try { ptr = Marshal.AllocHGlobal(height * stride); srs.CopyPixels(new Int32Rect(0, 0, width, height), ptr,

问题 I recently found out I can convert a Float32 into an array of bytes that represent it - as such: let number = Math.PI; let bytes = new Uint8Array(new Float32Array([number]).buffer); // [219, 15, 73, 64] Is there a way to convert bytes back into the Float32, in a clean way? 回答1: Is there a way to convert bytes back into the Float32 You don't need to convert it, it's already there! you just need to read it from the float32 view. However in your example you didn't save a reference to the float32

问题 Hello I'm stuck on getting good conversion of a matrix of matlab to pandas dataframe. I converted it but I've got one row in which I've list of list. These list of list are normaly my rows. import pandas as pd import numpy as np from scipy.io.matlab import mio Data_mat = mio.loadmat('senet50-ferplus-logits.mat') my Data_mat.keys() gives me this output: dict_keys(['__header__', '__version__', '__globals__', 'images', 'wavLogits']) I'd like to convert images and wavLogits to data frame.

问题 I'm trying to implement Interface-based Projection but I cannot make it work with my custom type column. Below example of what I'm trying to do: Repository: @Query(value = "SELECT customType from TABLE", nativeQuery = true) List<TestClass> getResults(); Interface projection: public interface TestClass { @Convert(converter = MyCustomTypeConverter.class) MyCustomType getCustomType(); } Converter: @Converter public class MyCustomTypeConverter implements AttributeConverter<MyCustomType, String> {

问题 I'm reading a large JSON file successfully into JObjects. One of the types I'm deserializing into has a property of type System.Drawing.Color. The JSON for this property has an integer value representing the color. When I try to do a ToObject() I get Error converting value 16711680 to type 'System.Drawing.Color'. The solution seems to be a simple JsonConverter that can convert from an integer to a Color but I can't find out how to use the converter with an existing JObject. Am I missing

问题 I'm writing a program to convert an integer to 32-bit binary. The problem is with the output - it comes backwards. #include <stdio.h> int main() { long number, binary, num2; printf("Enter an integer: "); scanf("%ld", &number); for (num2 = (number * 2) / 2; num2 > 0; num2 /= 2) { binary = num2 % 2; printf("%ld", binary); } putchar('\n'); return 0; } So if I put '6' it shows as 011 and it has to be 110 Also, how do I output the rest of '0's? So that the whole output in this case would be:

问题 I want to convert a string value (in hexadecimal) to an IP Address. How can I do it using Java? Hex value: 0A064156 IP: 10.6.65.86 This site gives me the correct result, but I am not sure how to implement this in my code. Can it be done directly in an XSLT? 回答1: try this InetAddress a = InetAddress.getByAddress(DatatypeConverter.parseHexBinary("0A064156")); DatatypeConverter is from standard javax.xml.bind package 回答2: You can split your hex value in groups of 2 and then convert them to
