问题 I found some answers but none of them works for me. I want to make a pdf file from a html, but the problem is that my html has Cyrilic letters and I found that there's something to do with this simple code: String s = "Здраво Kris"; byte bytes[] = s.getBytes("UTF-8"); String value = new String(bytes, "ISO-8859-1"); // I tried with new String(bytes, "UTF-8") but it didn't work Then I pass the value to my pdf generator function but it outputs only the part from the string s that is not in

问题 I am using Nightmare.js to print pdf's. I send a request to the node server and build the page, using Nightmare to ensure the page has loaded, then print a pdf. But for each request I create a new electron window, how do I reuse the same window, or a pool of max X electron windows, to handle my pdf printing? var nightmare = require('nightmare'), http = require('http'); function createPage(o, final) { var page = nightmare() .goto('file:\\\\' + __dirname + '\\index.html'); .wait(function () {

问题 I need your help with this: public void manipulatePdf(String src, String dest) throws IOException, DocumentException { PdfReader reader = new PdfReader(src); PdfDictionary catalog = reader.getCatalog(); PdfDictionary structTreeRoot = catalog.getAsDict(PdfName.STRUCTTREEROOT); manipulate(structTreeRoot); PdfStamper stamper = new PdfStamper( reader, new FileOutputStream(dest)); stamper.close(); } public void manipulate(PdfDictionary element) { if (element == null) return; if (PdfName.FIGURE

问题 I've got a Python script (3.5) that will go through a whole battery of tests. The user gets to select which tests get run out of N possible tests. So, the user could run 1 tests up to N tests. Right now, I'm just outputting the results of the test to a plot with matplotlib and that looks OK, but they're just saved as individual files. Also, the code has some PASS/FAIL criteria for each test. So, the issue is, I would like to use some tool with Python to output the whole story of the test

问题 I'm looking for 2 JS libraries for generating charts and PDFs. I've already tested some, but none of them has satisfied my needs so far. Background: I need to create several independent charts and tables in order to export all of them afterwards into 1 PDF . What I already tried: I have already tested highcharts and amcharts, but they don't seem to work the way I need them. highcharts offers the possibility to create a chart and a table, showing the same data. So same input visualized
