问题 I'm writing up a report in R Markdown and I made some tables using the gt package. However, when I attempt to knit to a pdf or html file, I get this error: !

问题 I have googled enough for a whole one day, and searched StackOverflow to find a solution for changing the font in pdf exports of dataTables. However, I didn't run into a solution. When I export the table into pdf script fonts are something undecipherable. Just look at the picture below. It shows two columns from my table. Both dataTables forum and pdfMaker documentations are vague. Can anyone please help me out of the problem. I need to specify a font for pdfMaker extension of datatables. The

问题 I am loading the pdf.js viewer in my webpage in a div using the pdf.js API methods such as run and open. In this page I also have a file upload section to attach related documents. The issue is when I upload a document in the file upload section, using dropzone, the pdf viewer thinks I am uploading a document to it and changes the existing document. Is there a setting to turn this off? I thought there would be something in network.js but I haven't found anything promising yet. 回答1: Here is

问题 Is there a way to resize an image without having it previously written to storage? I am using a pdf library that for the images needs the bytes of it. What I do is get image with an http.get and I get the bytes to put it in the pdf. The problem is that I need to resize the image BEFORE putting it in the pdf. The only thing I have is the url of the image or the uint8list Response response = await http.get(imageUrl); Uint8List imgBytes = response.bodyBytes; Later: Image( PdfImage.file(pdf
