1 year ago Hi! For anyone still looking for a workaround for this issue, this may help. I use the python and WeasyPrint exe's directly and so I may pass CreateNoWindow = true to the process.
private static readonly FilesManager WeasyPrintManager = new();
private static string? WeasyPrintPython = null;
private static string? WeasyPrintDir => WeasyPrintManager.FolderPath;
public static async Task Init() {
if (!WeasyPrintManager.IsFilesExsited()) {
await WeasyPrintManager.InitFilesAsync();
}
WeasyPrintPython = Path.Combine(WeasyPrintManager.FolderPath, "python.exe");
}
public static async Task Convert(string htmlPath, string pdfPath) {
var p = new Process() { StartInfo = new() {
FileName = WeasyPrintPython,
CreateNoWindow = true,
WorkingDirectory = WeasyPrintDir,
RedirectStandardError = true,
} };
p.StartInfo.EnvironmentVariables["PATH"] = "Scripts;gtk3;" + Environment.GetEnvironmentVariable("PATH");
p.StartInfo.ArgumentList.Add("scripts/weasyprint.exe");
p.StartInfo.ArgumentList.Add("-e");
p.StartInfo.ArgumentList.Add("utf8");
p.StartInfo.ArgumentList.Add(htmlPath);
p.StartInfo.ArgumentList.Add(pdfPath);
p.Start();
await p.WaitForExitAsync();
var stderr = await p.StandardError.ReadToEndAsync();
if (p.ExitCode != 0) throw new Exception(stderr);
}
first of all, thanks a lot for this .net wrapper, very handy to use. I tried to test it from a winform application, it shows up a black command line window quickly and closes automatically. is there a solution to this issue?
private async void button1_Click(object sender, EventArgs e) { using (WeasyPrintClient client = new WeasyPrintClient(trace)) { var html = "<!DOCTYPE html><html><body><h1>Hello World</h1></body></html>"; var fileContent = await client.GeneratePdfAsync(html); File.WriteAllBytes(@"D:\TT\temp\test.pdf", fileContent); } }
