Add more safe builder methods for setting global and object settings
and figure out or report upstream other flags that don't seem to work (like outlineDepth)
How would you pass other arguments to builder for wkhtmltopdf? Specifically I would like to pass --user-style-sheet
@anowell could you please confirm the desired way to add command line arguments that don't have a safe rust function.
Is using fn global_setting() the way to go about this?
let html = r##"<!DOCTYPE html><html><head><meta charset="utf-8"></head><body>Hello World</body></html>"##
unsafe {
let pdf_app = PdfApplication::new().expect("Failed to init PDF application");
let mut pdfout = pdf_app
.builder()
.global_setting("encoding","UTF-8")
.build_from_html(&html)
.expect("failed to build pdf");
}
I think global_settings would only work for the fields defined on the PdfGlobal object in the upstream project (also documented as Pdf Global Settings which includes the load.* settings).
The web settings (e.g. encoding and stylesheet) appear to be on the PdfObject. So while I haven't tested it, I'd expect to use: .object_setting("web.defaultEncoding", "UTF-8") and .object_setting("web.userStyleSheet") to accomplish the questions in this issue.
And if those are correct, it should be pretty trivial to add the safe builder methods:
pub fn default_encoding(&mut self, encoding: &str) -> &mut PdfBuilder {
self.os.insert("web.defaultEncoding", encoding.to_string().into());
self
}
pub fn user_style_sheet<P: AsRef<Path>>(&mut self, style_sheet: P) -> &mut PdfBuilder {
self.os.insert("web.userStyleSheet", style_sheet.as_ref().to_string().into());
self
}
