Error when compiling on Windows

AbdesamedBendjeddou commented 2 years ago

running these two programs seems to give a compile error on windows

use pdfium_render::prelude::*;

fn main()   {
    let pdfium = Pdfium::new(
        Pdfium::bind_to_library(Pdfium::pdfium_platform_library_name_at_path("./"))
            .or_else(|_| Pdfium::bind_to_system_library()).unwrap(),
    );

    // Create a new document containing a single page with the desired sample text.

    let document = pdfium.create_new_pdf().unwrap();

    let mut pages = document.pages();

    let mut page = pages.create_page_at_start(PdfPagePaperSize::a4()).unwrap();

    // Desired sample text:

        line_top -= line_spacing;

    document.save_to_file("before.pdf").unwrap();

// this just a part of the program I included only the part where the error seems to occur

                            word_left += bold_part.width().unwrap();
//the error:
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: PdfiumLibraryInternalError(Unknown)', src\place.rs:67:70

since create_text_object() use translate() method in its definition I'm assuming that both errors are in fact the same. both programs compile fine on WSL It is worth mentioning that opening a file, removing text objects from it and saving the edited version worked fine. probably because we didn't need to use translate() method.
