[dolonk]

render({
int x = 0,
int y = 0,
int? width,
int? height,
scale: 2.0,
});
is it possible?

PdfPage.render function has parameters named fullWidth and fullHeight and I guess they are what you are talking about.

final image = await page.render(
  fullWidth: page.width * 2.0,
  fullHeight: page.height * 2.0,
);

final pdfDocument = await PdfDocument.openAsset('assets/testing document.pdf');
totalPage = pdfDocument.pages.length;
pageWidth = pdfDocument.pages[0].width;
pageHeight = pdfDocument.pages[0].height;

pdfImages = await Future.wait(
  [
    for (int i = 0; i < totalPage!; i++)
      pdfDocument.pages[i].render(
            width: pageWidth!.toInt(),
            height: pageHeight!.toInt(),

        fullWidth:pageWidth! * 2.0,
        fullHeight: pageHeight! * 2.0,

          )
          .then((pdfImage) => pdfImage!.pixels)
  ],
);

could you tell me what the difference is between fullWidth, fullHeight, and width, height
