PdfPageSize class

The intrinsic size of a PDF page, measured in PDF user units (points).

One PDF user unit equals 1/72 inch. This is a storage-level measurement independent of any rendering resolution. Use sizeForDpi to convert to pixel dimensions at a target DPI for rendering.

Example

final size = await doc.getPageSize(0);
// Convert to pixels at 150 DPI:
final pixelSize = size.sizeForDpi(150);
final image = await doc.renderPageToBytes(
  0,
  pixelSize.width.round(),
  pixelSize.height.round(),
);

Constructors
