getPageSize method
- int pageIndex
Returns the intrinsic size of a page in PDF user units (points).
One PDF user unit equals 1/72 inch. This is a storage-level measurement independent of rendering resolution. Use PdfPageSize.sizeForDpi to convert to pixel dimensions for a renderPageToBytes call.
Throws RangeError if pageIndex is out of range.
Throws StateError if close has already been called.
Example
final size = await doc.getPageSize(0);
final px = size.sizeForDpi(150);
final result = await doc.renderPageToBytes(0, px.width.round(), px.height.round());
Implementation
Future<PdfPageSize> getPageSize(int pageIndex) =>
_impl.getPageSize(pageIndex);
