func NormalizePage(page *model.PdfPage) error
NormalizePage performs the following operations on the passed in page:
- Normalize the page rotation. Rotates the contents of the page according to the Rotate entry, thus flattening the rotation. The Rotate entry of the page is set to nil. - Normalize the media box. If the media box of the page is offsetted (Llx != 0 or Lly != 0), the contents of the page are translated to (-Llx, -Lly). After normalization, the media box is updated (Llx and Lly are set to 0 and Urx and Ury are updated accordingly). - Normalize the crop box. The crop box of the page is updated based on the previous operations.
After normalization, the page should look the same if openend using a PDF viewer. NOTE: This function does not normalize annotations, outlines other parts that are not part of the basic geometry and page content streams.
