transformRect function

PdfRect transformRect(
  1. Matrix4 transform,
  2. PdfRect rect
)

Implementation

PdfRect transformRect(Matrix4 transform, PdfRect rect) {
  final point1 = transformPoint(transform, rect.leftBottom);
  final point2 = transformPoint(transform, rect.rightBottom);
  final point3 = transformPoint(transform, rect.leftTop);
  final point4 = transformPoint(transform, rect.rightTop);
  return PdfRect.fromLBRT(
    math.min(point1.x, math.min(point2.x, math.min(point3.x, point4.x))),
    math.min(point1.y, math.min(point2.y, math.min(point3.y, point4.y))),
    math.max(point1.x, math.max(point2.x, math.max(point3.x, point4.x))),
