| Rotation | TRotation. Clockwise rotation to apply when rendering: ro0, ro90, ro180, or ro270. |
| Options | TRenderOptions. Set of rendering flags controlling annotation display, LCD text, grayscale, etc. |

| Rotation | TRotation. Clockwise rotation to apply when rendering. |
| Options | TRenderOptions. Set of rendering flags. |
procedure RenderPage(Bitmap: TBitmap; Left, Top, Width, Height: Integer; Rotation: TRotation = ro0; Options: TRenderOptions = []);

Renders the current page to the specified destination at the given position and size. Three overloads are available:
TBitmap and renders into it. The caller must free the returned bitmap.TBitmap (no allocation).The background fill color is taken from PageColor. For tiled high-resolution rendering, use RenderTile.
// Render current page to a 600x800 bitmap
var Bmp: TBitmap;
begin
Bmp := PdfView.RenderPage(0, 0, 600, 800);
try
Bmp.SaveToFile('page.bmp');
finally
Bmp.Free;
