示例1: DrawLayer
public override void DrawLayer(CALayer layer, CGContext context)
{
context.SaveState ();
context.SetFillColor (1.0f, 1.0f, 1.0f, 1.0f);
context.FillRect (context.GetClipBoundingBox ());
context.TranslateCTM (0.0f, layer.Bounds.Size.Height);
context.ScaleCTM (1.0f, -1.0f);
context.ConcatCTM (this.oParentController.currentPDFPage.GetDrawingTransform (CGPDFBox.Crop, layer.Bounds, 0, true));
context.DrawPDFPage (this.oParentController.currentPDFPage);
context.RestoreState ();
}
示例2: DrawLayer
public void DrawLayer(CALayer layer, CGContext context)
{
// fill with white background
context.SetFillColor (1f, 1f, 1f, 1f);
context.FillRect (Bounds);
context.SaveState ();
// flip page so we render it as it's meant to be read
context.TranslateCTM (0f, Bounds.Height);
context.ScaleCTM (1f, -1f);
// scale page at the view-zoom level
context.ScaleCTM (MyScale, MyScale);
context.DrawPDFPage (Page);
context.RestoreState ();
}
示例3: DrawLayer
public override void DrawLayer (CALayer layer, CGContext context)
{
// keep a copy since (a) it's a _virtual_ property and (b) it could change between filling and flipping
RectangleF bounds = view.Bounds;
// fill with white background
context.SetFillColor (1.0f, 1.0f, 1.0f, 1.0f);
context.FillRect (bounds);
context.SaveState ();
// flip page so we render it as it's meant to be read
context.TranslateCTM (0.0f, bounds.Height);
context.ScaleCTM (1.0f, -1.0f);
// scale page at the view-zoom level
context.ScaleCTM (view.Scale, view.Scale);
context.DrawPDFPage (view.Page);
context.RestoreState ();
}
示例4: Draw
/// <summary>
/// Draws the document page
/// </summary>
private void Draw(CGContext context)
{
if (!PDFDocument.DocumentHasLoaded) {
return;
}
// Draw page
context.SetFillColor(1.0f, 1.0f, 1.0f, 1.0f);
using (CGPDFPage pdfPage = PDFDocument.GetPage(mPageNumber)) {
context.TranslateCTM(0, Bounds.Height);
context.ScaleCTM(1.0f, -1.0f);
context.ConcatCTM(pdfPage.GetDrawingTransform(CGPDFBox.Crop, Bounds, 0, true));
context.SetRenderingIntent(CGColorRenderingIntent.Default);
context.InterpolationQuality = CGInterpolationQuality.Default;
context.DrawPDFPage(pdfPage);
}
}
示例5: DrawInContext
public override void DrawInContext (CGContext context)
{
// PDF page drawing expects a Lower-Left coordinate system, so we flip the coordinate system
// before we start drawing.
context.TranslateCTM (0, Bounds.Height);
context.ScaleCTM (1, -1);
// Grab the first PDF page
using (CGPDFPage page = doc.GetPage (1)){
// We're about to modify the context CTM to draw the PDF page where we want it, so save the graphics state in case we want to do more drawing
context.SaveState ();
// CGPDFPageGetDrawingTransform provides an easy way to get the transform for a PDF page. It will scale down to fit, including any
// base rotations necessary to display the PDF page correctly.
CGAffineTransform pdfTransform = page.GetDrawingTransform (CGPDFBox.Crop, Bounds, 0, true);
// And apply the transform.
context.ConcatCTM (pdfTransform);
// Finally, we draw the page and restore the graphics state for further manipulations!
context.DrawPDFPage (page);
context.RestoreState();
}
