A PDFReader Demo for .NET MAUI
A PDFReader demo for MAUI currently implements the following functions:
- PDF documents opening and closing.
- PDF pages rendering and displaying.
- PDF pages flipping and jumping.
- PDF pages zooming in and out.
Third-party nuget package needed
- SkiaSharp Used to convert the rendered foxit.common.bitmap into an SkiaSharp.SKImage.
- System.Drawing.Common Required by the Foxit.SDK.Dotnet.
Render a PDF page to Microsoft.Maui.Graphics.IImage
The following codes show how to convert foxit.common.bitmap to Microsoft.Maui.Graphics.IImage.
using IImage = Microsoft.Maui.Graphics.IImage;
...
foxit.common.Bitmap bitmap = new foxit.common.Bitmap(bitmap_width, bitmap_height, foxit.common.Bitmap.DIBFormat.e_DIBArgb);
foxit.common.Renderer render = new foxit.common.Renderer(bitmap, false);
foxit.common.fxcrt.Matrix2D matrix = pdf_page_.GetDisplayMatrix(cx, cy, width, height, rotate);
bitmap.FillRect(0xFFFFFFFF, null);
// Render page
render.StartRender(pdf_page_, matrix, null);
int pitch = bitmap.GetPitch();
IntPtr ptr = bitmap.GetBuffer();
SkiaSharp.SKImage sk_image = SkiaSharp.SKImage.FromPixels(new SkiaSharp.SKImageInfo(bitmap_width, bitmap_height, SkiaSharp.SKColorType.Bgra8888), ptr, pitch);
var data = sk_image.Encode();
Stream stream = data.AsStream();
MemoryStream mem_stream = new MemoryStream();
stream.CopyTo(mem_stream);
IImage image;
#if WINDOWS
W2DImageLoadingService w2d = new W2DImageLoadingService();
image = w2d.FromStream(mem_stream);
#endif
#if IOS || ANDROID || MACCATALYST
image = PlatformImage.FromStream(mem_stream);
#endif
