I create a custom image in my app (by capturing ink data for example) and then want to show the generated image on Live Tile. How can I do this?
all you need to do is assign the image to the live tile template.
TileUpdateManager.GetTemplateContent(TileTemplateType.TileWideImageAndText01);
XmlNodeList tileTextAttributes = tileXml.GetElementsByTagName("text");
tileTextAttributes[0].InnerText = "Hello World! My very own tile notification";
XmlNodeList tileImageAttributes = tileXml.GetElementsByTagName("image");
((XmlElement)tileImageAttributes[0]).SetAttribute("src", "ms-appx:///images/redWide.png");
((XmlElement)tileImageAttributes[0]).SetAttribute("alt", "red graphic");
XmlDocument squareTileXml = TileUpdateManager.GetTemplateContent(TileTemplateType.TileSquareText04);
XmlNodeList squareTileTextAttributes = squareTileXml.GetElementsByTagName("text");
squareTileTextAttributes[0].AppendChild(squareTileXml.CreateTextNode("Hello World! My very own tile notification"));
IXmlNode node = tileXml.ImportNode(squareTileXml.GetElementsByTagName("binding").Item(0), true);
tileXml.GetElementsByTagName("visual").Item(0).AppendChild(node);
TileNotification tileNotification = new TileNotification(tileXml);
tileNotification.ExpirationTime = DateTimeOffset.UtcNow.AddSeconds(10);
TileUpdateManager.CreateTileUpdaterForApplication().Update(tileNotification);

I just registered. I try to address the following case:
Given a basic pdf (a simple, single raster image), I want to get to:
Create a pdf (empty initially), in which I create a layer, in which I embed the raster image of the input_pdf, and mark said layer as visible and not_printable.
Are there tools to do it?
Thanks for the tips.
Since you do not specify a language or a library you use, here it is a solution in C#:
// Extract the page content from the source file.
FileStream stream = File.OpenRead("input.pdf");
PDFFile source = new PDFFile(stream);
PDFPageContent pageContent = source.ExtractPageContent(0);
stream.Close();
PDFFixedDocument document = new PDFFixedDocument();
document.OptionalContentProperties = new PDFOptionalContentProperties();
PDFPage page = document.Pages.Add();
// Create an optional content group (layer) for the extracted page content.
PDFOptionalContentGroup ocg = new PDFOptionalContentGroup();
ocg.Name = "Embedded page";
ocg.VisibilityState = PDFOptionalContentGroupVisibilityState.AlwaysVisible;
ocg.PrintState = PDFOptionalContentGroupPrintState.NeverPrint;
// Draw the extracted page content in the layer
page.Canvas.BeginOptionalContentGroup(ocg);
page.Canvas.DrawFormXObject(pageContent, 0, 0, page.Width, page.Height);
page.Canvas.EndOptionalContentGroup();
// Build the display tree for the optional content
PDFOptionalContentDisplayTreeNode ocgNode = new PDFOptionalContentDisplayTreeNode(ocg);
document.OptionalContentProperties.DisplayTree.Nodes.Add(ocgNode);
using (FileStream output = File.Create("EmbedPageAsLayer.pdf"))
{
document.Save(output);
}
The output PDF file is available here: https://github.com/o2solutions/pdf4net/blob/master/GettingStarted/EmbedPageAsLayer/EmbedPageAsLayer.pdf
In Xamarin.Forms, I want to convert my xaml page UI (sometimes my page is scrollable when having more content) into the PDF. I have tried the PDFSharp (https://github.com/akgulebubekir/PDFSharp.Xamarin.Forms) open source. But it works only on UWP and having some issues in iOS and Android.
So is there any free open source plugin available to convert XAML UI into PDF in all three platforms? If open source not available, is there any other way or work around to achieve it in android, ios & UWP?
Thanks in advance.
I had a bit of trouble with this and managed to do it using UIkit and PdfKit tools.
Here is an exemple:
using UIKit;
using PdfKit;
//Calculate scroll View height
double xamlHeight = XamlFullPage.Height;
int numberOfPages = (int)Math.Ceiling(xamlHeight / Application.Current.MainPage.Height);
// Create a new PDF document
PdfDocument document = new PdfDocument();
for (int i = 0; i<numberOfPages; i++) //while the all the page have not been taken into account
{
await SummaryScrollView.ScrollToAsync(0, i*Application.Current.MainPage.Height, false).ConfigureAwait(false); //find the beginnig of the current page
//Captures the XAML page as image and returns the image in memory stream
var image = UIScreen.MainScreen.Capture();
// Create a page with the printscreen
PdfPage page = new PdfPage(image);
//insert page in the i position
document.InsertPage(page, i);
page.Dispose();
}
//Write file in temp foleder
document.Write(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "TuitionFees" + fileName + ".pdf"));`
I am trying to show an Image and text on windows phone. The text works but the image does not show up at all the docs on msdn says that it should though
here is my code ...
ToastTemplateType toastTemplate = ToastTemplateType.ToastImageAndText02;
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(toastTemplate);
XmlNodeList toastTextElements = toastXml.GetElementsByTagName("text");
toastTextElements[0].AppendChild(toastXml.CreateTextNode("Hello World!"));
XmlNodeList toastImageAttributes = toastXml.GetElementsByTagName("image");
((XmlElement)toastImageAttributes[0]).SetAttribute("src", "ms-appx:///assets/Square71x71Logo.scale-240.png");
((XmlElement)toastImageAttributes[0]).SetAttribute("alt", "red graphic");
ToastNotification toast = new ToastNotification(toastXml);
ToastNotificationManager.CreateToastNotifier().Show(toast);
Results
Expected Results
Image Square71x71Logo.scale-240.png
You cannot include an image in a toast on Windows Phone 8.1. The template will always be the app's logo then two text fields.
This is documented near the top of the Toast Template Catalog documentation on MSDN.
I programming for Windows Phone 8.1. I use this way to create image and set source of image:
Dim AgreeBitmapImage As BitmapImage = New BitmapImage()
AgreeBitmapImage.setsource(New Uri("Assets/Image/Agree.png", UriKind.Relative))
//Above line gives an error
imgAccept = New Image
imgAccept.Height = 40
imgAccept.Width = 40
imgAccept.Source = AgreeBitmapImage
When I start the emulator, it doesn't work. Why? (Say error)
In Windows Phone 8.1, the resources like png should be get using ms-appx:
AgreeBitmapImage.UriSource =
New Uri("ms-appx:///Assets/Image/Agree.png", UriKind.Absolute)
How I can create PDF files from a list of image in WinRT. I found something similar for windows phone 8 here("Converting list of images to pdf in windows phone 8") But I am looking for a solution for windows 8. If anyone of having knowledge about this please share your thoughts with me.
Try http://jspdf.com/
This should work on WinJS, but I haven't tested it. In a XAML app you can try to host a web browser control with a jsPDF-enabled page.
ComponentOne has now released the same PDF library that they had in Windows Phone for Windows Runtime. Tho it's not open source, of course.
Amyuni PDF Creator for WinRT (a commercial library) could be used for this task. You can create a new PDF file by creating a new instance of the class AmyuniPDFCreator.IacDocument, then add new pages with the method AddPage, and add pictures to each page by using the method IacPage.CreateObject.
The code in C# for adding a picture to a page will look like this:
public IacDocument CreatePDFFromImage()
{
IacDocument pdfDoc = new IacDocument();
// Set the license key
pdfDoc.SetLicenseKey("Amyuni Tech.", "07EFCD0...C4FB9CFD");
IacPage targetPage = pdfDoc.GetPage(1); // A new document will always be created with an empty page
// Adding a picture to the current page
using (Stream imgStrm = await Windows.ApplicationModel.Package.Current.InstalledLocation.OpenStreamForReadAsync("pdfcreatorwinrt.png"))
{
IacObject oPic = page.CreateObject(IacObjectType.acObjectTypePicture, "MyPngPicture");
BinaryReader binReader = new BinaryReader(imgStrm);
byte[] imgData = binReader.ReadBytes((int)imgStrm.Length);
// The "ImageFileData" attribute has not been added yet to the online documentation
oPic.AttributeByName("ImageFileData").Value = imgData;
oPic.Coordinates = new Rect(100, 2000, 1200, 2000);
}
return pdfDoc;
}
Disclaimer: I currently work as a developer of the library
For an "open source" alternative it might be better for you to rely on a web service that creates the PDF file using one of the many open source libraries available.
I think this may help you if you want to convert an image (.jpg) file to a PDF file.
Its working in my lab.
string source = "image.jpg";
string destinaton = "image.pdf";
PdfDocument doc = new PdfDocument();
doc.Pages.Add(new PdfPage());
XGraphics xgr = XGraphics.FromPdfPage(doc.Pages[0]);
XImage img = XImage.FromFile(source);
xgr.DrawImage(img, 0, 0);
doc.Save(destinaton);
doc.Close();
Thanks.
