Text and Image edit on Canvas with save as file - windows-phone-8

Question

I am working on an application, in which there is requirement for one page where user can
Add/Edit text on canvas and save as file to print/edit it again.
For example:
Add text to canvas, change its fonts, color, size, etc.
Later I want to add option for inserting the image on canvas.
It is just like MS Paint which is quite big software,here I just need simple canvas, under that a stack panel where I want to add options to edit text (color palette, size, & font).
Please help me out with suggestions & examples. It is not mandatory to use canvas. My objective to text/image edit page, save as file, and editable again.
Thank you in advance.

To save text to a file for later use, use a textBOX and isolated storage. A canvas is mostly to work with shapes, images, and other graphics controls.
Say you have a textbox named box in xaml.
XAML
<Textbox x:name="box" />
This code below could be in some kind of save click method when a button is clicked.
C#
using (IsolatedStorageFile isoFile = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream isoStream =
new IsolatedStorageFileStream("box.txt", FileMode.Create, isoFile))
{
using (StreamWriter sw = new StreamWriter(isoStream))
{
sw.Write(box.Text);
}
}
}
