You could combine your silverlight project with XNA and use spritebatch.Draw().
It has a parameter for source rectangle, which lets you draw a part from the image.

MSDN has some help for how to combining silverlight and XNA.

Combine ScaleTransform and TranslateTransform to render the correct section.

ScaleTransform (numXTiles,numYTiles)

Translate (xTileIndex / numXTiles, yTileIndex / numYTiles);

Place the ImageControl inside a Grid to do the clipping

<a href="http://writeablebitmapex.codeplex.com/" rel="nofollow">WriteableBitmapEx</a> is compatible with Windows Phone and has a <code>Crop</code> method to do exactly that. You just need to do the math to figure out how wide/tall and X/Y coordinates to crop at.

<pre><code>//this creates the four quadrants of sourceBitmap as new bitmaps

int halfWidth = sourceBitmap.PixelWidth / 2;
int halfHeight = sourceBitmap.PixelHeight / 2;

WriteableBitmap topLeft = sourceBitmap.Crop(0, 0, halfWidth, halfHeight);
WriteableBitmap topRight = sourceBitmap.Crop(halfWidth, 0, halfWidth, halfHeight);
WriteableBitmap bottomLeft = sourceBitmap.Crop(0, halfHeight, halfWidth, halfHeight);
WriteableBitmap bottomRight = sourceBitmap.Crop(halfWidth, halfHeight, halfWidth, halfHeight);
</code></pre>

I might be off by a pixel (didn't test) in my above example, but it should demonstrate the API.

I want to split an image into several smaller images using silverlight for windows phone 7.5.

First of all, i want to know if this is even possible (i had some unpleasant surprises with windows phone APIs lately), and if it is, just give me some example as i have been able to find exactly none.

Thank you for your help.

我想使用windows phone 7.5版的silverlight将一个图像分割成几个较小的图像。首先，我想知道这是否可能(我最近在windows phone APIs上遇到了一些令人不快的惊喜)，如果是的话，请给我一些例子，因为我完全找不到。谢谢你的帮助。
