    René Schulte has released to the marketplace a photo manipulation application called "Pictures Lab".

    Source: Kodierer

    Pictures Lab is the ultimate picture effects application for Windows Phone. If you like to take photos then this app is a perfect addition to your phone’s toolset. Or like msnbc.com wrote: "The app, a Swiss Army knife of photo tweaks".

    Pictures Lab comes with more than 20 controllable and easy-to-use advanced effects like different vintage and hipster-like effects, Tilt Shift (miniature faking), Lomo, Soften, Auto Adjust, Sharpen, Comic, Bulge, B & W, Sepia and many more.

    In this post, René Schulte demonstrates how to load an image from the picture library with the PhotoChooserTask and how to save a picture to the library. 

    I've built a Windows Phone 7 app that uses the WriteableBitmapEx library and lets the user draw on the WriteableBitmap surface. The app supports multi touch for drawing and the radius of the pen can be changed with the Slider control. An image from the phone's picture library can be chosen with the folder icon button and the floppy disk button saves the current image to the picture library. When the third button (download icon) is clicked, all pictures from the phone's library are loaded without further user interaction. The trash button clears the draw surface. 

  • Filled To The Bursting Point - WriteableBitmapEx

    0 comments  /  posted by  Silverlight Show  on  Jun 03, 2010 (4 months ago)
    Take a look at the new WritableBitmapEx release from René Schulte, which includes new fill routines, transformations and more.

    We're slowly getting to the first feature complete release of the WriteableBitmapEx library. The last version ( brought the parametric curves, optimizations and other features. This new version focuses on filling routines, transformations, bug fixes and more optimizations.

    The new Fill* extension methods are equivalent to the Draw* shape functions. The FillRectangle and FillEllipse methods use specialized implementations to get the best performance. FillPolygon and the other functions use a simple scanline conversion algorithm with the even-odd-rule. The implemented algorithm supports concave and convex shapes.

  • Matrix3DEx 1.0 - When PlaneProjection is Not Enough

    René Schulte has started a new open source project at CodePlex called Matrix3DEx, which is an extension library for the Silverlight Matrix3D struct.Image

    Most of the functionality I implemented in Matrix3DEx was originally required for another open source project I'm currently working on (hint, hint), and as you might know I also like to extend Silverlight's graphics functionality in a reusable manner. That's why I decided to extract the Matrix3D code into a separate open source project, add some more useful methods, document it and write a sample.

  • Real Time 3D Augmented Reality with Silverlight

    0 comments  /  posted by  Silverlight Show  on  Dec 21, 2009 (10 months ago)
    In this blg post René Schulte discusses real 3D Augmented Reality in Silverlight.

    In the Silverlight 4 Augmented Reality Proof Of Concept blog post I proved that it's possible to implement Augmented Reality applications with Silverlight 4 and the built-in webcam API. The proof of concept used an image showing a Silverlight logo that was attached to the tracked marker. With this blog post I'm back in this field, but this time with real 3D Augmented Reality in Silverlight!

  • Sharp Edge - Silverlight Parametric Pixel Shader

    0 comments  /  posted by  Silverlight Show  on  Aug 03, 2009 (more than a year ago)

    René Schulte explains in detail pixel shaders and the implementation of edge detection post processing effect.

    Silverlight pixel shaders could be written in HLSL and compiled with the DirectX shader compiler fxc. The produced binary file is then loaded with the Silverlight 3 PixelShader class. Quite easy huh? I must admit that I'm not a complete newbie to shader development. I even wrote some shaders with Shader Model 1.1 in the assembler shading language a few years ago, but haven't done it a while.
    For Silverlight 3 I've implemented an edge detection post processing effect. It's a parametric pixel shader, which performs a common image processing technique called convolution.

  • An Oscar Algorithm - Silverlight Real-time 3D Perlin Noise

    0 comments  /  posted by  Silverlight Show  on  May 28, 2009 (more than a year ago)

    René Schulte has posted his Silverlight 2 implementation of a three dimensional improved Perlin Noise algorithm.

    Perlin Noise could produce pseudo-random semi-natural textures with fractal characteristics and is mostly used for procedural image generation. The algorithm can be controlled with various parameters and is able to produce good looking cloud / sky, fire, smoke, wood or marble textures and height maps, just to name a few.
