Hello! I saved an image onto the SD card via a camera. I would like to use the re-size and rotate functions from the Bitmap Class, instead of writing them myself doing it line for line... I understand it's not included in the microFramework because it also includes GUI functions that are useless on a netduino(right so far?) - Are there any substitutes for the Bitmap class? - Would it be more efficient and faster to write the code myself? - How can I create a Bitmap file out of my raw image... any ideas? Thanks in advance!

Emence,

I can't help you much, still relativly new to the Netduinos.

But you may want to look at the Netduino Go and the RGB display module from Nwazet.com. It will display pictures loaded from a SD card. RGB Display with Touch Screen.

In any case Fabien Royer would be able to answer most of the questions on using pictures and images.

Thanks for the link! I looked through the code. they are also using the Bitmap class to read the image. Seems like that is possible with the netduino GO. I actually don't want to display the image, just process it. :) I want to rotate and re-size my raw image and make a bitmap from it.
