    SLARToolkit Error:- Only 32 Bit ARGB pixel format is supported, not Format32bppArgb

    Hi,
    Has anyone tried this SDK http://slartoolkit.codeplex.com/wikipage?title=Markers

    I am getting the error : Only 32 Bit ARGB pixel format is supported, not Format32bppArgb

    After a search got something similar but didn't solve my issue, http://stackoverflow.com/questions/1...ormat32bppargb

    Any suggestion please.

    Are you using this on a Windows Phone project? Do you have any sample code of what you are trying to do?

    I would also recommend you to download the latest source code and run the project against it and see if you can debug the error. It seems to me that you are using a format that is not suported by the tooklit what means that you will need to find a way to convert it to the proper format.

    Never used that library but I would also recommend posting the same question on the discussions section of the project: http://slartoolkit.codeplex.com/discussions

    Hey thanks,
    I got it working now. I select a wrong lib.
    By the way, I see that XNA code gives much accuracy then that of the Silverlight code. Silverlight code detects markers even if there is no marker at all.

    Do you know can I create .pat file from regular image. The doc says the image should have a black rectangle border.

    Does anyone know is there any Windows Phone AR SDK that recognized marker-less images, I mean to say not only the images that has a black border, rather any type of color image.
    I am looking for a similar SDK like this for windows phone.

    Any suggestion please.

    Not sure about "marker-less images" but these are the ones that I know of. Again. never worked with them so i'm not sure if it suits your needs.

    Thanks João,
    http://goblinxna.codeplex.com/ is for XNA and I was looking for pure Silverlight, and http://gart.codeplex.com/ plots location on viewfinder, its like the Nokia city lens.
    But must try http://goblinxna.codeplex.com/ so see if it supports Marker less images.

    By "Marker-Less" image I mean any type of color image, http://slartoolkit.codeplex.com/ can't recognized any type of images, it can only detect images that are having a black border around. Black & white image are recommended, color images doesn't give that much accuracy.
