    since the documentation is a bit poor and I'm not willing to play around I simply ask it here.

    How does RadBinaryImage resize images?
    Does it use a "best fit" algorithm or does it simply "cut" the longer side?

    What I mean with "best fit" is that an image is sized in a manner that it is as large as possible without loosing it's aspect ratio.
    Max. Size 200, 200
    Given Image: 300, 180 -- scaled to 200, 120
    Given Image: 300, 400 - scaled to 150, 200

    Hello Manni,

    Actually both of them are available. As stated in the docs:

    ResizeMode Specifies whether the image should be sized automatically if Width and Height of the image are set in pixels. Possible values are:

    • Crop (the image will be trimmed)
    • Fit (the image will be sized to fit the given dimensions)
    • None (default)

    I hope this helps. 

    Sincerely yours,

    Can I resize the image on Uploading?
    I used this demo:

    User may upload a HUGE file, I want to save just a thumbnail in the database.

    Hi Sebastien,

    In order to achieve this, you should handle updating and manually modify (resize) the image's data before data is pushed to the DB. You may check this RadListView demo for an idea on how to hook and modify upload value  on update.

    Best wishes,
