Garmin, new API idea: Read a pixel color from bitmap

Hi all,

I would like to ask Garmin & ConnectIQ that support a new API for read a (or more) pixel color from bitmap resource.

I can say it would be a great help for many developper. Manipulation, scale, etc a bitmaps.

Is it a hard way? I think no, because it is just a read from the bitmap color array, or I am wrong.

Thank you!

Peter

    I have had some success using base64 encoded images to read pixels, but of course this won’t work with images downloaded via makeImageRequest.

    Yes, definitely!
    Or you can read "binary" data from the built-in images, because there is not other way to do it. (just json text, but it has much more memory required)
    Or simple image color manipulation.

    Yes, I know, it could trigger the watchdog, but I can do it more "step" (e.g. draw 10 pixel every frame) in a BufferedBitmap...

    An example of a possible use case that would not trigger the watchdog: read a raster image from the web and sample a single pixel that signifies something e.g. weather map storm intensity at specified location.
