Hi all,

Does anyone know if it possible to use Flowcode to access picture files on an SD card in whatever format - JPEG, PNG... whatever and send them to an LCD display. Something like a photo frame controller.

All the pics would be preloaded on the SD card I just wonder if Flowcode could actually do it.

Hi James,

Bitmaps are no problem. In fact Flowcode v7 has a component to load and draw bitmaps from the chips ROM memory.

Bitmaps via the SD card are also possible, see here for a v6 example of a photo gallery.

JPEG files are a different kettle of fish and I think PNG's probably are too.I would like to investigate JPEGs at a later date but I remember the maths for JPEGs being a bit nasty from my image processing lectures.

PNGs have multiple storage options, from pixel based bitmap styles to vector based resizable styles and so to support all types of PNG would be a pretty big task.
