[Opensim-dev] How to retreive pictures from the inventory ?

[Frisby, Adam]

It's a JPEG2000 image, Bitmap doesn't support J2C. There's a Utility method for converting to a Bitmap however. (not sure what it is)

Regards,

Adam

Thanks for your help, but I still have a problem, and I don't really know whats wrong. This is my code :

            AssetBase asset = scene.AssetService.Get(item.AssetID.ToString());
            byte[] byteArray = asset.Data;
            using (MemoryStream ms = new MemoryStream(byteArray))
            {
                Bitmap img = (Bitmap)Image.FromStream(ms);   <---------   error, parameter is not valid
            }

It seems that my MemoryStream is not valid, and I think it's because the byte array is not correct to convert to Image. But the object I retreive is an image, so I don't understand what's wrong. OpenSim does modification of this array ?

Thank you a lot,
Valentin

Hi Valentin

If you look at the Rest application plug-in, it supports the retrieval and uploading of inventory data, both catalog data and the assets themselves.

[Opensim-dev] How to retreive pictures from the inventory ?


________________________________


Dear all,

I'm working on a project where I have to process images, using another application, and then display something in OpenSim. I would like to let users to upload their pictures on OpenSim, but I have to retreive these pictures, and copy them in a special directory.
My problem is in the code of OpenSim, I only can find how to retreive an InventoryItemBase from the inventory, but I didn't find any way to retreive a picture, to be able to copy it.
Does someone know how can I retreive pictures from the Inventory, but not as an InventoryItemBase, but as something I can use as a picture ?

Thank you a lot for your help,
Best regards,
Valentin Castan_______________________________________________
