how creating the Task to retrive gif file

gunse

Hi ,

What are the primitives need to add in Task to retrieve gif image with 128x128 dimension .

I added the following primitives in Task
Image Size
GIF Encoder

In Image Size primitive i mentioned print size (width=128 pixels and Height=128 pixels)

After i tried to download the gif image in Mediabin using the above Task i am getting the following error msg
" Exception in Primitive {82637480}! Reason = FwdDescriptor bad in ForwardSetup, Message = Image Sizer error: unsupported colorspace. "

It works fine If i removed the Image Size primitive in Task but original dimension.

What are the primitives need to add to retrieve gif with resized dimension(128x128).

Files in GIF format have to be indexed color. Unfortunately the server cannot resize indexed color files directly. Therefore, your task ideally should include:

1) Color converter to convert from original colorspace to RGB.

2) Resize primitive.

3) Color converter to convert to IndexedRGB

4) GIF Encoder

To be completely general you may want to add a primitive 0) which is a flattener. That should take care of the possibility that the original file had multiple layers.

The one snag in the above recipe is that we do not allow resizing animated GIF's.
