Hi,
Thanks for the prompt reply and your input. One problem of not being able to draw the scaled object is because of the unknown width and height of the image returned from the server. The image is a binary file which I used gettofile urltransfer method to store it directly to tmp:/ storage and then display it by point the url to the tmp:/ storage. In this case, since I do not know the width and height of that image, how can I determine the scale of the object?
If I was to put the image in roSlideShow, it has no problem of putting the image to its scale option. I guess if my question can be more specific on how does the roSlideShowScreen determine the width and height of the image and scale it to the right size.
Thanks.
