Auto rotate bug?

Jellby · 01-31-2008, 05:17 AM

Hi all,

I'm new in these forums, I just received my Cybook Gen3 a couple of days ago (so far, I like it very much, but I miss some features).

I've found a problem with the auto rotate feature for pictures, it's not working at least with one of them. I loaded this picture: http://www.artchive.com/artchive/e/e..._ascending.jpg in the Cybook, but it insists in showing it in landscape orientation, I can manually change to portrait, but if I set it to auto rotate, it goes back to landscape. Apparently other pictures are fine, at least the pre-loaded ones.

Has anyone found the same problem? Any solution?

Sorry for the bump. Has no one experienced this?

Just to say that the new firmware did not solve this issue. But no one has confirmed it yet, anyway.

It is wrongly orientated for me also with new firmware. But how is autorotate supposed to work? If it looks at the exif tags then the exemple file does not contain any exif information so it should not work.

I would assume it should just check the width and height of the picture: if the height is larger than the width, it's portrait, otherwise it's landscape. That's at least how I expect it to work. Since the Cybook is so easy to turn one way or the other, I don't think it should care about exif tags, anyway.

Is there perhaps something wrong with the file header of the particular image that's causing the problem? It seems odd that it should fail for a particular image and yet work for others.

It seems it's the aspect ratio, it's not "large" enough. Converting to other formats or resizing the image does not solve it, but cropping it to 600x800 or to 200x600 does. If I take another image and resize it to 667x849 (the problem image size), it shows the same problem. The same if I create a completely new image with this size.
