Hi, I am looking for ideas on how to approach the following:
I have a form and part of that form is a FileUpload widget for an image. After uploading I need to do a few other things like create a thumbnail from the original. The original might be of any size but the thumbnail will result in a 50x50 pixel image. I am doing this now based on the assumption that the most interesting part of the image is the square starting at the upper left-hand corner of the original image and who's sides are the smaller of the original's height or width. This is a poor assumption for all images. What I would like to be able to do is upload the original image, create a smaller version of the original that my form / the image widget could then display. Part of the display would have a square "view port" that could be moved around the small version of the original image. Once the view port is "dropped" it would define a "crop" region that would then become the thumbnail. Does such a widget already exist? If not can you suggest how [or if] GWT could be used to create such a thing? I can display the image, I am not at all sure how to enable the view-port dragging. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
