Struts, Some API to obtain wide and the high one of an image?

[Eric]

I am developing an application in Java with Struts, where in a screen I have to do an upload of an image, to detect if it is JPG, GIF or Flash (easy) and then to interpret the binary to

know the measures of the image.

I understand that they must exist librarys for this… this code is going to run in server, reason why does not interest to add a framework (awt, so on)

Hello,

ImageInfo—Java class to extract image file properties

it is of a class of java that already has everything codified to see the properties of the images, the only detail is that doesn't have support for formats flash (the man got tired to cover bugs).
