display actual size of scanned images

[whirlpool6]

hello guys.

i am making a web application which displays scanned images. now, our client wants to view images just as big as what they are supposed to be originally i.e. they want to see A4 size images for the A4 documents and A3 for the A3 sized documents.

if only there is a way to get the dpi of the images using javascript or css or any client side way, this would only be a matter of scaling.

is there a way to get the image dpi using javascript?

or do you have any other suggestions as to how this can be done?

please do help. it is badly needed. thank you very much

Not a job for javascript. Hit the forum for whatever server-side technology you have at your disposal.

thanks for the reply.

looking for a server side solution for this will really slow down the system. is there any other client side solution for this? using css, or windows filters perhaps?

thank you very much?
