This WebDNA talk-list message is from 1998
It keeps the original formatting.
numero = 17217
interpreted = N
texte = Does anybody know of a way within WebCat, or via AppleScript, to get thewidth and height of an image (jpeg and/or gif)?In the application I'm developing, the user selects an image from a[listfiles]-generated pulldown list as part of a form. The next page putsthat choice into a database for later use in rendering html pages. Fordisplay reasons, I need to include
![]()
height and width in these pages.Because I perform a number of calculations based on these values, they needto be kept in fields in the database as well. Currently the user has tospecify a height and width for the image, but I'd really like to be able toautomate this.FYI, a separate database with width and height for each image is not anoption: I would like to eliminate the need for a person to ever manuallyenter those numbers.Any ideas?o--------------- Dave MacLeay --+o----------- Digital Frontier --+o--- dave@digitalfrontier.com --+
