Resizing images - portrait and landscape

Question

Hi,
I am uploading and resizing images(see code), I want to
resize them to 200px by 150px if landscape and 150px by 200px if
portrait. How can I determine the orientation of the image?

Well, first of all you would need to know what the initial
image dimensions are. And the way to do this is to get the current
images height and width from reading the image. You would then
compare the width number to the height number and if the width is
greater than the height, you know that it's more of a landscape
photo...and vice versa.
Try this code:
<cfimage action="read"
source="#expandPath("graphics/corner.png")#" name="myImage" />
<cfdump var="#variables.myImage#" />
<cfif variables.myImage.width gt
variables.myImage.height>
Landscape
<cfelseif variables.myImage.width lt
variables.myImage.height>
Portrait
<cfelseif variables.myImage.width eq
variables.myImage.height>
Square
<cfelse>
Something else for whatever reason.
</cfif>
At least, I think this is how you'd do it. I know it's not
the most elegant way...you might want to look at ColdFusion image
functions rather than reading the whole image in, I think there are
functions just to get width and height, which I imagine should give
you better performance.
Good luck,
