image 'stretch' but maintaining aspect ratio

[Michiel Spape]

Hi,
E-Prime is, of course, not quite as convenient as current web-standards, but I see no reason it should be _that_ difficult to arrange. That is, if your images all need to be 500 pixels high, say, and your picture is 200x400, can't you just stretch it by 25% (i.e. width and height become 500/400=125%, or 250x500)? The only thing required is that you need to know the base size of your pictures prior to the stretching operations.
Two points, however: E-Prime stretches incredibly badly, it does no form of anti-aliasing whatsoever, so your pictures will become degraded in quality. A lot. Secondly, on that point, and given that it's still science-related, I think it is much better practise to do such things off-line (in photoshop or whatever) - keeping the quality somewhat high and knowing full well in advance what you're going to get. It's a bit of work, but well worth it, generally.
Cheers,
Mich

Subject: image 'stretch' but maintaining aspect ratio

Hi all,

My research indicates that the answer to my question is 'No' but I
thought I'd try a quick post incase someone has found a way to do
this.

I want to display images without altering the aspect ratio (ie width
to height proportions) but to fix one of the dimensions, e.g. height
and leave eprime to set the appropriate width so that the image
doesn't get stretched/squashed. (easy in css but I haven't seen how it
can be done in eprime)

Any thoughts?

Many thanks,

John
