«

I have been been searching the Web, trying to find a way of resizing images
while retaining the original aspect ratio. I know I can use 'height' and
'width', but finding out the necessary values for many images is laborious.
Is there an equivalent (with or without CSS) to 'scale' in LaTeX? For
example <img scale="80%" src="myimage" />?

Thanks in advance,

Roy

Even a basic image editing program should be able to handle that.

Yes, but resizing images in HTML is a bad idea anyway. Use a proper
image editor.

Although it is not a perfect analogy, it is similar to saying "I can make
this Web page in Word and it looks okay on my computer". I want to use the
powers of HTML/CSS rather than editing images.

But that's done off-line. What if I want to have one image displayed in two
different forms (sizes) without duplicating? Also, resizing in the usual
way involves no smoothing.

Your original request bears more similarity to that analogy than my
answer does.

It's like saying you want to display the image with a yellow background
instead of blue using HTML and CSS. The height and width of an image are
an intrinsic part of the image itself, and thus are best changed in a
program designed for that purpose.

Well not necessarily, but in most cases it is, yes.

Upload 2 copies of the image in different sizes.

You only upload the smaller one and put up with the ugly enlargement. Or
you only upload the larger one, and anyone on dialup will hate you
because they have to download the larger file, even if they are only
looking at the smaller one.

Set a width and the height will automatically adjust itself.

I read the original message again. I struggle to see how it is so, but like
I already said, it was not a good analogy. It's the use of a program that
is not ideal for the job...

One could argue that a better environment should intergrate Web design with
graphical design.

Good point. I might try that.

<sigh> The point was *not* to do that. Neither option is a good one. The
best option is to change the image itself. There are various automated
tools available if you have a large number of images you don't want to
do manually.

If you want to have two different sized images, use the smaller one to
link to another page that contains the larger one. Use text to explain
that clicking the image will load a larger file. That way anyone who
doesn't want to waste the bandwidth doesn't end up downloading the
larger one.

Or use text links that point to each one. Then the person viewing the
page can choose which to see.

Maybe provide a much smaller thumbnail on the first page with the two
links below them as below:
______
| |
| |
| |
| |
|______|
Link to small image
Link to large image

Why? Why not integrate a web design tool with a relational database
management system instead? Or with a document version management tool?
Either would make just as much sense.

Do it with the appropriate software. Here's why: if you image is
600x600 pixels and weighs 200k, "scaling" it in HTML or CSS will simply
result in the download of a 600x600 pixel, 200k image being displayed
poorly. The poor sucker at the end of the line still has to download
the image at full size.
