Imagine being able to make a picture 10%
bigger without having to remake it in Photoshop
Yes of course - That would speed things up -
but why not use Graphic/scale up/down for small
changes and Modify for large ones?
All does the same thing!
Still, one might have to back to the original
file for large size increases though to keep it
clean as resampling a tiny GIF upward can only
go so far…
Resampling upwards should only be taken to the
point where you match your actual original image
pixels with the final output pixels. If you scale
a bitmap graphic larger than screen resolution
(the 1:1 relationship between its pixel grid and
the display pixel grid) you’ll end up with
softer, cruder final results.
New Freeway users should read this carefully…
The big difference to remember with Freeway is
that you can import images that have a higher
‘pixel density’, or pixel-per-inch resolution,
than traditional web designers are used to
having. Freeway recalculates the image when it is
output, building the ‘screen-res’ and
web-optimised graphic on the fly.
Imagine you have an image that is 900 pixels
across, and has a ‘pixel per inch’ setting of
300ppi. In print, that image would take three
inches of space on the page.
If dropped into Dreamweaver or referenced
directly in HTML code (assuming it is a suitable
format already) it would fill a 900 pixel-wide
space in a page. But imported into Freeway, it
takes the equivalent of three inches on the
design page, because Freeway understands about
pixels per inch settings in images.
When published from Freeway, that image is
generated at the precise pixel size required to
fill that ‘3 inch equivalent’ space in the web
page… which would be 216 pixels, to be precise.
But if you wanted to scale that graphic up, say
to six inches across, you can. Freeway simply
recalculates and regenerates the image when it
publishes, reading from the original source file,
and produces a 432 pixel wide graphic.
This provides a massive convenience. As long as
you don’t scale up past the 1:1 pixel scale
you’ll be fine. And for scaling down, this is
just as convenient. As noted before, if you find
yourself scaling down a lot then perhaps it is
time to scale the image externally, at least to
where you’re not doing sub-5% sizes of the
original!
Okay, having said that, you may prefer to do
scaling yourself in Photoshop. If you know the
final pixel dimensions that you need, scale to
that, using Bicubic Sharper in Photoshop’s Image
Size dialog. If necessary, apply further
sharpening (but not too much or things look
artificial), then save (as Photoshop or TIFF, or
PNG-24 if using Freeway Express) and import as
before.
Oh, if you do this you might as well set the
pixel per inch value to 72ppi while you’re in the
Image Size dialog. If not, you’ll just need to
scale the image to fit your box in Freeway. The
final result will be fine; Freeway will
recalculate the image and the result will look
clean, as long as the pixel size is right, but
why not save yourself that step if you’re going
to the bother of resizing in the first place?
Merge could be useful too, new things to work with for sure!
Yep. Try taking a few different graphics, each
with transparent areas. Save as Photoshop,
import, overlap, and have fun building your
composite graphic. If the items are unlayered,
either loose on the page or grouped into a single
parent container layer, then they’ll be merged
(combined) into a single graphic in the published
output.
One of the many benefits is being able to arrange
graphic elements in situ, right there in the page
layout. Another is being able to rearrange items
on the fly with no resaving and reimporting
required.
