Previewing graphics

Any text or object to be exported with anti-aliased edges will be

displayed with its edges softened artificially. It is worth turning on

the Graphics Preview to see a more accurate view of your page

while you’re creating it. It uses a bit more memory than normal to

display the page, and slows performance slightly, though it’s not

normally noticeable.

When you import any graphic (with the exception of images

imported as “pass-through”—see Pass-through graphics on page 105),

Freeway uses the original as a basis for a completely new exported

version. In the process, Freeway offers you precise options that can

be used to adjust the compression, interlacing, color palette, and

number of colors in the resulting exported graphic. However, these

options may have a profound effect on either the final file size, the

appearance of the resulting image or both; and it’s useful to have

feedback on these two factors when adjusting the options provided.

When adjusting images with the Inspector palette’s Item Output panel graphics controls, in order to preview the effect of your

changes in real-time, the Graphics Preview command can be used. When you turn on Graphics Preview, all the graphics in the page

go through the entire export process and are then displayed for you in position on the page, just as they would appear in the browser.

Graphics previewing can take a few seconds, depending on the processor speed of your Mac, during which time a “checkerboard”

pattern may be displayed over graphics being processed. Graphics are displayed individually after they have been processed. Using the

Item Output panel of the Inspector palette, you may adjust the image controls. When you change an option, the graphic will be

updated and redrawn. Significant changes, such as changing from GIF to JPEG or panning the graphic within its box, may cause the

display to temporarily revert to the checkerboard pattern again. Once the graphic is displayed, the Size option in the Item Output

panel reports its exact size in bytes.

You can use Graphics Preview to help optimize images in your page. Turn on Graphics Preview, then make adjustments to the quality

level (JPEG), or number of colors used (GIF and PNG). You will see the effect of the adjustments in your page, so you can get the quality

set for the best looking image at the smallest overall file size.

At any point while Graphics Preview is calculating, it can be

interrupted—for example, to turn it off again, move elements,

or carry out any other action. However, once it has been

interrupted, it needs to restart the process from the beginning, if

you allow it to continue.

Graphics Preview requires quite intensive processing and can

use a fair amount of memory. It can also slow down your work

in Freeway to unacceptable levels (especially on older G3 iMac

and iBook computers), so it’s recommended that you only turn it

on when you need to work with the graphic output options and

turn it off again when you’re finished.

HTML layout

In Freeway, when working with table layouts (in Freeway Pro this means with the CSS button off), it is possible to place an HTML item

in front of a graphic item. When you do this, the HTML item slices the graphic item behind it, revealing the page background color or

background image—this is how the output will appear in a web browser.

Note: Freeway Express does not support CSS layers and works in table

layout mode only.

Upon publishing your site, Freeway slices the underlying image appropriately and exports it in sections, holding them together in

the HTML. The HTML text will expand in two directions to fill the

available space defined by the size of the HTML box. If the text

becomes too large in the browser, the area occupied by the HTML

box will expand. This can cause problems in some circumstances—as

the HTML box expands, it will force apart the cut segments of the

“underlying” image.

Enabling the HTML Layout option from the View menu can help

avoid this problem—Freeway displays the cuts made to images (if

any) as light blue lines; and where an HTML box may potentially

cause problems, the danger zone is indicated by red arrows. These

arrows indicate the areas where your design may break if the text size

used in the browser is too large.

If Graphics Preview is turned on graphic text will

appear blocky in page view when zoomed in for detailed work.

With HTML Layout on,

problem areas of overlapping

items that may break in a

browser are highlighted by

red arrows.
