Graphics Options

GoClick converts all graphical objects in a document to either GIF or JPEG format, depending on the
settings in this panel.

Convert these objects to images:
These settings give you control over which types of objects get converted to images. By default, all
graphics get converted. By default, when Page Layout is set not to use Cascading Style Sheets, text
that intersect graphics is identified and automatically converted to an image (this is necessary because
non-CSS HTML does not allow the overlapping of text and images).

Sometimes, you may wish to turn off conversion of some objects. For example, some documents
contain rectangular borders that surround text. To prevent the output of these borders, you may wish to
turn off the conversion of rectangles.

Why Some Text Becomes an Image

The conversion of text to images is a powerful feature and deserves further explanation. The original
HTML did not allow overlapping of objects at all. With the advent of Cascading Style Sheets,
overlapping objects are now supported. When GoClick is set to use Cascading Style Sheets for page
layout, text that overlaps graphics remains as text. Only rotated or horizontally scaled text must be

converted to graphics in that case. But when GoClick is set to use the older and less capable HTML
tables for page layout, all text that overlaps a graphic (as well as rotated or scaled text) is converted to
a graphic.

In HTML, all images must be rectangular. GoClick using HTML table layout thus calculates the
rectangles that surround every graphical object. If any two rectangles intersect, the objects are joined
and the image rectangle grows. If the rectangle that encloses a graphical object intersects text, that text
will be added to the image (even though the object itself may not have intersected the text). If you have
non-rectangular graphics in your document—or if you have graphical objects that overlap each other—
imagine for a moment a rectangle that encloses those objects. That rectangle will “capture” all text that
intersects or is contained by it.

Forcing Text to Become an Image
You can use the “text-capturing” feature of GoClick’s HTML table layout to your advantage by forcing
certain text to be converted to an image. Converting some text to an image may be desirable for logos,
equations, text drawn with a nonstandard font, or text that isn’t displayed to your satisfaction with
HTML. To force conversion, simply enclose the text within a white rectangle and send that rectangle
behind the text. Since the text and the rectangle intersect, the text will be converted to an image. Note:
this technique only works when you’re not using CSS for page layout. To force text to become an
image when using CSS, you need to scale the text horizontally or vertically (although not all
applications have this ability).

If you are using Microsoft Word, there is an easy way to force a block of text (or an equation) to
become an image. Simply set the background of the text to white. To accomplish this, select the text
with your cursor:

Then, using MS-Word’s “Borders and Shading…” format command, set the background of the
selection to White:

Anti-aliasing
Anti-aliasing smoothes out the “jaggies” in vector objects and text when they are converted to images.
It has no effect when converting “paint” images like scanned photos. To use anti-aliasing, click the
appropriate box. Anti-aliasing takes longer and requires substantial memory, but the images look
better. Anti-aliased text loses some of its contrast, however, so it is not good for small text.

File format
You have two choices of file formats: GIF and JPEG. GIF is more common and is best for small
images that contain 256 colors of less. JPEG is best for very large images that are composed of many
colors, such as scanned photographs.

JPEG allows different image quality settings. The higher the quality, the better the image—but the
larger the file. “Normal” quality is the default and should be sufficient for most images. You may
select a different quality setting from the “Quality” menu. Note: JPEG output requires Apple’s
QuickTime to be installed. If it is not installed, GoClick will ask you to first install QuickTime or
change the File format setting to GIF.
