Positioning Choose an option for page-element positioning as explained in
for HTML" on page 379.
InDesign Margins Select Maintain if you want the HTML file to have the same margins as
your InDesign document. If you select None, the InDesign margins are discarded and the
browser uses its own default margins.
Navigation Bar When you export an InDesign document as multiple HTML files, this
option creates navigation links on each page. The links open next and previous pages.
Select Top, Bottom, or Both depending on where you want the navigation links to appear.
If you don't want InDesign to create any navigation links, select None.
Setting graphics options
Choose Graphics at the top of the Export HTML dialog box to determine how InDesign
converts graphics elements for your HTML file. The options under GIF Settings and JPEG
Settings apply to all images converted during the export process.
Save Images As Lets you choose whether the individual graphics in your document
are converted to GIF or to JPEG. You can select Automatic to let InDesign choose which
of these two formats to use in each instance. The Automatic setting converts RGB,
CMYK, LAB, and grayscale images to JPEG, and indexed-color images or images with
transparency to GIF. Nonstandard text is converted to GIF, unless the text includes
inline images.
Whichever option you choose, linked images already in the GIF, JPEG, or PNG formats with
a 72-dpi resolution are exported without any conversion. This maintains any GIF animation
or transparency in the linked images and also maintains the quality of JPEG images by not
adding additional lossy compression. On the other hand, all embedded images—even
those saved as GIF, JPEG, or PNG— are converted to the format you choose.
Use Images Subfolder Creates a folder called Images within the folder where your HTML
documents are saved. InDesign stores image files for your HTML documents in that new
Images folder. This is a useful way of managing files, particularly if your HTML file is likely to
include a large number of images. If you don't select this option, all images are stored in
the same folder as your HTML files.
Palette Lets you control how InDesign handles colors when creating GIF files for your
HTML pages. The use of a limited color palette is required by the GIF format, which cannot
include more than 256 colors. Select from the following options:
Choose Adaptive (no dither) to create a palette using a representative sample of colors
•
in the graphic without any dithering, or mixing of small spots of colors to simulate
additional colors. This option often creates large areas of solid color, but the visual
effect varies with the type of graphic. The results may be undesirable for multicolored
photographs but suitable for cartoons, logos, maps, or computer screen-shots.
Generally, the Adaptive (no dither) option gives the best image quality for graphics
containing more than 256 colors; otherwise, choose Exact.
Choose Web to create a palette of the Web-safe colors that are a subset of the Windows
•
and Mac OS system colors.
Choose Exact to create a palette using the existing colors in the graphic. If a graphic
•
contains more than 256 colors, an alert message warns you that InDesign is unable to
create an exact palette.
