Working with documents

Image Conversion Lets you choose whether the optimized images in your document are converted to GIF, JPEG, or
PNG. Choose Automatic to let InDesign decide which format to use in each instance. Choosing PNG disables the
image compression settings.; use PNG for lossless images or for images that include transparency.
GIF Options (Palette) Lets you control how InDesign handles colors when optimizing GIF files. The GIF format uses
a limited color palette, which cannot exceed 256 colors.
Choose Adaptive to create a palette using a representative sample of colors in the graphic without any dithering
(mixing of small spots of colors to simulate additional colors). Choose Web to create a palette of web-safe colors that
are a subset of Windows and Mac
OS system colors. Choose System (Win) or System (Mac) to create a palette using
the built-in system color palette. This choice may cause unexpected results.
Select Interlace to load the images progressively by filling in missing lines. If this option is not selected, an image looks
fuzzy and gradually becomes clear as the image reaches full resolution.
JPEG Options (Image Quality) Determines the trade-off between compression (for smaller file sizes) and image quality
for each JPEG image created. Low produces the smallest file and lowest image quality.
JPEG Options (Format Method) Determines how quickly JPEG graphics display when the file containing the image is
opened on the web. Choose Progressive to make the JPEG images display gradually and in increasing detail as they are
downloaded. (Files created with this option are slightly larger and require more RAM for viewing.) Choose Baseline
to make each JPEG file displays only after it has been downloaded; a placeholder appears in its place until the file
displays.
Ignore Object Conversion Settings Ignores Object Export Options applied on individual images. See “ Apply Object
export options ” on page 436.
EPUB Contents options
The Contents section of the EPUB Options dialog box includes the following options.
Format For EPUB Content Specify whether you want to use the XHTML or DTBook format. DTBook is a specialized
format that is intended for sight impaired end readers.
Use InDesign TOC Style Select this option if you want to generate a table of contents based on the selected TOC style.
From the TOC Style menu, specify the TOC style you want to use to build the table of contents in the eBook. You can
choose Layout > Table Of Contents Styles to create a special TOC style for your eBook.
Break Document at Paragraph Style You can split the eBook at the specified paragraph style. Splitting results in a
larger number of HTML files in the EPUB package, but can be helpful for breaking up long files and increases
performance in the EPUB readers.
Place Footnote After Paragraph Check to place footnotes after the paragraph. If deselected, footnotes are converted to
endnotes.
Remove Forced Line Breaks Check to remove all soft-returns in the exported eBook.
Generate CSS Cascading Style Sheets (CSS) are a collection of formatting rules that control the appearance of content
in a web page. When you use CSS to format a page, you separate content from presentation.
• Include Style Definitions When exporting to EPUB, you can create a list of CSS styles that can be edited.
• Preserve Local Overrides If this option is selected, local formatting such as italic or bold is included.
• Include Embeddable Fonts Includes all fonts that are embeddable, in the eBook. Fonts include embedding bits that
determine if the font is enbeddable.
Style Names Only Includes only undefined style names in the EPUB style sheet.
