Metatags
When Canvas creates an HTML file from a document, it uses meta
tags in the HTML file header to include data entered in the document
Properties dialog box. This data includes information such as Title,
Subject Keywords, Author, and Category from the fields on the Sum-
mary tab for the Canvas document.
How images are handled
Canvas uses compression and color reduction to optimize images for
faster display on Web pages. All graphic objects are exported as
RGB images either in GIF format or JPEG format. You have the
option to choose the image format or you may allow Canvas to
decide this option for you (see Image Options on page 14.208).
When you select Automatic from the Image format menu, Canvas
exports RGB Color and CMYK Color images as RGB (24-bit)
images using JPEG compression. Indexed mode images, which use a
maximum of 8 bits of color information per pixel, are exported in
GIF format. Black and White images are exported as Indexed (8-bit)
images. Canvas exports Grayscale images as Indexed 8-bit images or
JPEG-compressed RGB images, using the format that it determines
will produce the best results.
How slices are exported
If slices are available in the Canvas document at the time of HTML
export, then Canvas will design the document layout to conform to
the slices. Canvas will also accept an individual slices setting when
it renders and names the images (see Exporting Slices on
page 14.198 and Slicer Export Options dialog box on
page 14.198).
Note: Slices are used only when Table Layout is activated.
How animated GIFs and Web buttons are
handled
Animated GIFs are exported without changes. In other words, one
GIF file will be produced for each animated GIF object. One image
for each Web buttons state will be exported. This group of images
will be linked together using Java scripting.
You cannot overlap these objects in the Table Layout mode. If that
happens, then an Animated GIF or Web button will be rendered and
