204 Images, Animation, and Multimedia
• Any image you inserted as a GIF, JPEG, or PNG is exported as the
original file, using its original file name.
• Inserted metafiles and all other graphics are regenerated as PNG
images.
You can alter these settings, but before doing so you should review the "logic"
WebPlus applies to publishing web graphics. First, WebPlus has one default
format to which all graphics will be converted on export—but you can make
exceptions to this rule by specifying that certain image types should remain as
their original file. Initially, PNG is the default format, but with overrides set for
GIFs and JPEGs. That's why, using the initial settings above, GIFs stay as they
are while all other graphics get converted to PNGs.
You can check and change these settings in the Site Properties dialog (File
menu). The settings there are global and apply to all graphics in the site—but
again you can make exceptions, in this case for individual graphics. To do so,
for a selected graphic you could:
• Use the Image Export Options... (Format menu) or the Image
Export Manager (Tools menu) to set the export format of particular
images on a case-by-case basis.
- or -
Convert certain images to a specific format beforehand using the
Tools>Convert to Picture.
This combination of global and local settings gives you almost total control (if
you care to exercise it) over how your graphics make it onto your web pages!
Let's look first at how the global settings work.
To set global export options for web graphics:
1. Choose Site Properties... from the File menu and select the Graphics
tab.
2. In the Export File Format section, select a preferred export format.
This is the default format to which all graphics will be converted on
export unless you set overrides. For JPGs, you can set a compression
value. For PNGs, Use PNG transparency and Use compatibility
hack.. options allow PNG transparency and properly render PNG
alpha transparency (in Internet Explorer 5.5 and 6.0), respectively.
