Using Image Preview
When accessed through the Export Wizard, the Image Preview displays recommended optimization and export options for the current document. When selected directly from the File menu, the Image Preview displays the current document export settings as defined in the optimize panel.
The preview area of the Image Preview displays the document or graphic exactly as it will be exported and estimates file size and download time with the current export settings.
You can use split views to compare various settings to find the smallest file size that maintains an acceptable level of quality. You can also constrain the file size using the Optimize to Size wizard.
When you export animated GIFs or JavaScript rollovers, the estimated file size represents the total size across all frames.
NOTE |
To increase redraw speed of the Image Preview, deselect Preview. To stop the redraw of the preview area when changing settings, press Escape. |
