You can reduce file size by downsampling bitmaps. Bitmaps are made up of pixels. When you downsample a bitmap, the number of pixels per line decreases. The decrease in pixels per line results in a decrease in file size. The Publish To PDF feature lets you downsample color, grayscale, or monochrome bitmaps individually.
To downsample color bitmaps
1 Click File, Publish To PDF.
2 Click the Objects tab.
3 Enable the Color check box.
4 Type a number in the Color box.
To downsample grayscale bitmaps
1 Follow steps 1 and 2 from the previous procedure.
2 Enable the Grayscale check box.
3 Type a number in the Grayscale box.
To downsample monochrome bitmaps
1 Follow steps 1 and 2 from the "To downsample color bitmaps" procedure.
2 Enable the Monochrome check box.
• Downsampling color, grayscale, or monochrome bitmaps is effective only when the resolution of the bitmaps is higher than the resolution specified in the Bitmap Downsampling section.
