Graphics
Deselect this option if you’re using a proxy-based workflow and plan to have your service providers perform the image
replacement using their OPI software. When this option is deselected, InDesign preserves the OPI links but does not
read them. When you print or export, the proxy and the links are passed on to the output file.
Select this option if you’re using a proxy-based workflow and you want InDesign, instead of your service provider, to
perform image replacement when you output the final file. When you select this option, the OPI links appear in the
Links panel.
Also select this option when you import EPS files containing OPI comments that are not part of a proxy-based
workflow. For example, if you import an EPS file containing OPI comments for an omitted TIFF or bitmap image,
you’ll want to select this option so that InDesign can access the TIFF information when you output the file.
Apply Photoshop Clipping Path Regardless of whether this option is selected, a placed EPS file includes a clipping path
in InDesign. However, deselecting this option may result in a different bounding box size.
Proxy Generation This creates a low-resolution bitmap representation of an image when drawing the file to the screen.
The following settings control how the proxy will be generated:
• Use TIFF Or PICT Preview Some EPS images contain an embedded preview. Select this option to generate the proxy
image of the existing preview. If a preview does not exist, the proxy will be generated by rasterizing the EPS to an
offscreen bitmap.
• Rasterize The PostScript Select this option to ignore the embedded preview. This option is typically slower but
provides the highest-quality results.
Note: When you import more than one single file into the same document, all instances share the proxy setting of the first
instance of the imported file.
Bitmap import options
You can apply color-management options to individual imported graphics when using color-management tools with
a document. You can also import a clipping path or an alpha channel saved with an image created in Photoshop. Doing
so lets you directly select an image and modify its path without changing the graphics frame.
When you place a PSD, TIFF, GIF, JPEG, or BMP file and select Show Import Options in the Place dialog box, you’ll
see a dialog box containing these options:
Apply Photoshop Clipping Path If this option isn’t available, the image wasn’t saved with a clipping path, or the file
format doesn’t support clipping paths. If the bitmap image doesn’t have a clipping path, you can create one in
InDesign.
Alpha channel Select an alpha channel to import the area of the image saved as an alpha channel in Photoshop.
InDesign uses the alpha channel to create a transparent mask on the image. This option is available only for images
that contain at least one alpha channel.
