Portable Network Graphics (.png) import options
When you place a PNG image and select Show Import Options in the Place dialog box, you’ll see a dialog box with
three sections of import settings. Two sections contain the same options available for other bitmap image formats. The
other section, PNG Settings, contains the following settings:
Use Transparency Information This option is enabled by default when a PNG graphic includes transparency. If an
imported PNG file contains transparency, the graphic interacts only where the background is transparent.
White Background If a PNG graphic does not contain a file-defined background color, this option will be selected by
default. However, it is only enabled if Use Transparency Information is activated. If this option is selected, white is
used as the background color when applying transparency information.
File Defined Background Color If a PNG graphic was saved with a non-white background color, and Use
Transparency Information is selected, this option is selected by default. If you don’t want to use the default background
color, click White Background to import the graphic with a white background, or deselect Use Transparency
Information to import the graphic without any transparency (displaying areas of the graphic that are currently
transparent). Some image-editing programs can’t specify a non-white background color for PNG graphics.
Apply Gamma Correction Select this option to adjust the gamma (midtone) values of a PNG graphic as you place it.
This option lets you match image gamma to the gamma of the device you will use to print or display the graphic (such
as a low-resolution or non-PostScript printer or computer monitor). Deselect this option to place the image without
applying any gamma correction. By default, this option is selected if the PNG graphic was saved with a gamma value.
Gamma Value This option, available only if Apply Gamma Correction is selected, displays the gamma value that was
saved with the graphic. To change the value, type a positive number from 0.01 to 3.0.
When PNG files are imported, the settings in the Image Import Options dialog box are always based on the selected
file, not on the default or last-used settings.
Acrobat (.pdf) and Illustrator (.ai) import options
The layout, graphics, and typography in a placed PDF are preserved. As with other placed graphics, you cannot edit a
placed PDF page within InDesign. You can control the visibility of layers in a layered PDF. You can also place more
than one page of a multipage PDF.
When you place a PDF that was saved with passwords, you’ll be prompted to enter the required passwords. If the PDF
file was saved with usage restrictions (for example, no editing or printing), but no passwords, you can place the file.
When you place a PDF (or a file saved with Illustrator 9.0 or later) and select Show Import Options in the Place dialog
box, you’ll see a dialog box containing the following options:
Show Preview Preview a page in the PDF before you place it. If you’re placing a page from a PDF that contains multiple
pages, click the arrows, or type a page number under the preview image to preview a specific page.
Pages Specify the pages you want to place: the page displayed in the preview, all pages, or a range of pages. For
Illustrator files, you can specify which artboard to place.
If you specify multiple pages, hold down Alt (Windows) or Option (Mac OS) while placing the file to place them all at
the same time, overlapping each other.
Crop To Specify how much of the PDF page to place:
• Bounding Box Places the PDF page’s bounding box, or the minimum area that encloses the objects on the page,
including page marks. The Bounding Box (Visible Layers Only) option uses the bounding box only of the visible layers
of the PDF file. The Bounding Box (All Layers) option places the bounding box of the entire layer area of the PDF file,
even if layers are hidden.
