Opening and importing images

Opening and importing images

You can open and import images in various file formats. The available formats appear in the File Browser the Open dialog box the Open As dialog box ( Windows) or the Import submenu (See About file formats on section 453

Note: Photoshop and ImageReady use plug-in modules to open and import many file formats If a file format does not appear in the Open dialog box or in the File > Import submenu you may need to install the format s plug-in module (See Using plug-in modules on section 58

Opening files

You can open files using the Open command and Open Recent command In Photoshop, you can also open files using the File Browser For more information see "Using the File Browser (Photoshop) on section 78

There may be instances when Photoshop cannot determine the correct format for a file. For example transferring a file between Mac OS and Windows can cause the format to be mislabeled In such cases you must specify the correct format in which to open the file. To open a file using the Open command:

Choose File > Open.

Select the name of the file you want to open If the file does not appear select the option for showing all files from the Files of Type ( Windows) or Show (Mac OS) pop-up menu.

(Mac OS) Click Show Preview to preview the selected file. This option requires the Apple

QuickTime extension.

Note: Previews display faster if they are saved with the file In Photoshop select Always Save for Image Previews in the Saving Files preferences to always save a preview select Ask When Saving to save previews on a file-per-file basis.

Click Open In some cases a dialog box appears letting you set format-specific options.

Opening and importing PDF files

Portable Document Format (PDF) is a versatile file format that can represent both vector and bitmap data and can contain electronic document search and navigation features. PDF is the primary format for Adobe Illustrator and Adobe Acrobat For more information on the PDF format see "PDF on section 456

Some PDF files contain a single image Other PDF files (called Generic PDF files) may contain multiple pages and images. When you open a Generic PDF file you can choose which page to open and specify rasterization options If you want to open an image

(versus a page) from a PDF file you can use the File > Import > PDF Image command. You can also bring PDF data into Photoshop or ImageReady using the Place command, the Paste command and the drag-and-drop feature (See "Placing files on section 80

"Using drag and drop to copy between applications on section 170 and "Using the

Clipboard to copy between applications on section 171

To open a PDF file:

Choose File > Open.

Select the name of the file and click Open. You can change which types of files show by selecting an option from the Files of Type ( Windows) or Show (Mac OS) pop-up menu.

If you are opening a Generic PDF file do the following:

If the file contains multiple pages select the page you want to open.

Indicate the desired dimensions resolution and mode If the file has an embedded ICC profile and Preserve Embedded Profiles is selected for Color Management Policies in the Color Settings dialog box you can choose the profile from the mode pop-up menu.

Select Constrain Proportions to maintain the same height-to-width ratio.

Select Anti-aliased to minimize the jagged appearance of the artwork s edges as it is rasterized.

To import images from a PDF file:

Choose File > Import > PDF Image select the file you want to import images from, and click Open.

Select the image you want to open:

To open a specific image select it and click OK. You can use the arrows to scroll through the images or click Go to Image to enter an image number.

To open each image as a separate file click Import All Images.

Press Esc to cancel the import operation before all images are imported.

To create a new Photoshop file for each page of a multiple-page PDF file

(Photoshop):

Choose File > Automate > Multi-Page PDF to PSD.

Under Source PDF click the Choose button and select the file you want to import images from.

Under Page Range specify a range of pages to import.

Under Output Options specify a resolution choose a color mode and set the Anti-alias option for rasterizing each page of the PDF file ( To blend edge pixels during rasterization, select the Anti-alias option. To produce a hard-edged transition between edge pixels during rasterization deselect the Anti-alias option.)

Under Destination enter a base name for the generated files ( When Photoshop creates the new files the base name is appended with a number that corresponds to the page number of the PDF file.) Then click the Choose button and select the location where you want to save the generated files.

Opening PostScript artwork

Encapsulated PostScript (EPS) can represent both vector and bitmap data and is supported by virtually all graphic illustration and page-layout programs Adobe applica- tions that produce PostScript artwork include Adobe Illustrator Adobe Dimensions and Adobe Streamline. When you open an EPS file containing vector art it is rasterized-the mathematically defined lines and curves of the vector artwork are converted into the pixels or bits of a bitmap image.

You can also bring PostScript artwork into Photoshop or ImageReady using the Place command the Paste command and the drag-and-drop feature (See "Placing files on section 80 "Using drag and drop to copy between applications" on section 170 and "Using the Clipboard to copy between applications on section 171

To open an EPS file:

Choose File > Open.

Select the file you want to open and click Open.

Indicate the desired dimensions resolution and mode. To maintain the same height-to- width ratio select Constrain Proportions.

Select Anti-aliased to minimize the jagged appearance of the artwork s edges as it is rasterized.

Turning off anti-aliasing for PDF and EPS files (ImageReady)

The Anti-alias PostScript option removes jagged edges from a pasted or placed selection by making a subtle transition between the edges of the selection and its surrounding pixels. Turning off this option produces a hard-edged transition between pixels-and therefore the appearance of jagged edges-when vector artwork is rasterized.

Note: In Photoshop you can deselect the Anti-alias option when you open or place a PDF

or EPS file.

To turn off the Anti-alias PostScript option:

Do one of the following:

In Windows or Mac OS 9.x choose Edit > Preferences > General.

In Mac OS X choose ImageReady > Preferences > General.

Deselect Anti-alias PostScript Clearing this option can decrease the time it takes to import the file.

Opening Photo CD files

You can open Kodak Photo CD (PCD) files including high-resolution files from Pro Photo

CD discs.

Note: You cannot save files in PCD format from Photoshop or ImageReady.

To open a Photo CD file:

Choose File > Open.

Select the PCD file you want to open and click Open If the file does not appear select the option for showing all files from the Files of Type ( Windows) or Show (Mac OS) menu.

Select options for the source image:

Pixel Size to specify the pixel dimensions of the image Keep in mind that the on-screen size of the opened image depends on both the pixel size and resolution you choose.

(See About image size and resolution on section 62

Profile to specify a device profile for color management (See About color management on section 102

Select options for the destination image:

Resolution to specify the resolution of the opened image.

Color Space to specify a color profile for the opened image (See About color management on section 102

Landscape or Portrait to specify the orientation of the opened image.

Opening Raw files (Photoshop)

The Raw format is designed to accommodate images saved in undocumented formats, such as those created by scientific applications Compressed files such as PICT and GIF, cannot be opened using this format.

To open a file using the Raw format:

Choose File > Open or File > Open As ( Windows).

Choose Raw from the file format list and click Open.

For Width and Height enter values for the dimensions of the file.

To reverse the order of the width and height click Swap.

Enter the number of channels.

Select Interleaved if the file was saved with an interlaced data option.

Select a color depth and if necessary a byte order.

For Header enter a value.

If you are missing the dimensions or header value you can have Photoshop estimate the parameters Either enter the correct height and width values to estimate the header size or enter the correct header size to estimate the height and width and then click Guess.

To have Photoshop retain the header when you save the file select Retain When

Saving.

Importing anti-aliased PICT files (Mac OS)

Choose File > Import > Anti-aliased PICT to import object-oriented PICT files (such as those created with MacDraw and Canvas) as smooth-edged or anti-aliased images. Because the entire PICT file must be held in memory for this module to operate you may not be able to use the module with large PICT files.

The Anti-aliased PICT dialog box indicates the current file size and dimensions. To change the image dimensions enter new values for Width and Height. The file size is then updated. To maintain image proportions select Constrain Proportions.

You can choose Grayscale or RGB color mode for an anti-aliased PICT file.

Importing PICT resources (Mac OS)

The PICT Resource module lets you read PICT resources from a file-for example from another application. To open a PICT resource choose File > Import > PICT Resource.

To preview a resource click Preview Click the arrow buttons to step forward and backward through the resources Note that the number displayed for Resource refers to the resource s position in ascending order in the resource fork and not to the resource s identi- fication number.

Note: In Photoshop you can also open a file in the PICT Resource file format by choosing File > Open choosing All Documents from the Show pop-up menu selecting the file you want to open choosing PICT Resource from the Format pop-up menu and clicking Open. However the Open command automatically opens the first resource in the file and does not display any other PICT resources in the file.
