8.2.4. Saving Changes
For changes to be made a permanent part of the PDF document, the file must be saved.
If the user attempts to close a document after having made changes, Acrobat will
automatically prompt the user as to whether they want to save the document or not.
Saving changes in this method certainly makes them a part of the document. However,
the standard “Save” leaves the document in a non-optimized state. For this reason it is
recommended that the user perform a “Save As” from the Acrobat file menu before
closing the document. This has the effect of “cleaning up” the document and making the
smallest possible file.
8.2.5. General Notes
1. Regardless of the original PDF format, when a document is saved in Acrobat 5.x it
will be saved as PDF 1.4 format.
2. Cut, copy and paste work only within Acrobat. Images cannot be copied to the
clipboard for use in other applications. To use an image outside of Acrobat, or in a
different PDF document, choose “Extract Image...” from the Images menu. Copy and
paste of whole images between documents can be performed using the standard
Acrobat Object Select tool.
3. When an image is copied then pasted, the copy will be placed down and to the right
by approximately 10 pixels. This is so that the user can readily see the duplicate
image. When pasting images to a different page in the same document the pasted
image will appear at the same location as the original image relative to the lower left
corner of its page plus the offset described above.
4. The bits in a CMYK Photoshop JPEG file are inverted from those in a “standard” CMYK
JPEG file. Photoshop and most high-end page layout applications understand the
Photoshop JPEG format and will display the image correctly, while they will display a
standard JPEG image in inverted mode. Acrobat, on the other hand, always invert
the bits when a CMYK JPEG image is inserted into a PDF document using either the
“New Image...” or Replace Image...” functions described later. If you get unexpected
“negative” images, use the other JPEG format. This note only applies to CMYK
images. In other color spaces Photoshop and “standard” JPEG files are identical.
5. Extracted images are resized to the system resolution (on Windows this is 96 dpi,
on Macintosh this is 72 dpi). The extracted image contains all
of the image data,
but if these images are placed/opened in a page layout or an external image editing
application the size will appear larger than it was in the PDF by the ratio of the
original resolution divided by the system resolution. Simply resize the image
dimensions to whatever you like and the resolution will increase or decrease
accordingly.
