Use this dialog box to control how you compress your pictures.
- GIF files cannot be significantly compressed further.
- An object inserted by using the Object command on the Insert menu cannot be compressed, because it is inserted as an object and not as a picture.
Current combined image size Displays the current combined size of all pictures in the publication.
Estimated combined image size after compression Displays the estimated combined size of all pictures in the publication after compression. (This value changes depending on other options that you select.)
Delete cropped areas of pictures Select this check box to delete the pixel information that is normally stored for cropped areas of pictures. (The information that is associated with cropped areas is neither visible nor used.)
Remove OLE data Select this check box to remove the 24-bit uncompressed bitmap that is part of a picture's OLE stream. The small viewable image that is part of the OLE stream is deleted, but the picture itself appears the same. (After you remove the OLE data from a picture, you are no longer able to open that picture by using the program originally used to create the picture.)
Resample pictures Select this check box to make a resized picture smaller by deleting the residual data from the picture's original size. (If a picture is resampled, and then stretched larger than the size rate at which it was resampled, the picture quality is reduced.)
Convert to JPEG where appropriate Select this check box to convert the picture to a JPEG file.
- Depending on the nature of the picture — such as whether it is a photo, how much noise or spiking is in the picture's histogram, and so on — the level of compression varies. The compression level of PNG pictures cannot be modified.
- Pictures that are 100 KB or less are not compressed.
