Imaging Options

Print this Topic Previous pageReturn to chapter overviewNext page

The Imaging Options pane is used for configuring RelayFax's handling of fax images. You can designate whether or not images will be stored after they have been sent, whether to use enhanced resolution when creating them, the image format that will be used when emailing faxes to your users, and several other options.

Fax Image Options

Remove fax images from disk after they are sent

Enable this control if you want RelayFax to delete fax image files from disk after they have been delivered to their final destination. Since fax image files can be somewhat large, this feature can be used to conserve storage space if that is of concern to you.

Several features require the fax image to be present on disk (for example: viewing the image from the Fax Window on the main interface). Consequently, if you are removing images from the disk not all features will be available.

Create fax images in enhanced resolution

Use this switch if you wish to send high-resolution images when a document is faxed. Selecting this switch provides superior fax image quality but consumes a bit more disk space and transmission time.

Fax Image Manipulation

Incoming faxes should be sent to users as...

This is the image format that will be used when sending incoming faxes to your users in the form of email attachments.

a single multi-page TIF image (image/tif, default)

This is the default setting. When selected it will cause a single multi-page Tag Image File Format (TIFF) image of the incoming fax to be attached to the message. This file will have the TIF extension.

multiple TIF images (image/tif, 1 image per faxed page)

This option will cause a separate TIFF image to be attached for every page that the fax contained. This can be useful since some TIFF viewers do not support multiple pages.

multiple JPG images (image/jpg, 1 image per faxed page)

Causes one JPEG image to be attached per faxed page.

multiple GIF images (image/gif, 1 image per faxed page)

When this option is selected, RelayFax will attach a single Graphic Interchange Format (GIF) image for each page that the fax contained.

multiple BMP images (image/bmp, 1 image per faxed page)

Multiple Bitmap (BMP) images will be attached when this option is chosen.

multiple PNG images (image/png, 1 image per faxed page)

Multiple Portable Network Graphic (PNG) images will be attached when this option is chosen.

a single PDF document (image/pdf)

This option sends incoming faxes to users as a single multi-page Portable Document Format (PDF) file.

RelayFax also supports PDF encryption. To create encrypted PDF files, choose this imaging option and add the following to your RelayFax.ini file:




(Recommended) An owner password gives full access to the document. No owner password means that anyone can change the permissions.


Designating a user password means that it will be required to open the document.


"-64" disallows printing, editing, copying, and so on. "-44" permits printing and copying but disallows modifying the contents and annotations. "-4" allows all. For more on encryption and permissions, see the Adobe PDF Specification at

The following options will not be available when you choose the single multi-page TIF image option above.

Always create fax images with this extension [xx] (blank for default)

If you want the file attachments to have an extension other than the given format's default setting, specify that extension here.

Scale image to [xx] percent actual size (10-200%)

Specify a percentage in this option if you want the attached image file to be scaled to a different size than the original fax image. You may specify any value from 10% to 200%.
