Here are computer-related terms that we use in this documentation:

Term	Meaning

Hover	Move the mouse so that the pointer is over an object without clicking
Roll	If you have a thumb wheel on your mouse, roll it forwards or backwards (not moving the mouse itself)

Here are some industry terms that you should know:

Term

Meaning

Trim

The size of a canvas as it will be cut for presentation.

A typical business card has a trim size of 3.5x2 inches; a 5x7 print has a trim area of 5 by 7 inches.

Bleed

An optional extra space around the outside of a canvas; used to 'overprint', so that when the print is cut to the trim area, colors go cleanly to the edge of the cut print.

The bleed size can be set to any size you like.

This feature is available in FotoFusion ENHANCED and EXTREME only.

Safe

The region within the canvas that is sure to be visible when the print is mounted.

A 5x7 print mounted in a photo album may be overlapped by 1/4" on each side by the album's frame; this would produce a print with a safe area measuring 4.5x6.5".

The safe size can be set to any size you like.

This feature is available in FotoFusion ENHANCED only.

Crop Marks

Lines drawn on final output to indicate where the print should be cut to produce the desired trim size.

Gamma

An aspect of the color information for an image that can be controlled to produce more or less detail in the midrange of an image without affecting the black or white levels.

Alpha

The opacity of an image.

Alpha = 1 means the image is completely opaque;

Alpha = 0 means the image is completely transparent.

Aspect Ratio

The overall shape of an object expressed as a ratio of the width to the height without taking units into account; a square has an aspect ratio of 1:1 whether it is a foot or an inch on a side.

DPI

"Dots Per Inch" - a printing term describing the resolution of an image. More accurately it should be called "Pixels per inch". It measures the number of pixels that fit within an inch for an output device; for example a typical printer outputs at 300 DPI, while a typical computer monitor displays at 96 DPI.

To FotoFusion, DPI is really just a measure of the size of final output. If you create a 10x10 collage and go to the output tab, you can do this:

•	Set the DPI to 300 and get a 3000x3000 image

•	Set the output resolution to 5000x5000 and have the DPI field update to 500.

JPG compression ratio

A number from 0 to 100 indicating the quality of image desired when saving to the JPEG (or '.jpg') format. As the quality increases, the file size grows - you need to find a balancing point between acceptable image quality and the size of the image in an email or web page.

Copy

A standard computer technique for precisely duplicating information.

1.	Select the object (e.g. highlight text with the mouse)

2.	Press Ctrl-C This will copy the selected information to a 'clipboard' for subsequent pasting.

In FotoFusion, you cannot use Ctrl-C to duplicate images. The shortcut is Ctrl-D (duplicate)

Parameter

A value that can be edited, such as the blurriness of a shadow or the color of a frame border. Typically you set parameter values using an editor.

Paste

A standard computer technique for precisely duplicating information.

1.	Select and copy an object (e.g. text) to the clipboard

2.	Place the cursor where you want a copy of the object to appear

3.	Press Ctrl-V

This will paste the selected information from the 'clipboard' to the location specified in step 2.

In FotoFusion, you cannot use Ctrl-C to duplicate images. The shortcut is Ctrl-D (duplicate).
