File Size and Number of Colors
When you prepare graphics for TestGen, the size of each graphic file must be less than one
megabyte (1 MB = 1000 bytes). If the image is large and the file size is larger than 1 MB, you can
break the image into two or more parts to insert into the question in a side-by-side or stacked
configuration.
Reducing the number of colors in your graphics to 256 or grayscale usually preserves more than
enough detail, while making the file size smaller and reducing the time it takes to download
images for online tests. Two-color images (black and white) usually work for simple line art, while
16 or 256 colors usually work well for more detailed images. If possible, process the images to
make them web-ready before importing into TestGen. Images using 24-bit color may be too large
to import.
Setting Graphics Preferences
During testbank editing, you can insert graphics and function plots as either text characters or
transparent objects. Indicate which setting you prefer by selecting "Preferences > Application"
from the Tools menu and clicking the Graphics Position tab.
Graphics and function plots inserted as text characters become part of the line of text and move
along with the text if characters are inserted or deleted or if the text wraps to the next line. They
affect the line spacing by aligning the bottom of the graphic with the baseline of the line of text.
Graphics and function plots inserted as transparent graphics can be placed at a static location
and remain in the background so you can type over and around the image to place labels or other
information.
Positioning and Editing Transparent Graphics and Function Plots
When you insert a graphic or function plot as a transparent object, it is automatically placed in the
upper-left corner of the field where you inserted it, at coordinates (0,0).
Note: If the graphic or function plot is the only object in the edit field, you may see only the first
line of it because only one line of text is visible. Press the [Enter] or [Return] key several times to
add more lines to the field and display the rest of the graphic.
To reposition a transparent graphic, first select "Transparent Graphics" from the Tools menu. This
displays a list of the graphics and function plots used in the current field. Select an object in the
list, click the Position button, and enter new coordinates for the upper-left corner of the graphic.
Tip: The measurements are in pixels, so remember that an inch on-screen is approximately 96
pixels (Windows) or 72 pixels (Macintosh).
