Some User Preferences can be set with this panel. These settings are stored in the registry.



Internal rendering DPI
The editor caches drawn shapes very often. This ensures that it can smoothly scroll and zoom on the document. This setting controls with which resolution the editor creates the cache images.

DPI stands for "Dots Per Inch". A high setting means you can zoom in very far before you will notice a blurry pixelated effect. Setting this to smaller values will mean that you notice the pixelation much earliear.

The default setting is 150. This is quite reasonable for most types of use. Set it to 300 or higher if you want a very high-quality image, even when zoomed in. When you want fast browsing through your document, try a setting of as low as 50.

Important: This setting does not influence the final quality of the document at all. Every shape is either stored in vector format (independent of resolution) or in the original format with which graphics were added.

Print quality

·	Low print quality (150 DPI)

·	Medium print quality (300 DPI)

·	High print quality (600 DPI)

·	Device print quality (best possible DPI)

Here you choose which quality to use for printing. Most prints look quite acceptable on the lowest setting of 150 DPI. Printing will also be very fast at this setting. However, for higher quality prints and photographs, try using 300 DPI or higher. Warning: the 600 DPI and best possible DPI options may be very slow! In some cases, the printer driver cannot even handle such vast amounts of data.

Resample method
When the editor zooms in, the resulting image is often taken from the cached version. In order to do so, it needs to resize the cached image to the current zoom factor. The resample method used for this process is chosen here.

·	Fast, low quality The lowest setting.. You will notice a very grainy effect.

·	Medium Reasonable on slow and medium speed computers

·	High This is the default. Use this unless the response is sluggish, in that case you would better use Medium.

·	Superhigh (slow) This is the best possible quality, but comes with a price: it is slow.

Select multiple shapes by...
This defines how selecting of multiple shapes works by mouse:

·	Using [Ctrl] + mouse drag You must first press [Ctrl] before you can drag a rectangle over or around the shapes you want to select. This method has as advantage that you can start the rectangle anywhere on a shape, and the [Ctrl] avoids that you select it already.

·	Starting mouse drag from empty area Now you do not have to press [Ctrl], but you must be sure that the mouse pointer is in an empty area when you start dragging the selection rectangle.

Performance Control

·	Favour memory over speed (safest)

·	Favour speed over memory (only w. much mem!)

If you own a very fast computer with a lot of memory, then it may be beneficial to change this setting to the second option. In this case, whenever you change a page, the caches are preserved and browsing through the pages becomes much more responsive.

However, if your document contains a lot of images and your computer has no more than 512 Mb of memory, it is better to not allow all memory to fill up and it is advisory to use the first option in that case.
