<font face="Arial, Verdana" size="2">OpenLP will stretch images automatically, but it always retains the correct image aspect ratio - it will not make the image go out-of-proportion. Examples: If you supply an image of size 800 x 600, and your projector screen is 1024x768, OpenLP will automatically stretch your image to 1024x768. However, if you supply an image of size 800 x 400, and your projector screen is 1024x768, OpenLP will only stretch that image to 1024x512 – this second stretched image will then not fill your screen fully as it is only 512 pixels high and you will have a little gap or margin at the top and bottom. OpenLP allows you to define the colour of this margin within each theme.</font>

<font face="Arial, Verdana" size="2">There is a learning-curve with themes (there’s a learning curve with the whole program) but once you get the idea it becomes easier. Here are two tips for themes: (a) For background images, always choose images with the correct aspect ratio for your projector and (b) There is no need to build a new theme from scratch each time – whenever you want a new theme, start with one that already works well for you, make a copy of that, then rename your copy, then make your required changes. This is so much quicker than starting a new theme from scratch.</font>

<font face="Arial, Verdana" size="2">Once you have a good set of themes, to change text on the fly, you just change your theme.</font>

<font face="Arial, Verdana" size="2">OpenLP has many options and facilities but that does give the program quite a steep learning curve. Once you get up the curve it’s good. The program has always been rock solid and reliable on my computers – I have never known OpenLP to freeze or let me down during a service.</font>
