factfile3.12 Optimising and Exporting

 

File size is always an issue when designing web graphics. A navigation bar can be made up of several individual smaller images, and so each one needs to be as small as possible or they will add up to the equivalent of a large file. When optimising a navigation bar for the web there needs to be a balance between the image quality and file size. A very low quality graphic will download very quickly but will not look very good. A high quality, full colour button will look great but take longer to download. Using fewer colours in your original design can help to optimise your navigation bar.

draw plus optimiser

DrawPlus and PhotoPlus let you save work files in their own proprietary file format. This allows you to make edits and changes to the files in the future, preserving layers and vector objects. When producing graphics for use on your web pages, you will also need to export your files as either GIF or JPG file formats (or SWF for Flash navigation bars)

Both DrawPlus and PhotoPlus have a useful feature in the form of an Export Optimiser, which will allow you cut file size by editing dimensions, the number of colours and, most significantly, resolution. This will enable you to achieve faster download times for site visitors and, depending on your examining board for your projects, higher grades.

The Export Optimiser also enables you to preview revised file sizes, download times and picture quality before hitting the Export button. For more on image optimisation, see section 2.
