specified a font size, the size of the text does not change but the background scales to the values you type
in. This is useful if you want to create several headings, all the same height and width.
Color depth:
the more colors, the larger the file size. For animations where each image appears for only a short period
you may find 256 colors gives satisfactory results.
Dithering
(dimmed except for 256-colors). None creates the smallest files but you may see bands of colors instead
of smooth color graduations.
Transparent
(dimmed for High-color): select this for a transparent background to the animation. Deselect for a solid
background.
Lossless and quality (dimmed except for true-color): quality values below 100% give smaller files but
at a lower quality. Lossless
is equivalent to 100% quality. You may need to experiment to get the best trade-off between quality and
file size.
Export options for Flash vector format (SWF) files
These options apply to both static and animated SWF files. More information on creating Flash files
.
Note that Flash vector format does not support some Xara 3D Maker features (such as shadows and
textures). You can use Xara 3D Maker features not supported in vector format except shadows but
these get exported as bitmaps within the Flash file and can make the file much larger. If you intend to
output in SWF format, we suggest using the display as Flash option on the View menu.
Current window size lets you export just the area surrounding the text (Crop on) or the entire window
area (Crop
off.)
User defined lets you specify the dimensions of the bitmap. With Fit to width
(on the text toolbar) selected, the text and the background scales to suit the values you type in. If you
specified a font size, the size of the text does not change but the background scales to the values you type
in. This is useful if you want to create several headings, all the same height and width.
Quality:
the higher the quality, the larger the file. You may need to experiment to get the best trade-off between
quality and file size.
General info on AVI videos
The AVI format (Audio Video Interleaved) isn't actually a proper video format! It's rather a so-called
container where very general conventions such as audio and video data can be specified and sent to a
program. The exact memory format of the files is specified via the codec (coder/dec
oder). A codec compresses audio/video files into its own private format with which only that codec can
work and decodes the files again on playback.
This means that an AVI file created on your computer can only
be loaded/played on computer B if this computer has the same codec installed.
Many codecs (for example, Intel Indeo
 video) have now become standard components of the Windows installation. Others, such as the
popular DivX codec, are not. If you create an AVI file with such a codec and you wish to use it on other
computers, install the corresponding codec on them as well.
On older video editing cards certain codecs that function only with the hardware of the corresponding
cards can be problematic. This type of AVI can only
be used on the computer on which they were created. Avoid using this type of codec when possible.
