The QTVR settings dialog box appears when you press the QTVR settings... button on the Save Image As dialog box. It lets you control attributes of the QTVR image file. For more information see “QTVR image file format” in this chapter.
Image
quality
The text field and its associated slider control the tradeoff
between JPEG image file size and image quality. Lower quality settings tend to
reduce file sizes.
NOTE: Extremely high quality settings may produce large files with minimal improvements in image quality. In general, there may be diminishing returns for values higher than 75%.
Compression
method
The QuickTime format provides a variety of image compression
formats with different characteristics. The Panorama Factory supports the
following subset of the QuickTime image formats:
JPEG
Sorenson
Cinepak
PNG
Viewer
size
Sets the dimensions of the panoramic viewer object on the web
page. This is independent of the size of the image file itself. If you want
to permit some degree of zoom-in without loss of resolution, the image file
should be larger than the viewer.
Automatic
rotation
Controls automatic rotation of the image. If you select
automatic rotation, the rotation begins when the image loads and continues
until the user touches the view with the mouse. Please note that automatic
rotation of QTVR panoramas is performed by Javascript in the web page. The
person viewing the web page must enable Javascript for automatic rotation to
function.
None — No automatic rotation.
Left — Rotate as though the person viewing the image was looking toward the left side of the image.
Right — Rotate as though the person viewing the image was looking toward the right side of the image.
Speed — Controls the speed of rotation in revolutions per minute.
Color
management
Controls color management for the QTVR images created by The
Panorama Factory. QTVR format does not support embedded color profiles. These
options contol whether a color space conversion is performed when you save QTVR
files. We recommend converting to the sRGB profile when saving QTVR files.
Do not convert when saving — Select this radio button to save the image without color space conversion.
Convert to specified color profile when saving — Select this radio button to convert the image to a specific color profile.
Profile — Controls the color profile to use.
