IN_ChangeDetailLevel

All Editions $image\bltlrgsq_shg.gif$ Related Functions $image\bltlrgsq_shg.gif$ Example

The IN_ChangeDetailLevel function sets how much detail is displayed in a JPEG 2000 or MrSID file while it is open. These raster formats, which can contain a large amount of information, are loaded in Imagenation at a lower resolution, providing a fast overview of the entire image. This function enables faster load times of very large JPEG 2000 and MrSID files, or to display more details when needed.

Remarks

Currently only available for JPEG 2000 and MrSID formats.

These are display changes only. They do not change the actual file data.

You can also zoom in on a portion of the image and use this function to increase or decrease the detail level of that portion only.

Increasing the detail level to maximum can sometimes take several minutes, depending on file size and on the current view level.

Release information

Added to Imagenation for Windows in Release 7.2.

Not yet available in Imagenation for UNIX.
