PhaseOne IIQ

Long name	PhaseOne Intelligent Image Quality (IIQ)
Short name	IIQ
File extension	.IIQ

Phase One's Intelligent Image Quality (IIQ) file format is a proprietary, compressed format for raw image data captured by Phase One cameras.

CATALYST software uses the Phase One Image SDK to decompress and convert compressed IIQ images. The Phase One Image SDK has the ability to decompress imagery to various output configurations, as specified in .ixp files. Configuration options include changing the bit depth and the number of channels. The default configuration is read from the file: $PCIHOME/etc/p1convert.ixp. You can override this by creating a new configuration file using Phase One software or by editing the file by hand, and placing the file in one of the following folders.

The resolution order for choosing the convert configuration file to use, when decompressing IIQ files, is as follows:

The {basename}.ixp file in the same folder as the IIQ file, where the IIQ file is: {basename}.iiq. Use this when you need a different configuration for each IIQ file.
The p1convert.ixp file in the same folder as the IIQ file. Use this when you have projects that need different configurations.
The p1convert.ixp file in the phase_one subfolder of the user data folder:
- Linux: $HOME/.pci_geomatics/phase_one/p1convert.ixp
- Windows: %APPDATA%\PCI Geomatics\phase_one\p1convert.ixp
Each user can override the system default configuration with this option.
The default config file: $PCIHOME/etc/p1convert.ixp

The first file found from the list is used, and the subsequent locations are not checked.

Note: Since IIQ files are compresssed, using them is very slow and consumes a lot of time and memory. It is recommended that you import the data to PIX files before doing any processing.
