Hi there,

I'm looking for compression options on saving MultipassBitmap as EXR file. As ZIP, PIZ, ZIPS, etc... How can we set it?

Thanks,
A.

Hi Ahmet,

The BaseBitmap::Save() function has a data parameter, where you can pass additional configuration options.
For EXR you pass a BaseContainer containing another BaseContainer at ID 0 with the actual settings.

The second BaseContainer then contains the following settings:

ID 0: Int32 value, the compression type (one from the list below)
0 = NO_COMPRESSION
1 = RLE_COMPRESSION
2 = ZIPS_COMPRESSION
3 = ZIP_COMPRESSION
4 = PIZ_COMPRESSION
5 = PXR24_COMPRESSION
6 = B44_COMPRESSION
7 = B44A_COMPRESSION

ID 1: Boolean value, clamp to 16-Bit float

There's also another thread showing about Setting the format options of an OpenEXR in the render settings.

Please note that setting these IDs on your own could break at some point in time in case their support in OpenEXR is removed or extended (e.g. the first versions of the EXR lib only had a fraction of these options).

Best regards,
