ippStsGammaRangeErr
Gamma correction parameters must be positive and must satisfy the range rules of the selected primitive. Nonpositive bounds make the transfer curve undefined or unusable for the operation.
Check this before investigating color conversion matrices. Gamma range errors are about the nonlinear correction domain, not about RGB-to-gray coefficients or channel order.
Check these details
- Lower and upper gamma range bounds.
- Whether UI values were converted from percentages or stops correctly.
- Whether per-channel gamma arrays contain zero or negative entries.
