perClass Mira 5.3 Documentation

Set the wavelength value of a band to resample to.

int miraacq_SetResamplingWavelength(makernel* pma, int band, double wavelength);

Parameters:

• pma: A pointer to the acquisition kernel returned by miraacq_Init.
• band: The band to set the wavelength to, must be less than the number set with miraacq_SetResamplingWavelengthCount.
• wavelength: The wavelength value in nanometers.

Return value:

MIRA_OK (0) or an error code.

Description:

miraacq_SetResamplingWavelength will set the wavelength of a specific band, the wavelengths need to be between the camera wavelength range (miraacq_GetFrameWavelength). Resampling requires that the camera is able to retrieve wavelengths (miraacq_CanReturnWavelengths).

Example:

Note the MIRAACQ_CHECK macro, which will check if the return value was MIRA_OK (0) or an error code. In case of an error code, it will jump to a label called Error.

1. int bands = ((1000 - 400) / 2) + 1; // + 1 is used to keep the final (1000 nm) band
2. MIRAACQ_CHECK(miraacq_SetResamplingWavelengthCount(pma, bands));
3. for (int i = 0; i < bands; i++) {
4.     MIRAACQ_CHECK(miraacq_SetResamplingWavelength(pma, i, 400 + (2 * i)));
5. }
6. MIRAACQ_CHECK(miraacq_SetResampling(pma, 1));
