virtual void zxhMetricMultiImageBase::SetMultiMetricBase

(

)

[protected, pure virtual]

this function is to remind of setting m_pMImgMetricBase and m_pMImgMetricType in derived class {m_pMImgMetricBase=this; m_pMimgMetricType=new Metric;}

Implemented in zxhMetricMIFFD2MultiImage, and zxhMetricMIMultiImage.

bool zxhMetricMultiImageBase::UpdateOtherImageMetric

(

bool

bupdate

)

[protected, virtual]

1) check whether need to update 2) SetMultiMetricBase, clone metric (including sampling, mask, transform, diff... info) save all test image into the test space, with spacing to physical sample interval 3) set test and ref image ; update m_bNeedToUpdateOtherImageMetric return whether updated

Reimplemented in zxhMetricMIFFD2MultiImage.
