This section contains data which is collected during image loading, rather than obtained from image's header or metadata. Only image loading methods, such as LoadPage Method or LoadPageFromFile Method generate this section. Header reading methods, such as GetPageInfo Method, do not generate it.
For some cameras ImageGear uses predefined values for BlackLevel, so they are not calculated from pixel data. In this case, ImageGear also places BlackLevel tag to Statistics section, rather than in Common section, for uniformity reasons.
The following tags can be present in the Statistics section:
| Name | ID | Description |
|---|---|---|
| BlackLevelRepeatDim | IGMDTAG_ID_DCRAW_BLACKLEVELREPEATDIM | This tag specifies repeat pattern size for the "BlackLevel" tag. |
| BlackLevel | IGMDTAG_ID_DCRAW_BLACKLEVEL | This tag specifies the zero light (a.k.a. thermal black or black current) encoding level. It is calculated during image loading by averaging pixel values in the masked areas of the image. |
