The image resolution is provided in bits per pixel. The dwNumBits member contains the image resolution.

CERT_LOGOTYPE_TABLE_SIZE_IMAGE_RESOLUTION_CHOICE

The image resolution is provided in number of gray tones. The dwTableSize member contains the image resolution.

 

dwNumBits

dwTableSize

The resolution of the image, in number of gray tones. The member is only used if the dwLogotypeImageResolutionChoice contains CERT_LOGOTYPE_TABLE_SIZE_IMAGE_RESOLUTION_CHOICE.

pwszLanguage
