  DWORD  dwLogotypeImageInfoChoice;
  DWORD  dwFileSize;
  DWORD  dwXSize;
  DWORD  dwYSize;
  DWORD  dwLogotypeImageResolutionChoice;

Members

dwLogotypeImageInfoChoice

Specifies the type of image. This can be one of the following values.

Value	Meaning
CERT_LOGOTYPE_GRAY_SCALE_IMAGE_INFO_CHOICE	The image is a grayscale image.
CERT_LOGOTYPE_COLOR_IMAGE_INFO_CHOICE	The image is a color image.

dwFileSize

The size, in octets, of the image.

dwXSize

The horizontal size, in pixels, of the image.

dwYSize

The vertical size, in pixels, of the image.

dwLogotypeImageResolutionChoice

Specifies the format of the image resolution. This can be one of the following values.

Value	Meaning
CERT_LOGOTYPE_NO_IMAGE_RESOLUTION_CHOICE	No image resolution information is provided.
CERT_LOGOTYPE_BITS_IMAGE_RESOLUTION_CHOICE	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.

DUMMYUNIONNAME

DUMMYUNIONNAME.dwNumBits

The resolution of the image, in bits per pixel. The member is only used if the dwLogotypeImageResolutionChoice contains CERT_LOGOTYPE_NO_IMAGE_RESOLUTION_CHOICE.

DUMMYUNIONNAME.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

The address of a null-terminated IA5 string that contains the RFC 3066 language identifier that specifies the language of the image. This member is optional and may be NULL.
