BitmapV4Header (108 bytes): A BitmapV4Header Object, which defines properties of the DIB Object (section 2.2.2.9).

When it is part of a BitmapV5Header, the ColorSpaceType field of a BitmapV4Header can be a logical color space value in the LogicalColorSpaceV5 Enumeration (section 2.1.1.15).

Intent (4 bytes): A 32-bit unsigned integer that defines the rendering intent for the DIB. This MUST be a value defined in the GamutMappingIntent Enumeration (section 2.1.1.11).

ProfileData (4 bytes): A 32-bit unsigned integer that defines the offset, in bytes, from the beginning of this structure to the start of the color profile data.

If the color profile is embedded in the DIB, ProfileData is the offset to the actual color profile; if the color profile is linked, ProfileData is the offset to the null-terminated file name of the color profile. This MUST NOT be a Unicode string, but MUST be composed exclusively of characters from the Windows character set (code page 1252).

If the ColorSpaceType field in the BitmapV4Header does not specify LCS_PROFILE_LINKED or LCS_PROFILE_EMBEDDED, the color profile data SHOULD be ignored.

ProfileSize (4 bytes): A 32-bit unsigned integer that defines the size, in bytes, of embedded color profile data.

Reserved (4 bytes): A 32-bit unsigned integer that is undefined and SHOULD be ignored.
