Remarks

Options include:

Value	Description
DontCare	No pixel format is specified for the image.
Undefined	The pixel format is undefined (for instance, if the Office Image container is empty).
Max	The maximum TdxOfficePixelFormat enumeration value.
Indexed
Gdi
Format16bppRgb555	The 16-bit color depth for High color RGB images. This format uses 15 bits to store the red, green, and blue color channel information. The remaining bit is ignored.
Format16bppRgb565	The 16-bit color depth for High color RGB images. This format uses 5, 6, and 5 bits to store the red, green, and blue color channel information, respectively.
Format24bppRgb	The 24-bit color depth for True color RGB images.
Format32bppRgb	The 32-bit color depth for True color RGB images. This format uses 24 bits to store the red, green, and blue color channel information. The remaining 8 bits are ignored.
Format1bppIndexed	The 1-bit color depth for color-mapped images. The color palette consists of only two colors.
Format4bppIndexed	The 4-bit color depth for color-mapped images.
Format8bppIndexed	The 8-bit color depth for color-mapped images. The color palette consists of 256 colors.
Alpha
Format16bppArgb1555	The 16-bit color depth for High color RGB images. This format is similar to Format16bppRgb555, but uses the last bit to store transparency information.
PAlpha
Format32bppPArgb
Extended	This value is not in use (it is, reserved).
Format16bppGrayScale	The 16-bit color depth for grayscale images (up to 65536 different colors).
Format48bppRgb
Format64bppPArgb
Canonical
Format32bppArgb	The 32-bit color depth for True color RGBA images.
Format64bppArgb	The 64-bit color depth for RGBA images. The format uses 16 bits to store each color channel.

The Office Image container’s PixelFormat property references the TdxOfficePixelFormat type.
