Description
FillDescription is a procedure used to store descriptive
information about the raw image data in the resolution. FillDescription
provides metadata about the image, similar to the metadata in TIFF (Tagged
Image File Format). It provides information needed to process and render
images from their raw image data.
ADesc is the TRawImageDescription output parameter where the information is stored in the method. FillDescription calls the Init method in ADesc to reset the values in the class instance to their defaults.
FillDescription sets the value for the following properties in ADesc:
- Format
- ricfRGBA
- PaletteColorCount
- 0
- MaskBitsPerPixel
- 0
- Depth
- 32
- Width
- Value stored in the Width property
- Height
- Value stored in the Height property
- BitOrder
- riboBitsInOrder
- ByteOrder
- riboMSBFirst
- LineOrder
- riloTopToBottom
- BitsPerPixel
- 32
- LineEnd
- rileDWordBoundary
- RedPrec
- 8
- RedShift
- 8
- GreenPrec
- 8
- GreenShift
- 16
- BluePrec

- BlueShift
- 24

FillDescription is used in the implementation of the GetFullRawImage and GetRawImage methods.
