The Compression type exposes the following members.
Properties
Name | Description | |
---|---|---|
![]() | BitOrderCodes |
Used for CCITT data compression only. Indicates the bit order representation of the stored
compressed codes.
ICAP_BITORDERCODES
|
![]() | CcittKFactor |
Used for CCITT Group 3 2-dimensional compression.The ‘K’ factor indicates how often the new
compression baseline should be re-established.A value of 2 or 4 is common in facsimile
communication.A value of zero in this field will indicate an infinite K factor—the baseline is only
calculated at the beginning of the transfer.
ICAP_CCITTKFACTOR
|
![]() | JpegPixelType |
Allows the application and Source to agree upon a common set of color descriptors that are made
available by the Source.This ICAP is only useful for JPEG-compressed buffered memory image
transfers.
ICAP_JPEGPIXELTYPE
|
![]() | JpegQuality |
Use this capability as a shortcut to select JPEG quantization tables that tradeoff quality versus
compressed image size. Used in concert with DAT_JPEGCOMPRSSION it is possible for an
Application to obtain the tables that are appropriate for varying percentages of quality within a
given Source.
ICAP_JPEGQUALITY
|
![]() | JpegSubSampling |
Use this capability and JpegQuality as a shortcut to select JPEG quantization.
ICAP_JPEGSUBSAMPLING
|
![]() | Method |
Compression method for Buffered Memory Transfers and File transfers.
ICAP_COMPRESSION
|
![]() | PixelFlavorCodes |
Sense of the pixel whose numeric value is zero (minimum data value).
ICAP_PIXELFLAVORCODES
|
![]() | TimeFill |
Used only with CCITT data compression. Specifies the minimum number of words of
compressed codes(compressed data) to be transmitted per line.
ICAP_TIMEFILL
|
