Reserved8

These fields are not currently used and must be set to 0.

PicFlags

May set PF_NoDibPad to force zero Stride.

PicFlags2

Not used specifically by this opcode.

Method

Set as indicated by the following table:

Method	Operation
0	Manual color correction
1	Manual lightness correction
2	Auto color correction
3	Auto lightness correction

Stride

Set to the image line width in bytes including padding at the end of the line width. If the stride is left 0 and PF_NoDibPad is not set in PicFlags, the stride will be calculated [ (((Width *BitCount)+31)&(~31))/8 ] to be long word aligned. Deskew assumes padding.

BiOut

If the image is cropped the new image dimensions will be returned in this Bitmap header structure after a successful completion of the OP_ADJUST operation.

Color

Parameter is used for Color Correction. The parameter value is set from 0 to 100 with 0 as the neutral default value.

Red

Parameter is used for Color Correction. The parameter value is set from -100 to 100 with 0 as the neutral default value.

Green

Parameter is used for Color Correction. The parameter value is set from -100 to 100 with 0 as the neutral default value.

Blue

Parameter is used for Color Correction. The parameter value is set from -100 to 100 with 0 as the neutral default value.

Shadows

Parameter is used for Lightness Correction. The parameter value is set from 0 to 100 with 0 as the neutral default value. The larger numbers give brighter shadowed image areas.

Highlights

Parameter is used for Lightness Correction. The parameter value is set from 0 to 100 with 0 as the neutral default value. The larger numbers give darker highlighted image areas.
