Description

EMR_COLORCORRECTPALETTE

2.3.8.1

Specifies how to correct the entries of a LogPalette object (section 2.2.17) by using WCS values.

EMR_DELETECOLORSPACE

2.3.8.2

Specifies how to delete a logical color space from the EMF object table (section 3.1.1.1).

EMR_DELETEOBJECT

2.3.8.3

Specifies the index of the object to be deleted from the EMF object table.

EMR_RESIZEPALETTE

2.3.8.4

Increases or decreases the size of an existing LogPalette object.

EMR_SELECTOBJECT

2.3.8.5

Specifies an existing object based on its index in the EMF object table and selects it into the playback device context

EMR_SELECTPALETTE

2.3.8.6

Selects the specified LogPalette object into the playback device context.

EMR_SETCOLORSPACE

2.3.8.7

Specifies a logical color space, based on its index in the EMF object table.

EMR_SETPALETTEENTRIES

2.3.8.8

Defines RGB color values in a range of entries for an existing LogPalette object.

The generic structure of object manipulation records is specified as follows.

AlignmentPadding (variable, optional)

...

ObjectRecordParm (variable): An array of bytes that contains the parameters for the object manipulation record.

AlignmentPadding (variable, optional): An array of up to 3 bytes that pads the record so that its total size is a multiple of 4 bytes. This field MUST be ignored.
