Parameters
imageattr
[in] Pointer to the
ImageAttributes
object.
type
[in] Element of the
ColorAdjustType
enumeration that specifies the category for which the color-remap table
is set. The default value is ColorAdjustTypeDefault.
enableFlag
[in] Boolean value that specifies
whether a separate color remap table is enabled for the category
specified by the type parameter.
mapSize
[in] Long integer value that specifies the
number of elements in the map array.
map
[in]
Pointer to an array of
ColorMap
structures that defines the color map.
Remarks
A
color-remap table is an array of ColorMap structures.
Each ColorMap structure
has two ARGB colors:
one that specifies an old color and one that specifies a corresponding new color.
During rendering, any color that matches one of the old colors in the remap
table is changed to the corresponding new color.
An
ImageAttributes object
maintains color and grayscale settings for five adjustment
categories: default, bitmap, brush, pen, and text. For
example, you can specify a color remap for the default
category, a color-remap table for the bitmap category,
and still a different color-remap table for the pen category.
The
default color- and grayscale-adjustment settings apply
to all categories that don't have adjustment settings of their own.
For example, if you never specify any adjustment settings for the pen
category, then the default settings apply to the pen category.
As
soon as you specify a color- or grayscale-adjustment setting
for a certain category, the default adjustment settings
no longer apply to that category. For example, suppose
you specify a collection of adjustment settings for the
default category. If you set the color-remap table for
the pen category by passing ColorAdjustTypePen to
the
GdipSetImageAttributesRemapTable function,
then none of the default adjustment settings will apply
to pens.
