|

|
|
* Image Attributes
|

|
|
*
|
||
|
|
* Abstract:
|
||
|
|
*
|
||
|
|
* GDI+ Image Attributes used with Graphics.DrawImage
|
||
|
|
*
|
||
|
|
* There are 5 possible sets of color adjustments:
|
||
|
|
* ColorAdjustDefault,
|
||
|
|
* ColorAdjustBitmap,
|
||
|
|
* ColorAdjustBrush,
|
||
|
|
* ColorAdjustPen,
|
||
|
|
* ColorAdjustText,
|
||
|
|
*
|
||
|
|
* Bitmaps, Brushes, Pens, and Text will all use any color adjustments
|
||
|
|
* that have been set into the default ImageAttributes until their own
|
||
|
|
* color adjustments have been set. So as soon as any "Set" method is
|
||
|
|
* called for Bitmaps, Brushes, Pens, or Text, then they start from
|
||
|
|
* scratch with only the color adjustments that have been set for them.
|
||
|
|
* Calling Reset removes any individual color adjustments for a type
|
||
|
|
* and makes it revert back to using all the default color adjustments
|
||
|
|
* (if any). The SetToIdentity method is a way to force a type to
|
||
|
|
* have no color adjustments at all, regardless of what previous adjustments
|
||
|
|
* have been set for the defaults or for that type.
