EGDIPException

Base exception class for RiverSoftAVG GDI+ library

TRSGPColor

TRSGPColor is used to specify alpha colors for the GDI+ library.

TRSGPColor is used to specify the alpha color to be displayed for a visual component. It is used by the Color property of many components and by a number of other properties that specify color values.

Alpha colors constants are defined by the TRSGPColorRec record. The unit also contains definitions of useful constants for TRSGPColor. The names of the constants are composed of the clx prefix and the color names defined by the TRSGPColorRec record. These constants map directly to the closest matching color in the system palette (for example, clxBlue maps to blue).

TRSGPColor is formed of four channels (ARGB) specified as 4-byte hexadecimal number. The low three bytes represent RGB color channels, intensities for blue, green, and red, respectively, and the highest-order byte is the transparency coefficient (Alpha channel). The value $FFFF0000 (Delphi) or 0xFFFF0000 (C++) represents full-intensity, pure blue, $FF00FF00 (Delphi) or 0xFF00FF00 (C++) is pure green, and $FF0000FF (Delphi) or 0xFF0000FF (C++) is pure red. $FF000000 (Delphi) or 0xFF000000 (C++) is black and $FFFFFFFF (Delphi) or 0xFFFFFFFF (C++) is white.

For a list of the predefined colors, see TRSGPColorRec.

Record for information about a GDI+ bitmap

TRSGPColorKey

Defines the low and high colors for a color key range

TRSGPColorMap

TRSGPColorMatrix

A 5×5 color matrix is a homogeneous matrix for a 4-space transformation. The element in the fifth row and fifth column of a 5×5 homogeneous matrix must be 1, and all of the other elements in the fifth column must be 0. Color matrices are used to transform color vectors. The first four components of a color vector hold the red, green, blue, and alpha components (in that order) of a color. The fifth component of a color vector is always 1.

TRSGPColorRec

Defines a list of color constants for the GDI+ library. It also provides implicit conversions between other color types (TColor, TAlphaColor) in the Delphi libraries.

You can adjust the colors in a rendered image by passing the address of an TRSGPImageAttributes object to the TRSGPCanvas.DrawImage method. An TRSGPImageAttributes object maintains color and grayscale settings for five adjustment categories: default, bitmap, brush, pen, and text. Several of the methods of the TRSGPImageAttributes class receive an element of the TRSGPColorAdjustType enumeration to specify the adjustment category.
