Remarks:

Here are the settings available for nAttributeID as defined in accucnst.h, and what they mean:

lpData is not the address of the data, but a value to which the address should be passed.

  1. If nAttributeID is set to a IG_GUI_DATA_COLOR_COMPONENT constant, then lpData should contain combinations of following flags:
    • IG_GUI_COLOR_COMPONENT_R: show chart for Red component
    • IG_GUI_COLOR_COMPONENT_G: show chart for Green component
    • IG_GUI_COLOR_COMPONENT_B: show chart for Blue component
    • IG_GUI_COLOR_COMPONENT_I: show chart for Intensity

    The ImageGear default value for IG_GUI_DATA_COLOR_COMPONENT is:

    IG_GUI_COLOR_COMPONENT_R | IG_GUI_COLOR_COMPONENT_G | IG_GUI_COLOR_COMPONENT_B

  2. If nAttributeID is set to a constant, then lpData should contain a combination of the following flags:
    • IG_GUI_COLORPROFILE_STYLE_STACK - Draw stacked chart. Each chart bottom is the top of the previous chart.
    • IG_GUI_COLORPROFILE_STYLE_SEPARATE - Draw each chart in separate area. Each chart has its own base line
    • IG_GUI_COLORPROFILE_STYLE_OVERLAID - Draw one chart over previous. Only one of the styles listed above may be specified.
    • IG_GUI_COLORPROFILE_STYLE_TRACK-- Draw line following the mouse
    • IG_GUI_COLORPROFILE_STYLE_XY-- Show mouse cursor coordinates in the GUI window.

    The default ImageGear setting for IG_GUI_DATA_COLORPROFILE_STYLE is:

    IG_GUI_COLORPROFILE_STYLE_TRACK |IG_GUI_COLORPROFILE_STYLE_SEPARATE
