The ADDBORDERINFO structure contains information about the border to add to the bitmap.

Member Description
uStructSize Size of this structure in bytes. Use the sizeof() macro to calculate this value.
nLeftThickness The thickness of the left side of the border.
nTopThickness The thickness of the top side of the border.
nRightThickness The thickness of the right side of the border.
nBottomThickness The thickness of the bottom side of the border.
nLocation Flag that indicates the position of the border. Possible values are:
  Value Meaning
  BORDER_INSIDE [0] The border will be within the bitmap. This is the default.
  BORDER_OUTSIDE [1] The border will be outside the bitmap.
nStyle Flag that indicates the style of the border. Possible values are:
  Value Meaning
  BORDER_STYLE_TRANSPARENT [0] The border is transparent. Therefore, the bitmap itself shows through as the border. This is the default.
  BORDER_STYLE_OPAQUE [1] Use a single color to create the border. The color used is crGradientStart.
  BORDER_STYLE_GRADIENT [2] The border contains a color gradient from crGradientStart to crGradientEnd.
  BORDER_STYLE_TILES [3] The border is taken from the bitmap referenced by the pTileBitmap member.
nEffectStyle Flag that indicates the change in the appearance of the border. By default there are no changes. The change also depends on the value of nCurveIntesity. If nCurveIntensity is zero, there are no changes. Possible values are:
  Value Meaning
  BORDER_EFFECT_CURVEDIN [1] Add a 3D appearance to the border by adding a high intensity color to the inner side of the border and a lower intensity color to the outer side of the border.
  BORDER_EFFECT_CURVEDOUT [2] Add a 3D appearance to the border by adding a high intensity color to the outer side of the border and a lower intensity color to the inner side of the border.
  BORDER_EFFECT_RAISED [3] Add a curved appearance to the border.
pTileBitmap Pointer to a bitmap handle that references the tile bitmap. This is the bitmap the border is taken from when nStyle is BORDER_STYLE_TILES.
nGradientStyle Flag that indicates the gradient style. This flag is used only when the nStyle member is BORDER_STYLE_GRADIENT. Possible values are:
  Value Meaning
  BORDER_GRAD_INSIDEOUT [0] The gradient starts from the inside of the border and progresses toward the outside of the border. This is the default.
  BORDER_GRAD_CENTEROUT [1] The gradient starts from the center of the border and progresses toward both the inside and outside of the border.
  BORDER_GRAD_CORNEROUT [2] The gradient starts from the corners of the border.
crGradientStart COLORREF value that specified the starting color when nStyle is BORDER_STYLE_GRADIENT. This is also the color used when nStyle is BORDER_STYLE_OPAQUE.
crGradientEnd COLORREF value that specified the ending color when nStyle is BORDER_STYLE_GRADIENT.
nCurveIntensity Value that indicates the degree to which to change the appearance of the border. This value is used only when the nEffectStyle flag is set. The range is from 1000 to 1000.
bSoftCurve Boolean flag that indicates whether to give the border a soft curve appearance. This flag is used only when nEffectStyle is BORDER_EFFECT_RAISED. Possible values are:
  Value Meaning
  TRUE Make the border more homogeneous in intensity, giving the appearance of a smoother curve.
  FALSE Do not make the border more homogeneous in intensity.
bShadow Boolean flag that indicates whether to add a shadow to the border. Possible values are:
  Value Meaning
  TRUE Add a shadow to the border.
  FALSE Do not add a shadow to the border. This is the default.
nShadowSize Value that indicates the width of the shadow, in pixels. This value is used only when bShadow is TRUE.
nShadowDirection Flag that indicates the direction of the shadow. This value is used only when bShadow is TRUE. Possible values are:
  Value Meaning
  BORDER_SHADOW_LEFT [0] The shadow is on the left top side of the image. This is the default.
  BORDER_SHADOW_RIGHT [1] The shadow is on the right bottom side of the image.
  BORDER_SHADOW_SURROUND [2] The shadow surrounds the border.
bBumpyShadow Boolean flag that indicates whether to increase the intensity near the far edge of the shadow. This flag is used only when bShadow is TRUE. Setting this flag to TRUE produces a good appearance for the shadow if nShadowSize is a value between 4 and 7. Possible values are:
  Value Meaning
  TRUE Increase the intensity near the far edge of the shadow.
  FALSE Do not increase the intensity near the far edge of the shadow.

Comments

This structure is used by the LBitmap::AddBorder function.

LPADDBORDERINFO is a pointer to a ADDBORDERINFO structure. Where a function parameter type is LPADDBORDERINFO, declare an ADDBORDERINFO variable and pass the variable's address in the parameter. Declaring an LPADDBORDERINFO variable is necessary only if the program requires a pointer.

Some functions which take this structure as a parameter require that the structure be initialized prior to the function call. You must set the uStructSize member to the total size, in bytes, of the structure. Use the sizeof() macro to calculate this value. Functions that do not require the structure be initialized will take the total size of the structure, in bytes, as an additional function parameter.

The images below demonstrate some of the borders that are possible, by setting various members and flags.
