Member |
Description |
||
uStructSize |
Size of this structure, in bytes. Use the sizeof operator to calculate this value. |
||
uOpacity |
Value that represents the weight, in percent, given to the image color and the border or tile color when determining the resulting color. For example, if uOpacity = 75, then 75% of the image color will be added to 75% of the border (or Tile) color. Final results are clipped if greater than 255. Possible values are from 0 to 100. |
||
uPenWidth |
Value that indicates the width of the pen used to draw tile boundaries, in logical units. Possible values range from 1 to 15. The pen uses the crBorderColor. |
||
uTileWidth |
Value that represents the width of the tile. The meaning of uTileWidth differs according to the flags that are set in the uFlags member. Possible values are: |
||
|
If uFlags contains |
uTileWidth represents |
Valid Range |
|
MSCT_CART |
The width of each rectangular tile, in pixels. |
1 to the image width, if there is no region. If there is a region, then the range of values is 1 to the region width. |
|
MSCT_POLAR |
The size, in degrees, of the curve in the arc-shaped tiles. That is, the circle around the ptCenter is divided into tiles of uTileWidth degrees, as shown below: |
1 to 360. The circle can be divided into tiles from 1 degree to 360 degrees. |
uTileHeight |
Value that represents the height of the tile. The uTileHeight differs according to the flags that are set in the uFlags member. Possible values are: |
||
|
If uFlags contains |
uTileHeight represents |
Valid Range |
|
MSCT_CART |
The height of each rectangular tile, in pixels. |
1 to the image height, if there is no region. If there is a region, then the range of values is 1 to the region height. |
|
MSCT_POLAR |
The radial length of each arc-shaped tile, in pixels. |
1 to the diagonal of the image, if there is no region. If there is a region, then the range of values is 1 to the diagonal of the region rectangle. |
ptCenter |
Point that represents the center of revolution when polar coordinates are used. This parameter is used if MSCT_POLAR is set in uFlags. |
uFlags |
Flags that indicate whether to use arc-shaped or rectangular-shaped tiles, and what type of shadowing to use, if any. You can use a bit wise OR (|) to specify one flag from each group. |
|
|
The following flags indicate which tile shape should be used: |
|
|
Value |
Meaning |
|
MSCT_CART |
[0x0000] Draw rectangular tiles. If this flag is used, uTileWidth contains the tile width in pixels, and uTileHeight contains the tile height in pixels. |
|
MSCT_POLAR |
[0x0001] Draw arc-shaped tiles. If this flag used, uTileWidth contains the size of the curve in the tiles in degrees, and uTileHeight contains the radial length of the tiles (in pixels). |
|
The following are the flags indicate how to apply the shadow on the tiles, or whether to use shadows: |
|
|
Value |
Meaning |
|
MSCT_FLAT |
[0x0000] Do not apply a shadow. |
|
MSCT_SHADOWRGB |
[0x0010] Apply colored shadows. |
|
MSCT_SHADOWGRAY |
[0x0020] Apply grayscale shadows. |
uShadowAngle |
Value indicating the direction of the light source that produces the shadow. This parameter is used if the MSCT_SHADOWRGB flag or the MSCT_SHADOWGRAY flag is set in uFlags. Possible values are: |
|
|
Value |
Meaning |
|
SHADOW_E |
[0x0000] East |
|
SHADOW_NE |
[0x0001] Northeast |
|
SHADOW_N |
[0x0002] North |
|
SHADOW_NW |
[0x0003] Northwest |
|
SHADOW_W |
[0x0004] West |
|
SHADOW_SW |
[0x0005] Southwest |
|
SHADOW_S |
[0x0006] South |
|
SHADOW_SE |
[0x0007] Southeast |
uShadowThreshold |
Value that determines which pixels will be affected by the shadow. Possible values range from 0 through 255. Pixel values less than the threshold value will be unaffected. This member will be used if the MSCT_SHADOWRGB flag or the MSCT_SHADOWGRAY flag is set in uFlags. |
|
crBorderColor |
The COLORREF value that specifies the transparency fill color for the tile border areas. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color. |
|
crTilesColor |
The COLORREF value that specifies the transparency fill color for the tiles. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color. |
