The MOSAICTILESINFO structure provides the information needed for the LBitmap::MosaicTiles Function.
| 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. | ||
| 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. | |
| 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. | |
