Composition operations are found in this class: multi-tile compositor and multi-channel compositor.
◆ ComposeMultiChannel_Bgr24() [1/3]
Create the multi-channel-composite - applying tinting or gradation to the specified bitmaps and write the result to a newly allocated destination bitmap. All source bitmaps must have same width and height, and the destination bitmap will also have this same width/height. The pixeltype of the destination bitmap will be Bgr24.
- Parameters
-
channelCount | The number of channels. |
srcBitmaps | An array of source bitmaps. The array must contain as many elements as specified by channelCount . |
channelInfos | An array of channelInfo for the source channels. The array must contain as many elements as specified by channelCount . |
- Returns
- A std::shared_ptr<IBitmapData>.

All source bitmaps must have same width and height, and the destination bitmap will also have this same width/height. The pixeltype of the destination bitmap will be Bgra32, and each alpha-pixel-value will be set to 'alphaVal'.
- Parameters
-
alphaVal | The alpha value. |
channelCount | The number of channels. |

◆ ComposeSingleChannelTiles()
Composes a set of tiles (which are retrieved by calling the getTiles-functor) in the following way: The destination bitmap is taken to be positioned at (xPos,yPos) - which specifies the top-left corner. The tiles (retrieved from the functor) are positioned at the coordinate as reported by the functor-call. Then the intersection area of source and destination is copied to the destination bitmap. If the intersection is empty, then nothing is copied.
- Parameters
-
getTiles | [in] The functor which is called in order to retrieve the tiles to compose. The second and the third parameter specify the x- and y-position of this tile. We address a tile with the parameter index. If the index is out-of-range, then this functor is expected to return false. |
dest | [in,out] The destination bitmap. |
xPos | The x-coordinate of the top-left of the destination bitmap. |
yPos | The y-coordinate of the top-left of the destination bitmap. |
pOptions | Options for controlling the operation. This argument is optional (may be nullptr). |
