void BitmapImage::autoCrop | ( | ) |
Removes any transparent borders by reducing the boundaries.
This function reduces the bounds of an image until the top and bottom rows, and the left and right columns of pixels each contain at least one pixel with a non-zero alpha value (i.e. non-transparent pixel). Both mBounds and the size of #mImage are updated.

Compare colors for the purposes of flood filling.
Calculates the Eulcidian difference of the RGB channels of the image and compares it to the tolerance
[in] | newColor | The first color to compare |
[in] | oldColor | The second color to compare |
[in] | tolerance | The threshold limit between a matching and non-matching color |
[in,out] | cache | Contains a mapping of previous results of compareColor with rule that cache[someColor] = compareColor(someColor, oldColor, tolerance) |

Finds all pixels closest to the input color and applies the input color to the image.
An example:
0 is where the color was found 1 is the distance from the nearest pixel of that color

Determines if the BitmapImage is minimally bounded.
A BitmapImage is minimally bounded if all edges contain at least 1 non-transparent pixel (alpha > 0). In other words, the size of the image cannot be decreased without cropping visible data.

Updates the bounds after a draw operation with the composition mode cm.
[in] | sourceBounds | The bounds of the source used for drawcall. |
[in] | isSourceMinBounds | Is sourceBounds the minimal bounds for the source image |
[in] | cm | The composition mode that will be used for the draw image |
For a call to draw image of a QPainter (initialized with mImage) with an argument of source, this function intelligently calculates the bounds. It will attempt to preserve minimum bounds based on the composition mode.
This works baed on the principle that some minimal bounds can be determined solely by the minimal bounds of this and source, depending on the value of cm. Some composition modes only expand, or have no affect on the bounds.
