Member Function Documentation

◆ autoCrop()

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.

Precondition: mBounds.size() == mImage->size()

Postcondition: Either the first and last rows and columns all contain a pixel with alpha > 0 or mBounds.isEmpty() == true; isMinimallyBounded() == true

inlinestatic

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

Parameters

[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)

Returns: Returns true if the colors have a similarity below the tolerance level (i.e. if Eulcidian distance squared is <= tolerance)

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.

Returns: True only if bounds() is the minimal bounding box for the contained image.

◆ setCompositionModeBounds() [1/2]

void BitmapImage::setCompositionModeBounds	(	BitmapImage *	source,

Updates the bounds after a drawImage operation with the composition mode cm.

Parameters

[in]	source	The source image used for the drawImage call.
[in]	cm	The composition mode that will be used for the draw image

See also: BitmapImage::setCompositionModeBounds(BitmapImage, QPainter::CompositionMode)

Definition at line 354 of file bitmapimage.cpp.

◆ setCompositionModeBounds() [2/2]

void BitmapImage::setCompositionModeBounds	(	QRect	sourceBounds,
		bool	isSourceMinBounds,
		QPainter::CompositionMode	cm
	)

protected

Updates the bounds after a draw operation with the composition mode cm.

Parameters

[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.

Warning: The draw operation described by the arguments of this function needs to be called after this function is run, or the bounds will be out of sync. If mBounds is null, no draw operation needs to be performed.
