Detailed Description

Buffer manager, for moving through a cube in samples.

This class is used as a manager for moving through a cube one sample buffer at a time. A sample buffer is defined as a one dimensional sub-area of a cube. That is, the number of lines by 1 sample by 1 band (1,nl,1). The manager moves this (1,nl,1) shape through the cube sequentially accessing all the sample buffer in the first band before proceeding to the second band.

◆ SetBaseSample()

◆ SetIncrements()

void Isis::BufferManager::SetIncrements	(	const int	sinc,
		const int	linc,
		const int	binc )

protectedinherited

Sets how the shape is incremented through the cube.

By default (if this method is not invoked) shapes are moved sequentially through the cube with no overlap. For example, assume a 3 sample by 3 line tile buffer. It would first move across the image from left-to-right starting at sample 1, line 1, and band 1. Upon an increment it would be positioned at sample 4, line 1, and band 1. Each successive increment would cause the sample position to increase by 3 until it exceeds the number of samples in the cube. At that point the shape buffer would be positioned at sample 1, line 4, and band 1 (effectively moving to the next row of tiles). The shape would then continue moving across the cube until it reaches the edge again. Then the next row of tiles would be accessed until the shape reached the bottom of the cube. This default management can be overridden using this method. For example, by setting the increments to (6,3,1) we effectively skip every other tile. By setting them to (6,6,1) we skip every other tile and every other row of tiles. By setting them to (1,1,1) we essentially have NSxNLxNB positions in the cube and the 3x3 tile is managed such that the top left corner of the tile is moved over by 1 sample until it reaches the end of the line then down 1 line and so on until the end of the cube is reached.

Parameters

sinc	Sample increment
linc	Line increment
binc	Band increment

Referenced by Isis::BoxcarManager::BoxcarManager(), and Isis::BufferManager::BufferManager().

◆ SetOffsets()

void Isis::BufferManager::SetOffsets	(	const int	soff,
		const int	loff,
		const int	boff )

protectedinherited

Sets the offset of the buffer.

By default (if this method is not invoked) the offsets are (0,0,0). Offsets are applied when computing the top-left corner of the shape buffer. When used in conjunction with the SetIncrements method, this allows for centering shape buffers around a pixel when passing in negative offsets. For example,with a 3x3x1 shape and offsets of (-1,-1,0) and increments of (1,1,1) would cause the manager to walk a 3x3 buffer through the entire image. Setting the manager position the beginning causes the 3x3 window to be positioned such that sample 1, line 1 of the cube would be at the center of the window and increment would cause sample 2, line 1 to be at the center of the window. Successive increments will move the window in the sample direction until the end of line is reached at which time the buffer would be centered on sample 1, line 2.

Parameters

soff	Sample offset
loff	Line offset
boff	Band offset

Referenced by Isis::BoxcarManager::BoxcarManager().

◆ setpos()

bool Isis::BufferManager::setpos ( BigInt map )

inherited

Sets the position of the shape in the cube.

This shape fits into the cube a specific number of times.

When p_reverse is left false: (default) For example, a line shape on a 100 sample, 200 line, and 2 band cube would have 200*2 or 400 different positions as there are 400 total lines in the cube. Performing setpos(0) would position the shape at sample 1, line 1, and band 1. While setpos(200) would position the shape at sample 1, line 1, and band 2. Finally, setpos(399) would position the shape at sample 1, line 400, and band 2. Setpos returns true if it was sucessfully in setting the position, and false if the shape is at the end of the cube (beyond index 399 in the case of our example).

When p_reverse is set to true: Following the above cube with 100 samples, 200 lines, and 2 bands, performing the setpos(0) would still position the shape at sample 1, line 1, and band 1. However, setpos(1) would position the shape at sample 1, line 1, band 2, while setpos(200) would position the spame at sample 1, line 100, band 1. Setpos returns true of it was sucessfully in setting the position, and false if the shape is at the end of the cube(beyond final index).

Parameters

map	Shape buffer position value

Returns: bool True or False depending on whether the shape is at the end of the cube or not.
