Class LoadFileImageSequence<T extends boofcv.struct.image.ImageBase<T>>

java.lang.Object

boofcv.io.wrapper.images.LoadFileImageSequence<T>

All Implemented Interfaces:

SimpleImageSequence<T>

public class LoadFileImageSequence<T extends boofcv.struct.image.ImageBase<T>>
extends java.lang.Object
implements SimpleImageSequence<T>

Loads all the images in a directory that have the specified suffix. If requested it can scale the images down. The order in which the images are returned is determined by Collections.sort() by file name.

Constructor Detail

LoadFileImageSequence

public LoadFileImageSequence(boofcv.struct.image.ImageType<T> type,
                             java.lang.String directory,
                             java.lang.String suffix)

Will load an image sequence with no modification.

Parameters:

directory - The directory containing the images.

suffix - The suffix that the images have.

LoadFileImageSequence

public LoadFileImageSequence(boofcv.struct.image.ImageType<T> type,
                             java.lang.String directory,
                             java.lang.String suffix,
                             int scalefactor)

Will load an image sequence and then scale the images

Parameters:

directory - The directory containing the images.

suffix - The suffix that the images have.

scalefactor - How much the images will be scaled down by.

Method Detail

setLoop

public void setLoop(boolean loop)

Description copied from interface: SimpleImageSequence

Sets if the video should loop or not

Specified by:

setLoop in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

Parameters:

loop - true for looping forever, false for once

isLoop

public boolean isLoop()

getNextWidth

public int getNextWidth()

Description copied from interface: SimpleImageSequence

Returns the width of the next image

Specified by:

getNextWidth in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

getNextHeight

public int getNextHeight()

Description copied from interface: SimpleImageSequence

Returns the height of the next image

Specified by:

getNextHeight in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

hasNext

public boolean hasNext()

True if there is another image to read and false if there are no more.

Specified by:

hasNext in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

Returns:

true if a new image is available.

next

public T next()

Loads the next image into a BufferedImage and returns it. The same instance or a new instance of a BufferedImage might be returned each time. Don't rely on either behavior being consistent.

Specified by:

next in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

Returns:

A BufferedImage containing the next image.

getGuiImage

public java.awt.image.BufferedImage getGuiImage()

Description copied from interface: SimpleImageSequence

Returns the image in the original format that it was read in as. When dealing with swing or any standard Java SE environment this will almost always be BufferedImage. The type has been abstracted out to provide better Android support.

Specified by:

getGuiImage in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

Returns:

getImageType

public boofcv.struct.image.ImageType<T> getImageType()

Description copied from interface: SimpleImageSequence

Returns the type of class used to store the output image

Specified by:

getImageType in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

getFrameNumber

public int getFrameNumber()

Description copied from interface: SimpleImageSequence

Returns the number of the current frame in the sequence.

Specified by:

getFrameNumber in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

Returns:

Frame ID number.

close

public void close()

Description copied from interface: SimpleImageSequence

Call when done reading the image sequence.

Specified by:

close in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

reset

public void reset()

Description copied from interface: SimpleImageSequence

Start reading the sequence from the start

Specified by:

reset in interface SimpleImageSequence<T extends boofcv.struct.image.ImageBase<T>>

getIndex

public int getIndex()

setIndex

public void setIndex(int index)
