Interface ImageExporter

public interface ImageExporter

ImageExporters are used to generate linear sequences of images-as-rendered by a DisplayWindow. Thus they include the current image scaling, any overlays, et cetera.

Method Detail

setDisplay

void setDisplay(DisplayWindow display)

Set the display to use for image exporting. The same ImageExporter may be re-used for multiple displays, if desired.

Parameters:

display - Display to use for exporting images.

setOutputFormat

void setOutputFormat(ImageExporter.OutputFormat format)

Set the output format to use.

Parameters:

format - The format to output in.

setOutputQuality

void setOutputQuality(int quality)

Set the image quality. This is currently only relevant if the output format is OUTPUT_JPG.

Parameters:

quality - An integer quality ranging from 1 through 100. The default value is 90.

setSaveInfo

void setSaveInfo(java.lang.String path,
                 java.lang.String prefix)
          throws java.io.IOException

Set the path to save images to, and the filename prefix to use when saving images. These values are ignored if the output format is set to OUTPUT_IMAGEJ.

Parameters:

path - Directory in which images will be placed

prefix - String to place at beginning of each output image's name.

Throws:

java.lang.IllegalArgumentException - if the directory does not exist.

java.io.IOException

loop

ImageExporter loop(java.lang.String axis,
                   int start,
                   int stop)

Add a new "inner loop" to the export parameters. This determines what order the images will be output in. For example: exporter.loop(Coords.Z, 0, 10).loop(Coords.CHANNEL, 0, 2) This will cause the channel axis to be the "inner loop", changing most frequently, and the Z axis to be the "outer loop", changing least frequently.

Parameters:

axis - Axis name, like Coords.CHANNEL, Coords.Z, etc.

start - Axis index to start exporting from, inclusive.

stop - Axis index to stop exporting from, exclusive (i.e. one more than the index of the last image you want to export).

Returns:

This instance, allowing calls to be chained together.

resetLoops

void resetLoops()

Reset the current export loop parameters to empty.

export

void export()
     throws java.io.IOException,
            java.lang.IllegalArgumentException

Run the export process. This will generate the image sequence as configured previously by calling setOutputFormat, setSaveInfo, and loop. Only one export is allowed to run at a time; if a second export is started, it will block until the first has finished. Otherwise, this method will return immediately. If you want to wait for exporting to finish, call the waitForExport() method. NOTE: the exporter will silently ignore the following "configuration errors": - Setting a save path when using the OUTPUT_IMAGEJ format - Loops over axes that are not used by any images in the display's datastore - Loops that have invalid start/end boundary conditions (starting or ending index is greater than largest index in the datastore). In the latter two cases, image coordinates that do not refer to a valid image will be ignored (for example, trying to access a Z coordinate of 1 in a dataset that is two-dimensional). It is therefore possible that this method will not actually do anything, if none of the loops encompass valid image coordinates.

Throws:

java.io.IOException - if the export process would attempt to write to a file that already exists

java.lang.IllegalArgumentException - if no output format has been set, or OUTPUT_PNG or OUTPUT_JPG formats are used but no save information has been set, or if no loops have been configured, or if no display has been set.

waitForExport

void waitForExport()
            throws java.lang.InterruptedException

Block until a prior call to export() returns. Returns immediately if no export is currently running.

Throws:

java.lang.InterruptedException - if the thread was interrupted while waiting.
