public class AVI_Writer
extends Object
implements PlugInFilter

This plugin implements the File/Save As/AVI command. Supported formats: Uncompressed 8-bit (gray or indexed color), 24-bit (RGB), JPEG and PNG compression of individual frames 16-bit and 32-bit (float) images are converted to 8-bit The plugin is based on the FileAvi class written by William Gandler, part of Matthew J. McAuliffe's MIPAV program, available from http://mipav.cit.nih.gov/. 2008-06-05: Support for jpeg and png-compressed output and composite images by Michael Schmid. 2015-09-28: Writes AVI 2.0 if the file size would be above approx. 0.9 GB The AVI format written looks like this: RIFF AVI RIFF HEADER, AVI CHUNK | LIST hdrl MAIN AVI HEADER | | avih AVI HEADER | | LIST strl STREAM LIST(s) (One per stream) | | | strh STREAM HEADER (Required after above; fourcc type is 'vids' for video stream) | | | strf STREAM FORMAT (for video: BitMapInfo; may also contain palette) | | | strn STREAM NAME | | | indx MAIN 'AVI 2.0' INDEX of 'ix00' indices | LIST movi MOVIE DATA (maximum approx. 0.95 GB) | | 00db or 00dc FRAME (b=uncompressed, c=compressed) | | 00db or 00dc FRAME | | ... | | ix00 AVI 2.0-style index of frames within this 'movi' list RIFF AVIX Only if required by size (this is AVI 2.0 extension) | LIST movi MOVIE DATA (maximum approx. 0.95 GB) | | 00db or 00dc FRAME | | ... | | ix00 AVI 2.0-style index of frames within this 'movi' list RIFF AVIX further chunks, each approx 0.95 GB (AVI 2.0) ...

Method Details

setup

public int setup(String arg, ImagePlus imp)

Description copied from interface: PlugInFilter

This method is called once when the filter is loaded. 'arg', which may be blank, is the argument specified for this plugin in IJ_Props.txt or in the plugins.config file of a jar archive containing the plugin. 'imp' is the currently active image. This method should return a flag word that specifies the filters capabilities.

For Plugin-filters specifying the PlugInFilter.FINAL_PROCESSING flag, the setup method will be called again, this time with arg = "final" after all other processing is done.

Specified by:

setup in interface PlugInFilter

run

public void run(ImageProcessor ip)

Asks for the compression type and filename; then saves as AVI file

Specified by:

run in interface PlugInFilter

writeImage

public void writeImage(ImagePlus imp, String path, int compression, int jpegQuality) throws IOException

Writes an ImagePlus (stack) as AVI file.

Throws:

IOException
