A comment block is -added to the file. -.PP -The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. -Although the standard doesn't actually define what COM blocks are for, they -are widely used to hold user-supplied text strings. This lets you add -annotations, titles, index terms, etc to your JPEG files, and later retrieve -them as text. COM blocks do not interfere with the image stored in the JPEG -file. The maximum size of a COM block is 64K, but you can have as many of -them as you like in one JPEG file. -.PP -.B wrjpgcom -adds a COM block, containing text you provide, to a JPEG file. -Ordinarily, the COM block is added after any existing COM blocks; but you -can delete the old COM blocks if you wish. -.SH OPTIONS -Switch names may be abbreviated, and are not case sensitive. -.TP -.B \-replace -Delete any existing COM blocks from the file. -.TP -.BI \-comment " text" -Supply text for new COM block on command line. -.TP -.BI \-cfile " name" -Read text for new COM block from named file. -.PP -If you have only one line of comment text to add, you can provide it on the -command line with -.BR \-comment . -The comment text must be surrounded with quotes so that it is treated as a -single argument. Longer comments can be read from a text file. -.PP -If you give neither -.B \-comment -nor -.BR \-cfile , -then -.B wrjpgcom -will read the comment text from standard input. (In this case an input image -file name MUST be supplied, so that the source JPEG file comes from somewhere -else.) You can enter multiple lines, up to 64KB worth. Type an end-of-file -indicator (usually control-D) to terminate the comment text entry. -.PP -.B wrjpgcom -will not add a COM block if the provided comment string is empty. Therefore -\fB\-replace \-comment ""\fR can be used to delete all COM blocks from a file. -.SH EXAMPLES -.LP -Add a short comment to in.jpg, producing out.jpg: -.IP -.B wrjpgcom \-c -\fI"View of my back yard" in.jpg -.B > -.I out.jpg -.PP -Attach a long comment previously stored in comment.txt: -.IP -.B wrjpgcom -.I in.jpg -.B < -.I comment.txt -.B > -.I out.jpg -.PP -or equivalently -.IP -.B wrjpgcom -.B -cfile -.I comment.txt -.B < -.I in.jpg -.B > -.I out.jpg -.SH SEE ALSO -.BR cjpeg (1), -.BR djpeg (1), -.BR jpegtran (1), -.BR rdjpgcom (1) -.SH AUTHOR -Independent JPEG Group -- cgit v1.2.3
