-----------------------------------
Summary: ImageIOUtil, JPEGUtil, TIFFUtil and MetaUtil are not
needed in "pdfbox"
Key: PDFBOX-2387
URL: https://issues.apache.org/jira/browse/PDFBOX-2387
Project: PDFBox
Issue Type: Improvement
Reporter: John Hewson
The classes ImageIOUtil, JPEGUtil, TIFFUtil and MetaUtil are not needed in the
"pdfbox" module. All usages of ImageIOUtil in the "pdfbox" module can be safely
replaced with Java's ImageIO. That's over 650 lines of imaging code which we
don't need.
ImageIOUtil and friends are only needed by classes in the "tools" module, which
write image files to disk. Ultimately the ImageIOUtil class is just a bandaid
for Java ImageIO's bugs, which while helpful, isn't a necessary part of the
PDFBox core.
Obviously ImageIOUtil is useful to downstream consumers of PDFBox, but it
doesn't belong in the core "pdfbox" module, where it introduces unnecessary
complexity, so we should move it into the "tools" module along with JPEGUtil,
TIFFUtil and MetaUtil.
We might want to consider doing this with other utility classes which probably
don't belong in the "pdfbox" core such as TextToPDF, PrintPDF, WriteDecodedDoc,
etc. - basically anything with a main() method. But we'll deal with that later.
