Hello, I'm DaeHyun Sung, from South Korea. I found the Bugzilla report "tdf#144747 FILEOPEN When opening any Hancom Word hwp document garbage is displayed" https://bugs.documentfoundation.org/show_bug.cgi?id=144747 (Thanks Ming Hua to inform me. )
So, I read hwpfilter module on LibreOffice. LibreOffice only supported hwp v3.0(HWP97 version) file format. However, In Korea, Broadly used to hwp v5.0 file format. It is zipped Compound File Binary Format. So, I added read & check zipped format I submitted my works on gerrit (WIP) https://gerrit.libreoffice.org/c/core/+/125782 Though, I added a check zip file format code. But, It doesn't check and error. Below is added my code === uno::Reference<uno::XComponentContext> xContext = comphelper::getProcessComponentContext(); SAL_WARN("HwpImportFilter::detect", "xContext"); uno::Reference<packages::zip::XZipFileAccess2> xZip( packages::zip::ZipFileAccess::createWithURL(xContext, sURL)); if (xZip.is()) { SAL_WARN("HwpImportFilter::detect", "That maybe HWP v5.0 format"); uno::Reference<io::XInputStream> const isHwpV5FileHeaderStream(xZip->getByName("FileHeader"), uno::UNO_QUERY); } === In my opinion, I found the reading zip module follows LibreOffice core source codes. But It doesn't works. So, I have a question. How to check Zipped file(It contained Compound File Binary Format) on LibreOffice? Check it please! Below is after opening hwp v5 file log. ======== warn:sfx.dialog:157960:158136:sfx2/source/dialog/filtergrouping.cxx:357: already have an element for WordPerfect
