+Subject: fix DPI info in 16-bit PNG
+
+REVIEW:129988
+
+Skanlite tries to save 16bit PNG files on its own in its KSaneImageSaver class because KSaneWidget (part of libksane) uses QImage to save files and QImage doesn't support 16bit images. Related warning in [libksane](https://github.com/KDE/libksane/blob/master/src/ksanewidget.h#L118)
+
+But Skanlite doesn't add most of optional PNG headers to the exported png file. In particulary it misses pHYs (Physical Pixel Dimensions) info. Without it ScanTailor app can't detect scan's dpi and forces user to choose it manually while png file importing. [Related issue in scantailor](https://github.com/scantailor/scantailor/issues/250)
+I've fixed this by adding pHYs to 16bit png based on KSaneWidget::currentDPI() as KSaneWidget [do it itself](https://github.com/KDE/libksane/blob/master/src/ksanewidget.cpp#L627)

+Subject: Bugfix: wrong folder selection dialog behavior
+
+REVIEW:129989
+
+There are 2 problems with directory selection dialog.
+1. If you scan very first page you'll get SaveLocation dialog but if you press the "..." button in it to specify folder for scans - a file selection dialog will be opened. Not directory selection, but file selection.  If you select a file in it - a directory selection dialog pop up just after you close previous one. So you'll get a second dialog. Your first file selection result will be overwritten by folder selection.
+2. If you choose for example "/tmp/" in directory selection dialog you'll get "/tmp" in the text box. Without trailing path separator. And resulted filename preview will be "/prefix-0001.png", not "/tmp/prefix-0001.png". If you didn't notice that and press ok you'll get an error as nothing can be saved to root. If you selected another folder you later may realize that your scans are in parent directory. Why? Bcs SkanLite doesn't check trailing path separator in directory path and believes that "/tmp" is a file tmp in the root folder. And Qt's directory selection dialogs always return directory name without trailing path separator in it.
+
+I've fixed both problems.
+Second one is easy, just `if (!dir.endsWith(QDir::separator())) dir = dir.append(QDir::separator());` before proceeding with directory selection results.
+
+First one is a bit awkward. There is a slot `getDir()` and 2 widgets connected to it. `u_urlRequester` from SaveLocation dialog and `getDirButton` from Settings dialog. the slot opens QFileDialog::getExistingDirectory(). It's fine for getDirButton which is a QButton. But u_urlRequester is a KUrlRequester and contains own button and launches own file selection dialog which is for files by default. That's obviously wrong.
+There are notes in  `getDir()` slot about `// FIXME KF5`. Seems to be [this](https://mail.kde.org/pipermail/kde-frameworks-devel/2014-March/013276.html) discussion. I believe it's irrelevant to this problem. Perhaps this problem is a former workaround for KF5 problem which is already disappeared.
+
+All you need to fix this behavior is to disconnect KUrlRequester from getDir() which explicitly calls getExistingDirectory() and let it use it's own. We just need to switch it in directory selection mode with `u_urlRequester->setMode(KFile::Directory);`.
