readPsdImpl()

bool PSDLayerMaskSection::readPsdImpl ( QIODevice & io )

private

PSD files created in some weird web applications may have invalid layer-mask-block-size set. Just do a simple sanity check to catch this case

Newer versions of PSD have layers info block wrapped into 'Lr16' or 'Lr32' additional section, while the main block is absent.

Here we pass the callback which should be used when such additional section is recognized.

Just like PSD, new versions of PSD have layers info block wrapped into 'Lr16' or 'Lr32' additional section, while the main block is absent. Additionally, the global mask info is stored in a separate "LMsk" block.

So, instead of having special handling, we just ship everything to the additional layer info block handlers
