my DNG images, converted with Adobe Camera Raw from my Panasonic Lumix DMC-FZ18 RAW images, always showed up fine in the DOpus standalone viewer. Now I converted a bunch of RAW files with Lightroom 4 and the following settings:
Compatibility: Camera Raw 6.6 and later
JPEG Preview: Full Size
Embed Fast Load Data
(no lossy compression, no embedded RAW file)
When I try to display these DNG files in the standalone viewer or the viewer pane, the images are distorted, obviously there are several "stripes" missing in the displayed image (the RAW image plugin's image mode is set to "Full decode"; otherwise it works, of course). I've added two screenshots, taken from the standalone viewer. In landscape oriented images, the black part is at the bottom of the image.
The thumbnails in DOpus are correct, and the DNG files can be viewed in Lightroom 4 (at least this program should fully decode the file, too), ACDSee 14 and Geosetter 3.4.29 Beta without a problem.
Can anyone confirm this problem? Or am I the only one encountering it?
Yes, of course. As it seems, it's too big for a PM (~8 MB, also tried a ZIP file, but that's not much smaller). Should I send it to the address listed on the page gpsoft.com.au/footer/contact.html (info@...)?
I can confirm the problem, and have also checked that it happens using the DCRaw tool which the Opus Raw viewer (and most other Raw viewers) is based on, and it does.
I found a thread from another photo tool's forum which says that Adobe changed the DNG format in Lightroom 4 and the DCRaw code does not yet support the new format. So I think we just have to wait. If support is added to DCRaw then I will integrate the changes into the Opus plugin.
FWIW, if you reset the plugin to its default settings, so that it shows the preview image rather than a full-decode in the the viewer, then the file will look fine. (It'll still go wrong if you use Opus to convert it to another format, since conversion defaults to doing a full-decode. You could set up the plugin to use the preview image for conversion as well, if you like. In this case the preview image is high-res and high-quality so the full-decode is not really needed for general file management, but may still be desired for doing a high-quality conversion.)

Okay, no problem. I just wasn't sure if it's a problem caused by the plugin or by some other component used by the plugin. I guess it won't be too long until this is fixed in DCRaw.
Yes, I aready stated that in my initial posting. I'll use that setting until the plugin gets fixed.
A DCRaw update has come out which seems to add support for the new DNG images (or at least the test image you sent). Look for an updated plugin in the next update.
