ImageMagick is a great tool to create, edit, compose, or convert images. I was working on converting DNG files into JPG using ImageMagick and convert command was throwing following errors.
unable to open image
no images defined
After spending several hours I found ImageMagick uses other programs to read some image formats including DNG. One of such program is Unidentified Flying Raw (UFRaw) which is a utility to read and manipulate raw images from digital cameras.
When you can not sort out errors listed above while converting your DNG images then install UFRaw and see the magic of ImageMagick again.. 🙂
