Hi, I'm using Magick++ to read/write images from/to files (version 6.9.1-4) and everything is working fine. Now, I need to "ping" the file to get basic information about an image file without reading/loading all the image pixels. I simply need to read the file headers. I know there's a ping function ...

Thanks for your replies! Here's the reason why I'm interested in those bit depths. I'm developing a lightweight image and video processing tool and I'm currently adding support for different image bit depths. So at the end, I'm not the one who might use those numbers. I simply want my software to be ...

Hi there, I was able to write tiff files with bit depth of 8 and 16, both using Magick++ (6.9.1-4) and from the command line (6.9.1-1) and view those images using other image viewers (Nuke, Paint.Net, Autodesk Maya built-in image viewer and Gimp). I was also able to write tiff files with bit depth ...

That's awesome. I have been trying all possible combinations using 'attribute' but never thought about using 'artifact'. It worked like a charm.

Thank you, you made my day!

Hi! I just PM you a link to a DPX example file. Thank you. I was in fact able to write DPX metadata to a DPX file using something like: Magick::Image image image.defineValue( "dpx", "file.creator", "Julie Santerre" ); image.read( inputFilename ); image.write( outputFilename ); Note that the metadata ...

Thank you very much Dirk! This might be the path I will follow.

Do you think I could do something similar to write metadata to DPX file?

(I would need to support the DPX properties described here: http://www.imagemagick.org/script/motion-picture.php)

Thanks!

For the sake of others that would need to do the same... I was able to iterate through the list of all attributes of a Magick::Image using: const MagickCore::Image* MagickCoreImage = MagickImage.constImage(); Then, as I initially wanted, I was able to use the two functions ResetImagePropertyIterator ...

Thanks again for your very quick answer Fred!

Thanks for your answer Fred. Unfortunately, I need to find a way to make this work using Magick++ only. ImageMagick C API could be an option too but it's less desirable. The only metadata I was able to write to file so far is a subset of the dpx tags, as specified here: http://www.imagemagick.org ...

Hi, In 2010, magick wrote: Magick++ updates a few EXIF attributes internally such as the image resolution and orientation. Currently it does not support user specified EXIF attributes. Is there any progress in having Magick++ writing Exif (or XMP or IPTC) metadata to file? Thanks for your help, Julie

Hi again, Since I'm suspecting that those two images (Magick::Image and MagickCore::Image) are two different things and that it's probably impossible to call ResetImagePropertyIterator() on a Magick::Image, here's another question... Is it possible, using Magick++, to iterate through or to get a ...

Hi, I figured I was using the wrong namespace. The following is compiling: const MagickCore::Image* image; MagickCore::ResetImagePropertyIterator( image ); Now I would need to call the function with the image parameter being a Magick:Image instead of a MagickCore::Image. Thanks in advance for any ...

Hi, I'm trying to use the two functions ResetImagePropertyIterator() and GetNextImageProperty() (that can be found in include/magick/property.h). I'm using VisualStudio and I have: #include <Magick++.h> #include <magick/property.h> at the top of my file. First, I tried: ResetImagePropertyIterator ...

Awesome!

Thank you for letting me know so quickly.

Do you have an idea of when (approximately, of course) this next version will be available?

Thanks!

Julie
