Unable to detect the alpha channel in a PNG image file (without loading the entire image in memory)

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...

Re: Writing tiff files with depth different than 8 and 16

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...

Writing tiff files with depth different than 8 and 16

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 o...

Re: Magick++ does not write EXIF data?

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! :)

Re: Magick++ does not write EXIF data?

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...

Re: Magick++ does not write EXIF data?

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!

Re: Problems with functions ResetImagePropertyIterator() and GetNextImageProperty()

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...

Re: Magick++ does not write EXIF data?

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/sc...

Re: Magick++ does not write EXIF data?

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

Re: Problems with functions ResetImagePropertyIterator() and GetNextImageProperty()

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 lis...

Re: Problems with functions ResetImagePropertyIterator() and GetNextImageProperty()

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 ad...

Problems with functions ResetImagePropertyIterator() and GetNextImageProperty()

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( i...

Re: conversion to RLE coded tga fails

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!
