I need to convert a .msg file to an jpeg image. Can we do it using ImageMagick ?
I tried to run the below command,
magick mail.msg mail.jpeg
but it gives an error :
magick: no decode delegate for this image format `MSG' # error/constitute.c/ReadImage/512.
I need .msg to be converted into an image.
Can you please suggest if that is possible.
Thanks,
Abha

I am trying to convert a dicom file to JPG which I would then use to show as thumbnail for the dicom file. I am using the code below to convert the dicom file but When I execute it I get the following error
'write': no encode delegate for this image format `' # error/constitute.c/WriteImage/1272 (Magick::ImageMagickError)
I am using ruby version 2.7.0 and I have installed ImageMagick 7.1.0-4 and the supportive gems. How to solve this error?
require 'dicom'
require 'rmagick'
include DICOM
dcm = DObject.read("sample.dcm")
image = dcm.image(:frame => 5)
image.normalize.write("test.jpeg");
I had to reinstall ImageMagick-7.1.0-26 along with libgdcm-tools on my system and the above mentioned code worked fine. So Imagemagick needs these additional libraries (libjpeg62-dev, libtiff-dev, libpng-dev, libpng12-0 and libgdcm-tools) to work with these image types. I don't know if this is correct or not but that the problem I was facing has been resolved by following this approach. Here are some of the links which helped me in solving this

I am trying to convert base64 of tiff to base64 of png in controller of Ruby on Rails.
But, failed...
my ruby code is
#png_de =Base64.strict_encode64(IO.read('..//test1234.tif', mode: 'rb') )
this code causes not display a png image but a load failed icon in chrome.
I don't know how to fix the above issue
I am using ImageMagick to convert a gif to multiple png data. But I get this error:
convert: improper image header
/misc/lmbraid11/jingl/webscraping/dataset_2018_05_18/image2018_5_4_10_34.gif'
# error/gif.c/ReadGIFImage/1037. convert: no images defined
/misc/lmbraid11/jingl/webscraping/dataset_2018_05_18/image2018_5_4_10_34.png'
# error/convert.c/ConvertImageCommand/3210.
Here is the command:
convert -coalesce /misc/lmbraid11/jingl/webscraping/dataset_2018_05_18/image2018_5_4_10_34.gif /misc/lmbraid11/jingl/webscraping/dataset_2018_05_18/image2018_5_4_10_34.png
The gif file was downloaded from:
[http://www.niederschlagsradar.de/image.ashx?type=regioloop®io=fre][1]
ImageMagick version: Version: ImageMagick 6.8.9-9 Q16 x86_64
Any help will be appreciated.
Problem get solved. It turns out that I did not download the gif file correctly, so the gif file was corrupted.
The syntax should be:
convert image2018_5_4_10_34.gif -coalesce image2018_5_4_10_34.png
In your case, you're specifying the option before files, however it can vary on your IM version.
As per #fmw42 comment:
Note that proper ImageMagick syntax reads the input before the -coalesce. Though ImageMagick 6 is forgiving, ImageMagick 7 is not.
I've been using paperclip for a while, allowing my users to upload svg files to it. The problem here is i would like to convert that svg file into a png (or jpg, it doesnt matter). But i dont know if there is a convert_option value to transform it, or if we can do something about it.
When i run
convert file.svg file.png
in my console, i'm getting
attribute not recognized: n
attribute not recognized: u
attribute not recognized: n
attribute not recognized: u
convert: unable to open image `#': No such file or directory # error/blob.c/OpenBlob/2701.

I'm using macosx with imagemagick
I tested some code which works fine:
C:\root\Dropbox\WWW\TIFF\sandbox 17:17:37,86
$c:\cygwin\bin\convert.exe gallery.tif[0] -thumbnail 300x300^ -format jpg gallery.jpg
But I want to specify full path to image and it is not works - why it is not working?
It is the same image.
c:\root\Dropbox\WWW\TIFF\sandbox\gallery.tif[0] == gallery.tif[0] - why it is not working?
C:\root\Dropbox\WWW\TIFF\sandbox 17:17:59,29
$c:\cygwin\bin\convert.exe c:\root\Dropbox\WWW\TIFF\sandbox\gallery.tif[0] -thumbnail 300x300^ -format jpg gallery.jpg
convert: must specify image size `\root\Dropbox\WWW\TIFF\sandbox\gallery.tif' # error/raw.c/ReadRAWImage/136.
convert: no images defined `gallery.jpg' # error/convert.c/ConvertImageCommand/3210.
You seem to be using Cygwin. Cygwin expects a different way to specify paths. IIRC, you should use something like:
convert.exe /cygdrive/c/root/Dropbox/WWW/TIFF/sandbox/gallery.tif[0] \
-thumbnail 300x300^ -format jpg gallery.jpg
