Convert Dicom Image to JPG

Asked 2022-Mar-01 at 07:06

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 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

RMagick Draw Image using Array RGB

Asked 2021-Oct-30 at 20:10

I have an array of RGB values for individual pixels of a digital result that has analyzed an image. The array represents rows of individual pixels, which make up the image. The resulting image shows me what groups of pixels qualify as being "hot spots".

I'm using RMagick in Ruby and I'm wanting to build this result image from the arrays of pixels that I have. I'm not clear as to how I can import that array as the visual pixel colours. An example:

From your ruby -v, I see that you are in an Intel x86 Mac, but the gem that your trying to build (nokogiri-1.11.3-arm64-darwin) is for new Mac ARM M1 chips. If this is the cause, it means your are using precompiled gems.

Try uninstalling the gem, specify that you don't want to use precompiled gems, and reinstall.

Rails 6 image upload to digitalocean spaces

Asked 2021-Mar-12 at 18:45

I have a blog that uploads banner and thumbnail images. I originally had it set to upload to the local directory using the carrierwave gem and I wanted to try to use digitalocean spaces since the app is deployed to the digitalocean app platform. I am able to get it working on localhost:3000 but when I deploy it to digitalocean it keeps reverting back to a previous deployment saying that a health check failed but not real errors.

I decided to deploy it to heroku since I am able to get actual errors. Here is the current error I get from heroku:

It seems like the server can't access to the content of the credentials.yml. This file is encrypted and Rails use the master key store in the master.key file to read it. So given that the master.key is not checked into version control, you need to provide it manually on the server. Please check this article https://medium.com/cedarcode/rails-5-2-credentials-9b3324851336

This section :

Deploying master key

When you move your code to a server, you need to make sure that your config/credentials.yml.enc file can be decrypted. That means that somehow you’ll need to provide Rails with your master key, given that it is not checked into version control.

There are two ways of doing that:

Option 1: Place the config/master.key file in the server. You’ll normally want to symlink this file to a shared folder in the server filesystem. Again, do not version your config/master.key file.

Option 2: create a RAILS_MASTER_KEY ENV variable. Rails will detect it and use it as your master key, e.g. in heroku: heroku config:set RAILS_MASTER_KEY=.

You should be able to use any of those indistinctly.

If you are using RBENV as you ruby manager, you can store your env var doing this :

You will create .rbenv-vars in your project folder, not your rails project folder but the folder in which is your project folder, the parent folder if you want.

After that you put your env var inside the file like this:

DATABASE_PWD=*****

no quotes, no space too before ou after the "="

According to the rmagick docs, imagelist does not support urls for converting images. You need to use open-uri gem and URI.open method to open the PDF and pass it to the imagelist.

Ruby on Rails 4.1.8 Gem::LoadError for mysql2 gem

Asked 2020-Jun-22 at 18:38

I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8.

Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10.

I could then install mysql2 with by passing the correct libraries to it: gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include

Everything works locally, all good.

I think I see what's going on. In your Dockerfile, change your DB_URL from: mysql:// to mysql2://

You are loading the mysql2 gem, but indicating to ActiveRecord that you want to use a connection via the mysql gem.

To display the image, the browser only need a URL to the image. If you don't want to store the image on your HDD, you can encode the image into a data URL.
