ImageOptimizer | A Visual Studio extension | Image Editing library

I have been using ImageResizer (https://imageresizing.net/) to resize Images. I wrote a console app that was resizing images in a specified directory on my disk.

The console app was working fine, but then i added my project to a ASP.NET MVC app, and it doesnt work. I didnt just move the code, i moved the whole project and just call a start method i created that is the same as my previous main from console app. I did install resizer from NuGet in my WebApp.

When my code gets to the point where i resize images, i get an error "Request is not available in this context" This is the part where i try to resize my image:

In my Laravel 5/vuejs 2.6 I upload an image with the vue-upload-component and am sending a requested image blob I try to save it with the controller code like :

I've created a context menu with a couple of menu items like so:

I am trying to compress image(usually around 5-30) quality / size with Magick.NET library, and I cant really understand how can I use ImageOptimizer class and call LosslessCompress() method using stream.

• Do I need to use FileStream or MemoryStream?
• Do I need to save / create a temp file on server for each image and then proceed with the compression flow? (Performance?)
• Anything else?

Simple Code example:

I installed composer require spatie/image-optimizer, but when I run the example below the I had two problems: 1- The class could not be found by calling it by using (use). So I solved it by using include.

2- After solving the first problem, the code works fine but the resultant image is the same image with no optimization.

this is my first question here so please don't be to harsh on me :) Anyway, let's get right to it:

For an application I need to convert a PDF file to an Image file (Specific format doesn't matter but preferably png or jpg). To get this done, I try to use ImageMagick but when I try to convert anything, it will throw an error. Now after some research I came to the conclusion I needed to have Ghostscript installed, which I tried to get from the NuGet package manager integrated in Visual Studio 2017. Anyway, when I try to install said package, it throws the following error:

Severity Code Description Project File Line Suppression >State Error Failed to add reference to 'gsdll32'. Please make sure that the file is accessible, and that it is a valid >assembly or COM component.

I'm trying to accomplish this using Visual Studio 2017 with C#. The API's I am using are: +Magick.NET-Q16-AnyCPU V7.11.1 +GhostScriptSharp V1.3.1.4 +Ghostscript V9.2.0 (Throws error)

In case it is required to understand what I am trying, here is the code that I am trying to compile:

I can't edit some records in Rails Admin after do a multiple files upload using Carrierwave.

I guess that did the correct config, when I upload the files everything goes well, but if I try edit after save the record that error happens:

I have created the following 4 model and its table structure for my project:

Media.php To upload images in app

Medias table structure

id | path

Example of path:uploads/images/media/food-1542110154.jpg

Post.php Create post

Posts table structure

id | title | content

FeaturedImage.php Featured image for post

Posts table structure

id | post_id| path

Post model and FeaturedImage model are in a one-to-one relationship

UploadImage.php To resize the uploaded image and move it to another directory. This model doesn't have migration and controller

Code snippet from PostsController.php to create the post

I am trying to migrate from Rails 4.2 to Rails 5.0 (running on ruby 2.3) (see plan here https://stackoverflow.com/a/38443616/7374136)

The plan is to:

1. Update the rails gem and all dependencies.
2. Run tests (covering almost our whole code base) for depreciations and fix them.
3. Run rake rails:update to update Rails
4. Adapt the configuration, application classes, breaking changes, ...

Nevertheless, I am blocked at the first step already, updating the rails gem and dependencies. gem 'rails', '4.2.5' -> gem 'rails', '~> 5.0' running: bundle update rails.

I faced multiple dependencies issues, which I fixed by looking for any dependencies that ultimately require rails to be less than 5, and see if those can be updated. Running:
