## Remove the existing version.

    $ brew rm imagemagick

## Edit the formula.

    $ brew edit imagemagick

This will bring it up in an editor; make sure your `$EDITOR` variable is set to your preference (for me: TextMate)

## Change it, save it, try *re*-installing it.

Because most installs use pouring/bottles to install a precompiled binary, you will likely see no change unless you &quot;build from source&quot;:

    $ brew reinstall --build-from-source [...]

You can use `--formula /path/to/imagemagick.rb` as an additional argument to the above command to ensure `brew` is installing the formula that was edited.

If you&#39;re comfortable with git, you may also want to make a branch first, and do your edits in a branch to guard against data loss.

We in our organization are trying to implement a source code quality management tool. SonarQube is one such tool that we have come across, and it&#39;s quite full of features and is phenomenal. We want to compare it with its peers, if there are any, before we actually implement it. 

Are there any good contenders to Sonar&#39;s capabilities and features?

Are there any Quality Management tools other than SonarQube

I installed [ImageMagick][1] via [Homebrew][2].

However, due to a bug I have with my current configuration, I need to adjust the compile flags for the formula and reinstall it.

How can I accomplish this?

How do I modify a Homebrew formula?

I installed <a href="http://en.wikipedia.org/wiki/ImageMagick" target="_blank" rel="noopener noreferrer">ImageMagick</a> via <a href="http://github.com/mxcl/homebrew" target="_blank" rel="noopener noreferrer">Homebrew</a>.

I&#39;ve had numerous problems compiling shared objects that link statically against static libraries. This problem only shows up on x84_64 platforms. When doing the same compilation work on x86_32 I do not have any problems. 

Perhaps this is a OS specific GCC configuration thing, but my research indicates that its how GCC works on x86_64 platforms. Anyhow, I am using gcc 4.4.3 on Ubuntu 10.04 x86_64.

How is the problem fixed ?... Making sure all the static library dependencies are compiled with -fPIC.

**Question 1:** What is the difference between -fpic and -fPIC (apparently -fPIC generates more instructions on x86) ? Why is the later type more relevant in the x86_64 context ? 

**Question 2:** My assumption is that when you link against static code you are hard-wiring the functions into your binary at link time, why does it need the level of indirection the &quot;position independant code&quot; machinery provides ? 

**Question 3:** Now if x86 doesn&#39;t need -fpic / -fPIC to link shared objects against static archives why is it needed in x86_64 ? 

**Question 4:** even if it is needed why isn&#39;t it supplied implicitly ? I thought breaking changes was supposed to be a big no-no

Why does gcc not implicitly supply the -fPIC flag when compiling static libraries on x86_64

In VS2010, I noticed that the &quot;output window&quot; is shown every time we compile the solution, even if we have had close it.

In VS2008, that wasn&#39;t the case. I don&#39;t mind this output window. I prefer looking at the &quot;Error window&quot; only, and only if it is necessary. In VS2008, it was perfect.

How to disable the systematic displaying of the &quot;output window&quot; in VS2010?

Disable displaying of &quot;output window&quot; at each compilation

To get stuck in straight away, a very basic example:

    using System;
    using System.Windows.Forms;
    
    class test
    { 
        static void Main()
        { 
            Console.WriteLine(&quot;test&quot;);
            MessageBox.Show(&quot;test&quot;);
        }
    }

If I compile this with default options (using csc at command line), as expected, it will compile to a console application. Also, because I imported `System.Windows.Forms`, it will also show a message box.

Now, if I use the option `/target:winexe`, which I think is the same as choosing `Windows Application` from within project options, as expected I will only see the Message Box and no console output.

(In fact, the moment it is launched from command line, I can issue the next command before the application has even completed).

So, my question is - I know that you can have &quot;windows&quot;/forms output from a console application, but is there anyway to show the console from a Windows application?

How do I show a console output/window in a forms application?

My web hosting said ImageMagic has been pre-installed on the server. I did a quick search for &quot;ImageMagick&quot; in the output of phpinfo() and I found nothing. I can&#39;t SSH in the server so is there a way in PHP I can verify the installation?

I&#39;m working on a web project that involves a dynamically generated map of the US coloring different states based on a set of data.  

This SVG file gives me a good blank map of the US and is very easy to change the color of each state.  The difficulty is that IE browsers don&#39;t support SVG so in order for me to use the handy syntax the svg offers, I&#39;ll need to convert it to a JPG.  

Ideally, I&#39;d like to do this with only the GD2 library but could also use ImageMagick.  I have absolutely no clue how to do this.  

Any solution that would allow me to dynamically change the colors of states on a map of the US will be considered.  The key is that it is easy to change the colors on the fly and that it is cross browser.  PHP/Apache solutions only, please.

How can I get the difference between two images? I have the original image. Someone has written on an exact duplicate of the original image. Now, I need to compare the original to the written on image and extract just the writing in image format.

Example: I have a picture of a house. Someone took a copy and wrote “Hello!” on the copy. I want to somehow compare the two pictures, remove the house, and be left with an image of the words “Hello!”.

Is this possible with ImageMagick? I know there are ways to get the statistical difference between images, but that is not what I am looking for.

I get the error shown below when attempting to install the rmagick gem. I am on Snowleopard 10.6 using RVM, Ruby 1.9.2-head and Rails 3.05. Responses to similar questions recommended installing ImageMagick, which I successfully did. Other suggested installing the &quot;libmagick9-dev library&quot;, however, I can not figure out how to do this.

I&#39;m a new developer, and any assistance or directions to an existing explanation or resource is greatly appreciated. Thanks!

**UPDATE**
If you&#39;re a Mac/OS X user I would HIGHLY recommend using Homebrew as your package installer/manager. You can find it [HERE][1]. Since originally asking this question I have removed all my prior installs of things like rmagick and imagemagick, and reinstalled them using Homebrew. Super easy with a huge catalog of packages, and updates/uninstalls are a cinch as well!

I am in the step to abandon GD for manipulating image in my website - it is awful.

Everyone saying to use ImageMagick because they are better than GD, but what about ImageMagick vs Gmagick (*Swiss Army knife of image processing*)? 


Zend has a pretty article here http://devzone.zend.com/article/10531 talking about them.

Before I will leave for ImageMagick are there any motivation to use gmagick instead?

(PHP 5.3+)

Edit: What&#39;s wrong with asking which is better between 2 libs? I think it&#39;s a fair question. If someone could explain the good-point of one lib over the other would help me and other people reading this question. Why close such a question??

Edit2: For everyone asking what I need to do: I think it&#39;s oblivious: users uploads images (than can be png/gif/bmp w/e) I need to convert in JPG and then store it in the database, eventually if they are too big I need to resize down them a bit.



Thanks

GD vs ImageMagick vs Gmagick for jpg?

I&#39;m wondering about the preferred way to import packages in a Python application. I have a package structure like this:

    project.app1.models
    project.app1.views
    project.app2.models

`project.app1.views` imports `project.app1.models` and `project.app2.models`. There are two ways to do this that come to mind.

With absolute imports:

    import A.A
    import A.B.B
or with explicit relative imports, as introduced in [Python 2.5 with PEP 328][1]:

    # explicit relative
    from .. import A
    from . import B

What is the most pythonic way to do this?

Absolute vs. explicit relative import of Python module

I&#39;m totally new to Python and I know this question was asked many times, but unfortunately it seems that my situation is a bit different...
I have created a package (or so I think). The catalog tree is like this:

```
mydir
    lib   (__init__.py)
        mod1  (__init__.py, mod11.py)
```

In parenthesis there are files in the catalog. Both `__init__.py` files are zero length.

The file `mydir/lib/mod1/mod11.py` contains the following:

```python
def mod12():
    print &quot;mod12&quot;
```

Now, I run `python`, then `import lib`, which works OK, then `lib.mod11()` or `lib.mod12()`.

Either of the last two gives me the subject error message. Actually `dir(lib)` after Step 2 does not display `mod11` or `mod12` either.
It seems I&#39;m missing something really simple.

(I&#39;m using Python 2.6 in Ubuntu 10.10)

Thank you

I&#39;m trying to setup up MySQL on mac os 10.6 using Homebrew by `brew install mysql 5.1.52`.

Everything goes well and I am also successful with the `mysql_install_db`.  
However when I try to connect to the server using:

    /usr/local/Cellar/mysql/5.1.52/bin/mysqladmin -u root password &#39;mypass&#39;

I get:

I&#39;ve tried to access `mysqladmin or mysql using -u root -proot` as well,  
but it doesn&#39;t work with or without password. 

This is a brand new installation on a brand new machine and as far as I know the new installation must be accessible without a root password. I also tried:

but I also get

Today I installed the `curl` formula via `homebrew`, but after installing it (and re-sourcing the shell) i noticed that :

    % which curl 
    /usr/bin/curl

as a matter of fact, the output of `brew install curl` stated that it was a **keg-only** formula, and that since `curl` was already present in OS X, it didn&#39;t link it into Homebrew prefix, as that could cause unspecified problems.

Then it proceeds stating that

&gt; Generally there are no consequences of this for you
