Description
Redmine 4.0.4 using RMagick was fine.
However, Redmine 4.1.0 using MiniMagick does not work.
prodution.log of Redmine 4.1.0 is this:
Started GET "/redmine/projects/some_project/issues/gantt.png?..." for (IP) at (date)
Processing by GanttsController#show as PNG
Parameters: {...}
Current user: admin (id=1)
Completed 500 Internal Server Error in 290ms (ActiveRecord: 63.0ms)
Errno::E2BIG (Arg list too long - convert):

app/controllers/gantts_controller.rb:44:in `block (2 levels) in show'
app/controllers/gantts_controller.rb:42:in `show'
On Windows, the ImageMagick's "convert" command length is too long, and then error occurred.
I want to shorten the command length or split the command if Redmine keeps using Minimagick.
And there should be some exception code as below:

For some reason, I have to keep using Redmine on Windows...
Updated by Anonymous about 4 years ago
To work on Windows, divided the MiniMagick "convert" block.
This patch can display up to about 200 issues.
However, the subjects() and lines() functions create "convert" commands internally, so these could't be divided.

Changed to split MiniMagick's "convert" command on Windows only.
To do so, changed the "convert" object (gc) to an instance variable (@gc), and added an @minimagick_command_max instance variable for the command splitting.

hello， taca tadocolo
"@gc.size('%dx%d' % [subject_width + g_width + 1, height])" build error was occurred.
how to fix it？
