How to get a Window handle from another app?
Hello,
I would like to get a window handle from another app outside of wxRuby
and convert it into a wxRuby Window handle so that I can use it as the
parent Window for several wxRuby child windows. Basically I want to use
the FRAME_FLOAT_ON_PARENT window style so that my wxRuby windows become
associated with the outside app kind of like toolbars, e.g., they don''t
show up in the

Integrate scruffy graph in rails view?
Hi everybody,
I''m using scruffy to create some graphs, and would like to integrate
them into a regular view (i.e. show them in an <img> tag).
However, I get errors when using img_tag, or the image doesn''t load if
I try saving the graph to disk and then loading them in html.
Generating the graph and linking to it works, however then I only have
the graph open in a new

Image upload problem.
I''ve seen posts of a few people who have this problem, but not a single
response about solving it.
I can''t upload .png files, but .jpg and .gif work fine. When I upload just a
.png, my action gets a StringIO object which breaks when I try to copy the
upload to an absolute location. However, using multiple-field upload, as
long as one of the to-upload files is *not* a .png, all

N file uploads from one post - one File, (N-1) StringIOs

Ruby 1.8.4
Rails 1.1
I have a multipart form that I am posting with a dynamic number of
file_fields that are generated on it, say N.
When I post this form and look at the form params, I see one "File"
object and N-1 "StringIO" objects.
It appears that I should be able to manipulate these the way that I
would like (file-wise), so I think it''s not a

How to integrate Scruff Images
Hi Folks,
since I have scruffy up and running now I´d like to integrate the
desired images on some of my rails views. But neither scruffy nor rails
docs say something about this and I cannot find examples or help on
this. So I hope somebody on this forum has experiences in integrating
scruffy images on rails views.
I find out how to go the easy and obvious way: Export image to a file

How to spec an attachment_fu model
First off, I''m not trying to spec attachment_fu, I know it''s been tested.
But, I added some code to that model that I do need to test. Basically,
I need to somehow fulfill the "uploaded_data" property so I can actually
run my tests(otherwise they fail because of validations). The
"uploaded_data" field is what would grab the multipart data from form.

delay displaying rmagick resizing of uploaded images
Hi,
I am using rmagick to resize a copy of uploaded images and display the
copy as a thumbnail. Once the upload is processed it redirects the user
to a page that should display the thumbnail to the user. The problem is
that the rmagick resize function seems to keep going in the background
after handing the new images url (and control) back to rails, which then
happily renders the page with

Scruffy > MVC architecture?
Hi,
I am a newby in rails...and i have read that scruffy is a great tool to

file_column do download from URL
Is there a simple way of forcing file_column to download file from given

I know:

Scruffy Stacked Bar Chart
Hi-
Trying to do a stacked bar chart, but nothing is rendering when I add
more then 1 bar:
This works:

graph.add :stacked do |stack|
stack.add(:bar, ''Stack1'', [10,10])
end
This doesn''t:

RMagick=bad, ???=good
I know that Zed has made mention of the fact that using RMagick with
mongrel and rails is a bad thing. I''m currently using FlexImage (which
in turn uses RMagick) on my application and really haven''t had too
many problems. We get a restart for memory usage every 8-10 hours on
one mongrel of twelve running, but I''m not sure if that''s an RMagick
issue. Either way,

Using Paperclip::Processor and RMagick to sharpen my thumbnails
Hi, I''m brand new to RMagick (and pretty new to Rails for that
matter!). Right now, site owners are allowed to upload product and
ingredient photos to the website. Everything works great, ingredients
are sized down and proportioned correctly...the problem is that the
resulting images are so blurry! So I''ve been doing some research and
it looks like Paperclip::Processor may be the

there are three that look promising.

Large file support (up and down) for Mongrel 0.13.3
I''ve just checked in changes to improve handling of massive posts and
massive downloads. Generally speaking, Mongrel has been keeping
everything in memory. (Unless you''re using DirHandler and have the
sendfile gem in place.) Now, downloads should be pretty swift even
without the sendfile gem.
HttpResponse#send_file rips out the file streaming support from

Wxruby & RMagick
Hello list,
Has anyone done any work combining WxRuby and RMagick? In Python,
it is possible to convert a PythonMagick image to a Wx::Image and
display it. However, unsurprisingly, the APIs are different in Ruby.
Google didn''t turn up anything. Has anyone on the list worked with
WxRuby and RMagick?
Thanks,
Jacob
