I'm working in Rails and I'm looking for a library/gem/plugin to generate a graphic from text. Google Maps doesn't allow you to overlay text, only graphics so I'm looking for a back door to overlay text. Suggestions?
Take a look at RMagick.
To draw text using RMagick, you need to use one the text or annotate methods.
You need something like RMagick, though that particular library has been known to leak memory.
libgd can do this, and has bindings for many different languages, including Ruby

Which programming language has best possible image filter and also provide art photo effect and oil paint effect. I've also tried in php-imagick, python-opencv, css, and javascript but they do not exactly provide art effect and oil paint effect.
Prisma app also provide art and oil paint effect but they use neural network and ai technology so how can I use this both technology for my project.
As you have mentioned php-imagick and python-opencv, what you need is a library that provides you the tools you want, the programming language is irrelevant.
Have a look at G'MIC and the image gallery.

My customer wants a pdf reader which has a page curl effect. Also, he wants it to be zoomable as well. I tried using the UIPageViewController but it doesn't support zooming (as far as I know). I also tried using both UIScrollViewController and UIPageViewController by switching between these 2, but it's not so smooth.
Does anyone know any free framework that meets my requirements?
I don't want any content searching, highlighting or anything, just the reader and thumbnail view.
Have a look at this:

Hope this helps...

I found one library two months ago and now I can't remember what was its name.
It does basically this:
I have multiple rectangles with different sizes and I want to add them in this scrollable view.
Does anyone know the name of that library?
Looks like justified View.
Get it here:

This is pinterest-style layout, I suggest looking here:

CocoaControls.com is the very first place for me to search for custom ios controls, I am really recommend it.

Are there any markdown editors that integrate with rails (eg in a gem) and offer live preview?
Checkout markdown.js and showdown. You could rig them up to parse whatever the markdown input is whenever certain events fire (i.e. a user releasing a key when typing in the markdown textarea). I'm not aware of any other embeddable markdown editors with live previews, but it seems it would be easy enough to make one with one of these libraries.
Check out the gem below, its not well documented but seems to work

I have a Rails app that I want to capture a screenshot of a webpage when the user enters a url.
Is it possible to do this in Rails (is there any gem that would do this?)
If not, are there any reliable services that generate live screenshots
I use IMGKit gem for that: https://github.com/csquared/IMGKit

ScreenCap gem which uses PhantomJS under the hood. Grab whole pages or just specific divs, or even exact x y coordinates.
I have used GrabzIt for this. This is quite simple.
