Image Filters: Colourful Processors

Overview

Today has been my best day in terms of Likes and Views on my website. I have come to the obvious conclusion that most people are more interested in seeing pretty pictures than they are in reading articles on source code.

That’s ok, I also like pretty pictures SmileI have uploaded some more eye candy. The images were created by modifying an image originally authored by Konstantin Lanzet. The original image file is licensed under the Attribution-Share Alike 3.0 Unported license, and can be downloaded from .

As a point of interest, all of the filters implemented were done through software I had written from scratch. Most of the application source code have been discussed in various articles and published here on my . All applications and related source code are of course open source.

This is what the original image looks like:

After applying various colour filters and a bit of copy and paste the result:

Image Filters: Light bulb Patterns

Overview

I’ve started development on pattern based colour filtering today. The software still needs some work, but so far the results are starting to look quite promising.

At this point I’ve only implemented variable sized checkerboard patterns. The idea being to divide an image into a number of squares and then to only include alternating squares when applying various colour filters.

Keep in mind all of the images shown below were generated from the same source image. The original image reflects a fairly standard image of a clear glass bayonet light bulb.

RSS Buttons: Alternative Colours

I’ve been experimenting with Colour Filter Image manipulation lately. As an example showcasing some of the possibilities I created several images based on the standard orange RSS feed icon.

The following section provides a thumbnails preview of the images I created. Please note that all images have the size dimension of 2000×2000 pixels. I’ve opted to provide high resolution images to accommodate better results should images be edited further. It is not recommended using high resolution images directly due to larger file sizes when compared to typically used lower resolution images. Reducing image resolution is a fairly straight forward task easily achieved using most image editing software.

Images are provided under the . You are free to download, modify and redistribute the images.

Create and download PDF documents on Wikipedia.org

Overview

I consider Wikipedia.org as one of my favourite and definitely most used online resources. Recently I unintentionally discovered a really useful feature exposed by Wikipedia: Compiling ebooks from one or several Wikipedia articles. Being able to neatly package Wikipedia content for offline reference use can prove to be very useful in certain scenarios.

The Wikipedia Book Creator

The process of compiling and managing ebook formatted Wikipedia content is the responsibility of the Wikipedia Book Creator. The first step in using the Book Creator would to make sure you’ve enable Book Creator.

Wikipedia’s navigation pane on the left-hand side of the screen provides a link to enable Book Creator, located under the Print/Export option:

WikipediaBookCreator

After clicking the Create a Book link, the page that loads next provides a button to start the Book Creator:

WikipediaBookCreatorEnable

In addition on this page you will find instructions relating to how to make use of the Book Creator feature. More in depth information can be found on the Book Creator Help page.

Once you’ve enabled the Book Creator you can continue browsing Wikipedia as per normal, with the exception of specifying which article pages should be added to your book.

Adding Article pages

You will notice that at the top of each Wikipedia article page you are now presented with additional links allowing you to interact with the Book Creator. As you browse through articles on Wikipedia you only have to click the link titled Add this page to your book.

BookCreator_AddArticlePages

Compiling and Downloading your Wikipedia eBook

When you decide that you have included enough article content in your book you can start reviewing your book by clicking the Show Book link located towards the top of the page.

When reviewing your book you can remove Wikipedia articles you no longer want to include in the final eBook, additionally you can specify the book’s title and subtitle.

BookCreator_Review

The final step required to create your book is to specify the eBook format you prefer and then to click download.

BookCreator_Download

Do note that Wikipedia also provides a service allowing users to order a printed copy of the eBook being generated.

In the steps illustrated above I created a PDF format eBook referencing Microsoft’s Wikipedia page. You can download the generated eBook here.
