    <p>FWIW I just released (Apache 2, hosted on GitHub) a simple image-scaling library for Java called <a href="https://github.com/thebuzzmedia/imgscalr" rel="noreferrer">imgscalr</a> (available on <a href="http://mvnrepository.com/artifact/org.imgscalr/imgscalr-lib" rel="noreferrer">Maven central</a>).</p> <p>The library implements a few different approaches to image-scaling (including Chris Campbell's incremental approach with a few minor enhancements) and will either pick the most optimal approach for you if you ask it to, or give you the fastest or best looking (if you ask for that).</p> <p>Usage is dead-simple, just a bunch of static methods. The simplest use-case is:</p> <pre><code>BufferedImage scaledImage = Scalr.resize(myImage, 200); </code></pre> <p>All operations maintain the image's original proportions, so in this case you are asking imgscalr to resize your image within a bounds of 200 pixels wide and 200 pixels tall and by default it will automatically select the best-looking and fastest approach for that since it wasn't specified.</p> <p>I realize on the outset this looks like self-promotion (it is), but I spent my fair share of time googling this exact same subject and kept coming up with different results/approaches/thoughts/suggestions and decided to sit down and write a simple implementation that would address that 80-85% use-cases where you have an image and probably want a thumbnail for it -- either as fast as possible or as good-looking as possible (for those that have tried, you'll notice doing a Graphics.drawImage even with BICUBIC interpolation to a small enough image, it still looks like garbage).</p>

    1. CORiyad, I liked using Scalr. I am curious to know, how did you end up picking an API with all static methods? I had written a similar api which was closer to a builder. Like `new ImageScaler(img).resizeTo(...).rotate(...).cropTo(...).toOutputBuffer()`. I like your way too and I think it is simpler.

    2. COAmir, the builder pattern works wonderfully for these types of libraries as well, I just happened to go with the static-method approach because I thought it was a *hair* easier to follow for new users and the usage-pattern I expected from imgscalr (originally only single resize methods) didn't benefit from having an instance holding state (The builder instance). So I saved on the object instantiation and went with the static methods. I have taken a strong stance against object-creation inside of imgscalr in every place I can avoid it. Both approaches work great though.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
