Ideally you would create a JIRA issue (and attach the source code to the issue). I will package it up as a page for our user guide ... I am actually super happy you got DirectLayer to work - I have been wanting to add a tutorial on that one for a while. -- Jody -- Jody Garnett On 19 December 2014 at 09:20, Hal Mirsky <hmir...@aseg.com> wrote: Hi Jody, Resending to the list. I have an example program that illustrates how to put a legend on a map that I can share. The program allows the user to open one or more Shapefiles and specify style information for each one. It then creates a legend layer using the feature types and styles. The main program is a modified version of StyleLab. The legend is a subclass of DirectLayer. There are also a few ‘helper’ classes to make this a standalone demo. What’s the next step to post the example?

Some of the legend text was dynamic (e.g. low/high values for each color). A little interesting to figure out the size of rectangles I needed to draw for each legend item. Here's a snippet: private Font titlef = new Font("Ariel", Font.BOLD, 12); private Font itemf = new Font("Ariel", Font.BOLD, 10); Rectangle2D titleLabelRect = titlef.getStringBounds(title, new FontRenderContext(null, RenderingHints.VALUE_TEXT_ANTIALIAS_DEFAULT, RenderingHints.VALUE_FRACTIONALMETRICS_DEFAULT)); Rectangle2D itemLabelRect = itemf.getStringBounds(label, new FontRenderContext(null, RenderingHints.VALUE_TEXT_ANTIALIAS_DEFAULT, RenderingHints.VALUE_FRACTIONALMETRICS_DEFAULT)); // now get the height of the title rectangle and height to use for each legend item: th = (int) titleLabelRect.getHeight(); ih = (int) itemLabelRect.getHeight(); // height of site label. Also used as icon size ...

To style the main part of the map I have followed an example using ColorBrewer and FilterFactory2. I have a Classifier by calling evaluate on a Function from the FilterFactory2. I've have searched and found others asking about this [1], but no answers.
