Download and Installation

Development version

Use an svn client to download the current trunk version from svn://svn.code.sf.net/p/lazarus-ccr/svn/components/lazmapviewer. Alternatively download the zipped snapshot from https://sourceforge.net/p/lazarus-ccr/svn/HEAD/tree/components/lazmapviewer/ and unzip it to some folder.

Release version

Occasionally, release versions are made available via the Online Package Manager for easy one-click-installation directly from Lazarus.

Installation

In Lazarus, go to "Package" > "Open Package File .lpk". Navigate to the folder with the LazMapViewer sources, and select lazmapviewerpkg.lkp. Click "Compile", then "Use" > "Install". This will rebuild the IDE (it may take some time). When the process is finished the IDE will restart, and you'll find the MapViewer in the palette Misc.

There are optional, supporting packages to extend the basic functionality. They must be installed in the same way, after lazmapviewerpkg.lpk.
