New version of LazMapViewer

[wp]

After a long time, a new version of LazMapViewer has been released for OPM.

Considerable progress has been made by contributions of forum user "alpine" who dramatically improved drawing performance and usability on non-Windows widgetsets. He also added a layer system so that multiple layers of (semitransparent) layers can be overlayed, and markers and tracks and areas can be added even at design-time (https://wiki.lazarus.freepascal.org/LazMapViewer#Map_Overlays).

Forum user "EkkehardDomning" added a plugin manager which makes it very easy to extend the functionality of the mapviewer by addons. Now we have addons for drawing a magnification scale, a degree grid, popup hints for markers, dragging markers, adding copyright notes, etc. All available plugins are listed on the updated wiki page https://wiki.lazarus.freepascal.org/LazMapViewer#Available_plugins. There is also a new wiki page covering the topic of how to write your own plugins (https://wiki.freepascal.org/LazMapViewer-Plugins).

Thank you for your efforts.

I tried to install LazMapviewer with a freshly installed Pascal Lazarus 4.8 on Windows 10 64-bit.
The different parts are downloaded, and the installation stops after the synapse part.
There is no recompilation of the IDE.

On the other hand I did the installations from the downloaded .lpk files and it seems to work.

I still have to test/adapt my old programs using LazMapviewer.

Thank you anyway.

Hi again,
I tested my program using LazMapviewer on Windows 10 64 Bits, Lazarus 4.8, and with a minor change, it's working.

Thank you again.

Did you install Synapse first? But anyway, the Synapse DownloadEngine normally is not needed, it is included only for users having Synapse in their project already. Otherwise, in Windows the internal windows routines are called, and in the other OSs the FPHttpClient is used.

What did you have to change? LazMapViewer should work out of the box.

Hi,

Just the map provider OpenStreet Mapnick to OpenStreet Normal.

Also tested on Linux Mint 22.1, same problem for installation but using the downloaded .lpk, it's O.K.

Thank you again.
