New version of Mapparium released this time for all Amiga systems. (Also for m68k Amiga, take care it needs a GFX Cards and a FPU to work).
Changes:
Check out the Mapparium page.
I optimized Mapparium drawing a little bit for 68k Amiga at least in UAE it’s working now with reasonable speed (even faster than the native OS4 I tried). On a real Amiga of course will be much slower. I do not have a Graphics card (which is needed for this program). Maybe later I find one to test.
Implemented GPX reading and writing, really very easy. Tested with some of my cycle routes (I cuted the start away for the screenshot). It also saves the waypoints and tracks into a default.gpx to load at next start, its the easiest way to start. At the moment I draw a little rectangle at every track point and connect them with a line. Sadly it seems to be not possible to draw a thick line with the standard methods, the PenWidth and PenHeight in RastPort are ignored. so I guess this point approach works best for recorded tracks. For planed routes with little points its hard to see. Maybe I write an own line drawing routine, with Bresenham it should be possible to make.

Besides I increased the speed dramatically on drawing, on Amiga 68k its much faster now, even usable and resizing on MorphOS with less problems and much faster, it does not recalculate the complete image on every resize step, but only draws the image.
Playing around with OpenStreetMap. Of course one can use a browser (I guess it is working) but I want play around with images and network
Of course on a Next Generation Amiga it makes more fun:
But also on 68k Amiga it work 😉
New Version for the Virtual Lazarus crosscompiler, some crashes with mouse events (OnClick, OnMove, OnEnter, OnLeave), Redrawing and resizing problems and of course the biggest change adding support AmigaOS4 (PowerPC). I removed some not needed files and installations, so the download is much smaller this time.
Changes in short:
Download the new Virtual Lazarus crosscompile setup (1.2 Gb)
I am thinking how to make an online updater, in principle not so difficult with a script, svn update from repository, recompile/install all compilers/crosscompilers, update lazarus repository, recompile and install lazarus, done.
As promised, I cared about drawing with alpha channel on m68k Amiga. Little bit background. When I make a StretchDraw() the raw data is scaled directly in pascal (to keep the alpha channel) via a nearest neighbor routine. And exactly there I need to touch every pixel to scale it, of course a good position to also care about the alpha channel. For speed optimization the special cases 0 and 255 alpha channel are handled separately. And its not so slow as I thought, so I let it inside.

EdiSyn on AmigaOS4
Working on the image drawing in LCL, not only for OS4 but for all, the problem is that it needs (semi-)transparent drawing. I started with Picasso96 for OS4 but it seems it still has no Alpha channel support. But luckily it also supports the cybergraphics compatible layer with the alpha channel support. So I changed everything in LCL back to cybergraphics, which is even much better, because now it’s the same for all platforms.
On this occasion the problem on MorphOS came to light. I always had the problem that at MorphOS the images are not shown. I thought it is a problem with resources but now it became clear, it’s the drawing the globalalpha value was too small.
Sadly the cybergraphics on classic AmigaOS does not support this Alphachannel, thats the reason the image has the black border in the screenshot. Maybe one could try to make a simple Alpha (0/1) by hand, which will be very slow I guess.
Besides I found a big Event problem. Got this as bug report already, it was just a not initialized variable. A little bit more testing and I will make a release and also create a Virtual Lazarus again with all 4 platforms :-).

The AmigaOS4 LCL worked somehow but it did not draw anything on the LCL drawing procedure. Added some debug output and it seems everything works as expected. Finally I got it to work. So now the ColorIt game also work, maybe someone want to try.

I hacked some more library units for AmigaOS needed for the LCL. and finally at least it compiled, I had to deactivate als CyberGraphics things, at least I did not find the corresponding things in the official SDK, so many graphic things are missing.
The biggest problems in the LCL came from my special code for Amiga m68k and (again) different behavior of MUI on AmigaOS4 which resulted in crashes on totally valid Values.
Nevertheless the first LCL program works on a AmigaOS 4 computer.
Added some more units to OS4 freepascal: MUI and networking and created a release archive which will be created as nightly (like the other platforms). You can find them on my nightly folder.
