Hello,

I've started to make a 2D gis editor.
At this moment I'm using Upp 2007.1 with MinGW on Windows 2000.

The question is what is good starting point implementing the on screen (and printer) render classes.

I think i could do it myself, translating geometry world coordinates to screen coordinates, implementing zoom etc. and only using the U++ Draw class.

Can i use the geom package?

I searched forum, but there is no documentation or examples describing the geom package.
Even on SVN I can't found working version of Geom package.

I found Gertwin questions about Geom, and seems like he have same problems like me.
So what is current status of Geom package and shal I use it in my project ?

Plese help ! Embarassed

Geom, our nemesis Smile

Well, the problem with Geom is that it contains a lot of tremedously useful code, but it would definitely need some polishing.

Well, I guess, maybe just copy what you find useful into your code. As soon as "final" Geom is available, removing it from your code should not be hard.

Thank you for fast reply Mirek !

At this moment I'll continue digging into Geom package.
How I can be useful for 'final' Geom ?
I can upload somewhere working Geom, when I finish.
(May be here in forum ?)

By the way, I have some additional extras for Upp, that can be useful for other Upp users.

Where to upload thease pieses of code ?

SORRY for my bad english ! Embarassed

In this last time I have learned the basic of the use of Ultimate++, I really liked a lot in comparison with others. Now I am interested in making a GIS. I have seen for myself and also here in the forum that the package GEOM has difficulties, however, I have also read of people that have been able to work with the package GEOM (PlotterCtrl, ...), with files of vectorial images as *. shp and others. I don't know as they have made it, if they have modified, added or removed files. They could please help me.
Thank you.

Hello Mirex, and tried Painter, is very good. But it seems not to have certain characteristics which have to handle elements Geom GIS, it will later? Or should I only have these particular characteristics Geom. Thank you.

Hm, like what? (I am not that much into GIS, but I believe there is not much GIS stuff in Geom).

Do you mean a control that can paint sdo_geometry structs?

Sorry if I am wrong. I am referring to what Rylek mentioned:

"...
geom - various 2D and 3D analytic geometry calculations, linear equation set solver, Delaunay triangulator, generic polygon rasterizer

geom/Coords - utilities for geographic coordinate transform calculations; several coordinate systems have already been implemented, unfortunately (for evident reasons) mostly systems used in the middle Europe.

geom/Draw - linear & bilinear image warping (imgtran), floating-point based drawing tools (plotter), generic patterned line drawing (pathDraw)

geom/Ctrl - Ctrl-related stuff, most important is PlotterCtrl which is a zoomable view to a physical floating-point-based world
..."

Painter basically provides better equivalent of geom/Draw.
