Re: [Wxart2d-users_dev] a2dRect limit to boundary

[klaas.holwerda <ng...@kl...>]

Hi Shaul,

Not sure I understand, do you want to stay the rectangle within another rectangle area?
There is nothing implemented like that.
But as you can study in the rectangle tool, you can do whatever you want there, same for the dragtool.
Just copy the code of the tool in question, and restrict it in in the way you need, tuned to your 
application.
Next as all other tools push it (your own version) on the tool controller stack, or whatever method 
you are using to start tools.
  It is of course some work, hope it answers your question.

Regards,

Klaas

[Wxart2d-users_dev] a2dRect limit to boundary

[Shaul S. <sha...@gm...>]

Hello,
I am using the a2dDrawRectangleTool. Is there a way to restrict the move of
an a2dRect on dragging to a certain boundary?
Thank you,

Re: [Wxart2d-users_dev] Image display is opposite

[Shaul S. <sha...@gm...>]

Hi Klass,

I tried the zoom example.
I now understand why it was opposite because of the Yaxis.
My colleague Trey was able to use the library on Mingw 64-bit.

Thanks,
Shaul

Hi Shaul,

Are you using a a2dMemDcDrawer?
Can you run the zoom example?
The question is maybe more, what is right or wrong??
Clearly in part down here, I decided once, in the case of AggDrawer, that I wanted it to go along 
with the Yaxis, so not always up.
I think my reasoning of doing it like this, is that when Yaxis changes, everything you see should be 
upside down, including images.

Currently it seems when Yaxis is negative, the image is drawn as in wxWidgets itself, meaning Up.

void a2dAggDrawer::DrawImage(  const wxImage& image, double x, double y, double width, double 
height, wxUint8 Opacity )
{
     if ( m_disableDrawing )
         return;
     int imagew = image.GetWidth();
     int imageh = image.GetHeight();

     agg::trans_affine mtxi;
     mtxi *= agg::trans_affine_scaling( width / imagew, height / imageh );
     mtxi *= agg::trans_affine_translation( x - width / 2, y - height / 2 );
     // pictures always upwards
     //if ( m_yaxis )
     //    mtxi *= agg::trans_affine_reflection_unit( 1, 0 );

But you are right, there were some heavy changes in the drawing context area, so it did change 
somewhere.
Do not know what is best, or maybe it should even become an option.

What is your opinion?
Regards,

Klaas

[Wxart2d-users_dev] Image display is opposite

[Shaul S. <sha...@gm...>]

Hi,

In the current version the Image display is opposite.
in r963the image display was correct.

a2dImage *Image;
a2dCanvas* Canvas;
Image->GetImage().LoadFile( _T("c:\\test.bmp")  );
Image->Mirror();//not needed in version r963
Canvas->GetDrawing()->Append(Image);

[Wxart2d-users_dev] Building wxart2D with wxwidgets 3.2 on Ubuntu and mac

[Zoltan T. <zo...@gm...>]

Dear wxart2D developers,

I recently tried to build wxart2D on an ubuntu 22.04 and a m2 Mac (Sonoma) box and got the same error from cmake. I am using gtk3 toolkit on Ubuntu and osx-cocoa-unicode-3.2 (the output of wx-config —selected-config). However in both cases I get a cmake error connected to not finding the right wxwidgets libraries. The error is this: 

**************************************************************************************************************************************************
wxArt2D/packages/wxart2d/share/wxwidgets/FindwxWidgets.cmake(122): 
--debug=no;--static=yes;--unicode=yes;--universal=no;--toolkit=osx_cocoa-unicode;--version=3.2 failed. 
The default configuration found with: /usr/local/bin/wx-config --selected_config 
is the following: osx_cocoa-unicode-3.2

CMake Error at share/wxwidgets/FindwxWidgets.cmake:1377 (MESSAGE):
  wxWidgets required, please specify it's location.
Call Stack (most recent call first):
  CMakeLists.txt:119 (find_package)
**************************************************************************************************************************************************
The very same error message appears at the wxdocview module as well and also on ubuntu with gtk3-unicode. I played around with the FindwxWidgets.cmake script but no success. 

Is there a way to bypass this? Is it possible to use wxart2D with wxwidetgs 3.2.2? Is it possible to build it on an m2 Mac?

Thanks!

[klaas.holwerda <ng...@kl...>]

Hi,

I am not the one using it, but I believe that using the free version of visual studio, you may only 
create freeware opensource, or something like that. At least commercial issues.
So one license of VC will do, I think. I develop on VC since it is close to perfect in debugging, 
although I use Linux all the time. So via virtual box at home.
Anyway, I use at home the free version, and one linux gcc.
MIngw, is like the Unix/Linux setup, but even of it compiles on Ubuntu, that still might mean 
problems on mingw.
I currently do not have the time, to dive into this.
I suggest to first get it going on Ubuntu, or redhat, if you succeed with that, mingw is next.
Hope it helps,

Klaas

[Wxart2d-users_dev] wxArt2D Information

[Paris R. <rp...@es...>]

Dear all,

I'm interested in your library wxArt2D
I had a brief look to its website and source code ...

I'd like to use the library in a project of mine written using wxWidgets v3.2.0
Would you be so kind to reply this message answering the questions below ?

It would be very useful for me, thank you in advance.

1) Is the library maintained ?
2) Could I use Inkskape as editor for SVG file and then load such files into my 
application to show it on a wxWindow ?
3) Is there a way to change dynamically a colour or other stuff, from original 
InkSkape objects, using wxArt2D features ?

Thank you for your help
kind regards

Re: [Wxart2d-users_dev] 回复: a2dCanvas Display Rupture When Dragging with Mouse Right Button Down

Hi,

I put your code in the simple sample in wxart2d, compiled it, and drag shapes using Ctrl + Left 
Mouse Down.
Seems fine to me what I see. So for the moment I can't reproduce what you see.

This one line is not needed, but that is wxWidgets basics ( it Destroys its child windows starting 
at top window, so it has a tree to find them, this line ruins it ):
     delete m_frame;

Hi,klass

Using wxart2d in my little display program, now the program can run 
basically, thanks for your help.

Just now, I found a question again and don't know how to set to avoid 
this problem.

The frame contains a2dCanvas and displaying figure is good, zoom in and 
zoom out also is well.

But when dragging with mouse right button down, some big figure shape 
will appear rupture(Sorry I don't know how to describe it) which like 
this below. Small figure shape will not appear this.

Do not add the below code snippet and replace a2dAggDrawer with
