Re: [svg-developers] Re: different look in ie6 and vb6. Why?

2004-12-08 Thread Mario Vernari 

Hi Maciek,
sorry to be in late for the answer...
It is not hard to build a web server to connect a browser. In fact you will 
use a normal browser (IE, Mozilla or whatever else can support the Adobe or 
SVG with XMLHTTP capabilities).

I personally decided to embed the IE control in a VB6 form and that ActiveX 
calls the Adobe's viewer (as IE itself).

Once you've called the "base" SVG document, the script contained should poll 
the web server every (let's say) some second.
Basically, the plugin asks/posts for "news" to the web server and it waits for 
the answer.

In my app I have used a different port than the (default) 80, just to avoid 
collisions with "real" web servers (IIS, Apache, etc).

Just drop me your email, I'll try to collect a simple app to show how it 
works.
In case you are in a hurry, take a look for some web server sample in 
http://www.planet-source-code.com

Have a nice day.
Mario

using djikstra.ure help would very much be appreaciate. 

Oh,and how do i pass the value-points selected from SVG to javascript

Hi Richard,

Thanks for the link, that is similiar to what I'll need to do. The 
only difference is that when the user clicks on the zoom in button, 
it stays pressed in and the user clicks on the area that will be 
zoomed into.

I was hoping to find a way get the magnifying glass cursor to 
appear, but I don't see a way to do it. There isn't a method to turn 
on the zoom or pan functions in the viewer like the Ctrl and Alt 
keys do. I was wondering if there was a way to simulate or trick the 
viewer that the Ctrl or Alt key was pressed. 

I tried sending different combinations of the keypress, keydown, 
mouseover, and focus events with the key code and character code to 
the viewer, without success of course.

Is the javascript external of the SVG or internal?

Yes seems like our provider is too stupid to fix the security hole

[svg-developers] How to expose & manipulate external SVG objects

2004-12-08 Thread Sherm 


I'm trying to modify an existing SVG/javascript app to be as modular 
and small as possible. I'm breaking a large SVG file (600k +) into 
smaller modules so that only the necessary parts are loaded, greatly 
reducing the initial loading time.

I'm using getURL(), parseXML() and appendChild() functions to import 
SVG objects. I can easily get the external object to appear, but I 
can't figure out how to expose the object in the DOM to manipulate 
fill and stroke attributes, or to transform the object in any way.

Is this possible with these functions, or are they currently limited 
to just display-only, like an ?

thanks in advance for your assistance.

RE: [svg-developers] XMl 2 SVG

2004-12-08 Thread Rick Bullotta 

Fear not, nothing heinous.  I share the same concerns you do.  I think it is
ridiculous some of the patents that have been applied for (and granted). It
bugs me to no end.  I've seen things like the SCO suit which is a last-ditch
desperation move by a dying company, and the many ridiculous dot-com
lawsuits, and even some in our industry (manufacturing) around what was
supposed to be an "open standard".

 

In fact, I've always been pretty willing to share what we've been doing as
far as the SVG animation part of it.  Just that no one seemed to be
interested ;).

 

The "unique" stuff we're doing is more in our connectivity and data binding
approach to manufacturing and ERP data sources.

 

I'm all for opening up and sharing what we're doing around SVG and
visualization.  We gain significant value from open source efforts and have
contributed (code, testing, and $$$) to many of them.

 

Things like W3C-driven standards efforts have always seemed like a bit of a
closed club.  Irregardless, I'd be all for a "non-standard" but valuable
open source effort around this type of effort.

 

Anyone interested?

Subject: RE: [svg-developers] XMl 2 SVG




We built our own, for a very specific purpose (manufacturing and executive
dashboards).  Corel was doing some stuff, as was Beatware (though not
SVG-specific, if I recall).

We explored XSL as one approach and found it to get "in the way". Instead,
created a (patent applied for) model by which we have:

1) The "raw" SVG (a SVG drawing of some sort)
2) The "properties" of the SVG drawing that are to be mappable/configurable
3) The "mappings" from the abstract "properties" to specific SVG
elements/attributes
4) The "raw" data (one or more XML documents containing data)
5) The "expressions" which populate those properties from the data

The key reason for the "properties" abstraction was to expose top-level
"typed" properties for the visualization object.  For example, if we created
some type of dial gauge, the "properties" might include:

- Background color
- Needle color
- Minimum range
- Maximum range
- Value
- Label
- NumberFormat

Then, through a visual GUI, these abstract properties were bound, using
fairly rich expressions (a bit more than ECMA script) to the appropriate SVG
elements/attributes.

Lastly, through another visual GUI, these "generic" display objects could
have their properties bound (once again, via expressions) to data.  The
other "special sauce" in this GUI was hiding the ugliness of Xpath from the
user and allowing them to drag-and-drop from XML documents to the property
mapper/expression editor.

>From a technology perspective, there's nothing special needed other than an
XML parser (.NET or Java).  The actual rendering can be done server-side
(via a web service) or client-side (via a helper applet and the Adobe
viewer).  To accomplish the outbound server-side rendering to an image, we
have created separate server-side components that leverage
SharpVectorGraphics on the .NET platform and Batik in Java environments.

Hope that gives you some idea of what it possible!

well is 1D19C STROKE-3 + ID19D STROKE-3 prall useful? ie the feta font
glyph is prall but unicode uses the combination of 1D19C STROKE-3 +
ID19D STROKE-3.

when I want a prall in lilyxml I must call 1D19C STROKE-3 + ID19D
STROKE-3 and it will give me the feta prall.

but I can't give prall an encoding of 1D19C STROKE-3 + ID19D STROKE-3
can I?

Or maybe I will use feta but add the missing partial glyphs that unicode
uses to create expressions with...

maybe I will just write to the developers of lilypond.

I would use Feta and provide a mapping from characters to
glyphs that you feel is useful.  An SVG font can have
ligatures (multiple characters that map to a single glyph).
Since I can't find any good description of the design of
the feta font I can't really tell if this will be useful to
you.

I suspect that the text generated will be a bit complex.
Something like "a2a"  where "a" produces the note head and
"2a" produces the 1/2 note "a" stem or something.  You can't have
"a2" (or "2a" produce a "2a" ligature glyph and an "a" glyph).
You could have a "2a" ligature that includes the head and the stem.

Re: [svg-developers] Re: music and fonts and graphics

2004-12-08 Thread Aaron 

Hmn I doubt there was a unicode music font when they started and they
were creating a special purpose type one font.


I don't have to use feta I guess.

Anyone know of a unicode font that has all the symbols?

I could I guess make my own font if I have to.

but I am not sure how to use the unicode encoding, it seems that in
unicode I must combine glyphs to acheive many normal glyphs for music.

this seems to add a lot of complication to the issue of displaying
music.

I am now most confused.
Thanks
Aaron

If you mean, can you make an SVG glyph that combines several other
glyphs, I don't know how to do so without combining the paths
manually. I don't know how to make a compound glyph. Perhaps ChrisL
can make a recommendation.

Yup. I don't see an easy way to reconcile Feta with the Unicode
charset. It sure would be nice if the Lilypond creators had considered
that when designing the fonts.

I don't know enough about private codepage definition to make a
recommendation on how to proceed when the approved codepages don't
suit your purpose.

RE: [svg-developers] XMl 2 SVG

2004-12-08 Thread Rick Bullotta 

We built our own, for a very specific purpose (manufacturing and executive
dashboards).  Corel was doing some stuff, as was Beatware (though not
SVG-specific, if I recall).

We explored XSL as one approach and found it to get "in the way". Instead,
created a (patent applied for) model by which we have:

1) The "raw" SVG (a SVG drawing of some sort)
2) The "properties" of the SVG drawing that are to be mappable/configurable
3) The "mappings" from the abstract "properties" to specific SVG
elements/attributes
4) The "raw" data (one or more XML documents containing data)
5) The "expressions" which populate those properties from the data 

The key reason for the "properties" abstraction was to expose top-level
"typed" properties for the visualization object.  For example, if we created
some type of dial gauge, the "properties" might include:

- Background color
- Needle color
- Minimum range
- Maximum range
- Value
- Label
- NumberFormat

Then, through a visual GUI, these abstract properties were bound, using
fairly rich expressions (a bit more than ECMA script) to the appropriate SVG
elements/attributes.

Lastly, through another visual GUI, these "generic" display objects could
have their properties bound (once again, via expressions) to data.  The
other "special sauce" in this GUI was hiding the ugliness of Xpath from the
user and allowing them to drag-and-drop from XML documents to the property
mapper/expression editor.

>From a technology perspective, there's nothing special needed other than an
XML parser (.NET or Java).  The actual rendering can be done server-side
(via a web service) or client-side (via a helper applet and the Adobe
viewer).  To accomplish the outbound server-side rendering to an image, we
have created separate server-side components that leverage
SharpVectorGraphics on the .NET platform and Batik in Java environments.

Hope that gives you some idea of what it possible!

The combine pieces together or they use symbols from elsewhere in the

Which means I have now no idea how I will get unicode =feta

so can I do this?

this is crazy the feta font has so many glyphs that the unicode encoding
doesn't have. Very frustrating. 
Does this mean I am stuck and can't use the feta font now? I gather
other fonts also have the same problem.

RE: [svg-developers] Simulate Ctrl & Alt Key Press to Zoom and Pan

2004-12-08 Thread Richard Gnyla 

Hi

 

A javascript file does all the hard work by controlling the SVG file, also
there is a toggle button to control whether the user wants the zoom / pan
animated or not, with hidden fields in the html to determine the control.

 

Although this is specific to us, If you want me to send over the files for
you to hack to suit your application then let me know.

 

This wont work in Mozilla yet as the DOM is different, but we aim to resolve
this in the future.

Once the page loads up you can zoom and pan, but it is all written in

Is there a way to simulate the Ctrl and Alt key press to zoom or pan?

We're using ASV3 and I need to make a tool bar that has a zoom in, 
zoom out, and pan function. For example, clicking on the magnifying 
glass button in the tool bar will do the same as pressing the Ctrl

Any help or ideas would be greatly appreciated.

Re: [svg-developers] Re: Expanding and collapsing sections of bargrap hs using SVG - Can it be done?

2004-12-08 Thread Jérôme Tricand de la Goutte 

Hi Patricia,

I was planing to implement a tree view. So here is how I see it :
 - I would use a personnal namespace, let say "tree"
 - I would create my structure in my svg file as, for example

   The text of the parent
   
   
   The text of the child1
   
   
   
   The text of the child2
   
   
   The text of the underchild1
   
   
   
   
- at the onload event of  my svg, I would run a function "initTree()" 
converting this structure in standard SVG element, with events and 
personnal attributes as

 
 The text of the parent
 
 
 
 The text of the child1
 
  
  
 
 The text of the child2
 

 
 The text of the 
underchild1
 
  
  

tree:index represent the number of  tabulation, ie the level in 
hierarchy of an element.
tree:width is the width of the bounding box of an element with its childs
tree:height if the height of the bounding bos of an element with its childs.

Those two values are used by the function showhidechild to calculate the 
new translate of any nextsibling element when you show one element.
For example, say you have the folowing structure:
1shown
   2shown
  3unshown
  4shown
   5shown
  6shown
  7shown
8   shown
   9 shown
  10   shonw

and you want to show 3. You will have to translate 4, 5 and 8, ie the 
nextsibling element of 3, 2 and 1, ie the nextsibing element of every 
parent of the element you want to show and itself.
You will have to add to the translate value of those elements (4, 5 and 
8) the height of the element 3, then display 3

If you want to hide one element, you will have to remove the height of 3 
of the translate value 4, 5 and 8.

That said, you can imagine what initTree should do :
read the tree:elements
creatre the structure using  elements
compute the height of any element
hide all the child elements at first

And showhidechild() should do
get the element that needs to be expanded or reduce (A)
get the size of A
add or remove this size to the translate of any nextsibing of any 
parent of A
show or hide the childs of A

And this should work.


If you want to add or remove an child, don't forget to compute the new 
size of any parent of this

As you see, this shoud work for any type of child (text, graph, ... )


I hope it helps you.
but I would be pleased to have you comments, if it works and so...
