renderengine dll crash

SvgWindow window = (SvgWindow)svgPictureBox.Window;

svgPictureBox.LoadXml("<svg
xmlns='http://www.w3.org/2000/svg'/>");

I'm doing this piece of code on my form constructor,
and i have the following windows form initialization:

this.svgPictureBox.AutoSize = true;

this.svgPictureBox.Dock =
System.Windows.Forms.DockStyle.Fill;

this.svgPictureBox.Location = new
System.Drawing.Point(0, 0);

this.svgPictureBox.Name = "svgPictureBox";

this.svgPictureBox.Size = new System.Drawing.Size(624,
381);

this.svgPictureBox.Surface = null;

this.svgPictureBox.TabIndex = 25;

when i minimize the window, a nullpointerexception is
thrown at GraphicsNode.BeforeRender(ISvgRenderer
renderer) overriden method. More exactly, at the
following line:

graphicsContainer = graphics.BeginContainer();

Vertically transposed text not appearing correctly

Anonymous — Mon, 09 Jan 2006 00:31:58 -0000

I've got an SVG export from the Nevron Charting tool.
It looks fine when I view it in the Adobe SVG Viewer,
but when I export the SVG using SVG#, using the
following code:

______
SharpVectors.Renderer.Gdi.GdiRenderer renderer
= new SharpVectors.Renderer.Gdi.GdiRenderer();

SharpVectors.Dom.Svg.SvgWindow window = new
SharpVectors.Dom.Svg.SvgWindow(4000, 1000, renderer);

SharpVectors.Dom.Svg.SvgDocument document =
new SharpVectors.Dom.Svg.SvgDocument(window);
document.Load
(this.textBox1.Text);

Bitmap bitmap =
renderer.Render(document);
bitmap.Save
("c:\\temp\\out.png",
System.Drawing.Imaging.ImageFormat.Png);
______

The process succeeds, but the text is not shown
correctly. I'll attach the SVG and outputted PNG files
for reference.

This is happening on version 0.4 alpha of the code.

When I use svg.Load(@"C:\xyz.svg" I get the following error

When I use svg.Load(@"C:\xyz.svg" I get the following

Vertical gradients?

Anonymous — Mon, 05 Jan 2004 23:57:04 -0000

With build 3.1, I cannot get a gradient to render
vertically, only horizontally.

Yet, when I use the Online Demo, it renders correctly.
Is the online demo build the 3.1 build?

Here's the SVG I used:

<?xml version="1.0" ?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1
Basic//EN"

"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11-
basic.dtd">

height="100%" version="1.1" baseProfile="basic">
<defs>
<linearGradient id="bggradient"
x1="0%" y1="0%" x2="0%"

y2="100%">
<stop offset="0%"

style="stop-color:rgb(255,255,0);stop-opacity:1"/>
<stop offset="100%"

style="stop-color:rgb(255,0,0);stop-opacity:1"/>
</linearGradient>
</defs>
<rect width="100%" height="100%"
style="fill:url(#bggradient)"/>
</svg>

Local SVG file handle not closed after loading

Anonymous — Mon, 05 Jan 2004 23:55:03 -0000

Because the XmlReader is not closed after the
SvgDocument.LoadAndFire method is ran, the file is
locked, making any changes to the SVG file impossible
after the file has been loaded. The following fixes the
bug:

in SvgDocument.cs, line 446:
reader.Close();
#endif//ENABLE_LOAD_EVENTS
}

Change to:

#endif//ENABLE_LOAD_EVENTS
reader.Close();
}

uri(#<id>) reference fails for svg loaded from a strin

Mike Graham — Thu, 09 Oct 2003 12:04:06 -0000

First off, this project is elegant, well organized, and very
useful !!

Bug description: when a svg document is loaded from a
string, the uri(#<id>) references generate an exception
when rendering.

Workaround: write the string to a temporary file and
load from the file.

Code to reproduce:
-----------------------------------------
GdiRenderer svgRenderer = new GdiRenderer();
SvgWindow window = new SvgWindow(75, 25,
svgRenderer);
SvgDocument doc = new SvgDocument(window);

doc.LoadXml("<svg xmlns='http://www.w3.org/2000/svg'
xmlns:xlink='http://www.w3.org/1999/xlink'
version='1.0.1' x='0' y='0' width='150' height='25'
viewBox='0 0 150 25'><defs><marker id='triangle1'
viewBox='0 0 10 10' refX='0' refY='5'
markerUnits='strokeWidth' markerWidth='4'
markerHeight='3'><path d='M 0 0 L 10 5 L 0 10
z' /></marker><marker id='square' viewBox='0 0 10 10'
refX='5' refY='5' markerUnits='strokeWidth'
markerWidth='4' markerHeight='4'><rect x='0' y='0'
width='10' height='10' /></marker><marker id='circle'
viewBox='0 0 10 10' refX='5' refY='5'
markerUnits='strokeWidth' markerWidth='4'
markerHeight='4'><circle cx='5' cy='5'
r='5' /></marker></defs><polyline points='7.5 12.5 142.5
12.5' stroke='green' stroke-width='3' stroke-
dasharray='10,5' marker-end='url(#square)'
fill='none' /></svg>");

Bitmap b = svgRenderer.Render(doc);

Exception in x-Attribute of rect-Element

Anonymous — Wed, 13 Aug 2003 08:35:26 -0000

The x-Attribute (I think also the y-Attribute) of the rect-
element isn't supported.

Even this small svg doesn't work:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG
20001102//EN"
"http://www.w3.org/TR/2000/CR-SVG-
20001102/DTD/svg-20001102.dtd">
<svg width="1cm" height="1cm">
<rect x="10" y="10" width="10" height="10"/>
</svg>

So SVG# is totaly unusable for me :-(

creating images with no viewer

Anonymous — Sat, 12 Apr 2003 16:59:58 -0000

2 problems.

I'm trying to create a bitmap by passing in an svg
document and svg# seems to truncate the results. I
also cannot find a way to do this with without specifying
a size to pass in. Without a viewer I'm just making
something up, and it seems to affect how the image is
created (too small and the image disappears, too big
and your machine crashes).

Here is the code fragment I'm using, adapted from your
viewer code:

SvgWindow domWindow = new SvgWindow
(1000, 1000);
domWindow.Src
= "file:///c:/tmp/batikLogoNoDtd.svg";
Bitmap bmp = (new GdiRenderer
(domWindow, Color.White)).Render();

I've atttached the svg file that does not display correctly
using this code. It happens even if the size is increased
to 1500@1500.

Can you please indicate how to use svg# as a bitmap
engine - i.e. passing a uri &/or dom element without a
view to enforce a viewport size (i.e. use the image's
natural size). This is a feature in Batik The code
fragment there is:

fileStream = new FileOutputStream(file);
JPEGTranscoder t = new JPEGTranscoder();
t.addTranscodingHint
(JPEGTranscoder.KEY_QUALITY, new Float(.8));
TranscoderOutput output = new
TranscoderOutput(fileStream);
t.transcode(new TranscoderInput(uri), output);
-- or --
t.transcode(new TranscoderInput(doc),
output);

Hopefully there is a code fragment I can use to work
around this. Thanks for all the great work!
