White square with masks and use

Hello,

We found a similar issue as before (white rectangle image) with masks. My hunch would be the special node <use [...]></use> but I'm not sure.

I'm attaching the non-working SVG and an updated version of the same SVG that works.

wrong processing

Hi there!
I've got a svg that can't be rendered correctly.
It's pretty simple, could you take a quick glance at it?
Thx

testgrad.svg.zip

Specifying DPI doesn't always work

Hi again :)

I am trying to specify another DPI than 96 (tried 960 for all these example files) to svgren::render, but the resulting image seems to become the same anyways. I use parameters 0 for width and height. Here is a test file (the same snake picture I have submitted before)
test.zip

Here is another file that behaves differently: The size of the image changes with DPI change, but the actual rendering is in the upper left corner and still the same size.
test2.zip

I do have some files on which the DPI change seems to work, such as this:
test3.zip

Add build instructions

Hi! I can't figure out how to build it from sources under Linux. AFAIU, you are using your own build system, which is not very useful.

Is the drawing result GPU hardware accelerated?

?

tiger.svg not rendering correctly

Hello, I was able to render camera.svg and other 3 simple svgs correctly using the example on tests/render/main.cpp but tiger.svg is failing to render properly:

Here's my result when rendering the file camera.svg:

And here's my result when rendering the file tiger.svg:

I use the exact same code for both, the only thing that I changed was the name of the file. I wonder if this is just happening to me, or if you also are seeing this issue too?

Initial white or black transparent surface makes a difference

In my case I render SVG images which are not fully trancparent in some parts. These images are draw in my mfc application onto other images/backgrounds.
I found ot that it makes a difference if I fill the background with 0x00000000 or 0x00FFFFFF.
I got the best results with a transparent grey background of 0x00AFAFAF.
It would help me a lot to have the filling colour as parameter (with default argument) of the renderer method.
For now I have modified the original source to fix my Problem:

	for(auto& c : ret){
// #ifdef M_SVGREN_WHITE_BACKGROUND
// 		c = 0xffffffff;
// #else
// 		c = 0;
// #endif
		c = 0x00AFAFAF;
	}

This would also help to get rid of the M_SVGREN_WHITE_BACKGROUND define.

update to svgdom 0.3.4

While svgdom 0.3.4 has support for 'enable-background' property and some additional filter elements too, it would be nice if svgren could use them.
In the attached image you can see at least one problem spot.

Render bugs

Hi there!
Still enjoying this excellent library )
But it's time to notice that our stylish sport car has some significant render artifacts on the hood and bumpers.
I suppose they appear due to a bug, because as far as I can remember, about a month ago the car had no those problems. Certainly, it had other ones but the specular spots on the hood were a bit more soft. They had no such sharp edges.
Hope you can fix it easily.

Masked images are not rendered correctly

I have an SVG that looks like this:

<svg xmlns="http://www.w3.org/2000/svg" width="57.12901" height="57.53997" viewBox="0 0 57.12901 57.53997">
    <defs>
        <mask id="mask">
            <circle cy="37.45" cx="36.972" r="28.563" fill="#ffffff" transform="translate(-8.40599 -8.47303)"/>
            <path d="M28.616 28.17h.8c5.4 0 6.84-2.8 6.96-4.92h4.6v28.4h-5.6V32.09h-6.76v-3.92z" fill="#000000" transform="translate(-8.40599 -8.47303)"/>
        </mask>
    </defs>

    <rect width="100%" height="100%" mask="url(#mask)"/>
</svg>

but once it renders, I only get a black rectangle? It seems like the mask is ignored completely.

CAIRO_STATUS_NO_MEMORY on pretty simple svg

Hi there!
I have bumped into svg that cannot be processed.
It's unlikely that there is no memory it looks like a bug.
Hope you could sort this out as usual easily )
granddad.zip

OSX crashes, no longer linked to cairo

left a comment on the commit I think is causing this:

Some paths elements don't display in rendered image

It's me again :) I hope you're not getting too tired of me :O

One of the SVGs I posted in my previous issue has some very small path objects that don't appear on the rendering. When rendered from Inkscape it looks like this:

This is the rendering from svgren:

I tried to scale up the rendering (see my previous issue ;) to see if the detail would show up, but no luck.

Here is the SVG file again:
test2.zip

Here's an example of one of the paths that doesn't appear:
<path style="fill:none;fill-opacity:1;fill-rule:evenodd;stroke:#000000;stroke-width:1.00000003pt;stroke-linecap:butt;stroke-linejoin:miter;stroke-opacity:1" d="m 149.375,231.737 c 7.1603,-2.352 14.6432,-5.3254 21.875,-6.875 l -21.875,6.875 c 7.1603,-2.352 14.6432,-5.3254 21.875,-6.875" id="path731" />

Implement gaussian blur effect

Library is unusable in debug mode

After Update to latest version of svgren I permanently get an assertion in svgdom while loading-
Simple example:
menue-new.zip

Everything rendererd fine in my last libraries but I wanted to try out your last performance optimisations.
In release Version everything looks fine and it seems to be a lot faster too.

Is there a way to disable these assertions?

Linker failure VS 2017

I'm trying to use this library in VS 2017 and am getting the following linker error in a very plain Win32 application. Are there any solution or project settings I'm missing?

SVG Animation support

I just know if supports svg animation and export from specific frame. This is a cool feature.

request for UWP build

Hi Ivan!
Building process for windows desktop platform is pretty simple (thanks for nuget packages)
It would be nice if you could provide us ability to build this amazing library for Universal Windows Platform too. Or any advise how to compile it for UWP with minimal efforts.
Many thanks.

compile svgren with static runtime

Hi there!
I try to compile svgren.lib (or dll) for Win32 with statically linked runtime (/MT flag instead of /MD ).
VSVS 2015 give me a bunch of linking error (see bellow)
Steps to reproduce:

1. Update to the latest svgren (v. 0.4.43)
2. Open msvs_solution.sln
3. Choose v140_Release configuration and x86 platform
4. Right click on libsvgren -> Properties -> C/C++-> Code Generation -> Runtime Library-> Multi-threaded (/MT)
5. Rebuild

There are lot of complains about unresolved externals symbols and mismatch detected:

build.log.txt

Properties -> Reference Packages shows that we have choice between static and dynamic for cairo and pixman libs.

Further investigation shows that in despite of these settings all libs are 'multi-threaded dll' linked (they all contain -MD flag inside, instead of -MT).

Earlier I saw in some previous versions of svgren, pugixml package had two selectable options (static / dynamic)

It would be nice if we could choose what runtime to use too.
(I personally prefer static linking)

Many thanks for your work!

Drawing problem

I have a drawing problem with svgren. The Lines are missing.

This is the output of svgren:

And this is the way it is supposed to look (like firefox renders it):

This is the korosponding SVG file:
interface-ethernet.zip

I hope you can fix this problem.

Sinve the new version transparency is gone

Hi,
I just wanted to update all the libraries to the latest version ....
Transparency seems to be gone ....

I think I need to stay on the "old" version until this is fixed.

After some investigation I thing it is your change: "msvs: define white background macro for debug builds "
In my case I need transparency in DEBUG as well.

Why not just passing the desired background colour as a parameter with default zero?

Different rendering after update

Hi again :)

After updating to the latest version from 0.4.9 the rendering is different.

Here is what the rendering of an SVG lookes like from Inkscape and in version 0.4.9:

This is what it looks like now after updating:

It's the same SVG file I submitted in a previous issue, but here it is again:
test.zip

broken parsing on android

after upgrading to 0.4.38 my android app stopped working.
Small investigation shows that libsvgren cannot read svg files generated on windows platforms (with 0d 0a line breaks)
an example: z_tiger1.zip
I see migration from pugixml to mikroxml.
What's the reason?
Pugixml works correctly with any line styles.
Moreover, simple time measurements show that pugixml is a bit faster on my testing android devices.
It would be nice to provide us ability to switch to another xml parser.

Background shape is missing

Hi,
I haven't had issuses since a quite long time now. Just now I discovered an image where the Background is not drawn. The same image rendered in firefox has the background shape.

Rendered by svgren

Rendered by firefox

I attached the original SVG file.
FW5-24V.zip

It would be great if you could fix this.
I'am using the latest versions of your library on Windows with Visual Studio 2015

renderer doesn't support default fill black

Any black element is not rendered correctly. Comparing two svg files shows that with colour black no style element is exported. The file without style renderes correctly in firefox.

SVG-File with error:
button-add.zip

See screenshot of the compare tool:

svgdom 0.3.6

Hi there!
I've noticed that despite existing svgdom version 0.3.6 you're still using 0.3.3 in your ms vs projects: libsvgren and render_test (see corresponding packages.config for each projects). Is it ok?

VS2015 build problem

First: thank you. A very interesting piece of work.

Second: Is there a stable branch? Loading the existing solution file into VS2015 updated all nuget packages as expected. The build fails with the log below. Any help much appreciated.

Render with Cairo

I'm new to svgren and cairo, following the basic tutorial.

After obtaining std::vector<uint32> by calling svgren::render(...), what should I do next with cairo to render the resulting data with a given cairo_surface_t *?

CMake support

Hi,

Would you, by any chance, have a CMake script to build your library? Or planned to make one eventually?

Thanks!

crash during render

Hi there!
I've updated to 0.4.42 because of performance issue on our nice sport car.
Greats improvements! Car is rendered about 20 times faster!!!
Then I tried other (previously hard-rendered) svgs and alas... some of them crash
machupicchu.zip
.
Could you please locate and fix a problem?
Thanks in advance!

style "visibility:hidden" of GElement not working as intended, only style "opacity:0" does

I created a svg with a <g> working as a library, so I can <use> its elements multiple times elsewhere. But hiding that library did not work using style="visibility:hidden".
I came across https://stackoverflow.com/a/20328945/3410351, so I tried style="opacity:0" and it actually hides the children of the GElement. However, those SVGs with <g style="visibility:hidden"> are not rendered correctly by SvgRen.

<style> element not supported

The <style> element is not supported yet. Support for <style> will require implementing CSS selector logic.

can't process svg

Hi there!
Thanks for the great lib.
I'd like to use it in further but unfortunately had encountered a problem.
I've got a svg that can't be properly processed (see attachment).
I realize that that svg is pretty complicated but still want to get it rendered.
Rendering it on my PC takes about a minute and gives a memory corruption as a result.
(google chrome spits it out in a few seconds)
Could you please locate the problem and fix it?

Problems with rotation transform on groups

When a group has a rotation transform, the rotation seems to be applied wrong. Here is the actual image:

And here is the rendering:

Here is the SVG file used:

Thanks again for making this, it is great to have a good open-source SVG renderer!

<use> element not supported

The <use> element is not being rendered properly. I though that use was supported since the code allows element references by id. I tried to render the following example without success:

<svg width="80" height="80" xmlns="http://www.w3.org/2000/svg">
  <style>
    .classA {
      fill: red;
    }
  </style> 
  <defs>
    <g id="Port">
      <circle style="fill: inherit;" r="10"/>
    </g>
  </defs>
 
  <text y="15">black</text>
  <use x="50" y="10" href="#Port" />
  <text y="35">red</text>
  <use x="50" y="30" href="#Port" class="classA"/>
  <text y="55">blue</text>
  <use x="50" y="50" href="#Port" style="fill: blue;"/>
</svg>

It should look something like this:

This is what I get instead:

SVG Images with viewbox in percent are not rendered

Some SVG Images have a viewbox in percent and they don't get rendered at all. See attached example.
I have a simple solution for this:

m_pImage = svgdom::load(papki::FSFile((LPCSTR)a_rFilename));
if (m_pImage != nullptr)
{
	if (m_pImage->width.isPercent() )
	{
		int lViewboxWidth = m_pImage->viewBox[2] - m_pImage->viewBox[0];
		int lViewboxHeight = m_pImage->viewBox[3] - m_pImage->viewBox[1];

		if ((lViewboxWidth > 0) && (lViewboxHeight > 0))
		{
			m_pImage->width.value = lViewboxWidth;
			m_pImage->width.unit = svgdom::Length::Unit_e::PX;
			m_pImage->height.value = lViewboxHeight;
			m_pImage->height.unit = svgdom::Length::Unit_e::PX;
		}
	}
	std::vector<std::uint32_t> lImage = svgren::render(*m_pImage, m_OrigWidth, m_OrigHeight);
}

In my opinion it would make sense to integrate this into the renderer method.

I don't need swap Red and Blue

In my case I create a mfc Bitmap with transparency from the rendered bytes. I found ot that I need to swap red and blue to get the correct colors. When I looked at the source code of the renderer method I found out that swap of red and blue is done in the renderer method as well.
In my case I wouldn't need the internal swap of red & blu at all. Now I need to to do it a second time to revert the internal swap.
Perhaps an aditional parameter of the renderer method could save the double swap times.

remove redundant linkage against libpapki

Currently there is a direct linkage to libpapki because of Cygwin environment. Need to fix packaging of all libs for cygwin, because dll's should go to /bin and .a and .dll.a should go to /lib in cygwin.
Actually, this might be an improvement for prorab even.

See https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/4/html/Using_ld_the_GNU_Linker/win32.html for info.

lib can not render svg without explicitly set size

A simple svg from wiki can not be rendered by svgren, while others tools spit it out easily.
A brief investigation shows that that svg doesn't contain explicit definition of size.
I do realize that we should know the size of memory buffer before render and nevertheless want to find a way to render such simple svg by default. Can you take a short glance on this and produce an idea?

Crash on android less than 5.0

Hi there!
I'm trying to get it working on android 4.0.4 and have troubles with unimplemented 'rand', 'srand' and some other functions.
The problem looks similar to this:
https://stackoverflow.com/questions/27338318/cannot-load-library-reloc-library1285-cannot-locate-rand
It works fine on devices with api >= 21 and crashes on older ones.

When I change platformVersion to 19 in build.gradle, I get an error: undefined reference to 'rand'..
Is it possible to use SvgRen on android with api less than 21?

Thanks in advance for any ideas and thoughts )

Error in renderer gradientGetFx

Hi, thanks for this library.

I found an issue with a svg file that causes crash in gradientGetFx method.

It seems "caster.radial" is not null so it passes the if-test but then radial points to deallocated memory so it crashes.

I cannot share the svg-file here but I can email it if you want.

Strange rendering of path element

I am adding SVG support to a little hobby game I have. I made a test picture with Inkscape and tried to load it. Here are the results:

The body of the character in the in-game screenshot is rendered as a triangle. Here is the SVG file used:
test.zip

I it matters I am using 64 bit Windows 7, the latest svgren from GIT, libsvgdom.0.2.25 and cairo_static.1.15.4.1.

And also, a big thank you for making this library.

Nuget for svgren on VS2012 results in compilation errors

I am new to all of these things and wanted to get my hands on SVG rendering and displaying.
I have VS2012 and tried to get svgren and its dependencies using VS2012 Manage Nuget Packages.
When I tried to include the files as described in the example, I run into all sort of issues. Would really appreciate if i can be provided with any pointers...
