Here you can find some examples of svg for test, which is have difficult path strings.

Add libxml XML access policy

Serve default style values to user as a string, that will be parsed by library, or some other way

Hello. thank you for making good libs. Unfortunately, i have faced a problem when i use it.

My problem is like below :

I tried to use it on VS 2015. and i just added the libs at 'Additional Including folder'

and then i add "#include <svgpp/svgpp.h>" to my cpp files.

When i tried to build it, i could see a lot of errors.

The errors lists pointed to the 123 line at 'enumerate_literal_value.inc' file.

SVGPP_ON_VALUE(small) // Error on Windows may be caused by "small" macro in RpcNdr.h

The source code has already been marked that it will go to error.

How can i do to use it?

I worked with VS2015 and MFC.

According to the SVG 1.1 specification, section 11.6.2, the attributes refX / refY on marker elements are defined as coordinates in the coordinate system after applying viewBox and preserveAspectRatio.
Unfortunately SVG++ resolves the refX / refY value before computing the viewBox, which means that percentage values for refX / refY will be incorrect.

The intersection clip path is archived by the attribute "clip-path" of element "ClipPath" with the use element. But it seems like the attribute "clip-path" in element "ClipPath" isn't supported. The below is the sample file:

<defs>

<clipPath id="clip1">
<polygon id="clip1Shape" points="100,10 40,180 190,60 10,60 160,180 100,10" stroke="blue" />
</clipPath>

<clipPath id="clip2">
<circle id="clip2Shape" cx="100" cy="100" r="65" />
</clipPath>

<!-- Intersection -->
<clipPath id="clipIntersection" clip-path="url(#clip1)">
<use x="0" y="0" width="200" height="200" xlink:href="#clip2Shape" />
</clipPath>

</defs>

<g inkscape:label="Layer 1" inkscape:groupmode="layer" id="layer1">

<rect x="10" y="10" width="180" height="180" fill="red"
clip-path="url(#clipIntersection)" transform="translate(200)" />

</g>

您好，感谢您百忙之中查看该信息。
我在一个MFC工程中使用svgpp，在project中增加 NOMINMAX 。编译之后报错：
1>c:\program files (x86)\windows kits\8.1\include\um\gdiplustypes.h(475): error C3861: “min”: 找不到标识符
不知道怎么解决，请大神帮忙看看，谢谢！

I'm getting an error when compiling the demo on macOS Sierra with Apple LLVM version 8.1.0 (clang-802.0.42), -std=c++11, and Boost 1.64.0:

/src/agg/include/agg_trans_affine.h:313:9: warning: 'register' storage class specifier is deprecated and incompatible with C++1z [-Wdeprecated-register]

struct unsigned_integral_max_value : public mpl::integral_c<UnsignedIntegralChannel,-1> {};

While a strict reading of the SVG1.1 specification requires that transforms in a list are separated by a comma or at least one whitespace character, this test http://www.w3.org/Graphics/SVG/Test/20110816/harness/htmlSVGWeb/coords-transformattr-01-f.html suggests it is not the case, and the specification is erroneous. Indeed, SVG2 (which uses CSS3 transforms) eliminates the requirements, and all major browsers pass the test, unlike svgpp and any app using it.
I suggest amending the grammar used by svgpp to reflect implementation practice.

Get rid of namespace qi= at svgpp namespace

Structures like switch elements or visibility/display attributes require runtime control of further processing

Implement full viewport handling:

• Getting size from root svg element.
• Establishing new viewport.
• Passing viewport size to Length Factory.
• Establishing clipping rect
• ...

Make default error handling more verbose - exceptions must have enough information about errors.

Hello. It is me again.

I have encountered a new problem with gdiplus.

I tried to draw a svgpath.

i could draw it correctly with FillPath method of gdiplus.

But, in case of DrawPath method. There was some artifacts like below.

I painted red rectangles on the artifacts.

Please help me.

Fresh download, trying to compile https://github.com/svgpp/svgpp/blob/master/src/samples/sample01b.cpp

In file "number.hpp" I get an ambiguous call to the second 'ref' on line 108
>> number [ref(value2) = _1, ref(two_values) = true]
and
In file "misc.hpp" I get the ambiguous call to the second 'ref' on line 188
if (qi::parse(it, end, number[ref(value) = _1] >> -(qi::lit('%')[ref(percentage) = true])) && it == end)

In both cases, the collision type is bool and there are two candidate functions, one in "__functional_base.cpp" and one in "reference.hpp". It seems pretty clear that the intended usage is the definition in "reference.hpp".

The problem seems to be Xcode Specific because "__functional_base.cpp" is part of the default xcode C++ toolchain.

Good evening,

With the latest version of Boost (1.63.0), compilation of svgpp fails with the following error when calling document_traversal :

svgpp/parser/grammar/transform.hpp:79:41: erreur : no matching function for call to « bind(<unresolved overloaded function type>, const _r1_type&, const _a_type&, const _b_type&) »
                   >> lit(')') [phx::bind(&transform_grammar::call_translate, _r1, _a, _b)]
                                ~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

My compiler is GCC 6.3.1. I confirmed that the problem does not appear when using Boost 1.62.0.

I found such an error occurs when transform is included in the processed attributes or when shapes_attributes_by_element is used.

Create some policy to pass such information to user code.
Probably further processing of element should also be cancelled.

Now it can be done in XML policy by appending style attribute, but there should be possibility to bypass styles concatenation and subsequent parsing.

I tried to draw svg path data to gdi+ bitmap. I referred to source code in demo for completing it.

In result :

1. It is a svg path of dashcharacter and works well. (It consists of lines)

<path d="M616 440H66V621H616V440Z"/>

2. It is a svg path of alphabet Ocharacter and does not work. (It consists of curves)

<path d="M569 1085q215 0 356.5 -140T1067 547Q1067 234 914 104.5T569 -25Q368 -25 220 108T72 530q0 280 143 417.5T569 1085ZM569 123q154 0 234 114t80 300q0 199 -90.5 300T569 938Q432 938 344 835.5T256 530q0 -202 89.5 -304.5T569 123Z"/>

Case number 2, nothing rendered. The paths which contain Bezier curve seem not to work.

I made Context the same as PathStoragein demo source code.

I have almost spent 5 days to fix it.

Please help me, give me some piece of advice.

Using

cmake -G "Unix Makefiles" -D BOOST_ROOT=/usr/share ../src/samples/
make

I get a lot of these errors:

I have libboost1.54-dev

Thanks for an otherwise good looking SVG library!

Distinguish local and external IRI and pass tag to user code (optional)

The demo application uses load_expected_element() to resolve a marker, and does so in the context of the element making use of it, which means that inherited properties will be resolved using the value available for the element referencing the marker.
This is incorrect, according to section 11.6.2 of the SVG 1.1 specification.

Unfortunately, I found out that parsing a marker element in the normal flow will result in an incorrect viewport handling, as the length factory used to resolve percentages will report bogus results.

I get a segfault when trying to parse files that are more than 1024 chars. 1024 works, 1025 does not.

I've tried using both RapidXML and libxml2 as the XML parser, and the problem occurs in both cases. So, it seems not to be a limit in the parser.

E.g. xml:id attribute is ok

Pass to context indication whether property is from CSS or from presentation attribute along with value. In default Value Events Policy hide this indication.

Create utility that supports color interpolation (properties: ‘color-interpolation’ and ‘color-interpolation-filters’)

Pass icc_color_factory as non-static object, e.g. create rgb colors in place based on previous color profile definitions

Because traversal_detail::is_attribute_id_in_sequence_op references AttributeTag::id instead of AttributeTag::attribute_id, and it does not handle notify_context in the sequence

Tried render Reinel_compass_rose.svg with svgpp_agg_render example.

Error reading file Reinel_compass_rose.svg in element "path": Invalid value of SVG attribute (or property) "d": "M0 h94 m9 h49 m12 h51"

http://upload.wikimedia.org/wikipedia/commons/e/eb/Reinel_compass_rose.svg

If the value of ‘preserveAspectRatio’ on an ‘image’ element starts with 'defer' then the value of the ‘preserveAspectRatio’ attribute on the referenced content if present should be used. If the referenced content lacks a value for ‘preserveAspectRatio’ then the ‘preserveAspectRatio’ attribute should be processed as normal (ignoring 'defer'). For ‘preserveAspectRatio’ on all other elements the 'defer' portion of the attribute is ignored.

Pass 'points' attribute as pair of iterators (boost::range) to user code

Use Spirit abilities to check expectations and report errors in complex attributes (path etc)

Hello,

I am trying to use your library to load some SVG files under QT and post process them.

The compilation is terribly slow.
I mean I only include your main "svgpp/svgpp.hpp" in a single cpp file, where I bind everything into a Qobject, and that file takes something like 3 minutes to compile (Debug mode).
Removing your dependencies, it only takes 2-3 seconds.

Do you have any idea why it would be so slow?
After compilation everything looks fine, and I can execute my code.

Add MSXML COM-interface XML access policy

Check passed policies wherever possible. Mostly for types of items in type sequences

Support the requirement 6.16 User agent style sheet:

svg, symbol, image, marker, pattern, foreignObject { overflow: hidden }

Create some implementations of filter functions

element_iterator::get_child_elements_and_texts() for the msxml policy expects two arguments, but the caller only passes one (and indeed, the function should only receive one, because it declares a variable with the same name)

See http://www.w3.org/TR/2008/REC-CSS2-20080411/ui.html#system-colors

Hello. I get my PC completely frozen when trying to build svgpp.

Saved by REISUB.

Linux Gentoo x86_64

I'm building with -j5 and it's failing, but with -j1 it compiles normaly, but uses about 5GB of RAM per file.
I presume it's templates fault. But it still too much.

PS: also compilation time is just huge. Take me about 30min on 4.2GHz Intel core.

While most of namespaces should be just filtered out by XML policy, some, like xlink (anything else?) are used by SVG++ and must be handled.
How it should be done with namespaces-unaware parsers like RapidXML?
