Hi,
the following sample application consumes more and more memory. Am I
doing something wrong or is this a memory leak in reading svg files? I
tried it with GM 1.1.4 and the current snapshot. The example svg file is
pasted below the code sample.
regards,
Achim

int _tmain(int argc, _TCHAR* argv[])
{
std::fstream source("demo.xml");
std::string data;
std::copy(
std::istreambuf_iterator<char>(source),
std::istreambuf_iterator<char>(),
std::back_inserter(data)
);
Magick::Image image;
for (int i=0 ; i < 10000 ; ++i) {
Magick::Blob blob(data.c_str(), data.size());
image.magick("SVG");
image.read(blob);
}
return 0;
}
