<pre>I am trying to paint a surface (250x160 pixel) derived by reading an SVG file
with rsvg and painting it on that surface on another A8 150x150 pixel image
surface.
This worked up to a few month before the 1.14.0 release (git 337ab1f is ok,
1.14.0 and 1.14.2 not). Now cairo_status after cairo_paint returns
CAIRO_STATUS_NO_MEMORY.
My code is below (full code at
<a href="http://svn.gna.org/viewcvs/vfrnav/trunk/src/metgraph.cc?revision=228&view=markup">http://svn.gna.org/viewcvs/vfrnav/trunk/src/metgraph.cc?revision=228&view=markup</a>).
Cairo::RefPtr<Cairo::ImageSurface>
sfc(Cairo::ImageSurface::create(Cairo::FORMAT_A8, 2 * get_width(), 2 *
get_height()));
Cairo::RefPtr<Cairo::Context> ctx(Cairo::Context::create(sfc));
std::random_shuffle(m_groups.begin(), m_groups.end());
int stride(sfc->get_stride());
const uint8_t *data(sfc->get_data());
double invmaxdensity(1.0 / (255.0 * get_width() * get_height()));
for (groups_t::iterator gi(m_groups.begin()), ge(m_groups.end()); gi != ge;
++gi) {
for (int x = 0; x < 2; ++x)
for (int y = 0; y < 2; ++y) {
ctx->save();
ctx->translate(-x * get_width(), -y * get_height());
ctx->set_source(gi->get_pattern());
ctx->paint();
ctx->restore();
}
342 sfc->flush();</pre>
