You mean reaplce:

+int stride = cairo_format_stride_for_width(CAIRO_FORMAT_ARGB32,
m_size.width());

by

+int stride;
+if (cairo_surface_get_type(m_surface) == CAIRO_SURFACE_TYPE_IMAGE)
+    stride = cairo_image_surface_get_stride(m_surface);
+else
+    stride = cairo_format_stride_for_width(CAIRO_FORMAT_ARGB32,
m_size.width());

and expanse it if necessary?
