wrap_rsvg

wrap_rsvg is an Eiffel binding of Librsv C API using WrapC tool.

This is librsvg - A small library to render Scalable Vector Graphics (SVG), associated with the GNOME Project. It renders SVG files to Cairo surfaces. Cairo is the 2D, antialiased drawing library that GNOME uses to draw things to the screen or to generate output for printing.

Requirements

• WrapC tool.
• Librsvg C API

Download and Install

Linux

Here I will describe the installation for Ubuntu check the librsvg documentation to know how to install it in other Platforms.

We are using version 2.40.20

Installing dependencies

apt-get install -y gcc make rustc cargo \
automake autoconf libtool gettext itstool \
libgdk-pixbuf2.0-dev libgirepository1.0-dev \
gtk-doc-tools git \
libxml2-dev libcairo2-dev libpango1.0-dev libcroco3-dev

Basic compilation instructions

If you are compiling a tarball:

./configure
make
make install

See the INSTALL file for details on options you can pass to the configure script to select where to install the compiled library.

If you are compiling from a git checkout:

./autogen.sh
make
make install

Workaround LInux

If you got the error gdk-pixbuf-query-loaders not found in path

sudo ln -s /usr/lib/*/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders /usr/local/bin/gdk-pixbuf-query-loaders

Now try again to compile and install the library.

Windows

Using vckpg

	vckpg install librsvg:x64-windows

Copy the .lib files rsvg-2.40.lib and cairo.lib to $ECF_CONFIG_PATH/C/lib. Be sure to have the dlls in the PATH before running the example.

How to compile the C library glue code.

Before to use the examples you will need to compile the C glue code, go to

library/generated_wrapper/c/src

and run

finish_freezing --library

It will copy the C lib eif_librsvg.a to $ECF_CONFIG_PATH/C/spec/$(ISE_PLATFORM)/lib/ or eif_librsvg.lib to $ECF_CONFIG_PATH/C/spec/$ISE_C_COMPILER/$ISE_PLATFORM/lib
