base: Introducing utility for writing raw data in png format
Originally it was possible to use a Bitmap writer class for dumping a framebuffer snapshot in a .bmp file. This patch enables you to choose another format. In particular it implements the writing of PNG Images using libpng library. The latter has to be already installed in your machine, otherwise gem5 will default to the Bitmap format. This configurable writer has been introduced in the VNC frame dumping mechanism, which is storing changed frame buffers from the VNC server Change-Id: Id7e5763c82235f1ce90381c8486b85a7cce734ce Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-on: https://gem5-review.googlesource.com/5181 Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>
