Subject: [PATCH] Makefile: Reduce file size of figure generated from ibmqx2-labeled.svg
The .svg file contains a high-resolution scanned bitmap image and
results in a large .pdf file of more than 6.3MB. It is about 46
percent of the size of final perfbook.pdf.
By adding a recipe to convert such .svg files to lower resolution
.png files, perfbook.pdf can be made much smaller.
Size of perfbook.pdf (can vary depending on LaTeX / other tool config):
before: 13.7 MB
after: 7.7 MB
DPI=200 is chosen for .png file output. Resulting Figure 17.16 looks
good enough. That said, we should restrict the use of .png in
exceptional cases. Otherwise, we would lose the merit of vector
graphics.
While we are here, remove the comment in target "neatfreak".
There have been make rules to take care of generating necessary
PDF files for quite some time.
NOTE: You need to remove future/ibmqx2-labeled.pdf before doing
"make" to see the effect of this change. Alternatively,
"make clean" removes both .png and .pdf files generated by the
added recipe along with several other files.
The high resolution figure can be restored by overriding the
definition of SVG_LARGE_BITMAP by a make option such as:
"make clean; make SVG_LARGE_BITMAP=".
