Have you ever been frustrated by having to differentiate between dozens of similar graphs or figures, and the only memorable difference between them were their unique file names?<\/p>\n

In a recent simulation study, I had exactly that feeling, so I came up with some code to automatically label figures with their file names. Here is how it works:<\/p>\n

For example, please assume three similar graphs with the file names testResults_A.png<\/em>, testResults_B.png<\/em>, and testResults_C.png<\/em>, respectively.<\/p>\n

\"testResults_A\"<\/a>

testResults_A<\/p><\/div>\n

\"testResults_B\"<\/a>

testResults_B<\/p><\/div>\n

\"testResults_C\"<\/a>

testResults_C<\/p><\/div>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

Let us annotate each figure automatically with its file name (but excluding the file type ending) using ImageMagick<\/a>.<\/p>\n

\n

for i in $(ls *.png); do convert $i -background Orange label:${i%.png*} +swap -gravity Center -append ${i%.png*}.withAnno.png; done<\/code><\/p>\n<\/div>\n

 <\/p>\n

On the top of each figure, an orange bar with the respective file name has now been added.<\/p>\n

\"annotated<\/a>

annotated testResults_A<\/p><\/div>\n

\"annotated<\/a>

annotated testResults_B<\/p><\/div>\n

\"annotated<\/a>

annotated testResults_C<\/p><\/div>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

UPDATE: I found it necessary to manually set the font size in several cases. It is hereby important to set option pointsize<\/em> as the first option in the list.<\/p>\n

\n

for i in $(ls *.png); do convert $i -pointsize 60<\/strong> -background Orange label:${i%.png*} +swap -gravity Center -append ${i%.png*}.withAnno.png; done<\/code><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
