For optimizing files in-place with jpegtran, especially from scripts and when dealing with lots of pictures, it’s handy to be able to specify input file as -outfile.<\/p>\n
But there’s a catch:<\/p>\n
Steps to reproduce:
\n0. Have a large JPEG file, or, alternatively, somewhat slow CPU
\n1. `jpegtran -optimize -copy all -perfect -outfile large.jpg large.jpg`
\n2. Hit Ctrl-C before the command finishes<\/p>\n
Result:
\nYou now have a broken large.jpg with only part, if any, of the image data remaining.<\/p>\n
What I expect to happen:
\nTo have large.jpg as it was before I invoked jpegtran.<\/p>\n
Workarounds:
\nObviously the traditional workaround of specifying an intermediate temporary output file, then replacing the original with the temporary file only once jpegtran has finished.<\/p>\n","protected":false},"excerpt":{"rendered":"
