Method
VipsImagehistory_printf
Declaration [src]
int
vips_image_history_printf (
VipsImage* image,
const char* format,
...
)
Description [src]
Add a line to the image history. The format and arguments are expanded, the
date and time is appended prefixed with a hash character, and the whole
string is appended to the image history and terminated with a newline.
For example:
vips_image_history_printf(image, "vips invert %s %s",
in->filename, out->filename);
Might add the string
"vips invert /home/john/fred.v /home/john/jim.v # Fri Apr 3 23:30:35 2009\n"
VIPS operations don’t add history lines for you because a single action at the application level might involve many VIPS operations. History must be recorded by the application.
