Subject: fixed maxlength for sprintf_alloc 50 was not enough ... 1024+strlen(fmt) is much... 
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;ds=sidebyside;h=e8c71854ca1387f5db46e01035733e1eb5202050;p=rrdtool.git

fixed maxlength for sprintf_alloc 50 was not enough ... 1024+strlen(fmt) is much better. This
makes imginfo work even when there are long image paths.
