剪切Postscript图片中的多余边框
最近用plplot画图,其cairo ps库生成的ps图片总是不能合理地剪切掉多余的边框,于是乎自己写了一个小脚本epscrop,用修改ps图的BoundingBox.
#!/bin/bash # check if the argument is provided. if [ $# -lt 1 ] then echo "no file specified." exit fi fname=$1 #check if the file exits. if [ ! -f $fname ] then echo "file $fname not exists." exit fi #get the bounding box box=$(gs -sstderr=%stdout -dQUIET -dBATCH -DNOPAUSE -sDEVICE=bbox $fname 2>&1 | sed -n -e "s/%%BoundingBox:\(.*\)/\1/p") #change the bounding box sed -i -e "/%%DocumentMedia:/d" $fname sed -i -e "s/\(%%BoundingBox:\)\(.*\)/\1$box/" -e "s/\(%%PageBoundingBox:\)\(.*\)/\1$box/" $fname
用法: ./epscrop psfile, 效果如下,
