golang版 终端打印机
python版 终端打印机 https://github.com/hellflame/terminal_printer
- 默认输出(第一次运行需要下载字体文件, 下载问题在后面说明)
- 给定输出文字(字体库支持的文字)
- 彩色图片输出
- 图片灰度图(在终端分辨率较高的情况下输出)
- 修改默认尺寸输出
- 镂空效果 (交换填充字符)
- 修改灰度边界阈值(
shade越大, 镂空区域判定越模糊, 图片输出有同样作用)
- 切换填充字符
go get -u github.com/hellflame/printer若安装过程出现 golang**/x/image 下载失败等等连接失败的话有以下两种选择
查看 https://github.com/hellflame/printer/releases
根据运行操作系统选择下载可执行文件，放在当前路径或可执行路径即可
在支持 make 的环境中，只需 make build 或指定对应操作系统即可
make build也可以手动打包支持当前操作系统
# dynamic build
go build
# or
# static build
CGO_ENABLED=0 go build -ldflags "-s -w" 则可在当前目录得到可执行文件

-t设置输出文字，默认作者名 (需要有字体，并且字体中包含文字)-c设置颜色输出，默认 0 表示随机颜色-f设置填充字符索引，部分索引输出为空白，默认输出i--font设置下载字体索引或给定字体路径 (图片不需要字体)-g图片是否启用灰度模式-s灰度滤波边界，即灰度二值化的边界值-e设置输出高度，默认当前终端高度 (若无法获得，将使用一固定高度)-w设置输出宽度，默认当前终端宽度 (若无法获得，将使用一固定宽度)
部分使用示例在开头有展示
import "github.com/hellflame/printer/draw"
func main(){
img = draw.Clip(draw.Text(text, fontPath))
result := draw.GeneratePixel(&img, filter, color, reverse?, gray?, shade)
do_something_with(result)
}由于项目基于原python项目迁移，已存在字体库 https://github.com/hellflame/terminal_printer/tree/master/fonts
项目默认使用原项目字体路径，但只支持 ttf 字体
若自动下载字体缓慢，甚至下载失败，可选择手动下载字体文件，放在 ${HOME}/.terminal_fonts/ 即可
