vscode一體化導(dǎo)出drawio

需要的工具:vscode, draw.io擴(kuò)展,draw.io桌面版 、python

提示:這個(gè)方法并沒有簡化流程,只是能夠減少打開窗口,在vscode中直接查看原始文件,導(dǎo)出文件,效率并沒有顯著提升。

啰嗦的部分:
drawio流程圖繪制軟件比visio好用。而且vscode有插件。vs插件的優(yōu)點(diǎn)在于支持mermaid流程圖,缺點(diǎn)非常明顯不支持指定分辨率圖像導(dǎo)出。
網(wǎng)上檢索發(fā)現(xiàn)drawio的桌面版可以在命令行操作。在drawio安裝目錄下運(yùn)行cmd,然后通過draw.io -help 命令可以查看全部命令。
查看命令發(fā)現(xiàn)沒有針對性的dpi設(shè)置。我就想到給圖片輸入寬度和高度的方式。根據(jù)我猜測這個(gè)寬度和高度應(yīng)該對應(yīng)的就是像素點(diǎn)數(shù)量,所以我就按照實(shí)際尺寸,以及dpi的定義
寫了一個(gè)命令, 發(fā)現(xiàn)可用。但是每次都要計(jì)算寬度、高度、調(diào)用cmd命令窗口,太麻煩。功能強(qiáng)大的python加上插件齊全的vscode能不能全部實(shí)現(xiàn)呢?
折騰了幾個(gè)小時(shí),終于搞定了。

進(jìn)入正題:
1、安裝draw.io插件,和桌面版,記住桌面版的路徑
2、繪制好的圖片有一個(gè)實(shí)際的尺寸,記住實(shí)際尺寸的寬和高
3、python轉(zhuǎn)換 寬度

dpivalue=600#dpi
realwidth=89.4#mm
realheight=81.2#mm
width=round(dpivalue*realwidth/25.4)
height=round(dpivalue*realheight/25.4)

4、 構(gòu)造命令行,不嫌麻煩可以自己寫完整目錄

inputfilepath=r'F:\BaiduNetdiskWorkspace\00typora\大論文\drawio\算法流程圖.drawio'
outputfilepath=r'F:\BaiduNetdiskWorkspace\00typora\大論文\drawio\test.png'
starttext=r'draw.io -x '
midletext=r" -f png -t --width "+str(width)+r" --height " +str(height)+r" -o "
commandtext1=starttext+inputfilepath+midletext+outputfilepath

5、 改變python文件工作目錄并執(zhí)行命令

path="D:/draw.io/"#安裝文件夾
os.chdir( path )# 修改當(dāng)前工作目錄
v2=os.system(commandtext1)

完整的代碼

代碼量并不大,非常簡單
