Recommend an open source free drawing software draw IO exportable vector graph

Problem description

About drawing , Microsoft Visio It's a good choice , But not supported mac Next use , I won't support it linux Desktop system , And it's a paid software .

Recommend a free software , The official website address is draw.io, Don't rush to download and install locally , You can try to draw on the line , The trouble with browser based image rendering is that you need to wait for loading at the beginning of this period of time , It's usually faster .

Downloading and installing the desktop version is just as easy , Go https://github.com/jgraph/drawio-desktop/releases/ Download and install the latest version . contain windows 、mac as well as linux Version of .

Insert data formula

You need to set the data formula , As shown in the figure ： First click on the top Other , And then click Mathematical typesetting that will do .

Then you can start writing data formulas , After writing, click elsewhere to see the effect .

Export vector graph eps

In fact, I personally think draw.io export eps Than visio A little more convenient , Although they are exported first pdf Re convert to eps Format .

use first draw.io Draw pictures , After drawing , Click on the top left file （File）, Choose... Below Export to And select pdf Format .

Be careful ： Single page export is recommended , So you don't have to cut .

In this way, the exported will automatically crop the boundary , There won't be many blanks .

Then use Acrobat Pro open pdf file , find export The function of . choice embedded PostScript.

The exported will be eps Format picture .

The input of Greek letters

If you need to enter Greek letters , It is recommended to use the input method directly Greek alphabet option , Then open the soft keyboard and enter , It's more convenient . For example, Sogou input method .

ασφγηξκλζχψωβνμξγ

In this case, it can replace the previous mathematical formula , Because if you use $$ The mathematical formula $$ Then convert it to eps When the format , Will become Not optional . This should be related to eps The format of the picture has some conflicts , So we should not consider this method as much as possible .

For other Fonts

For example, it is often used when writing formulas mathcal How to write it $\mathcal{A}$ yes $$\mathcal{A}$$ . In this case ,draw.io It can also be converted to this form , As mentioned above , But that “ Unselectable ” How to solve the problem of ？

Consider a small trick ： stay Write the same letters in the same position with the background color . in other words , Use the data formula to write , Another time, write in normal font , But the color is consistent with the background color , If when exporting pdf When you file , When this character is selected , In fact, the background color is selected A , instead of $\mathcal{A}$ . But the effect has been achieved .

summary

Share some methods and tools for writing papers , I hope I can help my friends .
