Force font size(width and height) for iconfont

[chenyinchang]

I have a problem about iconfont in a long time. I use "lv_font_conv " which convert a “my_iconfont.c” file. And then try to modify ".c" file which have "offset x" and "offset y" for aligning icons to same column. But I try my best，you can see result below here ：

So, I want to know how force font size instead of compact format

Thanks
