在 IronBarcode 中，您可以灵活地调整条形码的大小、添加边距、更改颜色，并将其保存为各种流行的文件格式。 此外，您可以调整DPI设置，以实现对图像细节的更精细控制。
自定义条形码外观：可通过多种方法修改条形码的大小和颜色：
ResizeTo(500, 500)：将条形码调整为500x500像素。ChangeBarColor：改变条形码中的条纹颜色。ChangeBackgroundColor：更改背景颜色。

// Set margins in pixels

// Set the color of the barcode

// And save our barcode as an image:

// Another supported feature is Mil Sizing
// Mil is a measurement unit used by the barcode scanner manufacturers to specify the minimum of one barcode bar, and at what distance the barcode can be scanned.
// It represents (1 / 1000)th of an inch

// This will resize the barcode width to 13 mil, at 96 DPI by default

// This will resize the barcode width to 10 mil and and the height to 1.5 inches, at 96 DPI by default

// This will resize the barcode width to 7.5 mil and the height to 2 inches, with the DPI set to 200
