Solution 1

It gets fuzzy because you're using a font to come up with the image of a barcode. PROPERLY draw the barcode yourself and you won't have that problem.

Check this: GenCode128 - A Code128 Barcode Generator[^].

But, keep in mind that the smaller you make the barcode, the harder it is to keep the proper spacing between the bars and the width of bars to the required distances.

i used 'zxing.net' to draw barcode
http://zxingnet.codeplex.com/
but it makes 15 character string 134 pixel wide,apart of zxing i found no library which can draw barcode in vary small width(90-100 pixel 15 chars).

mostly online library has parameters for barcode height,bar weight,margin
i have no clue how to contain it in less width.

L = (11 * C + 35) * X
where:
L = Overall length (not including Quiet Space)
C = Number of DATA characters (not including START, CHECK, or STOP)
X = length of x-dimension

Example: Code128 -> C = 7, X = 0.010"
L = (11 * 7 + 35) * 0.010” = 1.120” without Quiet Zones
or 1.120” + 2 * Max(10 * 0.010”, 0.25”) = 1.370” with Quiet Zones

Example: Code128Barcode -> C = 14, X = 0.010"
L = (11 * 14 + 35) * 0.010” = 1.890” without Quiet Zones
or 1.890” + 2 * Max(10 * 0.010”, 0.25”) = 2.140” with Quiet Zones

according to this formula we can set barwidth to 0.010 but problem is how to draw an image out of it
it takes all integer values to draw a rectagular bar .
Grafics.DrawRectangle()
https://msdn.microsoft.com/en-us/library/system.drawing.graphics.fillrectangle(v=vs.110).aspx

this software gives flexibility to adjust width like i want
http://www.barcodemaking.com/

it lets you reduce width by specifying width in mills. or pixels ,i want something like that.

I can't tell you anything beyond what I already have. If you want a custom solution that no library can provide you have to write one yourself. This is what I've already told you.
