C# Drawing text on image keeps coming out too blurry

Asked by twcadmin in C# Programming Language, Miscellaneous Web Development, .NET

Tags: c# .net

I'm trying to draw a barcode image. I have the barcode font installed on my server and using the code below i can draw text to my screen using the font BUT it comes out too blurry so when i go to print it, the barcode is unuseable. If i type the same barcode using microsoft word and print it out it comes out perfectly clear so i know theres nothing wrong with the font or the printer. I changed the font to Arial so everyone else can see the code for themselves and test it out if they want.

I'm lost as to how i'm suppose to make this image more clear.

Excuse the sloppy code but i'm learning and experimenting a lot.Start Free Trial
