How to use EXIF macros for watermarks for annotation macros in C# and ByteScout Watermarking SDK

See how to use EXIF macros for watermarks to have annotation macros in C#

The sample source codes on this page will demonstrate you how to make annotation macros in C#. ByteScout Watermarking SDK was made to help with annotation macros in C#. ByteScout Watermarking SDK is the software development kit that helps to quickly implement adding of watermarks on top of PNG, JPG, BMP images as well as on multipaged TIFF files. You may select ready to use presets or create your own preset with semitransparent logo images, text lines with adjustable font size, family, color, rotation.

Fast application programming interfaces of ByteScout Watermarking SDK for C# plus the instruction and the code below will help to learn how to use EXIF macros for watermarks. For implimentation of this functionality, please copy and paste code below into your app using code editor. Then compile and run your app. Enjoy writing a code with ready-to-use sample C# codes to implement annotation macros using ByteScout Watermarking SDK.

ByteScout Watermarking SDK – free trial version is on available our website. Also, there are other code samples to help you with your C# application included into trial version.
