Aspose team is very excited to announce the new version of Aspose.PDF for .NET 18.7. This new release has been rolled out with quite excited features and enhancements. In text editing scenarios, applying gradient shading or pattern colorspace to the text is now available in latest release of the API. Aspose.Pdf.Color Class has further been enhanced by introducing new property of PatternColorSpace, which can be used to specify shading colors for the text. An example demonstrating the usage of mentioned feature can be checked at following link in API documentation.

In particular scenarios where text removal from PDF is an important requirement, this new method works quite efficiently and fast.
