What's New in Essential Studio for Xamarin.Forms

ESSENTIAL STUDIO 2023 VOLUME 4

What's New in Essential Studio for Xamarin.Forms

Our last release of the year improves our Xamarin.Forms offering with PDF Library functionality to split PDFs without compromising accessibility tag integrity and preserve TIFF images in PDF conversion, as well as enhancements to pivot table grouping in Excel Library.

Excel Library

Grouping in pivot tables

The Excel Library (XlsIO) now supports grouping date and time fields in pivot tables. Users can group pivot data based on the following categories:

  • Date
  • Month
  • Year
  • Quarter
  • Hour
  • Minute
  • Second

Font fallback in Excel-to-PDF conversion

The Excel Library now allows the configuration of fallback fonts for Unicode text during the conversion of Excel files to PDF or image files. These fallback fonts come into play when the rendering engine encounters Unicode text that lacks a corresponding glyph in the specified fonts.

Users can configure fallback fonts in the following ways:

  • Initialize default fallback fonts for Unicode text.
  • Set custom fonts as fallback fonts for specific script types, including Arabic, Hebrew, and Chinese.
  • Set custom fonts as fallback fonts for a particular range of Unicode text.

TIFF image preservation in file conversion

The Excel Library now preserves TIFF images in converted PDFs or images exactly as they appear in the input Excel document. For example, you can convert medical reports with TIFF images of X-rays, MRIs, and CT scans from an Excel document to a PDF or an image.

Excel functions

The Excel Library now supports creating and parsing the following Excel functions:

  • LAMBDA: Allows custom formula parameters and logic.
  • SORT: Arranges the cell range values in ascending or descending order.
  • BYROW: Applies a LAMBDA to each row and returns an array of the results.
  • BYCOL: Applies a LAMBDA to each column and returns an array of the results.
  • TOROW: Transforms an array into a single row.
  • TOCOL: Transforms an array into a single column.
  • CHOOSEROWS: Returns specified rows from an array.
  • CHOOSECOLS: Returns specified columns from an array.
  • TEXTSPLIT: Splits the cell text across rows or columns.
  • TEXTBEFORE: Returns the text before a given character.

PDF Library

PDF split enhancement

Split PDF documents without sacrificing the integrity of accessibility tags. Accessibility is crucial for users relying on screen readers and other assistive technologies.

PDF optimization for reduced file size

Improved document operations to reduce file sizes. By removing unused elements and identifying identical resources, experience heightened efficiency in both PDF merging and splitting.

Enhanced digital signature validation

Now, effortlessly access certificates from the Document Security Store (DSS) and retrieve CRL lists for enhanced validation during signature verification. Elevate your document security with these streamlined features.

PowerPoint Library

Enhancement for PowerPoint conversion to PDF or image

TIFF image preservation

The .NET PowerPoint Library now preserves TIFF images in converted PDFs or images exactly as they appear in the input presentation. For example, you can convert medical reports with TIFF images of X-rays, MRIs, and CT scans from a presentation to a PDF or an image.

Word Library

Create equations using LaTeX

The .NET Word Library allows you to create mathematical equations by specifying a LaTeX string in a Word document. With this feature, you can easily add an equation created using a LaTeX editor into a Word document.

Enhancements for Word conversion to PDF or image

Fallback font for Unicode text

The .NET Word Library now allows the configuration of fallback fonts for Unicode text during the conversion of Word files to PDF or image files. These fallback fonts come into play when the rendering engine encounters Unicode text that lacks a corresponding glyph in the specified fonts.

Users can configure fallback fonts in the following ways:

  • Initialize default fallback fonts for Unicode text.
  • Set custom fonts as fallback fonts for specific script types, including Arabic, Hebrew, Chinese, and more.
  • Set custom fonts as fallback fonts for a particular range of Unicode text.

TIFF image preservation

The .NET Word Library now preserves TIFF images in converted PDF or images exactly as they appear in the input Word document. For example, you can convert medical reports with TIFF images of X-rays, MRIs, and CT scans from a Word document to PDF or an image.
