Hi Guys, in the blog you will learn how to categorize hyperlinks in order to select the appropriate method for processing each of these links. You may also explore and extract embedded MOL file. Moreover, we now provide a solution when rendering bigger files (having millions of pages in the sheet(s)). You may get total page count before converting to PDF/Image, This is a good thing to know to decide whether to render or not to render. You may have a look at the release notes to get the complete list of features and bug fixes which are part of this new release. So let’s not wait another moment to review the release notes. To get essence of the public release (Aspose.Cells for .NET v19.8), I am giving you preview of the new features and other enhancements available in it.
Detect Hyperlink Type
There can be different types of hyperlinks which can be used in an Excel file like external, cell reference, file path and email. Our new release has introduced an enumerator TargetModeType which represents the type of hyperlink. A new property LinkType is introduced in Hyperlink class which return the hyperlink type using above mentioned enumerator. See the document for your reference. Here is an example which can be used to exercise this new feature.
Get total page count before PDF/image creation
Well, the title is explaining this new feature. When a file has too many pages, the process of converting to pdf/image may use too much memory and CPU, and OOM exception may be thrown. Getting total pages count before converting can indicate this risk, and do some actions (e.g. skip this file) or print the selected pages to avoid the undesired results. For example one of my sample Excel file (870 KB) was showing about 38 million pages. Just imagine, what will happen if you come across a conversion containing such a huge number of pages. Following is an example to show the usage of new classes SheetPrintingPreview and WorkbookPrintingPreview. Both of these classes contain a property EvaluatedPageCount which returns the page count of the printout or PDF file. See the document for your complete reference.Extracting Embedded MOL File
As you know that molecular data file created in the MDL Molfile format, a chemical file format; contains plain text information and stores information about atoms and bonds; often used as a standard exchange format for molecular information. This type of file can be embedded in the Excel file. In this latest release, support is provided to extract object of such an uncommon type i.e. MOL. The following code snippet demonstrates extracting embedded MOL file and saving it to disk. See the document for your reference.Other enhancements and fixes
