LiveCode PDF Viewer
The PDF viewer external is a LiveCode Business feature allowing a PDF view to be loaded within your application. Get access to commonly used PDF functions as well as the ability to extract and manipulate data selection from the PDF document.
Load a PDF, navigate between pages, zoom in and out, switch between browse and select modes, and display your selection as an image or text. The new LiveCode PDF viewer external gives you access to the features commonly associated with displaying a PDF document. While it has long been possible in LiveCode to embed a web view to show PDF’s in your app, this can be quite restrictive in some situations.
The LiveCode PDF Viewer external allows you to extract the selected data in either text or image form making this data available for manipulation. For example you can put your extracted text into a field, display it in a datagrid or use it in any way you need to in LiveCode.
