Comments

LEADTOOLS currently supports the following HTML rendering engines:

L_HTMLENGINE_IE (Internet Explorer)

This engine uses the default Internet Explorer rendering engine that comes with the Windows operating system.

This engine is only supported by the Windows platform.

L_HTMLENGINE_WEBKIT WebKit, Requires additional download

This engine uses the WebKit rendering engine. To enable it, the user must first download and install the operating system-related files from https://wkhtmltopdf.org/downloads.html.

The library needed by LEADTOOLS is wkhtmltox.dll for Windows and wkhtmltox.so for Linux. Extracting this file from the setup above and then placing it next to the other LEADTOOLS libraries is sufficient.

Note that the WebKit rendering engine is not included in your LEADTOOLS setup and has to be obtained separately by the user.

In addition to the above, LtWebKitEngine?.dll/so from your LEADTOOLS setup must be included in the application (next to lfhtm?.dll/so).

The WebKit rendering engine is supported by the Windows, Linux and macOS platforms.

L_HTMLENGINE_AUTO

The following behavior occurs when L_HTMLENGINE_AUTO (the default value) is used:

Windows: LEADTOOLS will search for ltWebKitEngine and wkhtmltox.dll. If found, then L_HTMLENGINE_WEBKIT is used. Otherwise, L_HTMLENGINE_IE is used.
Linux/macOS: LEADTOOLS will always search for ltWebKitEngine and wkhtmltox.so. If not found, loading of HTML is not supported.
