Configuring System Messages
DWT provides various system messages during all parts of runtime. Some of these messages are errors which are useful for debugging/reporting purposes, such as indicating that the Dynamsoft Service has not been installed on end user’s system. Other messages provide information directly to the end user, such as labelling the image source selection prompt overlay (scanner selection).
These system messages are configurable. Notably, we recommend changing these system messages for the purposes of translating the default English messages to other localizations.
Configuring the CustomizableDisplayInfo Object
Most system messages are configurable with the Dynamsoft.DWT.CustomizableDisplayInfo object, which may be modified within the dynamsoft.webtwain.config.js configuration resource file. This resource file has a commented-out definition of the object, which contains the default system messages. To alter the default messages, simply un-comment the object and change its properties:
Dynamsoft.DWT.CustomizableDisplayInfo = {
errorMessages: {

Configuring the _show_install_dialog() Function
The Dynamsoft._show_install_dialog() function defined in the dynamsoft.webtwain.install.js resource file generates the Dynamsoft Service installation dialog box, pictured here:
As the dialog box contains instructions for installing the Dynamsoft Service, consider altering the message strings for localization purposes. Generally we discourage directly modifying the resource files, but this dialogue function contains styling and messaging which may be tailored the web application itself. Try not to alter the platform detection logic too greatly, as this may interfere with the Dynamsoft Service installation procedure. Please contact the support team for any further questions.
