Process(LowCodeLoadOptions, LowCodeSaveOptions)

Converts template file to images

public static void Process(
    LowCodeLoadOptions loadOptions,
    LowCodeSaveOptions saveOptions)

Parameters

loadOptions LowCodeLoadOptions

Options for input and loading

saveOptions LowCodeSaveOptions

Process(LowCodeLoadOptions, LowCodeSaveOptions, AbstractLowCodeSaveOptionsProvider)

Converts template file to images

public static void
    Process(
        LowCodeLoadOptions loadOptions,
        LowCodeSaveOptions saveOptions,
        AbstractLowCodeSaveOptionsProvider provider)
{
}

Parameters

loadOptions LowCodeLoadOptions

Options for input and loading

saveOptions LowCodeSaveOptions
