| settings | The settings object to change | | name | The name of the setting | | value | The new value for the setting (encoded in UTF-8) |
Returns1 if the setting was updated successfully and 0 otherwise.See alsoSetting, wkhtmltopdf_create_global_settings, wkhtmltopdf_set_global_settingParameters
| settings | The settings object to inspect | | name | The name of the setting to read | | value | A buffer of length at least vs, where the value is stored (encoded in UTF-8). | | vs | The length of value |
Returns1 If the the setting exists and was read successfully and 0 otherwise
This is the main method for the conversion process, during conversion progress information warning, and errors are reported using the supplied call backs. Once the conversion is done the output pdf (or ps) file will be placed at the location of the "out" setting supplied in the global settings object during construction of the converter. If this setting is not supplied or set to the empty string, the output can be retrieved using the wkhtmltopdf_get_output function.
\paragm converter The converter to perform the conversion on.
Returns1 on success and 0 otherwise
Conversion is done in a number of named phases, this function will retrieve the number of the current conversion phase, which will be a number between 0 and wkhtmltopdf_phase_count(converter)-1.
The description (name) of any phase can be retrieved by calling the wkhtmltopdf_phase_description method.
Parameters
| converter | The converter to find the current phase of |
ReturnsThe current phase of the supplied converterParameters
| converter | The converter to query |
ReturnsThe total number of phases in the conversion processSee alsowkhtmltopdf_current_phase, wkhtmltopdf_phase_description
Return the largest HTTP code greater than or equal to 300 encountered during loading of any of the supplied objects, if no such error code is found 0 is returned. This function will only return a useful result after wkhtmltopdf_convert has been called.
Parameters
| converter | The converter to query |
ReturnsThe HTTP error code.
| CAPI | ( | void | | ) | |
Destroy a global settings object.
add an object (web page to convert)
Set the function that should be called once the conversion has finished.
Set the function that should be called when progress have been done during conversion.
Set the function that should be called whenever conversion changes phase.
Set the function that should be called when an errors occurs during conversion.
Set the function that should be called when an warning message is issued during conversion.
Destroy a wkhtmltopdf converter object.
Normally one would not need to call this since ownership of the settings object is transfarred to the converter.
An object must be destroyed to free up its memory, once it has been destroyed it may no longer be accessed.
Parameters
| settings | The converter object to destroy | | converter | The converter object on which warnings we want the callback to be called | | cb | The function to call when warning message is issued | | converter | The converter object on which errors we want the callback to be called | | cb | The function to call when an error occurs |
The number of the new phase can be found by calling wkhtmltopdf_current_phase
Parameters
| converter | The converter which phase change events to call back from | | cb | The function to call when phases change |
See alsowkhtmltopdf_current_phase, wkhtmltopdf_phase_count, wkhtmltopdf_phase_description
The progress in percent within the current phase is given as an integer to the callback function.
Parameters
| converter | The converter which progress events to call back from | | cb | The function to call when progress has occurred. |
See alsowkhtmltopdf_progress_descriptionParameters
| converter | The converter which finish events to call back from | | cb | The function to call when the conversion has finished has occurred. |
See alsowkhtmltopdf_convert
Add the object described by the supplied object settings to the list of objects (web pages to convert), objects are placed in the output pdf in the order of addition. Once the object has been added, the supplied settings may no longer be accessed, it Wit eventually be freed by wkhtmltopdf. If a none NULL and none empty utf8 encoded string is supplied to data, this HTML content will be converted instead of the content located at "page" setting of the supplied object settings instance.
Parameters
| converter | The converter to add the object to | | settings | The setting describing the object to add | | data | HTML content of the object to convert (encoded in UTF-8) or NULL |
| CAPI | ( | wkhtmltopdf_converter * | | ) | |
Create a wkhtmltopdf converter object.
The converter object is used to convert one or more objects(web sides) into a single pdf. Once a settings object has been parsed, it may no longer be accessed, and will eventually be freed. The returned converter object must be freed by calling wkhtmltopdf_destroy_converter
Parameters
| settings | The global settings to use during conversion. |
ReturnsA wkhtmltopdf converter object
| CAPI | ( | [wkhtmltopdf_global_settings](structwkhtmltopdf global settings.html) * | | ) | |
Create a new global settings object for pdf conversion.
Create a new global settings object for pdf conversion, settings can be altered with wkhtmltopdf_set_global_setting, and inspected with wkhtmltopdf_get_global_setting. Once the desired settings have been set a converter object can be created using \reg wkhtmltopdf_create_converter.
ReturnsA wkhtmltopdf global settings object
| CAPI | ( | [wkhtmltopdf_object_settings](structwkhtmltopdf object settings.html) * | | ) | |
Create an object used to store object settings.
Create a new Object settings object for pdf conversion, settings can be altered with wkhtmltopdf_set_object_setting, and inspected with wkhtmltopdf_get_object_setting. Once the desired settings have been set the object can be added to a converter by calling wkhtmltopdf_add_resource.
Returnsan object settings instance
