*Since Camel 2.10*

// HEADER START
*Only producer is supported*
// HEADER END

The FOP component allows you to render a message into different output
formats using http://xmlgraphics.apache.org/fop/index.html[Apache FOP].

Maven users will need to add the following dependency to their `pom.xml`
for this component:

[source,xml]
------------------------------------------------------------
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-fop</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>
------------------------------------------------------------

== URI format

[source,text]
----------------------------
fop://outputFormat?[options]
----------------------------

== Output Formats

The primary output format is PDF but other output
http://xmlgraphics.apache.org/fop/0.95/output.html[formats] are also
supported:

[width="100%",cols="10%,10%,80%",options="header",]
|=======================================================================
|name |outputFormat |description

|PDF |application/pdf |Portable Document Format

|PS |application/postscript |Adobe Postscript

|PCL |application/x-pcl |Printer Control Language

|PNG |image/png |PNG images

|JPEG |image/jpeg |JPEG images

|SVG |image/svg+xml |Scalable Vector Graphics

|XML |application/X-fop-areatree |Area tree representation

|MIF |application/mif |FrameMaker's MIF

|RTF |application/rtf |Rich Text Format

|TXT |text/plain |Text
|=======================================================================

The complete list of valid output formats can be found in the `MimeConstants.java` source file.

== Endpoint Options

// component options: START
The FOP component supports 3 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *basicPropertyBinding* (advanced) | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *bridgeErrorHandler* (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean
|===
// component options: END



// endpoint options: START
The FOP endpoint is configured using URI syntax:

----
fop:outputType
----

with the following path and query parameters:

=== Path Parameters (1 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *outputType* | *Required* The primary output format is PDF but other output formats are also supported. |  | FopOutputType
|===


=== Query Parameters (5 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *fopFactory* (producer) | Allows to use a custom configured or implementation of org.apache.fop.apps.FopFactory. |  | FopFactory
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *userConfigURL* (producer) | The location of a configuration file which can be loaded from classpath or file system. |  | String
| *basicPropertyBinding* (advanced) | Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
| *synchronous* (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean
|===
// endpoint options: END
// spring-boot-auto-configure options: START
== Spring Boot Auto-Configuration

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

[source,xml]
----
<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-fop-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
----


The component supports 4 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *camel.component.fop.basic-property-binding* | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | Boolean
| *camel.component.fop.bridge-error-handler* | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | Boolean
| *camel.component.fop.enabled* | Enable fop component | true | Boolean
| *camel.component.fop.lazy-start-producer* | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | Boolean
|===
// spring-boot-auto-configure options: END



The location of a configuration file with the following
http://xmlgraphics.apache.org/fop/1.0/configuration.html[structure].
The file is loaded from the classpath by
default. You can use `file:`, or `classpath:` as prefix to load the
resource from file or classpath. In previous releases the file is always
loaded from file system.

== Example

Below is an example route that renders PDFs from xml data and xslt
template and saves the PDF files in target folder:

[source,java]
---------------------------------
from("file:source/data/xml")
    .to("xslt:xslt/template.xsl")
    .to("fop:application/pdf")
    .to("file:target/data");
---------------------------------
