# Visualforce Considerations

Keep the following considerations in mind when using the `<apex:canvasApp>` component:

-   The `<apex:canvasApp>` component is available only in organizations that have Canvas enabled and in Visualforce pages at version 27.0 or higher.
-   If you include a canvas app on an object detail layout, you must provide the height of the canvas app in the page layout as well as in the `<apex:canvasApp>` component.
-   Location—If the canvas app is in a Visualforce page, then the `Environment.displayLocation` field contains the value `Visualforce`.
