Specifying formats for container fields
You can control how FileMaker Pro displays content in container fields.
Container fields store and display pictures, QuickTime files, sounds, movies, and files of any type. (For more information, see Using data in container fields.) By default, container fields display:
When you format a container field, you can set scaling and alignment options for images. The formatting options you choose affect the display in FileMaker Pro only, and do not affect the original data.
To specify formats for container fields:
In Layout mode, select one or more container fields.
For more information, see Selecting objects.
Click Inspector Inspector button in the layout bar, then click Data.
In the Data Formatting area, click Graphic Graphic button, then select the formats you want to use.
From the Format list, choose Crop to frame. FileMaker Pro crops the image if it's too large to fit within the field boundaries.
From the Format list, choose Reduce image to fit, Enlarge image to fit, or Reduce or Enlarge image to fit.
Unless you also select Maintain original proportions, the image is distorted to fit the proportions of the field boundaries.
For Alignment, choose horizontal and vertical alignments.
Choose Images (JPEG, PNG, etc.).
Choose Interactive content (PDF, MP3, etc.). When this option is selected, the field becomes an interactive container. You can work interactively with files in interactive containers. For example, when a PDF is inserted into the field, you can scroll through pages, zoom in and out, and copy text. When an audio file or video file is in the field, you can play the media and use all available controls for that media type, such as pause, play, and fast-forward.
To have audio and video play when you display the container field, also select Start playback automatically. If this option is not selected, you start audio or video files by clicking the play control.
If you select Interactive content for a field:
You can use this option for container fields that store embedded data, data stored externally, or local references to files.
