Inserting images to a report

Binding links to images

An image is a digital representation of a picture. JReport supports the following image formats: .bmp, .gif, .jpg, and .png. This section describes how to use the image component.

See an example: The SampleComponents catalog, included with JReport Designer, contains reports that have examples of how each component type could be used in a report. For the image component example, open <install_root>\Demo\Reports\SampleComponents\ForImage.cls.

Inserting images to a report

An image can be inserted in the report areas listed in Component placement.

Position the mouse pointer at the destination where you want to insert the image.
Do any of the following.
- Drag from the Components panel.
- Click Insert > Image.
- Click Home > Insert > Image.
In the Select an Image dialog, select the image you want to use.
- If you want to use an image from your local file system, use the Look in drop-down list to browse for the image, then click Open. If the image file is not in the current catalog directory, you will be prompted to copy it to the directory.
- If you want to use an image via URL, enter the URL in the URL text box and then click OK.
Click Open to insert the image into the destination.

Notes:

If want to use an image via URL and you are in an intranet, to successfully access the image, you need to add the parameters -DproxyHost=XXX -DproxyPort=XX to the batch file JReport.bat, which is located in <install_root>\bin.
If you insert an image via URL into a report, when the report is saved, only the URL information will be saved into the report template.

Binding links to images

You can make the images in a report link with other reports, locations specified by URLs, e-mail addresses, or Blob data type fields. The links can either be simple links or conditional links. With conditional links, different targets can be loaded based on different conditions.

To bind a link to an image, right-click the image and click Link on the shortcut menu, then take the same procedure as described in Binding Links to Labels.
