Exporting to an Image File
The Image rendering extension renders a report to a bitmap or metafile. By default, the Image rendering extension produces a Tagged Image File Format (TIFF) file of the report, which can be viewed in multiple pages. When the client receives the image, it can be displayed in an image viewer and printed. This topic provides Image renderer-specific information and describes exceptions to the rendering rules.
The Image rendering extension can generate files in any of the formats supported by GDI+: BMP, EMF, EMFPlus, GIF, JPEG, PNG, and TIFF. For TIFF format, the file name of the primary stream is ReportName.tif. For all other formats, which render as a single page per file, the file name is ReportName_Page.ext where .ext is the file extension for the chosen format. To produce a file in another Image-supported format, specify any of the above listed strings in the OutputFormat DeviceInfo setting.

The following table shows the file extension and MimeType for each Image renderer format.

Rendering Multiple Pages
TIFF is the only format that supports multiple page documents in a single file. Other formats, such as JPG or PNG, output one page at a time and require a separate call to the rendering extension for each page.
Interactivity
Interactivity is not supported in any Image formats generated by this renderer. The following interactive elements are not rendered:
Hyperlinks
Show or Hide
Document Map
Drillthrough or clickthrough links
End user sort
Fixed headers
Bookmarks
TIFF Limitations
By default, if Reporting Services is installed on a computer with Microsoft Windows XP or Windows Server 2003, vertical text does not render correctly in TIFF. To render vertical text correctly, you must install the files for complex script and right-to-left languages.
Note
To enable complex scripts and right-to-left languages, open Regional and Language Options in Control Panel. In the Regional and Language Options dialog box, click the Languages tab and select Install files for complex script and right-to-left languages (including Thai), and then click OK.
