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.

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 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

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.

NoteNote

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.

You can change some default settings for this renderer by changing the device information settings. For more information, see Reporting Services Device Information Settings.
