10-22 Publishing Reports to the Web with Oracle Reports Services ■ Removal of the printer dependency. If, when generating report output, there is no valid printer queue available not found from TK_PRINTER,ORACLE_PRINTER,PRINTER, or uiprint.txt, the surface based on screenprinter.ppd will be created and used to get font information. You can modify the Fonts section of screenprinter.ppd to include new fonts, and modify the DefaultResolution field to change the resolution DefaultResolution is 96. The font look up algorithm on UNIX is: if a valid printer available then look up font information from the printer else create a screenPrinter surface look up font information from ScreenPrinter if ScreenPrinter creation fails then REP-1800 : Formatter Error if REPORTS_DEFAULT_DISPLAY is set else use Screen Fonts

10.8.2 Advanced Imaging Support

The quality of images contributes considerably to the overall appearance of a report, particularly for a Web report. You may prefer different image formats in your report output depending on the needs of your project. For example, an aeronautical firm might prefer the higher quality of JPEG or PNG images in their Web reports instead of GIF images. On the other hand, if you are building a Web portal, you might prefer GIF images because of their smaller size and faster download. Similarly, you may wish to import images of these various formats into your report. Depending on the format of your output, you may choose from a variety of formats for your images. Note: If you do add new fonts, ensure that the new AFM metrics files are placed in the AFM directory. Note: In certain multibyte languages like Chinese, you may want to use screen fonts. However, this would necessitate setting the DISPLAY variable for running the report. To revert to DISPLAY and use screen fonts old font look up algorithm: ■ Set REPORTS_DEFAULT_DISPLAY=NO ■ Remove the screenprinter.ppd entry in the uiscreenprint.txt file.
