About images Layout Objects

Advanced Concepts 2-27 3. Summaries that are owned by the report, not by a group, are allowed in all report layout styles. They are all formatted in the following way: ■ If the layout style is form-like, form letter, or mailing label, the summary is a report column. A report column is formatted like any other database column for that report style. ■ If the layout style is tabular, group leftabove, or matrix, and the column on which the summary performs its function is not selected, the summary is a report column. It is formatted as stated in the bullet above. Otherwise, the summary is a report summary. It is formatted left-justified at the end of the report, with the label to the left of the field if there is room. 4. If the layout style is tabular, group leftabove, or matrix, a summary is defaulted like a database column if the column it summarizes is not selected. Otherwise, a summary is defaulted like summaries that is, appearing inside the M_groupname_ FTR frames. 5. If the layout style is tabular, group leftabove, or matrix, Oracle Reports Builder places one summary type per line, in the following order: ■ SUM ■ AVERAGE ■ MINIMUM ■ MAXIMUM ■ COUNT ■ FIRST ■ LAST ■ OF TOTAL ■ STANDARD DEVIATION ■ VARIANCE 6. If the layout style is tabular, group leftabove, or matrix, the summary label will appear to the far-left of the group footer frame M_groupname_FTR. If there is not room for the full label, the label will be truncated. See also Section 4.5.4, Creating a default layout for a report Section 4.10.2, Creating a default layout for a section

2.4.3 About images

You can add an image to a report by: ■ Importing an image from a file into the report layout paper-based report only. See Section 4.9.8.1.1, Importing an image . Caution: For form letter and mailing label reports, the default for CHAR if you reduce the default width and LONG fields have a Horizontal Elasticity and Vertical Elasticity property setting of Fixed. As a result, the field value will be truncated if the size of the data is greater than the size of the field. 2-28 Oracle Reports Users Guide to Building Reports ■ Creating a file link object in the Paper Layout paper-based reports only. See: – Section 4.9.8.1.2, Linking an image object to a file – Section 4.9.8.1.3, Linking an image object to a URL for HTML and HTMLCSS output ■ Selecting a database column in a query both paper-based and JSP-based Web reports. See: – Section 4.8.5, Selecting an image from the database – Section 4.8.6, Selecting an image URL from the database for HTML output The first method using the Import Image dialog box provides for including images in the following formats: TIFF, JFIF, BMP, TGA, PCX, PICT, GIF, CALS, RAS, OIF, PCD. The other two methods creating a file link object, and selecting a column in the database provide for including additional formats supported by Oracle Reports, including JPEG all types, such as Progressive JPEG and Exif JPEG, PNG, BMP, TIFF, GIF, and CGM. By default, images display in fields so that they appear in the printed report, not only in the Previewer. Enhanced imaging support is provided by the REPORTS_OUTPUTIMAGEFORMAT environment variable and OUTPUTIMAGEFORMAT command line keyword. The enhancements in imaging support provide the capability to generate complex graphics-intensive reports with high fidelity image output. Additionally on UNIX, the dependency on a windowing system for displaying images is removed; the PostScript printer driver screenprinter.ppd provides surface resolution for images. You can include an unlimited number of image objects without running out of local disk space by using non-caching references. A non-caching reference causes objects to be read from the database only when needed while a report is processing. You must be connected to an ORACLE V7.1 or later database to use this feature. If you reference a URL for an image, the image is displayed when you format your report for HTML output. For other output formats, the URL text displays in the Paper Design view; in the output destination for example, a file or PDF document, nothing is displayed. It is your responsibility to verify that the URL exists; Oracle Reports Builder does not validate the existence of the resource nor the syntax of the protocol. The size of the object that contains the URL defines the size of the image in the HTML output. Any elasticity properties applied to the object are ignored. Limitations ■ If the input image includes more than 256 colors, and the output image format is set to GIF with the OUTPUTIMAGEFORMAT command line keyword or the REPORTS_OUTPUTIMAGEFORMAT environment variable, Oracle Reports implements a color reduction to 256 colors to successfully generate the GIF. ■ On UNIX, CGM format is not supported in HTML output. This limitation does not apply on the Windows platform.
