Adding an Image to a Report

How to:

Reference:

With a StyleSheet you can add and position an image in a report. An image, such as a logo, gives corporate identity to a report, or provides visual appeal. You can add more than one image by creating multiple declarations.

You can also add an image as background to a report. A background image is tiled or repeated, covering the entire area on which the report displays. An image attached to an entire report, or an image in a heading or footing, can appear with a background image.

Images must exist in a file format your browser supports, such as GIF (Graphic Interchange Format) or JPEG (Joint Photographic Experts Group). PDF and PostScript reports support GIF and JPEG, as well as those SVG files that are created by the WebFOCUS graph engine.

For PDF, HTML, and DHTML output against data sources that support the Binary Large Object (BLOB) data type (Microsoft SQL Server, DB2, Oracle, Informix, and PostgreSQL, using its BYTEA data type), an image can be stored in a BLOB field in the data source.

The image must reside on the WebFOCUS Reporting Server in a directory named on EDAPATH or APPPATH. If the file is not on the search path, supply the full path name.

Reference: Browser and Device Support for Images in HTML Documents

Support for presenting images and graphs in HTML and DHTML compound reports is provided using an image embedding facility based on the client browser. Output generated by Internet Explorer browsers or in scenarios where the browser is unknown (such as when the report is distributed by ReportCaster) support image inclusion through the creation of a web archive file (.mht). For all other browsers, images are 64-bit encoded within the generated .htm file.

SET HTMEMBEDIMG is the command designed to ensure that all WebFOCUS reports can be accessed from any browser or device. By default, it is set to AUTO which determines which encoding algorithm to use based on the browser of the client machine that submits the report request. Where the browser is identified as an Internet Explorer browser, or the browser is unknown (such as reports distributed by ReportCaster), WebFOCUS will continue to generate Web Archive files (.mht). For all other browsers, WebFOCUS will encode the image into an HTML file (.htm).

SET HTMLEMBEDIMG={OFF|ON|AUTO}

where:

OFF

Does not affect the default behavior. If HTMLARCHIVE is set ON, .mht files are generated.

ON

Encodes images within the .htm file.

AUTO

Determines how to handle images based on the browser from which the request was submitted. For requests submitted from an Internet Explorer browser, HTMLARCHIVE will be used to embed the images into an .mht file. For all other browsers, HTMLEMBEDIMG will encode the image information into an .htm file. If the browser is unknown, as in report requests submitted by ReportCaster, AUTO will use the HTMLARCHIVE setting that is in effect. AUTO is the default value.

The encoding algorithm that uses 64-bit encoding supported for images less than 32K in size is supported by Internet Explorer 8. For Internet Explorer 8, Information Builders recommends continuing to use the .mht format generated by HTMLARCHIVE. In Internet Explorer 9 and higher and browsers other than Internet Explorer, the new algorithm is supported for images of any size.

Note: See the browser vendor information to confirm 64-bit encoding support.

To provide support for multiple browsers, Information Builders recommends using the AUTO setting to allow the appropriate type of file to be generated based on the user configuration, where it is known. The following table represents how HTMLEMBEDIMG interacts with HTMLARCHIVE across multiple browsers.

Syntax: How to Add an Image to an HTML Report

This syntax applies to an HTML report. For details on adding an image to a PDF, PS, or HTML report with an internal CSS, see How to Add an Image to a PDF, PS, or HTML Report With an Internal Cascading Style Sheet.

TYPE={REPORT|heading}, IMAGE={url|(column)} [,IMAGEALIGN=position]
     [,IMAGEBREAK={ON|OFF}] [,ALT='description'], $

where:

REPORT

Embeds an image in the body of a report. REPORT is the default value.

Note: The IMAGE=(column) option is not supported with TYPE=REPORT.

heading

Embeds an image in a heading or footing. Valid values are TABHEADING, TABFOOTING, HEADING, FOOTING, SUBHEAD, and SUBFOOT.

url

Is the URL for the image file. The image must exist in a separate file in a format that your browser supports, such as GIF or JPEG. The file can be on your local web server, or on any server accessible from your network. For details, see Specifying a URL.

column

Is an alphanumeric field in a request (for example, a display field or a BY field) whose value is a URL that points to an image file. Specify a value using the COLUMN attribute described in Identifying a Report Component in a WebFOCUS StyleSheet. Enclose column in parentheses.

This option enables you to add different images to a heading or footing, depending on the value of the field. See Using a File Name in a Data Source Field in an HTML Report.

IMAGEALIGN = position

Is the position of the image.

Note: IMAGEALIGN is not supported with HTMLCSS=ON. With HTMLCSS=ON, you can position images within a heading or footing by using the POSITION attribute to specify a position relative to the upper-left corner of the heading or footing. For more information about the POSITION attribute, see How to Add an Image From a BLOB Field to a PDF, DHTML, or HTML Report.

Valid values are:

TOP where the top right corner of the image aligns with heading or footing text. If the image is attached to the entire report, it appears on top of the report.

MIDDLE where the image appears in the middle of the heading or footing text. If the image is attached to the entire report, it appears in the middle of the report.

BOTTOM where the bottom right corner of the image aligns with heading or footing text. If the image is attached to the entire report, it appears at the bottom of the report.

LEFT where the image appears to the left of heading or footing text. If the image is attached to the entire report, it appears to the left of the report.

RIGHT where the image appears to the right of heading or footing text. If the image is attached to the entire report, it appears to the right of the report.

IMAGEBREAK

Controls generation of a line break after the image. Valid values are:

ON which generates a line break after the image so that an element following it (such as, report heading text) appears on the next line.

OFF which suppresses a line break after the image so that an element following it is on the same line. OFF is the default value.

description

Is a textual description of an image for compliance with Section 508 accessibility. Enclose the description in single quotation marks.

The description also displays as a pop-up description when your mouse or cursor hovers over the image in the report output.

Syntax: How to Add an Image to a PDF, PS, or HTML Report With an Internal Cascading Style Sheet

This syntax applies to a PDF, PS, or HTML report with an internal cascading style sheet. The image can be in a separate file.

A report with an Internal cascading style sheet is an HTML page with an HTML cascading style sheet (CSS) stored between the style tags within the HTML document.

TYPE={REPORT|heading}, IMAGE={url|file|(column)} [,BY=byfield]
[,POSITION=([+|-]x [+|-]y )] [,SIZE=(w h)] ,$

where:

REPORT

Embeds an image in the body of a report. The image appears in the background of the report. REPORT is the default value.

heading

Embeds an image in a heading or footing. Valid values are TABHEADING, TABFOOTING, FOOTING, HEADING, SUBHEAD, and SUBFOOT.

Provide sufficient blank space in the heading or footing so that the image does not overlap the heading or footing text. Also, you may want to place heading or footing text to the right of the image using spot markers or the POSITION attribute in the StyleSheet.

url

HTML report with internal cascading style sheet:

Is the absolute or relative address for the image file. The image must exist in a separate file in a format that your browser supports, such as GIF or JPEG. The file can be on your local web server, or on any server accessible from your network. For details, see Specifying a URL.

file

PDF or PS report:

Is the name of the image file. It must reside on the WebFOCUS Reporting Server in a directory named on EDAPATH or APPPATH. If the file is not on the search path, supply the full path name.

When specifying a GIF file, you can omit the file extension.

column

Is an alphanumeric field in the data source that contains the name of an image file. Use the COLUMN attribute described in Identifying a Report Component in a WebFOCUS StyleSheet. Enclose column in parentheses.

The field containing the file name or image must be a display field or BY field referenced in the request.

Note that the value of the field is interpreted exactly as if it were typed as the URL of the image in the StyleSheet. If you omit the suffix, .GIF is supplied by default. SET BASEURL can be useful for supplying the base URL of the images. If you do that, the value of the field does not have to include the complete URL.

This syntax is useful, for example, if you want to embed an image in a SUBHEAD, and you want a different image for each value of the BY field on which the SUBHEAD occurs. See Using a File Name in a Data Source Field in an HTML Report.

byfield

Is the sort field that generated the subhead or subfoot.

POSITION

Is the starting position of the image.

+|-

Measures the horizontal or vertical distance from the upper-left corner of the report component in which the image is embedded.

x

Is the horizontal starting position of the image from the upper-left corner of the physical report page, expressed in the unit of measurement specified by the UNITS parameter.

Enclose the x and y values in parentheses. Do not include a comma between them.

y

Is the vertical starting position of the image from the upper-left corner of the physical report page, expressed in the unit of measurement specified by the UNITS parameter.

SIZE

Is the size of the image. By default, an image is added at its original size.

w

Is the width of the image, expressed in the unit of measurement specified by the UNITS parameter.

Enclose the w and h values in parentheses. Do not include a comma between them.

h

Is the height of the image, expressed in the unit of measurement specified by the UNITS parameter.



Example: Adding a GIF Image to an HTML Report With Internal Cascading Style Sheet

A URL locates the image file GOTHAM.GIF on a server named WEBSRVR1. The TYPE attribute adds the image to the report heading. POSITION places the image one-quarter inch horizontally and one-tenth inch vertically from the upper-left corner of the report page. The image is one inch wide and one inch high as specified by SIZE.

Syntax: How to Add an Image From a BLOB Field to a PDF, DHTML, or HTML Report

For PDF, HTML, and DHTML output against data sources that support the Binary Large Object (BLOB) data type (Microsoft SQL Server, DB2, Oracle, Informix, and PostgreSQL using its BYTEA data type), an image can be stored in a BLOB field in the data source.

WebFOCUS StyleSheets used to produce report output in PDF, HTML, or DHTML format can access a BLOB field as an image source when an instance of the BLOB field contains an exact binary copy of a GIF or JPEG image. HTML and DHTML reports also support PNG images. Images of different formats (GIF, JPEG, PNG) can be mixed within the same BLOB field. WebFOCUS can determine the format from the header of the image. The image can be inserted in report columns, headings, footings, subheadings, and subfootings.

The BLOB field must be referenced in a PRINT or LIST command in the request (aggregation is not supported). Reports containing BLOB images are supported as components in Coordinated Compound Reports.

With the following SET commands, BLOB images will work for both HTML and DHTML in all browsers:

TYPE={REPORT|heading}, IMAGE={url|file|(column)} [,BY=byfield]
[,POSITION=([+|-]x [+|-]y )] [,SIZE=(w h)] [,PRESERVERATIO={ON|OFF}],$
TYPE=DATA, COLUMN=imagefield, IMAGE=(imagefield), SIZE=(wh)
[,PRESERVERATIO={ON|OFF}] ,$

where:

REPORT

Embeds an image in the body of a report. The image appears in the background of the report. REPORT is the default value (not supported for images stored in BLOB fields, which are supported for PDF output).

heading

Embeds an image in a heading or footing. Valid values are FOOTING, HEADING, SUBHEAD, and SUBFOOT.

If the image is to be embedded in a heading, subheading, footing, or subfooting rather than a column, the StyleSheet declaration is responsible for placing the image in the heading, subheading, footing, or subfooting. To make the BLOB image accessible to the StyleSheet, the BLOB field must be referenced in the PRINT or LIST command with the NOPRINT option. Do not reference the BLOB field name in the heading or footing itself.

Provide sufficient blank space in the heading or footing so that the image does not overlap the heading or footing text. Also, you may want to place heading or footing text to the right of the image using spot markers or the POSITION attribute in the StyleSheet.

file

Is the name of the image file. It must reside on the WebFOCUS Reporting Server in a directory named on EDAPATH or APPPATH. If the file is not on the search path, supply the full path name.

When specifying a GIF file, you can omit the file extension.

column

Is a BLOB field in the data source that contains an exact binary copy of a GIF or JPEG image. HTML and DHTML formats also support images in PNG format. Images of different formats (GIF, JPEG, PNG) can be mixed within the same BLOB field. WebFOCUS can determine the format from the header of the image. The image can be inserted in report columns, headings, footings, subheadings and subfootings. Use the COLUMN attribute described in Identifying a Report Component in a WebFOCUS StyleSheet. Enclose column in parentheses.

The field containing the file name or image must be a display field or BY field referenced in the request.

byfield

Is the sort field that generated the subhead or subfoot.

imagefield

Is any valid column reference for the BLOB field that contains the image. Note that the BLOB field must be referenced in a PRINT or LIST command in the request.

If omitted, the default size is 1 inch by 1 inch. The width of the column and the spacing between the lines is automatically adjusted to accommodate the image.

POSITION

Is the starting position of the image.

+|-

Measures the horizontal or vertical distance from the upper-left corner of the report component in which the image is embedded.

x

Is the horizontal starting position of the image from the upper-left corner of the physical report page, expressed in the unit of measurement specified by the UNITS parameter.

Enclose the x and y values in parentheses. Do not include a comma between them.

y

Is the vertical starting position of the image from the upper-left corner of the physical report page, expressed in the unit of measurement specified by the UNITS parameter.

SIZE

Is the size of the image. By default, an image is added at its original size. Note that images stored in BLOB fields are supported only for PDF, HTML, and DHTML output.

w

Is the width of the image, expressed in the unit of measurement specified by the UNITS parameter.

Enclose the w and h values in parentheses. Do not include a comma between them.

h

Is the height of the image, expressed in the unit of measurement specified by the UNITS parameter.

If SIZE is omitted, the original dimensions of the image are used (any GIF, JPEG, or PNG image has an original, unscaled size based on the dimensions of its bitmap).

[PRESERVERATIO={ON|OFF}]

Not supported for images in PNG format. PRESERVERATIO=ON specifies that the aspect ratio (ratio of height to width) of the image should be preserved when it is scaled to the specified SIZE. This avoids distorting the appearance of the image. The image is scaled to the largest size possible within the bounds specified by SIZE for which the aspect ratio can be maintained. Supported for PDF and PS output. OFF does not maintain the aspect ratio. OFF is the default value.

The actual size of an image stored in a BLOB field may vary from image to image, and scaling the images to a designated size allows them to better fit into a columnar report. Note: Images stored in a BLOB field are supported only for PDF, HTML, and DHTML output.



Example: Inserting an Image From a BLOB Field Into a Report Column

The Microsoft SQL Server data source named retaildetail contains product information for a sports clothing and shoe retailer. The Microsoft SQL Server data source named retailimage has the same product ID field as retaildetail and has an image of each product stored in a field named prodimage whose data type is BLOB.

Example: Sizing an Image From a BLOB Field

The Microsoft SQL Server data source named retaildetail contains product information for a sports clothing and shoe retailer. The Microsoft SQL Server data source named retailimage has the same product ID field as retaildetail and has an image of each product stored in a field named prodimage whose data type is BLOB.

The following request joins the two data sources and displays the same image on three columns of output using different sizes and different PRESERVERATIO settings. Note that PRESERVERATIO=ON is not supported with images in PNG format.

The output is generated in DHTML format. It can also be generated in HTML or PDF format.

TYPE=DATA,COLUMN=P3,IMAGE=(PRODIMAGE),SIZE=(.75 1),PRESERVERATIO=OFF,$
END

Note that PRESERVERATIO=OFF is specified for the second column to preserve the image height and width ratio for that column even though the styling SIZE height specifies a different value than the first column image styling. In addition, PRESERVERATIO=OFF is specified for the third column, so for that column the image height to width ratio is not preserved and is rendered as specified by the styling SIZE height and width values specified in the request (FEX).

Example: Inserting an Image From a BLOB Field in a Summary Report

In order to insert an image from a BLOB field in a report that displays summary data, you must include two display commands in the request, a SUM command for the summary information and a PRINT or LIST command for displaying the image and any other detail data.

The Microsoft SQL Server data source named retaildetail contains product information for a sports clothing and shoe retailer. The Microsoft SQL Server data source named retailimage has the same product ID field as retaildetail and has an image of each product stored in a field named prodimage whose data type is BLOB.

The following request joins the two data sources. It contains two display commands, a SUM command and a PRINT command. The SUM command aggregates the total price for each category and displays this category name and total price in a subheading, The PRINT command displays the image for each item in the category along with its individual product number and price in a subfooting.

The output is generated in DHTML format. It can also be generated in HTML or PDF format.

Reference: File Size and Compression Considerations For Images in BLOB Fields

The actual size of an image stored in the BLOB field may vary from image to image, and scaling the images to a designated size allows them to better fit into a columnar report.

Files that contain many images can be large. Scaling the images to a smaller size using the SIZE attribute does not decrease the size of the file. Note also that using SET FILECOMPRESS=ON will not reduce the size of images in a PDF file, since images are already saved in compressed form.
