![]() Since it uses the Eclipse environment in order to organize all the necessary resources, you are able to create projects that contain styles, libraries and images needed for report development. ![]() It helps you to quickly create interesting and full-detailed layouts with embedded charts, images and crosstabs, to name a few, then publish your reports to PDF, XML, RTF, CSV, HTML or DOCX format. Below the last line that starts with and above the line, add this line: Īll done! Save and preview your report, and you’ll see the image included in the report.Being a full rewrite of iReport Designer, available as an Eclipse plugin, as well as a standalone application, Jaspersoft Studio is a comprehensive and reliable piece of software especially designed for JasperReports and JasperReports Server. In the report editor there are tabs for “Design”, “Source”, and “Preview”. One final step…in order to use the codeBase64 function when the report is run, we need to explicitly import that class when the report is run. getBytes ())) Step 4: Add Base64 class import to the report There is a place in the snippet where the variable with the base64-encoded image is included (CSpaceLogo in this case) replace this with the variable name from the previous step.new ByteArrayInputStream(codeBase64($V. Pick the last choice, “Custom expression”, and enter this snippet of Java below. A “Create new image element” dialog box pops up with several choices for “Image creation mode”, including a workspace resource, an absolute path, or a URL. Click and drag an image element from the Palette onto the report. Leave all of the other values the same (Value Class Name is, no calculation function or increment type, reset type is Report, and no data in Initial Value Expression or Incrementer Factory Class Name).Step 3: Add image to the report Select "Custom expression" and paste Java snippet. Give the variable a name and paste the image data into the Expressions field surrounded by double quotes. Give the variable a name and paste the image data into the Expressions field in quotes. Right click (or control click) on the “Variables” heading in the Outline view, and select “Create Variable”. ![]() To put the image data into the JRXML file, we will create a variable in the report. The remainder of the string is the base64-encoded image data.Step 2: Put the base64 image data into a report variable In the Outline, right click on Variables to create a variable. Everything up to and including the comma – data:image/jpeg base64, – needs to be removed. What you will get back is a string of data that starts like this:data:image/jpeg base64,/9j/4AAQSkZJRgABAQEAY.This is a DATA URI, and it contains details at the start that are not part of the image data itself. There are many ways to do the encoding I use the Base64 Image Encoder site. XML files have limits on what they can contain, so encoding the binary image file in base64 provides a way to embed the image data into XML while still honoring the ASCII nature of XML. The instructions below are correct for Jaspersoft Studio version 6.2.0.Step 1: Encode your image in base64Base64 is a way to take a binary file and encode it into ASCII characters. This is possible, but the instructions and hints you find out on the internet to do it are out of date or incomplete. The JRXML files must be compiled into the application, which makes keeping track of the ancillary graphics files somewhat troublesome.Ideally, I would like to embed the graphics into the JRXML file itself, similar to what is done in with the data URI schema in HTML and CSS files to reduce the connection latency between client and server. In the environment that I’m working in, CollectionSpace, the report generator is embedded in the application without the JasperReports Server endpoint. Most times the configuration file and the ancillary graphics files are uploaded to a JasperReports Server for execution. These graphic files are normally listed in the JRXML configuration file by reference – meaning that what is stored in the configuration is a file name and not the graphic itself. One of the features of Jaspersoft Reports is the ability to include static graphics – logos, for instance – in the completed reports. ![]() These list items are microformat entries and are hidden from view. ![]()
