Is this a dumb question? [message #127150]

I searched bugzilla and I couldn't find any reference to this. I also
searched this newsgroup.

I'm trying to insert a java image (BufferedImage) into a Birt Report.
I'm using a scripted data set to retrieve the buffered image from a java
object and I am putting it into a Dynamic Image item with the expression
set to row["BAR_CODE_IMAGE"] in my report template.

When I run the report (from a within a java application) I get the
following error message :

Feb 9, 2006 10:37:50 AM
org.eclipse.birt.report.engine.layout.impl.ImageLayoutManage r layout
SEVERE: can't retrieve image intrinsic dimension!

So I put some system.out code inside of the ImageLayoutManager.java in
the "protected Dimension getIntrinsicDimension(IImageContent content)"
method and I recompiled the class. Here is the output :

>> Inside getIntrinsicDimension
>> content.getAltText() : null
>> content.getExtension() : null
>> content.getGenerateBy() :
org.eclipse.birt.report.engine.ir.ImageItemDesign@16fdac

>> content.getChildren() : []
>> content.getClass() : class >>

>> content.getData() : null
>> content.getHeight() : 62px
>> content.getInstanceID() : /240(QuRs368224148:0)

>> content.getReportContent() :
org.eclipse.birt.report.engine.content.impl.ReportContent@19fdbcb
>> content.getWidth() : 299px

When I switch the report element to be a URI with an expression of
row["BAR_CODE_IMAGE"] the call to content.getURI() returns
>>content.getURI() : BufferedImage@363068: type = 1 DirectColorModel:
rmask=ff0000 gmask=ff00 bmask=ff amask=0 IntegerInterleavedRaster: width
= 191 height = 35 #Bands = 3 xOff = 0 yOff = 0 dataOffset[0] 0

So I know that my row["BAR_CODE_IMAGE"] actually contains my buffered image.

Do I have something set up wrong? Are java images not supported yet in Birt?

Thank you for any help,
florin

I have the same problem like you, so we seems to be both dumb!
Any ideas to overcome this problem?

I have yet to find a solution for this. We couldn't have been the only
two people to try to use java images in reports. Maybe its a known
limitation but I haven't found any documentation stating that. If I find
a solution I'll be sure to post it.

I haven't tried this but one work around would be to to create the image
onto the hard drive in a temporary directory, then change the value of
the image field (using engine api's) to point to the location of the
image. I would then periodically delete all of the files in the temp
directory.

I tried to read the (.BMP) image directly from a BLOB column from the
(Oracle) database and this worked. So, I think the problem is perhaps
with the scripted datasource which returns this image not as binary data
but as a String.
