Images rendered 4/3 larger than reality

2006-03-04 05:02

iReports 1.2.0

 

I have a report with an image, set to RetainShape.

 

However when I render to JRViewer or PDF the images look exactly 4/3 larger, and hence jaggy.

 

Why is this?

 

I can replicate this by creating a new document, plopping in an image, setting to retain shape and setting the size, i.e. very very simply.

 

Here is the xml of the report

 

<?xml version="1.0" encoding="UTF-8" ?>

I told ireports that the image was 75% smaller than it actually is, and now it looks good!

 

Where does this weirdness come from?

Hi!

 

I have the same problem with my images. I have to insert a logo in my reports and they appear at 4/3 of their real size too!

You can see this effect in the image examples of jasper:

http://jasperreports.sourceforge.net/samples/ImagesReport.html

the real image:http://jasperreports.sourceforge.net/jasperreports.png

 

I tried the solution you chose, putting them at 3/4 of the size just to make them have their real size inside the reports (4/3*3/4 = 1 ;)).

 

BUT! with this approach, the logo is out of focus! Haven´t you noticed this? Anyone can help me with this? The logo is not well shown, and the client is complaining!

 

Thanks in advance for all your help!

Use the option clip instead of retain shape. Clip will maintein the exacly dimension of the image.

For more information look on the manual of Ireport.

Hi!

 

thansk for the reply, but that is not the answer.

 

If you take a look at the example:

 

http://jasperreports.sourceforge.net/samples/ImagesReport.html

 

you will notice it is this code:

Code:

<image scaleImage="Clip" onErrorType="Icon" isLazy="true"><reportElement x="0" y="0" width="150" height="40"/><imageExpression class="java.lang.String">"http://jasperreports.sourceforge.net/jasperreports.png"</imageExpression></image>

 

It is already "Clip", but the size is not the real one of the image, but 4/3 of it.

 

I think this may be a bug, but I have not found anyone with this problem but this post!

 

Don´t you use images in your reports?

 

Thanks again.

I'm experiencing this problem as well. It seems a strange bug to have been in the jasper for so long. Has there been any official response?
