loading image svg via url

Hi,

With an image I try to load a svg via an url dynamically. If I use an url with an extension like "http://demo.com/picture.svg" it does work. However, for the reports I'm making I need up to 200 svg images, I do not like to make and save all these files. What I want is to generate the svg images on the fly.

Problem : an url like "http://demo.com/picture/100" or "http://demo.com/picture.php?pic=100" does not work! It seems that the image uri checks on the extension "svg".

Any ideas how to fix this?

Thanks,
Herbert

Can you try something like this on the onCreate for the image?

importPackage(Packages.java.io);
importPackage(Packages.java.lang);

var file = new File("c:/temp/test.svg");
var ist = new FileInputStream(file);
var lengthi = file.length();

bytesa = new ByteArrayOutputStream( lengthi);
var c;
while((c=ist.read()) != -1){
bytesa.write(c);
}
ist.close();
this.data = bytesa.toByteArray();

Hi,

I can use your solution for now, but ideally I would like to have a webapp that dynamically generate the svg images, these svg's must also be used in other applications.

Alternatively : Is there a way to modify a "static" svg image that is loaded via the resources? In a test I see the svg definition in a list-property if I view it as xml, but the data is compressed or base-64? How can I clone this data and modify the svg?

thanks,
Herbert.

Herbert,

You should be able to modify the code I posted to read from a url instead of a file.

The embedded images are base64 encoded, but that is probably not your best solution. You should be able to put muliple svg images in your resource folder and swap them on the fly. This will require that your code generate the images in the resource folder(configurable in web.xml) though.
