Get SVG text from database and show as Image

[White Sorrow]

Hi , I have stored the svg text to the database and need to show as Image(have method to convert to bitmap or base64) on preview page by automatic determine is this field is xml text or not

which parts of source code that get data from db and show to the preview? 

and if I show text as Image on preview is there can export and can see the image on export file?

or maybe the another way to show svg text as Image automatically no not do anything with RDL file?

Thanks

As far as I know, RDL specification didn't support SVG. I think we didn't support it too.
But you can implement support svg as image type in any case.

About export image. This is absolutely depends on render used for export. For example, current render for Excel didn't support export any image.

I had add the class for convert SVG text to image already , but what I need is how could I change the preview process that I can check if VALUE from database is xml text and I can choose to show value as Image

example:

field name in db is image
for normally table value is =Fields!image.Value 
and when I go to preview tab this cell query value from database then check before render the page

if(xml type?){

   convert context to image as base64 or bitmap

}else{

   show normal text

}

Thanks

Perhaps, I didn't understand you question or i didn't understand what you do.
I think Majorsilence Reporting will not automatically detect that field is svg or is not. I think user need say that this is svg, like user did it for jpeg and another image types.

If you say about table, you need replace cell from text to image.

This is what I need to do

I need to change some of source code of ReportDesigner when ReportDesigner have a table or anything else that need to query the value from database

In this query when ReportDesigner get data from the database I can add my source code to decide is it xml or not(this I have method to do)

But the problem is I don't know which cs file,method that do this process , So I can't add my source code to it.

or maybe cs file/method that render the ReportPreviewPage so I can force it to show image instead of text

Thanks for reply

I have solved this

This is what I do:

at the RdlEngine project in the definition/Image.cs at GetImageStream method I have check if the value is xml string then convert to svg -> draw to bitmap -> convert to byte[] then use normally.

this will convert the xml string to image byte and show at preview page

** User need to replace textbox with image by manual (can be automatic replace by check column name,but it will exclusive for specify project only)

Thanks
