Displaying Images on Visualforce pages using Base64 Blob
My question is about displaying base64 blob as image in visualforce page. Here's my controller code:
Object img;
public Object getImg () {
List<ContentVersion> bodyList = [SELECT VersionData FROM ContentVersion WHERE ContentDocumentId='the real id'];
img = bodyList[0].get('VersionData');
return img;
}
Here's the visualforce:
<img src="data:image/png;base64,{! img }"/>
This is getting rendered as
<img src="data:image/png;base64,core.filemanager.FileBlobValue@1e76577f">
How can I get the actual base64 of image so the image is displayed properly?

Figured it out after debugging a bit more.
Blob img;
public Object getImg () {
List<ContentVersion> bodyList = [SELECT VersionData FROM ContentVersion WHERE ContentDocumentId='insert your id'];
img = (Blob) bodyList[0].get('VersionData');
return EncodingUtil.base64Encode(img);
}
All I had to do was to typecast the Object as Blob and then encode the blob value.
