Displaying Images on Visualforce pages using Base64 Blob












2















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?






apex visualforce images base64

          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.
