v-card-media with base64 image

I am creating a captcha image in ColdFusion and returning it as a REST feed with Taffy. It is then shown in Vuetify

ColdFusion / Taffy code

<cfscript>
  component extends="taffy.core.resource" taffy_uri="/captcha" {

  function get() hint="Sends one out" {

  var captcha   = CreateUUID().right(4) & DayOfWeekAsString(DayOfWeek(now())).left(1).lcase() & "!";

  // This is ColdFusion
  var tempFile = "ram:///#captcha#.txt";

  var myImage = ImageCreateCaptcha(100, 300, captcha, "low");

  ImageWriteBase64(myImage, tempFile, "png", true, true);

  var myfile = FileRead(tempFile);
  FileDelete(tempFile);


  return rep({'status' : 'success', 'time' : GetHttpTimeString(now()),
    'captcha_hash' : hash(captcha), 'captcha_image' : myFile
    });
}
...
</cfscript>

It returns something like this:

{"status":"success","captcha_image":"data:image/png;base64,iVBORw0KG /d67W8EALALKJQAABBYAAAILABAYAEAILAAdr...

Vue

I can display the image via

<img :src="captcha_image" height="100px;">

Vuetify

If I don't use a height, the image does not come out at all

If I use a height like this, it comes out with the wrong aspect ratio.

<v-card-media :src="captcha_image" height="100px"></v-card-media>

Is there a work around? Or is <v-card-media the wrong tool for this?

The reason is that v-card-media use the image as a background image of a div with fixed height.

If you want to keep the aspect ratio. You can use <img /> tag with a width="100%" instead.

<img src="data:image/jpeg;base64,/9j/4AAQ..." width="100%">
