cfclient.camera.getPicture

Note: The image quality of pictures taken using the camera on newer devices is quite good, and images from the Photo Album will not be downscaled to a lower quality, even if a quality parameter is specified. Encoding such images using Base64 can cause memory issues on many newer devices. Therefore, using FILE_URI for images captured is highly recommended.

Getting the image from the camera

By invoking the default camera application on the device, this function takes a photo using the camera as the source.

The following example shows how you can get an image from the camera using the getPicture function:

<cfset picture = cfclient.camera.getPicture(options, base64)>

The following example depicts the usage:

<cfclientsettings enableDeviceAPI=true>
<cfclient>
<cffunction access="public" name="getpiccam" returntype="void" >
<cfset opt = cfclient.camera.getOptions()>
<cfset response = cfclient.camera.getPicture(opt,true)>

<cfset response ='data:image/jpeg;base64,'+ response>
<cfset src_to_img("myimg", response)>
</cffunction>

</cfclient>

<button style="width:100;height:50" onclick="invokeCFClientFunction(' getpiccam',null)">Get a picture
</button>

<img style = "width:200; height:100;" id = "myimg"></img>

<script type="text/javascript">
function src_to_img(img_id,data_to_write)
{
document.getElementById(img_id).src=data_to_write;
}
</script>

In the above example, on the click of a button, the default camera application is opened and after capturing an image, the image is rendered in the <img> tag.

Note: If you pass true as a param indicating that the returned object should be a Base-64 encoded string, its content has to be prefixed with  “data:image/jpeg;base64,” before rendering it.
