In order to create a text overlay, you can either pre-define a text style by your preference (e.g., font family, size, color, and more), or dynamically define one.
Pre-defining a text style:
You can create a text style by your choice of font family, size, color and many more parameters.
Fore more information:
http://cloudinary.com/documentation/upload_images#text_layers
Text styles can be generated via the API with our integration libraries as well. For example in PHP:
\Cloudinary\Uploader::text("Sample Name",
array(
"public_id" => "dark_name",
"font_family" => "Arial", "font_size" => 12,
"font_color" => "black", "opacity" => 90));
After the text style has been created, any custom text string can be generated as a text overlay:

Also, you can dynamically change the font's color:

Dynamically generate a text style:
You can generate a text style by your requirements on-the-fly, including font family, size, decoration and more.
Here's an example of a URL with an on-the-fly generated text style:
http://res.cloudinary.com/demo/image/upload/w_200,o_30/l_text:Arial_35_bold:Hello%20World/sample.jpg
You can also set the color parameter (co in URLs) to dynamically color the font to your required color:

This is super helpful. Is there a way to do add a images and a text one below the other? So, an image, then some text and then another image below it and so on?
Hi Raj,
Were you referring to something similar to the following?:
http://res.cloudinary.com/demo/image/upload/w_200/l_text:Arial_20_bold:My%20text,y_-25,g_south/l_sample,g_south,w_200,y_-140/sample.jpg
If so, you can have a look at the following for more information about text custom positioning:

Can you please share the URL generated by this code so we'll be able to further understand the issue?
For the web browser URL code to enable overlay text that use Google Fonts with text outline or text shadow, go here: http://cloudinary.com/cookbook/add_a_text_to_an_image
Hope this helps!
Hi there. In the angular 2 api, is it possible to add the overlay text dynamically? I tried with interpolation (as per code snippet below) but I get "Unhandled Promise rejection: Template parse errors: Can't bind to 'overlay' since it isn't a known property of 'cl-transformation'."
This is what generates the error:
`<cl-transformation overlay = "text:Verdana_75_bold_underline_letter_spacing_14:'{{myText}}'"></cl-transformation>`
Hi @Siphiwe. Please use attribute binding, such as:
<cl-transformation attr.overlay="text:Verdana_75_bold_underline_letter_spacing_14:{{myText}}"></cl-transformation>
See example here - https://plnkr.co/edit/z5rnRI?p=preview
Thank you @Roee. That sorted me out
