## Description
19+
20+
This article shows how to draw rectangles with formatted text or image content with the [FixedContentEditor]({%slug radpdfprocessing-editing-fixedcontenteditor%}) in the [PdfProcessing]({%slug radpdfprocessing-overview%}) library.
21+
22+
This knowledge base article also answers the following questions:
23+
- How can I draw a rectangle and style it using RadPdfProcessing?
24+
- How to add centered text within a rectangle in a PDF document?
25+
- How to insert an image and center it within a rectangle using RadPdfProcessing?
26+
27+
## Solution
28+
29+
To draw a rectangle with a black stroke and a light blue background, add centered text, and insert a centered image within the rectangle using the RadPdfProcessing library, follow these steps:
30+
31+
1. Draw a rectangle by creating a [Path]({%slug radpdfprocessing-model-path%}) with a [RectangleGeometry]({%slug radpdfprocessing-concepts-geometry%}#rectanglegeometry), defining its dimensions, formatting it, and inserting it in the page.
32+
2. Create a **Block** of text, format it, and draw it on top of the rectangle with the **FixedContentEditor** by specifying its **Position**.
33+
3. Draw a second rectangle at a different position.
34+
4. Create an image **Block** and draw it on top of the second rectangle with the **FixedContentEditor** while specifying its **Position**.
35+
5. Export the **RadFixedDocument** to PDF.
