Hi Fam
If you are using PDF-Lib to create and update PDF documents, you will find this very invaluable, especially when you have to edit existing pdf documents. Open your pdf document and mouse over or click to find the co-ordinates. For PDF-Lib (0,0) is at bottom left.
Why...
In the realm of PDF document manipulation, precision is paramount. Whether you're automating form filling, overlaying text, or placing images, achieving exact placement within a PDF requires accurate coordinate mapping. The PDF-Lib Pointer tool addresses this need by providing a visual interface to identify precise coordinates, which can then be utilized in code to position elements accurately.
PDF-Lib utilizes a coordinate system where the origin (0,0) is typically at the bottom-left corner of the page. This system can be counterintuitive, especially when integrating with other coordinate systems where the origin might be at the top-left. Tools like PDF-Lib allow developers to draw text, images, and shapes at specific coordinates within a PDF document. pdf-lib.js.org
Manually determining the exact coordinates for placing elements in a PDF can be cumbersome. Without a visual reference, developers often resort to trial and error, leading to inefficiencies and potential inaccuracies. This is where the PDF-Lib Pointer tool comes into play.
The PDF-Lib Pointer tool offers a user-friendly interface that overlays a coordinate grid onto a PDF document. By interacting with this interface, developers can:
This pointing sytem you then use when executing code like..
Without having to guess but knowing exactly where.
Enjoy!
PS: I was updating existing PDF contracts when I needed something like this and using PDF-Lib on my code.

- Identify Exact Coordinates: Hovering over or clicking on the PDF displays the precise x and y coordinates.
- Align Elements Accurately: By knowing the exact coordinates, developers can position text, images, and other elements with pixel-perfect accuracy.
- Integrate with Code: The identified coordinates can be directly used in code to place elements at the desired locations within the PDF.

page.drawText('Saturn IV', { x: 120, y: 500, size: 18 })
page.drawText('Delta IV Heavy', { x: 340, y: 560, size: 18 })
page.drawText('Space Launch System', { x: 340, y: 500, size: 18 })Without having to guess but knowing exactly where.
