4d Form Screenshot

Capture a PNG screenshot of a specific 4D form from the current project. Use this skill when the user wants a preview image for a form name or a form.4DForm path. Copies assets/_formScreenshot.4dm into the project if missing, passes the form input through --user-param, and retries after copying assets/defaultJsonForm.json into the runtime Resources folder when that file is missing.

4D Form Screenshot

Capture a screenshot for a specific form and save it as Project/Sources/Forms/<FormName>/form.png.

Inputs

Accept either:

A form name such as Form1
A path to form.4DForm such as Project/Sources/Forms/Form1/form.4DForm
A path to the form folder if that folder contains form.4DForm

Optionally append : followed by a page number to capture a specific page (e.g. Form1:2). Page 0 is the shared page. If omitted, page 1 is used by default.

Pass the raw form input through --user-param. The bundled _formScreenshot.4dm resolves a form.4DForm path to the form name and parses the optional page number before calling FORM SCREENSHOT.

Use /4d-run

Use the /4d-run skill to locate tool4d and to run the startup method.

Workflow

Locate the current .4DProject.
Copy assets/_formScreenshot.4dm to Project/Sources/Methods/_formScreenshot.4dm if it is missing.
Keep the user input unchanged and pass it as --user-param=<form name or path> (append :<page> when a specific page is requested, e.g. --user-param=Form1:2).
Use /4d-run to run _formScreenshot on the current project.
Prefer tool4d first. If /4d-run needs the full 4D runtime, use the user-provided 4D executable path through /4d-run.
If the run crashes because defaultJsonForm.json is missing, copy assets/defaultJsonForm.json into the Resources folder of the runtime being used, then retry.
Return the generated screenshot path: Project/Sources/Forms/<FormName>/form.png.

Missing defaultJsonForm.json

Some runtimes crash on FORM SCREENSHOT when defaultJsonForm.json is missing.

When that happens:

If /4d-run is using tool4d.app, copy the bundled assets/defaultJsonForm.json to tool4d.app/Contents/Resources/defaultJsonForm.json
Retry the same _formScreenshot run afterward
