Claus Ibsen created CAMEL-26353:
-----------------------------------
Summary: camel-diagram - zoom levels for a route diagram image, as
in the diagram of the Camel CLI
Key: CAMEL-26353
URL: https://issues.apache.org/jira/browse/CAMEL-26353
Project: Camel
Issue Type: Improvement
Components: camel-jbang, camel-diagram
Reporter: Claus Ibsen
Fix For: 4.24.0
The PNG of a route diagram (camel cmd route-diagram, the
camel_render_route_diagram MCP tool, the route-diagram developer console with
format=png) draws each step as a card with an icon, its kind and its detail
(CAMEL-26348). A card is taller than the old box, so a large route makes a tall
image, and it reaches the size limit of an image (16384 pixels) sooner, where
the command says to narrow the routes with --filter.
The diagram of the Camel CLI in the terminal (camel tui, the Diagram tab) has
zoom levels for this, see "Zoom and Folding" in
docs/user-manual/modules/ROOT/pages/camel-jbang-tui-diagram.adoc, and
RouteDensity / RouteDiagramZoom in camel-jbang-plugin-tui:
* detailed: a box per step, with up to three lines of text
* compact: a box per step with one line of text, the steps closer together
(about twice as many steps fit)
* bare: no boxes, each step a mark and its text on one row, the branches side
by side
* overview: each step a cell in the colour of its EIP, to see the shape of a
large route
* fit: the most detailed level in which the whole route fits
Add the same levels to the image, for example camel cmd route-diagram
--zoom=detailed|compact|bare|overview|fit: detailed is the card of today,
compact a card of one line (the kind and its detail on one line, a smaller
icon), bare a mark and its text, overview cells. Fit picks the most detailed
level whose image is not taller than a given height (or the size limit). The
same option for the MCP tool, and a zoom query parameter for the route-diagram
developer console.
What each level keeps of the body types on the arrows (CAMEL-26351) and the
problems of the steps (CAMEL-26352): at compact the labels and callouts as they
are; at bare and overview the warning marks, with the problems in the numbered
list below the route.
The ASCII and Unicode diagrams could take the same levels later.
