One needs to know the `kind` to know what the float values mean. But it's not sufficient, because if one called `ellipseMode` before, the values may mean center x and y, or corner x and y, either width or radius.\n\nI didn't find a way to query `ellipseMode` or `rectMode`.\n\n#### Benefits\nAdding a way to query this information would help cross framework use of the `PShape` data structures.\n\n#### Challenges\nI think adding two getters to `PShape` shouldn't have any negative impact, but I'm not very familiar with the code base to be sure.\n\n#### Additional context\nHere a wip function where I try to convert an ELLIPSE `PShape` to an OPENRNDR `Shape`. This is incomplete, because the meaning of params 0, 1, 2 and 3 depend on the `ellipseMode` used, and there's no way to figure this out (I think).\n\n```kotlin\n        PShape.PRIMITIVE -\u003e {\n            listOf( // 101\n                when (kind) {\n                    PShape.RECT -\u003e Rectangle( // 30\n                        params[0] * 1.0, params[1] * 1.0,\n                        params[2] * 1.0, params[3] * 1.0\n                    ).contour\n\n                    PShape.ELLIPSE -\u003e Ellipse( // 31\n                        params[0] * 1.0, params[1] * 1.0,\n                        params[2] * 0.5, params[3] * 0.5\n                    ).contour\n\n                    PShape.LINE -\u003e LineSegment(\n                        params[0] * 1.0, params[1] * 1.0,\n                        params[2] * 1.0, params[3] * 1.0\n                    ).contour\n\n                    // ARC, TRIANGLE, QUAD, SPHERE, BOX\n                    else -\u003e error(\"unsupported primitive kind: $kind\")\n                }\n            )\n\n```\n\n`PShape` holds `ellipseMode` and `rectMode` variables, but they are `protected` and without getters.\n\n### Would you like to help implement this enhancement?\n\nI’m not sure yet","author":{"url":"https://github.com/hamoid","@type":"Person","name":"hamoid"},"datePublished":"2025-12-12T12:25:43.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/1359/processing4/issues/1359"}
