Tell us what you were expecting. --\u003e\r\n\u003c!--- Improvement? Tell us how you’d like it to work. --\u003e\r\nthe document should stay in the  viewbox\r\n\r\n## Current Behavior\r\n\u003c!--- Explain the difference from current behavior. --\u003e\r\nWhen we export to svg, there is a glitch on the output file.\r\nthere is a `transform=\"scale(2,2)\"` on the exported shape.\r\nI understand why, but in fact it's useless, because it's vector shape exported.\r\nthe document is defined with the right definition (created with `size(width, height)` in the script)\r\nby adding a `transform`, it modify the preview and the size of the shape in the viewbox.\r\n\r\n## Steps to Reproduce\r\n\u003c!--- Provide an unambiguous set of steps to reproduce. --\u003e\r\n\u003c!--- Including code will make it more likely to be fixed. --\u003e\r\n```\r\nimport processing.svg.*;\r\n\r\nvoid setup() {\r\n  size(400,400, SVG, \"filename_without_pixeldensity.svg\");\r\n  //pixelDensity(2);\r\n}\r\n\r\nvoid draw() {\r\n  circle(width/2,height/2, width/2);\r\n  exit();\r\n}\r\n```\r\n\r\n## Your Environment\r\n\u003c!--- Include details about your environment. --\u003e\r\n\u003c!--- Thousands of people use Processing every day and may not have this issue, --\u003e \r\n\u003c!--- so this gives us clues about why you’re running into a problem. --\u003e\r\n* Processing version: 4.2\r\n* Operating System and OS version: MacOS Ventura 13.2.1\r\n* Other information: Intel 2018 MBP 13\"\r\n\r\n## Possible Causes / Solutions\r\n\u003c!--- Optionally, if you have a diagnosis or fix in mind, please share. --\u003e\r\nRemove the `transform=\"scale(2,2)\"` on each group of shape\r\nor\r\nadjust the document size (`with`and `height`) according to the `pixelDensity` instruction in the `\u003csvg\u003e` tag to have a correct preview and document viewbox.\r\n\r\n","author":{"url":"https://github.com/processing-bot","@type":"Person","name":"processing-bot"},"datePublished":"2023-03-24T08:36:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/693/processing4/issues/693"}
