+
+# How to create a new pen template
+It takes a bit of experimentation and skill to create a new pen, so be patient.
+
+1. Create a folder in your Vault for your pen options. The default is `Excalidraw/Pens`.
+2. Create a new markdown file in your in the `pen folder` (e.g. `My pen`).
+3. Copy the following template to the markdown file.
+```json
+{
+  "highlighter": true,
+  "constantPressure": false,
+  "hasOutline": true,
+  "outlineWidth": 4,
+  "options": PASTE_PREFECT_FREEHAND_OPTIONS_HERE 
+}
+```
+4. If you don't want your pen to have an outline around your line, change `hasOutline` to `false`. You can also modify `outlineWidth` if you want a thinner or thicker outline around your line.
+5. If you want your pen to be pressure sensitive (when drawing with a mouse the pressure is simulated based on the speed of your hand) leave `constantPressure` as `false`. If you want a constant line width regardless of speed and pen pressure, change it to `true`.
+6. `highlighter` true will place the new line behind the existing strokes (i.e. like a highlighter pen). If `highlighter` is missing or it is set to `false` the new line will appear at the top of the existing strokes (the default behavior of Excalidraw pens).
+7. Go to https://perfect-freehand-example.vercel.app/ and configure your pen. 
+8. Click `Copy Options`.
+9. Go back to the pen file you created in step No.2 and replace the placeholder text with the options you just copied from perfect-freehand.
+10. Look for `easing` in the file and replace the function e.g. `(t) => t*t,` with the name of the function in brackets (in this example it would be `easeInQuad`). You will find the function name on the perfect-freehand website, only change the first letter to be lower case. 
+11. Test your pen in Excalidraw by clicking the `Alternative Pens` script and selecting your new pen.
+
+# Example pens
+My pens: https://github.com/zsviczian/obsidian-excalidraw-plugin/tree/master/ea-scripts/pens
+
+**Fine tipped pen:**
+```json
+{
+  constantPressure: true,
+  options: {
+    smoothing: 0.4,
+    thinning: -0.5,
+    streamline: 0.4,
+    easing: "linear",
+    start: {
+      taper: 5,
+      cap: false,
+    },
+    end: {
+      taper: 5,
+      cap: false,
+    },
+  }
+}
+```
+
+**Thick marker:**
+```json
+{
+  constantPressure: true,
+  hasOutline: true,
+  outlineWidth: 4,
+  options: {
+    thinning: 1,
+    smoothing: 0.5,
+    streamline: 0.5,
+    easing: "linear",
+    start: {
+      taper: 0,
+      cap: true
+    },
+    end: {
+      taper: 0,
+      cap: true
+    }
+  }
+}
+```
+
+**Fountain pen:**
+```json
+{
+  options: {
+    smoothing: 0.22,
+    thinning: 0.8,
+    streamline: 0.22,
+    easing: "easeInQuad",
+    start: {
+      taper: true,
+      cap: true,
+    },
+    end: {
+      taper: 1,
+      cap: true,
+    },
+  }
+}
+```
+# Notes about the pen options
+
+Note, that custom pens are currently not supported by Excalidraw.com. I've submitted a [PR](https://github.com/excalidraw/excalidraw/pull/6069) but there is no guarantee that it will get pushed to production. Your Excalidraw drawing can still be loaded to Excalidraw, but the special pen effects will not be visible there.
+
+If you set a pen in your Excalidraw template file, that pen will be loaded automatically when you create a file using that template. Similarly, when you save a document, it will save your current pen settings as well. The next time you open the document, you can continue to use the same pen.
+
+Pen options are saved with the stroke. This means, that even if you change the ped definition later on, your existing drawings will not be effected.
+
+`outlineWidth` is relative to `strokeWidth`. i.e. if you make the stroke thinner in Excalidraw, the outline will become proportionally thinner as well. `outlineWidth` is only used if `hasOutline` is set to true.
+
+If you don't want your pen to be pressure/speed sensitive, set `constantPressure` to `true`. Setting `constantPressure` to `true` automatically sets `simulatePressure` to `false`.
+
+If you want your pen to be speed sensitive (i.e. the faster you draw the line the thinner it gets), set `options.simulatePressure` to `true`.  If you omit `simulatePressure` from `options` then excalidraw will detect if you are drawing with a mouse or a pen and use pen pressures if available.
+
+You can read more about configuring perfect freehand here: https://github.com/steveruizok/perfect-freehand#documentation
+
+Excalidraw supports all of the easing functions listed here: https://easings.net/#, plus "linear". You can also find details about these easing functions here:
+https://github.com/ai/easings.net/blob/master/src/easings/easingsFunctions.ts
+
+From a performance perspective I recommend linear easing.

+This script arranges selected elements and groups with a fixed inner distance.
+
+Tips: You can use the `Box Selected Elements` and `Dimensions` scripts to create rectangles of the desired size, then use the `Change shape of selected elements` script to convert the rectangles to ellipses, and then use the `Fixed inner distance` script regains a desired inner distance.

+
+This script will reset the start and end positions of the selected arrows. The arrow will point to the center of the connected box and will have a gap of 8px from the box.
+
+Tips: If you are drawing a flowchart, you can use `Normalize Selected Arrows` script to correct the position of the start and end points of the arrows, then use `Elbow connectors` script, and you will get the perfect connecting line!
