Tse YM's Flexi Plasmid Draw Basic
Copyright reserved by Maverick Tse Yuk Man, 2008
version 1.8 release
- Enter the name(optional) and size of a plasmid (any positive integer, required field) in the first two fields
- Enter the starting co-ordinate of your plasmid feature (in bp)
- Enter the ending co-ordinate of the feature. If this value is less than the starting co-ordinate, the arrow will be drawn anti-clockwise.Note that feature cannot span across the top most point of the circle. The illusion of a feature spanning across the top of circle can be done by creating 2 features (Feature 1: x-->plasmid size; Feature 2: 0 -->y)
- Add all the features required (up to 15). The the features can overlap each other without problem.
- Tick the 'visibility' checkboxes on the left to show only the features that you want.
- Click "Generate SVG Code" button to get your plasmid map as SVG code in the text box at the bottom.
- Copy and save the SVG code in a text file with the extension .svg
- View the plasmid by opening the svg file with Firefox or Opera browser. The image can be edited visually with Inkscape and save as PNG or WMF files for use with other software. If you are REALLY lazy or you cannot run Inkscape, you can view the image in Firefox and hit PrintScreen and edit the captured bitmap.
- Canvas Size: determines the maximum size of the image. Default is 800x600 pixels.
- Radius: determines the radius of the circular plasmid to be drawn. Default is 200px.
- Feature Width: set the "thickness" of the arrow or box for your plasmid features. Default is 15px.
- Arrow(checkbox): tick the box to give a feature an arrow head. Untick it to draw a box.
- Arrow angle: set the length of the arrow head if arrow is to be drawn. Default is 5 degree.
- Wing size: determines how wide the arrow heads are. Default is 5px.
- Text size: set the text sizes in pixel. Plasmid name and size are 2px larger than the feature labels.
- Show text(checkbox): If ticked, plasmid name, size and feature labels will be displayed. Untick to remove all labels.
- Name:(textbox) and Italic(checkbox): type the feature name in the textbox. If the label needs to be italic, tick the italic checkbox.
- Color: Three fields for entering the percentage of Red, Green and Blue. The colors are mixed to give a feature's fill color. They are percentage and accept values of 0-100 only. Default color is black (Red=0, Green=0, Blue=0). White is R=100,G=100,B=100.
Rainbow Color Wheel and RGB percentage values
Hint: You can draw a truncated circle or arrow by making a box-shaped feature white, and cover the feature/backbone at the bottom. Note that features that are drawn later can cover the features drawn earlier. e.g. Feature 5 can cover Feature 3 but not the reverse.
