SHIFT+CLICK applies it as the stroke color. For instance:ĬLICK /SHIFT+CLICK - when you click on a color from the color palette on the bottom of the screen, it applies that as a fill color to the selected object. Lots of work is also done with the mouse, of course. 1 is 'actual size', 3 is 'zoom to selection', 4 is 'zoom to drawing' (all your graphics objects), 5 is 'zoom to page'. The arrow keys by themselves nudge objects around slowly.ġ,3,4,5 - Zoom levels. SHIFT+ARROWKEYS - Move object quickly (20 pixels at a time). The 'resize page to drawing' button is always the last thing I do before exporting, often with 1mm margins. SHIFT+CTRL+D - AKA File > Document Properties. This is where selecting fill colors, line widths, and line styles happens. SHIFT+CTRL+F - pull up the fill and stroke window.

Super useful for laying out multiple panels in a figure, aligning text to an object, creating equal-spaced grids, etc.

SHIFT+CTRL+A - pull up the alignment window. Going into F2 mode lets you select and modify individual nodes on a curve.

Most lines in Inkscape are Bezier curves, meaning they have a series of 'control' points and tangent vectors. This is nothing fancy, it just sets your cursor up to point-and-click objectsį2 - node selection mode. Here are some very useful commands and their keyboard shortcuts:į1 - object selection mode. There's probably a better workaround, but currently, I always export figures that have transparencies as PNGs (SHIFT+CTRL+E to bring up the PNG exporter window) 300dpi is generally plenty of resolution. Warning: transparencies in PDFs will not print well, even if they look fine on a screen.

Get in the habit of closing the window so you don't accidentally edit the PDF after exporting. I strongly recommend using the 'Poppler' importer for PDFs.Įxporting from Inkscape to PDF is as simple as 'save as' (SHIFT+CTRL+S). Likewise, PDF and SVG files can be imported into Inkscape using CTRL+I. Alternatively, double-clicking into an object will move your scope down into the group. When a figure is opened in Inkscape, its components are grouped, often two levels deep for whatever reason. 99% of the time I can get away with setting only the dimensions and font size before exporting, then doing the rest in Inkscape. With a Matlab figure go to File > Export Setup. Resizing things can be tedious sometimes, so it's good practice to programmatically export figures already sized at least close to your desired final dimensions. That said, sometimes Matlab -> PDF -> Inkscape -> SVG just seems to work better, and is something to try if the SVG is misbehaving. points on a scatter plot) are not colored or grouped well in a PDF. Specifically, my experience is that text will not always import nicely as an SVG, but objects (e.g. In theory, exporting figures to SVG should be preferred, but in practice, I find there are sometimes issues. All subsequent advice will assume Matlab since that's what I use. Matlab and Python (specifically matplotlib) can export in PDF or SVG formats. Even on Mac, keyboard shortcuts in X11 use the CONTROL key instead of COMMAND, but should otherwise be familiar – CTRL+C, CTRL+V for copy-paste, CTRL+S for save, etc. Quitting Inkscape will leave X11 on in the background, but quitting X11 will kill Inkscape's host environment and destroy unsaved changes. If on Linux or OSX, launching Inkscape will launch X11 or XQuartz in the background, which is just a non-native 'windowing' application. Photoshop is to Gimp as is Illustrator to Inkscape. Editing raw images like this can be done with Photoshop or Gimp. Image formats like PNG, JPEG, GIF, TIFF, and others are just that – plain old grid-of-pixel images. When importing one of these other file formats, it's good practice to convert to an SVG. Other 'vector graphics' file formats include PDF, EPS, and AI (Adobe Illustrator). Inkscape's native file format is the SVG, which stands for Scalable Vector Graphics. This tutorial is meant to be a 'quick start' guide for using Matlab or Python with Inkscape to make good quality scientific figures. There are good online resources for questions on specific tools and visual effects. In a sentence, this means that at its core, Inkscape is about manipulating objects, vectors, text, and curves, rather than pixels. It is incredibly useful for figure design and layout.
