Inkscape vs Adobe Illustrator for Vector Graphics

I’m about to break 100 figures (that’s photos, diagrams, and combinations thereof) for my book, which in current draft is 150 pages. Whenever possible I create vector images because they scale perfectly. The alternative is a raster (pixel-based) image, which is defined for some number of pixels and becomes pixelated when enlarged. Here’s an extreme example: I drew a simple circle, rasterized a copy of it, and then zoomed in on the top section:

The vectorized version stays smooth at any scale, because the rendering engine is essentially told, “The drawing is a black circle, this size with this line thickness.” (The SVG code is actually <circle cx="50" cy="50" r="40" stroke="black" stroke-width="1" />.) The rasterized version is a fixed rendering of that circle using a specified number of pixels, and that’s as detailed as the image can get.

Raster images are natural for things like photos that begin life as pixel arrays. But computer drawings that are built up using primitive shapes and strokes almost always benefit by preserving that construction. A bonus is that vector files tend to be much smaller than legible raster versions – even in the human-readable Scalable Vector Graphics (SVG) format.

I have created vector images directly in Word (more on this later), Excel, and Python (using matplotlib and seaborn). For just $5 I got a Ukrainian freelancer on Fiverr to vectorize a diagram from an old military publication.

Until recently I used Adobe Illustrator to do more serious vector graphics. But my latest copy of that software is from 2007 and doesn’t always work well in Windows 10. (Yes, I got it back when you could buy and keep using an application instead of having to subscribe.) If I did this stuff all the time I would probably subscribe to Adobe Creative Cloud. But I don’t, so I took a look around and found a popular open-source alternative to Illustrator: Inkscape. It took a day to get comfortable with it, and now it’s great for my purposes. For example, I liked this drawing from a 2004 dissertation by Jorma Jussila, and he was kind enough to send me the vector image, which gave me a tremendous head start creating this diagram:

How Microsoft Let Me Down This Week

In college (1998) I wrote a graphics-heavy term paper in Word. I had invested days of work, saving frequently (as always). At some point Word corrupted the document, but I didn’t realize that because I had kept it open on my computer and the in-process version didn’t give a hint that anything was wrong. Until I tried sending it to a printer, at which point it crashed and I discovered that none of the files contained much that could be salvaged. It took a frantic day to reproduce the paper.

Well, that summer I had a great internship at Microsoft, and – not one to hold a grudge – I have been drafting my current book in Word. (As of today the DOCX is 100MB!) But I have been frequently creating and checking PDFs along the way. In the course of these reviews I discovered that Word is unpredictable in creating and handling vector drawing objects. For example, adding a bevel to a circle causes Word to rasterize it, but you probably won’t notice unless you make a point of inspecting things at high zoom multiples.

Create a circle in Word and it’s a vector drawing (left). Add a bevel and Word silently rasterizes it (right).

I also discovered that Microsoft’s PDF printers and export engines rasterize everything, which is not only a loss of detail, but also a travesty given that vectors are a foundation of the Portable Document Format. Fortunately there are free PDF printers (I verified both doPDF or CutePDF) that preserve vectors.

The Immortality Key

The Immortality Key is an important book. I had only read the Forward and half of the Introduction when I was convinced of the book’s essential thesis:

  • The human psyche has an innate capacity for a common experience of “transcendence,” which in our cultural terms might be called “seeing or knowing God.” Transcendence can be found across cultures and time in religious archetypes and practices. But most humans can only obtain the real transcendental experience with the aid of entheogenic (a.k.a. psychedelic) chemicals.
  • Humans going back to prehistoric times have made ritualistic use of natural entheogens. Many have emphasized that the transcendence found through these chemically-enhanced rituals is critical to the well-being not only of individuals but also of human society.
  • It appears that a single powerful entheogenic experience is sufficient to convert a person for life. (For example, Greeks who underwent the entheogenic ritual at Eleusis were given the title epoptēs, or “witness.” And ongoing research with entheogens has found that a single dose of psilocybin can relieve major depression.)
  • Spiritual use of entheogens has perhaps been stigmatized by abuse in the 1960s and 1970s. The hippie movement profaned the use of entheogens that were, and probably should be, sacred.
  • Modern organized religions and governments have nefariously eliminated access to entheogens. For example, it is astonishing that chemicals like psilocybin and LSD have been banned under DEA Schedule 1, which is reserved for substances “that have a high chance of being abused or causing addiction, and no FDA-approved medical use,” whereas scientific research has always found them to be non-addictive, with low potential for abuse.

How do you “see God?” As with all human traits, there is a spectrum of capacity. Some people are gifted (or afflicted) with transcendental vision – most likely many of those called prophets. For many more people, transcendent vision can be obtained through devoted fasting, prayer, scourging, or meditation. But it appears that anyone can transcend with the use of entheogenic chemicals. The Immortality Key impresses the notion that Christianity is (in my words) a relatively dead religion: Christian doctrine correctly describes transcendence, but Christian rituals are hollow versions of those that humans have relied on for tens of thousands of years to actually experience transcendence. Yes, these hollow rituals are sufficient for some. For others, like me, they at best offer one fleeting glimpses of transcendence.

The Immortality Key has its shortcomings. After the first few chapters the author bogs down flogging the Pagan Continuity Hypothesis and exulting over his discovery of small scraps of evidence he found in a decade of research. Jerry Brown wrote a good review that should be read to put the book in its proper place.

The book does expound upon a few other worthwhile points. The author is an academic classicist, and along the way he (like all classicists) impresses on the reader how little our culture has evolved from that developed by the Greeks in the first millennium BC. Then he details the shocking efforts by early Christians to try to erase that culture. They nearly did, most unconscionably by burning the library at Alexandria. Today we have only 1% of classical texts known to have existed.

The last chapter is an interesting read: It shows how the concept of “witches” was developed by the middle Catholic Church and used to destroy whatever western folk knowledge of entheogens may have otherwise survived. Then, Christian missionaries in the Americas largely succeeded (often through the force of government) to suppress entheogenic use among indigenous Americans. Hopefully we are now at the end of the war on entheogens and the revival of mainstream acceptance of and access to transcendental experience.

Why We Make Things

I recently listened to Peter Korn’s book Why We Make Things and Why It Matters: The Education of a Craftsman. (Like most books, the substance is concentrated in the beginning; and roughly a third of the way in the book becomes relatively unimportant; and the last third often seems like filler to make it long enough to bind and sell as a traditional book.) It is a good exploration of man’s search for meaning, and how man finds meaning in craftsmanship. And I think this is a particularly male struggle: The female psyche finds meaning in the people around her, and particularly in that most powerful and consummate of bonds: between a mother and her children. But the maturing male psyche detaches, leaving him adrift in abject existential loneliness. To become a man he has to discover or build his purpose. He may find meaning in social spheres, but he can also find meaning in the creation or nurturing of things – i.e., he can find meaning as a craftsman.

Korn beautifully describes the nature of craftsmanship – how an artisan develops intuition and connection with materials and processes; the state of “flow” a master can attain practicing his art. And Korn repeats lamentations about how the industrial revolution turned craftsmen into automata, destroying the opportunity for so many working men to find essential meaning in their labor.

Book Review: Life at the Bottom, by Theodore Dalrymple

In April, National Review published an entire issue of essays on California exploring the dismal results of the state’s increasingly progressive political experiments. The punchline is that dysfunctional government has managed to make that otherwise attractive geographic region so unlivable that people with the means to leave for other states are doing so in droves.

Among wealthy democratic nations, Great Britain has taken the lead in boldly implementing progressive ideology in both government and culture. Theodore Dalrymple has been documenting the dismal results for years. His cautionary essays are essential reading for anyone who traffics in political ideas. Life at the Bottom is a collection of those essays.
