Inkscape is similarly scriptable using Python.Ĭorel's CorelDRAW (and Technical Designer) provide for application scripting via VBA and VSTA, with editing support within the standard interface. So you (or your students) can build quite elaborate math-driven graphics "features" for use in the program. However, Illustrator provides its own API and scripting model for Javascript, AppleScript, and Visual Basic for Applications, with complete documentation. For example, its value fields will accept basic math operators (+, -, *, /), but only of one kind (addition and subtraction or multiplication and division) in a keyed-in expression. If so:Īdobe Illustrator provides very little in that regard in its standard interface. It sounds like you are asking if and how it is possible for a user of mainstream graphics programs to use math (especially trig) expressions as input for creating or manipulating graphics. is there a way to use this equation within a graphical program? In other words to use them efficiently you have to be a rather pragmatic mathematician :) On the other hand there are seemingly simple problems that cannot be solved analytically such as computing the length of a curve, finding the intersection of two curves, or defining a curve which is at a constant distance of another (but there are algorithms to compute usable approximations). This is especially useful because you can scale them at will. The curve you obtain by rendering the curve again after applying the transform to just the anchors is the same that you would obtain by applying the transform to an infinity of points of the initial curve. Their most interesting property is that they are "compatible" with affine transforms. These curves can be defined by 4 points and the relationship between these points and the curve is rather intuitive, which is why they are used in drawing programs. That said it does have those features that Affinity Designer lacks, so it will be worth the money for some users.Illustrator (or InkScape) use 3rd-degree Bézier curves (3rd-degree parametric polynomials)(and strangely you cannot use them to make a perfect circle, even if you can approximate one rather easily). The downside is that at $95, VectorStyler is twice as expensive as Affinity Designer, which tops our list of the best Illustrator alternatives, and there's no iPad app or wider ecosystem of other software. We've found the interface to be easy and intuitive, and there are plenty of interesting filters and tools. This Illustrator alternative can handle Illustrator files, and you can also import AI brush collections. Its big sell is its wide range of scalable vector brushes and the inclusion of tools that some users might miss in other alternatives to Illustrator, such as a shape builder, a blend tool and a pattern tool. It used to be available for Mac only but there's now a Windows version too. VectorStyler is a relatively new Illustrator alternative that seems to be expanding its offering. More expensive than competing options with a one-off payment If you’ve never used it, you might want to take advantage of the free trial to see how it feels in practice. It does work out a little cheaper than Illustrator but really the main reason to choose CorelDRAW over Illustrator would be if you prefer the interface and workflow. It can easily import Adobe AI and PSD files, so there are no problems with compatibility, and CorelDRAW now has a browser-based app and iPad app too, making it easier to use the program on the go. It adds in new features including dynamic asset management and a faster adjustments docker for photo editing. There's also CorelDRAW standard, which is aimed at enthusiasts rather than professionals. CorelDRAW Graphics Suite 2021 is available for a one-off payment while the new 2022 version requires a subscription. Because the interfaces and approaches are quite different, fans of each tool will argue, with equal vehemence, that theirs is the easiest to use, but there’s no real objective way of settling this.ĬorelDRAW isn't exactly a cheap Illustrator alternative, but it is more flexible in terms of how you can pay because you can get the software in several ways. Both are packed with features and both have their passionate advocates. In fact, it's hard to say whether CorelDRAW or Illustrator is the 'better' tool. First launched in 1989, CorelDRAW is an Illustrator alternative that has a big following among artists and illustrators.
