INCLAN: x0, y0, x1, y1

Synopsis

x0, y0, x1, y1

Description

Define the positions of the two reference points (x₀,y₀) and (x₁,y₁) in the standard coordinate system. The standard coordinate system has its origin in the center of an A4 sheet and uses points (1 pt = 0.353 mm) to measure distances in both dimensions. The x-axis points to the right, and the y-axis points up. The values of these plot parameters are available in INCLAN as intrinsic functions: viewx0, viewy0, viewx1 and viewy1. Initial values: x₀ = -250, y₀ = -375, x₁ = 250, y₁ = 375
