Automatically calculate metrics and kerning, or use autokerning suggestions as you kern manually. Apply tracking, modify widths, sidebearings and kerning globally or for selected glyphs.Īutomatically or manually build kerning classes and link metrics between glyphs using complex expressions. Space entire phrases and kern according to planned pair lists. Use Auto layers to build predefined glyphs and keep them automatically updated. Build & Assembleīuild glyphs from Components that point to other glyphs, or from Element References that cross-reference each other and can be edited anywhere they appear.ĭecompose a component and unlink a reference to make local changes only. Work on a purely integer grid, or scale, rotate and slant losslessly thanks to FontLab’s fractional drawing precision and live integer rounding, apply the rounding to bake in the integers. ![]() See lengths, angles, curve tension, stem thickness, whitespace distance - measured numerically and visually as you draw. Use upright and slanted grids, flexible guidelines, snapping suggestions and live measurement tools for consistent and precise vector drawing.ĭynamically snap to nodes, angles, stem distances, continuation lines, perpendicular lines and centerlines as you draw. Drag without zooming in for small adjustments with Lever precision dragging.Ĭonvert between the curve types with adjustable precision. Natively edit cubic PostScript Bézier curves and quadratic TrueType curves, including overlapping open paths, using the Contour, Knife, Scissors and Fill tools.ĭrag some nodes and have other nodes or handles follow intelligently with Power Nudge and handle Nudge. Turn them into monochrome fonts via customizable autotracing, or into color OpenType fonts. Paste and import PDF, EPS & SVG vector artwork with monochrome, color or gradient fills and strokes, as well as scanned character sets or color bitmap glyphs. Modulate thickness visually with new Thickness tool. Draft & Drawĭraw outline-based glyphs using the Brush, Pencil, Rapid, Pen, Ellipse / Oval, Rectangle / Polygon / Star tools, in a purely- integer or fractional coordinate space.ĭraw calligraphic letterforms with live, adjustable Power Stroke and Power Brush tools. H, 0.0000000000, 1.4320403835, -0.Work with blazing speed with even most complex contours thanks to FontLab’s optimized architecture.Ĭustomize FontLab’s interface to your needs, and easily navigate it with the intuitive Quick Help system: hover and hold F1. The following example shows a calculation for water including vibrational-rotational coupling surfaces, the corresponding VSCF and VCI calculations a subsequent transformation of the potential to doubly deuterated water. As the external files can be huge for XSURF calculations, they will be stored on the scratch disk given by the Molpro variable $TMPDIR by default. Two options are available, WHERE=home and WHERE=scr. WHERE= variable In combination with the keywords DUMP and EXTERN for an external restart file, the keyword WHERE specifies the path for the external ASCII file. Rauhut, Transformation of potential energy surfaces for estimating isotopic shifts in anharmonic vibrational frequency calculations, J. Due to that a completely different PESTRANS program will be used once XSURF has been called before. While for the old SURF program a fine grid in the new coordinate system will be generated from fits of the fine grid using the old coordinate system, the XSURF program itself will be used to generate a fine grid in the new coordinates, which usually is much faster. Different versions of the PESTRANS program will be used in combination with the SURF and the XSURF programs. This requires a representation of the potential energy surface by polynomials. This allows for the transformation of PESs as needed for the calculation of the vibrational spectra of isotopologues or Franck-Condon factors including Duschinsky rotations. ![]() The PESTRANS program allows to change the coordinate system being used within the representation of the potential by a Duschinsky-like transformation.
