Common usage#
The canvas and layout use physical dimensions: mm, cm, in, pt, or px. Layout px is converted using canvas(layout_dpi=96) by default. Export --dpi changes raster pixel dimensions. For example, 160 × 100 mm at 300 DPI gives about 1890 × 1181 px, with the same SVG/PDF page geometry.
On placement, anchor belongs to the new instance, target belongs to the canvas, current group, or an earlier instance, and offset shifts the alignment point:
The nine anchors are top_left, top_center, top_right, middle_left, center, middle_right, bottom_left, bottom_center, and bottom_right. Relative targets must already exist in the same coordinate space. Later add calls paint over earlier ones. Each placement may set rotation and opacity; image placements can also override width, height, fit, and crop independently.
