Enum UnitMode

Namespace

LMKit.Graphics.Primitives

Assembly

LM-Kit.NET.dll

Selects the measurement unit used by geometry, drawing, layout, and rendering APIs.

public enum UnitMode

Fields

Pixels = 0

Device pixels of the current raster target (image, surface, or display).

One pixel corresponds to one sample in the bitmap. Conversions from absolute units depend on the effective DPI of the raster target. Use this for direct bitmap operations and final render outputs.

DeviceIndependentPixels = 1

Device-independent pixel (DIP), defined as 1/96 of an inch.

In LM-Kit’s normalized view space (96 DPI), 1 DIP == 1 pixel. Prefer this for DPI-stable layout and geometry when you want sizes to be independent of the output device’s resolution.

Points = 2

Typographic point, defined as 1/72 of an inch.

Common in page composition and document formats. Use for PDF/OpenXML page metrics and font-related sizes. At 96 DPI, 1 pt equals 96/72 ≈ 1.3333 pixels.

Inches = 3

Inch (in), absolute physical length.

1 in = 25.4 mm = 2.54 cm = 72 pt = 96 DIP (in LM-Kit’s 96 DPI view space).

Millimeters = 4

Millimeter (mm), absolute physical length.

1 mm = 0.1 cm = 1/25.4 in.

Centimeters = 5

Centimeter (cm), absolute physical length.

1 cm = 10 mm = 0.3937 in.

Remarks

Absolute units (Inches, Millimeters, Centimeters, Points) are DPI-independent. Relative units (Pixels, DeviceIndependentPixels) scale with the target DPI. By convention, LM-Kit uses a normalized 96 DPI “view space”, so 1 DIP equals 1 pixel at 96 DPI.
