and ellipses. The equivalent rendering is a set of simple graphic objects to support an SCP that only understands the simple​ graphical objects.​

C.10.5.1.3.2 Rotation​

All Compound Graphics can be rotated by specifying a Rotation Angle (0070,0230) value and a Rotation Point (0070,0273). The​ convention for rotation is that positive angle values are defined as counterclockwise around Rotation Point (0070,0273).​

C.10.5.1.3.3 Ellipses​

For the Compound Graphic Type (0070,0294) ELLIPSE, exactly 2 points shall be present inside Graphic Data (0070,0022). The first​ point is the top/left hand corner (TLHC) and the second point is the bottom/right hand corner (BRHC) of the bounding rectangle (see​ Figure C.10.5-2).​

C.10.5.1.3.4 Rectangles​

For the Compound Graphic Type (0070,0294) RECTANGLE, exactly 2 points shall be present inside Graphic Data (0070,0022). The​ first point is the top/left hand corner of the rectangle (TLHC) and the second point is the bottom/right hand corner (BRHC) of the​ rectangle (see Figure C.10.5-2).​

C.10.5.1.3.5 Multi-lines​

For the Compound Graphic Type (0070,0294) MULTILINE, the list of points inside Graphic Data (0070,0022) is an n-tuple list of start​ and end points of straight lines to be drawn (see Figure C.10.5-3).​

If Rotation Angle (0070,0230) is present, all points in the MULTILINE are rotated around the same Rotation Point (0070,0273).​

C.10.5.1.3.6 Cut and Infinite-lines​

For the Compound Graphic Type (0070,0294) CUTLINE or INFINITELINE, exactly two points shall be present inside Graphic Data​ (0070,0022). The rendering of these lines always extends to the borders of the render area of a view(see Figure C.10.5-4).​

Figure C.10.5-5. CUTLINE on the Left and CUTLINE with gap on the Right​

In case of a CUTLINE, two arrows shall be drawn perpendicular to the cutline. The arrows ends shall be positioned at the midpoints​ of each half of the cutline. The arrow heads shall point toward the cutline and shall be drawn in the positive right half-plane of the​ cutline before rotation. Typically, the arrows indicate the viewing direction for MPR renderings that are referenced by these lines.​

Gap Length (0070,0261) defines the diameter of the circular area where the CUTLINE or INFINITELINE is not rendered. Center of​ the circular area is Rotation Point (0070,0273). Since the dimension units of the Gap Length is DISPLAY, independent of the value​ of Compound Graphic Units (0070,0282), the length of the gap is not changed by zoom operations on the image performed by the​ application.​

For the Compound Graphic Type (0070,0294) RANGELINE exactly two points shall be present inside Graphic Data (0070,0022).​

C.10.5.1.3.8 Ruler​

For the Compound Graphic Type (0070,0294) RULER, exactly two points shall be present inside Graphic Data (0070,0022) defining​ the ruler line.​

Tick Alignment (0070,0274) defines the alignment of the ticks.​

BOTTOM - ticks are aligned to the lower part of the line, where the first point of the line is on the left and the line extends horizontally​ to the right.​

CENTER - ticks are centered on the line.​

- Standard -​

TOP - ticks are aligned to the upper part of the line, where the first point of the line is on the left and the line extends horizontally to​ the right.​

Tick Label Alignment (0070,0279) defines the alignment of the tick labels.​

BOTTOM - labels are aligned to the lower part of the line, where the first point of the line is on the left and the line extends horizontally​ to the right.​

TOP - labels are aligned to the upper part of the line, where the first point of the line is on the left and the line extends horizontally to​ the right.​

The presence, labeling and units of the ticks on the line is application dependent(see Figure C.10.5-7). If present as numerical values,​ the labels of the ticks shall increase toward the second point.​

C.10.5.1.3.9 Axis​

For the Compound Graphic Type (0070,0294) AXIS, exactly two points shall be present inside Graphic Data (0070,0022) defining​ the axis line.​

The Major Ticks Sequence (0070,0287) specifies the placement and label of the ticks. The rendering of the minor ticks is left to the​ application.​

Tick Alignment (0070,0274) defines the alignment of the ticks.​

BOTTOM - ticks are aligned to the lower part of the line, where the first point of the line is on the left and the line extends horizontally​ to the right.​

CENTER - ticks are centered on the line.​

TOP - ticks are aligned to the upper part of the line, where the first point of the line is on the left and the line extends horizontally to​ the right.​

Tick Label Alignment (0070,0279) defines the alignment of the tick labels.​

BOTTOM - labels are aligned to the lower part of the line, where the first point of the line is on the left and the line extends horizontally​ to the right.​

TOP - labels are aligned to the upper part of the line, where the first point of the line is on the left and the line extends horizontally to​ the right.​

C.10.5.1.3.10 Crosshairs​

For Compound Graphic Type (0070,0294) CROSSHAIR, exactly one point shall be present inside Graphic Data (0070,0022). This​ point is the origin of the CROSSHAIR (see Figure C.10.5-8).​

Tick Alignment (0070,0274) and Tick Label Alignment (0070,0279) are also valid for the CROSSHAIR. Tick rendering is application​ dependent.​

- Standard -​

Figure C.10.5-8. CROSSHAIR Example Showing BOTTOM Tick Labels Alignment​

Gap Length (0070,0261) defines the diameter of the circular area around the origin where the CROSSHAIR is not rendered. Since​ the dimension units of the Gap Length is DISPLAY, independent of the value of Compound Graphics Units (0070,0282), the length​ of the gap is not changed by zoom operations on the image performed by the application.​

Diameter of Visibility (0070,0262) defines the diameter of the circular area around the origin where the CROSSHAIR is rendered.​ Since the dimension units of the Diameter of Visibility is DISPLAY, independent of the value of Compound Graphic Units (0070,0282),​ the size of the crosshair is not changed by zoom operations on the image performed by the application.​

The value of Tick Alignment (0070,0274) shall be CENTER.​

C.10.5.1.3.11 Arrows​

For the Compound Graphic Type (0070,0294) ARROW, two points shall be present inside Graphic Data (0070,0022). The first point​ is the anchor point, the second point is the foot point of the arrow(see Figure C.10.5-9). The arrow head style at the anchor point is​ not specified.​
