§ 12.11.27 - DPI

Scripting command: dpi [xDPI=1-3200] [yDPI=1-3200]

Note: All available scripting operations are listed on the Script operator page.

Note: The script command sets the image's DPI. The image's DPI may be obtained from the preset variables m_xdpi and m_ydpi.

Here's how to change only one of the two values:
dpi 72 m_ydpi:# Only change xdpi dpi m_xdpi 300:# Only change ydpi

Applies and reads DPI from the active image.

DPI means "Dots Per Inch." DPI sets the relationship between image pixels and real-world space. For instance, when you print an image, if it is 300 DPI, and the image resolution is 900 wide by 1200 high, it (should) print out as a 3 inch by 4 inch picture on the page.

The DPI operator lets you set the horizontal (x) DPI and the vertical (y) DPI individually; but in typical circumstances, they should be the same. The operator tries to help you with this by setting the Y DPI whenever you set the X DPI.

If you need to set different values for X DPI and Y DPI, just set X first and then Y.

A new DPI setting is applied when you press Apply, or when you make any area selection on an image in ✓ Modal area selection operation, or when you press Apply in ✓ Modal area selection operation.
