ZTERM

This escape returns the X and Y-Axis DPI or Dots Per Inch. This function is useful when displaying bitmaps and you need to use a different bitmap file to keep the real size of the printed bitmap the same, despite differences in printer resolution.

 

Example

This displays one bitmap for 300 DPI and another for 600 DPI:

PRINT CHR$(27);"i";

INPUT "";DPIX,DPIY

FILENAME = ""

IF DPIX = 300 AND DPIY = 300 THEN &

FILENAME = "300DPI.BMP"

IF DPIX = 600 AND DPIY = 600 THEN &

FILENAME = "600DPI.BMP"

IF FILENAME <> "" THEN &

PRINT CHR$(27);"b";FILENAME;CHR$(0);
