DIS(P) - Display an image

Displays an image on the Lexidata. This will not often be necessary when using the high-level commands, since both GLANCE and RUN do an automatic display.

Parameters

There are some, but default values will normally be acceptable. By default, the current image is displayed unscaled and centred in the center of the Lexidata screen.

Examples

Adam:> DISP

Notes

When displaying an image that has a dimension larger than 640 rows x 512 columns, the parts that lie outside the Lexidata are not displayed. These can be seen by altering the position of the centre of the image. The ACL variables LXXC and LXYC control the position of the centre. For example, to move it up by 100 pixels, set LXYC=LXYC+100.

Use DIPARM to alter the scaling option (note that it is faster NOT to scale the data and MUCH faster, when scaling, to leave LOW = 0, since, where possible, scaling is done by shift operations).
