BITMAP ENABLE

Enable bitmap graphics on the target machine. Bitmap resolution and colors depends on hardware. Enabling the bitmap also sets the starting address in memory, for those computers that have graphics mapped in memory.

Given the great variety of hardware that ugBASIC supports and the isomorphic approach adopted, this commands can be used to require a specific resolution, color depth and other characteristics in a hardware independent way.

In this regard, the following approach has been adopted. It is possible to ask for specific chacteristics, such as height and width of the screen. However ugBASIC will choose the closest resolution, based on the hardware on which it will runs.

Likewise, if no type of resolution constraint is set, the best is offered.

To change resolution and colors, you can use the ([width],[height],[colors]), ([width],[height]) or the ([colors]) syntax after BITMAP ENABLE command. So, if you omit a parameters, it means that it is not important to set.

Join BASIC 10Liner Contest with ugBASIC!

An interesting competition is held at the beginning of each year: the BASIC 10Liner Contest. It is possible to use ugBASIC to participate in the next "BASIC10Liner" competition, in the following categories:

  • PUR-120 - A game in 10 lines of max 120 characters (w/abbrev.)
  • EXTREME-256 - A game in 10 lines of max 256 characters (w/abbrev.)
  • SCHAU - Any program in 10 lines of max 256 characters (w/abbrev.)
In order to reduce space you can use this abbreviation for this instruction: 

BITMAP ENABLE ↔ Bm En
