| PUT (Graphics Statement) Statement Details |
| |
| Syntax |
| PUT [STEP](x, y),arrayname[(indices)][,actionverb] |
| |
| Argument Description |
| STEP Indicates that the given x and y coordinates are |
| relative, not absolute. The coordinates are treated as |
| distances from the most recent cursor location, not |
| distances from the (0,0) screen coordinate. |
| |
| For example, if the most recent point referenced were |
| (10,10) then |
| PUT STEP (10,5),Ball |
| would put the object stored in Ball at (20,15). |
| |
| (x,y) Coordinates specifying the top-left corner of the |
| rectangle enclosing the image to be placed in the |
| current output window. |
| arrayname The name of the array that holds the image. See the |
| entry for GET (Graphics) for the formula that computes |
| the size of this array. The array can be a |
| multidimensional array. |
| indices Specifies that the image is retrieved starting from the |
| designated array element, rather than at the first |
| array element. |
| actionverb The actionverb determines the interaction between the |
| stored image and the one already on the screen. |
| |
| The different values for actionverb are described in the following |
| list. The default actionverb is XOR. |
| |
| Verb Description |
| PSET Transfers the data point-by-point onto the screen. Each |
| point has the exact color attribute it had when it was |
| taken from the screen with GET. |
| PRESET The same as PSET except that a negative image (for |
| example, black on white) is produced. |
| AND Used when the image is to be transferred over an existing |
| image on the screen. The resulting image is the result of |
| a logical AND of the stored image and the screen; points |
| that had the same color in both the existing image and the |
| stored image remain the same color, while those points that |
| do not have the same color in both the existing image and |
| the stored image do not. |
| OR Used to superimpose the image onto an existing image; the |
| stored image does not erase the previous screen contents. |
| The resulting image is the product of a logical OR of the |
| stored image and the screen image. |
| XOR A special mode often used for animation. XOR causes the |
| points on the screen to be inverted where a point exists in |
| the array image. This behavior is exactly like that of the |
| cursor: when an image is placed on the screen against a |
| complex background twice, the background is restored. This |
| allows you to move an object around the screen without |
| erasing the background. |
