takepic

#takepic

##Syntax takepic (x1, y1, x2, y2 : int, var buffer : array 1 .. * of int)

##Description The takepic procedure is used to record the pixel values in a rectangle, with left bottom and right corners of (x1, y1) and (x2, y2), in the buffer array. This requires a sufficiently-large buffer (see sizepic ). The drawpic procedure is used to make copies of the recorded rectangle on the screen.

##Example After drawing a happy face, this program copies the face to a new location.

##Details The integer values that takepic places in the buffer can be read or written (using the read and write statements). Unfortunately, if a value happens to be the pattern used to represent the uninitialized value (the largest negative number the hardware can represent) assignment (by:=) and put of the individual integer values in the buffer will fail.

The screen should be in a "graphics" mode. See the setscreen procedure for details. If the screen is not in a "graphics" mode, it will automatically be set to "graphics" mode.

##Details The drawpic, takepic, and sizepic subprogramshave been made obsolete by the subprograms pic_draw.html and**pic_new.html** of the picmodule.html module. Users are strongly suggested to use those routines instead. The picmodule.html module also contains subprograms to load images from files.
