The horizontal position of the graphics cursor gety Retrieves the current horizontal graphics cursor position Return Value The color of the pixel as an RGB triplet getx Vertical point at which to query the pixel color Horizontal point at which to query the pixel color Retrieves the color as an RGB triplet at the pixel at the specified coordinates Parameters Parameter getpixelįortran function getpixel ( x, y ) Description This measurement should be identical to the horizontal direction in most cases. The logical pixels per inch in the vertical direction. Otherwise, the operating system will shield the application from retrieving the true dots-per-inch. Note that the application should call setapplicationdpiaware() if the application wishes to perform true dots-per-inch calculations. Retrieves the current system logical pixels per inch (measured in the vertical axis). Pointer to the structure to fill with the arc details Retrieves the arc coordinates used for the latest arc drawing request. Vertical point at which to start flood fill operationįortran subroutine getarccoords ( arccoords ) Description Horizontal point at which to start flood fill operation Parameters Parameterįortran subroutine floodfill (x, y, border) Descriptionįills in the screen starting at point ( x, y) until the color border is encountered. In C, the array is one-dimensional with the first horizontal position followed by the first vertical position followed by the second horizontal position, etc. In Fortran, the horizontal positions in the first column, and the vertical position in the second column. Parameters Parameterįortran subroutine fillpoly (numpoints, points) Descriptionĭraws a filled polygon of numpoints points using the locations in points. Parameters ParameterĬ void fillellipse (x, y, xradius, yradius)įortran subroutine fillellipse (x, y, xradius, yradius) Descriptionĭraws a filled ellipse centered at ( x, y) with the given radius using the current color. The start angle, stangle, and end angle, endangle, are measured in degrees counterclockwise with 0 degrees at 3 o’clock. Parameters ParameterĬ void ellipse (x, y, stangle, endangle, xradius, yradius)įortran subroutine ellipse (x, y, stangle, endangle, xradius, yradius) Descriptionĭraws an ellipse centered at ( x, y) with the given radius using the current color. One to draw a top on the bar, zero to leave emptyįortran subroutine circle (x, y, radius) Descriptionĭraws a circle centered at ( x, y) with the given radius using the current color Parameters Parameterįortran subroutine drawpoly (numpoints, points) Descriptionĭraws a polygon of numpoints points using the locations in points. The bar is outlined using the current line color and style. Parameters ParameterĬ void bar3d (left, top, right, bottom, depth, topflag)įortran subroutine bar3d (left, top, right, bottom, depth, topflag) Descriptionĭraws a three-dimensional rectangular, filled bar using the currently selected color and fill pattern. Parameters Parameterįortran subroutine bar (left, top, right, bottom) Descriptionĭraws a rectangular, filled bar using the currently selected color and fill pattern. arcĬ void arc (x, y, stangle, endangle, radius)įortran subroutine arc (x, y, stangle, endangle, radius) Descriptionĭraws a circular arc centered at ( x, y) in the current color. The graphics cursor, however, is never visible on the screen. The moveto subroutine can be used to set the position directly. A handful of routines will use this in-memory screen coordinate for drawing. One concept to understand in this section is the existence of a “current position” of the graphics cursor on the screen. The following subprograms provide the ability to draw shapes, lines, and other graphics primitives.
