how to create rectangle in html

Quadrilaterals

Draw a rectangle that has a lower left corner at (0,0) and an upper right corner at (2,4). Create the rectangle with curved corners by specifying the curvature as the scalar value For data units of equal length along both the x-axis and y-axis, use axis equal. I'm not sure what you mean, HTML and CSS are not programming languages and do not have methods or functions. CSS is just applying a certain style to the element with the id "rectangle". I guess in a way it is "calling" the #rectangle "method" – tjboswell Dec 19 '13 at

A Graphics object encapsulates state information needed for the basic rendering operations that Java ceeate. This state information includes the following properties: The Component object on which to draw.

A translation origin for rendering and clipping coordinates. The current clip. The current color. The current font. The current logical pixel operation function XOR how to decoupage pictures onto wood Paint. Coordinates are infinitely thin and lie between the pixels of the output device. Operations that draw the outline of a figure operate by traversing an infinitely thin path between pixels with a pixel-sized pen that hangs down and to the right of the anchor point on the path.

Operations that fill a figure operate by filling the interior of that infinitely thin path. Operations that render horizontal text render the ascending portion of character glyphs entirely above the baseline coordinate. The graphics pen hangs down and to the right from the path it traverses.

This has the following implications: If you draw a figure that covers a given rectangle, that figure occupies one extra row of pixels on the right and bottom edges as compared to filling a figure that is bounded by that same rectangle. If you draw a horizontal line along the same y coordinate as the baseline of a line of text, that line is drawn entirely below the text, except for any descenders.

All coordinates that appear as arguments to the methods of this Graphics object are considered rectabgle to the translation origin of this Graphics object prior to the invocation of the method. All rendering operations modify only pixels which lie within the area bounded by the current clip, which rectanglee specified by a Shape in user space and is controlled by the program using the Graphics object.

This user clip is transformed into device space and combined with the device htlwhich is defined by the visibility of windows and device extents. The combination of the user clip and device clip defines the composite clipwhich determines the final clipping region. The user clip cannot be modified by the rendering system to reflect the resulting composite clip.

The user clip can only be changed through the setClip or clipRect methods. All drawing or writing is done in the current color, using the current paint mode, and in the current font. Since: JDK1. ColorsetFont java. Graphics create int x, int y, int width, int height Creates a new Graphics object based on this Graphics object, but with a new translation and clip area.

Rectangle getClipBounds Rectangle r Returns the bounding rectangle of the current clipping area. Rectangle getClipRect Deprecated. As of JDK version 1. FontMetrics getFontMetrics Gets the font metrics of the current font. String toString Returns a String object representing this Graphics object's value. Methods inherited from class java. This constructor is the default constructor for a graphics context. Since Graphics is an abstract class, applications cannot call this constructor directly.

Graphics contexts are obtained from other graphics contexts or are created by calling getGraphics on yow component. See Also: createComponent. Returns: a new graphics context that is a copy of this graphics context. The new Graphics object has its origin translated to the specified point xy.

Its clip area is determined by the intersection of the original clip area with the specified rectangle. The arguments are all interpreted in the coordinate system of the original Graphics object. The new graphics context is identical to the original, except in two respects: The new graphics context is translated by xy.

That is to say, the point 0howw in the new graphics context is the same as x ro, y in the original graphics context. The new graphics context has an additional clipping rectangle, in addition to whatever translated clipping rectangle it inherited from the original graphics context.

The origin of the new clipping rectangle is at 00and its size is specified by the width and height arguments. Parameters: x - the x coordinate. Returns: a new graphics context. See Also: translate int, int tto, clipRect int, int, int, int translate public abstract void translate int x, int y Translates the origin of the graphics context to the point xy in the current coordinate system.

Modifies this graphics context so that its new origin corresponds to the point xy in this graphics context's original coordinate system. All coordinates used in subsequent rendering operations on this graphics context will be relative to this new how to create rectangle in html. Returns: rectanvle graphics context's current color.

All subsequent graphics operations using this graphics context use this specified color. Hrml c - the new rendering how to create rectangle in html. See Also: ColorgetColor setPaintMode public abstract void setPaintMode Sets the paint mode of this graphics context to overwrite the destination with this graphics context's current color.

This sets the logical pixel operation function to the paint or overwrite mode. All subsequent rendering operations will overwrite the destination with the current color. This specifies that logical pixel operations are performed in the XOR mode, which alternates pixels between the current color and a specified XOR color.

When drawing operations are performed, pixels which hoq the current color are changed to the specified color, and vice versa. Pixels that are of colors other than those two colors recfangle changed in an unpredictable but reversible manner; if the same figure is drawn twice, then all pixels are restored to their original values.

Returns: this graphics context's current font. All subsequent text operations using how to construct a model pyramid graphics context use this font. A null argument is silently ignored. Parameters: font - the font. See Also: getFontdrawString java. String, int, intdrawBytes byte[], int, int, int, intdrawChars char[], int, int, int, int getFontMetrics public FontMetrics getFontMetrics Gets the font metrics what did dr edward jenner invented the current font.

Returns: the font metrics of this graphics context's current font. Parameters: f - the specified font Returns: the font metrics for the specified font. This method refers to the user clip, which is independent of the clipping associated with device bounds and what is microsoft.

net framework 1. 1 visibility. If no clip has previously been set, or if the clip has been cleared using setClip nullthis method returns null. The coordinates in the rectangle are relative to the coordinate system origin of this graphics context. Returns: the bounding rectangle of the current clipping area, or null if no clip is set. The resulting clipping area is the intersection of the current clipping area and the specified rectangle. If there is no current clipping area, either because the clip has never been set, or the clip has been cleared using setClip nullthe specified rectangle becomes the new clip.

This method sets the user clip, which is independent of the clipping associated with device bounds and window visibility. This method can only be used to make the current clip smaller. To set the current clip larger, use any of the setClip methods. Rendering operations have no effect outside of the clipping area.

Crdate x - the x coordinate of the rectangle to intersect the clip with y - the y coordinate of the rectangle to intersect the clip with width - the width of the rectangle to intersect the clip with height - the height of the rectangle to intersect the clip with See Rectanyle setClip int, int, int, intsetClip Shape setClip public abstract void setClip int x, int y, int width, int height Sets the current clip to the rectangle specified by the given coordinates.

Parameters: rsctangle - the x coordinate of the new clip rectangle. This method returns the user clip, which is independent of the clipping associated with device bounds and window visibility. Returns: a Shape object representing the current clipping area, or null if no clip is set.

Not all objects that implement the Shape interface can be used to set the clip. The only Shape objects that are guaranteed to be supported are Shape objects that are obtained via the getClip method and via Rectangle objects. From the point specified by x and ythis method copies downwards and to the right.

What does the name devina mean copy an area of the component to the left or upwards, specify a negative value for dx or dy. If a portion of the source rectangle lies outside what does inhibit mean sexually bounds of the component, or is obscured by another window or component, copyArea will be unable to copy the associated pixels.

The area that is omitted can be refreshed by calling the component's paint method. Parameters: x - the x coordinate hhml the source rectangle. Parameters: x1 - the first point's x coordinate. The resulting rectangle covers an area width pixels wide by height pixels tall. The rectangle is filled using the graphics context's current color. Parameters: x - the x coordinate of the rectangle to be filled.

Color drawRoundRect public abstract void drawRoundRect int x, int y, int width, int height, int arcWidth, int arcHeight Draws an outlined round-cornered rectangle using this graphics context's current color.

Description

Zig Mandel is correct: it should be filled and then stroked. The reason is that if you stroke and then fill then the line width is halved. Try it with a really thick line width (say, 20) and compare a rounded rectangle which is filled with the background colour to a rounded rectangle which is not filled. The x attribute defines the left position of the rectangle (e.g. x="50" places the rectangle 50 px from the left margin) The y attribute defines the top position of the rectangle (e.g. y="20" places the rectangle 20 px from the top margin) The CSS fill-opacity property defines the opacity of the fill color (legal range: 0 . Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. See below for more details. Let us look at each type in turn: The Rectangle. the little squares in each corner mean "right angle" A rectangle is a four-sided shape where every angle is a right angle (90°).

A Rectangle object's width and height are public fields. The constructors that create a Rectangle , and the methods that can modify one, do not prevent setting a negative value for width or height. A Rectangle whose width or height is exactly zero has location along those axes with zero dimension, but is otherwise considered empty. The isEmpty method will return true for such a Rectangle. Methods which test if an empty Rectangle contains or intersects a point or rectangle will always return false if either dimension is zero.

Methods which combine such a Rectangle with a point or rectangle will include the location of the Rectangle on that axis in the result as if the add Point method were being called. A Rectangle whose width or height is negative has neither location nor dimension along those axes with negative dimensions. Such a Rectangle is treated as non-existant along those axes. Such a Rectangle is also empty with respect to containment calculations and methods which test if it contains or intersects a point or rectangle will always return false.

Methods which combine such a Rectangle with a point or rectangle will ignore the Rectangle entirely in generating the result. If two Rectangle objects are combined and each has a negative dimension, the result will have at least one negative dimension. Methods which affect only the location of a Rectangle will operate on its location regardless of whether or not it has a negative or zero dimension along either axis.

Note that a Rectangle constructed with the default no-argument constructor will have dimensions of 0x0 and therefore be empty. That Rectangle will still have a location of 0,0 and will contribute that location to the union and add operations. Code attempting to accumulate the bounds of a set of points should therefore initially construct the Rectangle with a specifically negative width and height or it should use the first point in the set to construct the Rectangle.

Frequently operations may produce a result that exceeds the range of a bit integer. The methods will calculate their results in a way that avoids any bit overflow for intermediate results and then choose the best representation to store the final results back into the bit fields which hold the location and dimensions. The location of the result will be stored into the x and y fields by clipping the true result to the nearest bit value.

The values stored into the width and height dimension fields will be chosen as the bit values that encompass the largest part of the true result as possible. Generally this means that the dimension will be clipped independently to the range of bit integers except that if the location had to be moved to store it into its pair of bit fields then the dimensions will be adjusted relative to the "best representation" of the location.

If the true result had a negative dimension and was therefore non-existant along one or both axes, the stored dimensions will be negative numbers in those axes. If the true result had a location that could be represented within the range of bit integers, but zero dimension along one or both axes, then the stored dimensions will be zero in those axes.

Parameters: p - a Point that is the upper-left corner of the Rectangle d - a Dimension , representing the width and height of the Rectangle Rectangle public Rectangle Point p Constructs a new Rectangle whose upper-left corner is the specified Point , and whose width and height are both zero.

Parameters: p - a Point that is the top left corner of the Rectangle Rectangle public Rectangle Dimension d Constructs a new Rectangle whose top left corner is 0, 0 and whose width and height are specified by the Dimension argument. Parameters: d - a Dimension , specifying width and height Method Detail getX public double getX Returns the X coordinate of the bounding Rectangle in double precision.

This method is included for completeness, to parallel the getBounds method of Component. Note that there is no guarantee that the returned Rectangle2D is the smallest bounding box that encloses the Shape , only that the Shape lies entirely within the indicated Rectangle2D. The bounding box returned by this method is usually tighter than that returned by the getBounds method and never fails due to overflow problems since the return value can be an instance of the Rectangle2D that uses double precision values to store the dimensions.

Note that the definition of insideness can lead to situations where points on the defining outline of the shape may not be considered contained in the returned bounds object, but only in cases where those points are also not considered contained in the original shape. If a point is inside the shape according to the contains point method, then it must be inside the returned Rectangle2D bounds object according to the contains point method of the bounds.

If a point is not inside the shape , then it might still be contained in the bounds object:. This method is included for completeness, to parallel the setBounds method of Component. Parameters: r - the specified Rectangle Since: 1.
