* Paint Class Introduction

*

* Paint is a brush, plays a very important role in the drawing process, the brush mainly preserves the color,

* style, such as drawing information, specify how to draw text and graphics, brush objects have many settings methods,

* Can be broadly divided into two categories, one is related to graphic drawing, the other is related to text rendering.

*

* 1. Graphic drawing

* SETARGB (int a,int r,int g,int b);

* Set the color to be drawn, a for transparency, and r,g,b for the color value.

*

* SETALPHA (int a);

* Set the transparency of the drawing drawing.

*

* SetColor (int color);

* Sets the color of the drawing, which is represented by a color value that includes transparency and RGB colors.

*

* Setantialias (Boolean AA);

* Set whether anti-aliasing is used, consumes large resources, and the drawing speed slows down.

*

* Setdither (Boolean dither);

* Set whether to use Image jitter processing, will make the picture color more smooth and full, image clearer

*

* Setfilterbitmap (Boolean filter);

* If the item is set to True, the image will filter out the optimized operation of the bitmap image during animation to speed up the display

* Speed, this setting depends on the settings of dither and Xfermode

*

* Setmaskfilter (Maskfilter maskfilter);

* Set Maskfilter, you can use different maskfilter to achieve the effect of filter, such as filter, stereo, etc. *

* Setcolorfilter (Colorfilter colorfilter);

* Set the color filter to achieve a color-free conversion effect when drawing colors

*

* Setpatheffect (Patheffect effect);

* Set the effect of drawing path, such as point drawing line, etc.

*

* Setshader (Shader Shader);

* Set the image effect, use shader can draw a variety of gradient effect

*

* Setshadowlayer (float radius, float dx,float dy,int color);

* Set the shadow layer below the graph, create a shadow effect, radius is the angle of the shadow, DX and dy are the distance from the shadow on the x-axis and the y-axis, color is the shade of the shadow

*

* SetStyle (Paint.style Style);

* Set the style of the brush for Fill,fill_or_stroke, or STROKE

*

* SETSTROKECAP (Paint.cap Cap);

* When the brush style is stroke or fill_or_stroke, set the brush's graphic style, such as the circle style

* Cap.round, or square style Cap.square

*

* Setsrokejoin (Paint.join Join);

* Set how the shapes are combined when drawing, such as smoothing effects, etc.

*

* Setstrokewidth (float width);

* When the brush style is stroke or fill_or_stroke, set the thickness of the brush

*

* Setxfermode (Xfermode xfermode);

* Set the process of drawing overlap, such as merging, taking intersection or union, often used to make eraser effect.

*

* 2. Text rendering

* Setfakeboldtext (Boolean fakeboldtext);

* Simulation to implement bold text, set in small font effect will be very poor

*

* Setsubpixeltext (Boolean subpixeltext);

* Setting this to True will help to display the text on the LCD screen

*

* SetTextAlign (paint.align Align);

* Set the alignment direction of the drawing text

*

* Settextscalex (float ScaleX);

* Set the scale of the drawing text x axis, can achieve the effect of the text stretching

*

* Settextsize (float textSize);

* Set font size for drawing text

*

* SETTEXTSKEWX (float skewx);

* Set italic text, skewx to oblique radians

*

* Settypeface (Typeface Typeface);

* Set typeface object, that is, font style, including bold, italic and liner body, non-liner body, etc.

*

* Setunderlinetext (Boolean underlinetext);

* Set underlined text effects

*

* Setstrikethrutext (Boolean strikethrutext);

* Set the effect with strikethrough

*
