Actionscript :: Clear Just A Portion Of A Graphics Object?

May 10, 2011

I am making a Flash CS5 application in which the user draws transparent overlays on a Sprite placed on top of an image. The user needs to be able to erase his input as in MS Paint, Adobe Photoshop, or GIMP. Because the Sprite is on top of an image, there is no safe clear color I can think of to draw over the section that the user has just rubbed his eraser over

ActionScript 3.0 :: Graphics Clear() Doesn't Clear Bitmap Data From BeginBitmapFill()?

Jul 30, 2011

I'm working on a game whose background has many layers that each scroll at different speeds.

Inside each layer I have a Sprite, I've started using graphics.beginBitmapFill, but what I've found is that the graphics.clear() function doesn't actually clear the contents set by the previous call to graphics.begin.BitmapFill. Each frame, I adjust the matrix to shift the layer as needed.  Then, I call graphics.clear() and graphics.beginBitmapFill() with the adjusted matrix. Since my layers have alphas in the bitmap, I can see the contents that was drawn the previous frame.

Actionscript 3 :: Using Graphics.clear Not Working As Expected?

Mar 12, 2012

Would anyone know why using graphics.clear(); in this example is preventing the graphics from being drawn?

e.g. the following code works and the lines are drawn.

var my_shape:Shape = new Shape();
my_shape.graphics.lineStyle(2, 0x00FF00, 1);
addChild(my_shape);

[Code]....

I'm wanting to animate the line moving so would like to clear the previous drawing before redrawing the lines.

ActionScript 3.0 :: Visual Artifacts Left After Graphics.clear?

Feb 2, 2010

I am drawing an animated angled line. The line follows a (senocular) path and updates using TweenMax. The line draws in and then 'retreats' out again. When the line retreats, I am left with 'chips' from the line graphic - even though I have used sprite.graphics.clear().

An example is will be clearer so I have uploaded one here:[URL]Allow the grey line to draw in and the red button to appear. Roll over and out the red button and you should see the small triangle artefacts from the highlighting left behind on the angle.I created a simplified?! version of the code in the hope that someone can point out an error:

EDIT: If I change the JointStyle to MITER in lineStyle, that fixes it but I am non the wiser and would prefer to use ROUND. END EDIT

Code:
package
{
import com.senocular.drawing.Path;
import flash.display.*;
import flash.events.*;

Flex :: Set Text On A Graphics Object?

Oct 19, 2011

Is there anyway I can effectively call the equiv. of setText on a Flex Graphics object ?Specifically I'm using a custom cell renderer to display data in a datagrid. The renderer uses the Graphics object to set the background colour of only a portion of the cell (say the left half) based upon the underlying data. I would like to be able to have text over only that portion of the cell which has the background colour (eg centred within the left half). I know all the widths (of both the cell itself and the graphics object) but I don't know how I can set text (centred) over the graphics object.

however this does not work.   I've RTFM'd but can't figure out exactly how to deal with the Graphics object.

ActionScript 3.0 :: Calling Graphics In Custom Object?

Dec 14, 2011

I am trying to create a custom object which will display particular graphics at a particular time (when the movie tells the object to show something). Well I made my object (the way I thought it would work) and I encountered a problem when I called graphics functions from the main movie.

I made a very stripped down version of the same object to test and see what was going wrong. Apparently, I can call "Draw()" directly from inside the constructor and it will use the draw methods, but I cannot call it from the movie (like in the script below) and I can't call it from another function in the object if that function is not called during the constructor.

The question is... am I doing this right? The simple version of my end goal would be to create this object and have a function that I can call in the object something like "DrawImage(imagePath:String)" and it will use the graphics to draw the image.

In the movie:

Flash - Draw A Bitmap In Graphics-Object At Any Position?

Mar 30, 2011

Is it possible to draw a Bitmap to a Graphics-Object like

this.graphics.beginBitmapFill(bitmapData, matrix, false);
this.graphics.drawRect(0, 0, w, h);
this.graphics.endFill();

with an offset?

A simple moveTo(x, y) call before beginBitmapFill does not work :/ Neither does changing the x and y value of drawRect... (That just seems to have the same effect as an translation with the matrix...) Additionally I don't want do draw that thing in a separate Graphics-Object and add that one into the other...

Flex :: Graphics - Filling Color In An Object Built Using Primitives

Apr 22, 2011

I have a bounded object, created using primitives lines in Action Script- either an oval or a triangle. Is there any way I can fill the contents in a specific color

Just to clarify on this- the shape could be in two ways

a) drawing a isoceles triangle based on a variable apex angle

b) two curved lines to form a "lens"

I am not sure if I can use the fill function, as I am not drawing a inherently bounded shape- the closed nature is based on my calculations
