I saw that there was a similar question but my problem is not the same :
This is how I create my graphicLines :
var myArr = [
[x1, y1],
[x2, y2],
...
]
// Get the active document
var doc = app.activeDocument;
// Get item from the page
var page = doc.pages.item(0);
var line = page.graphicLines.add();
line.paths.item(0).entirePath = myArr;
I should have this (the line circled in blue) :
But I get this (the rectangle circled in blue) :
This rectangle appears when I click on the focus, otherwise it is nonexistent.
The rectangle seems to be the size of the line and is well positioned but I did not get the line I wanted. What did I forget ?
Try to add this line at the end of your snippet:
line.strokeWeight = 1;

I'd like to extract the "col" color value from this function to be used to paint plots or candle colors. But everything I try creates one error or another. I checked the Script Reference. Shouldn't there be some way to "return" a value, as is usually the case with most functions?
lset(l,x1,y1,x2,y2,col)=>
line.set_xy1(l,x1,y1)
line.set_xy2(l,x2,y2)
line.set_width(l,5)
line.set_style(l, line.style_solid)
line.set_color(l,y2 > y1 ? #ff1100 : #39ff14) //red : green
temp = line.get_price(l,bar_index) // another value to extract
The documentation is showing it like this:
line.new(x1, y1, x2, y2, xloc, extend, color, style, width) → series line
So in your code it's looking differently and also the "new" is missing.
Scrolling a bit up on the linked page shows that there exist indeed methods to retrieve some properties of the line object:
Lines are managed using built-in functions in the line namespace. They include:
line.new() to create them.
line.set_*() functions to modify the properties of an line.
line.get_*() functions to read the properties of an existing line.
line.copy() to clone them.
line.delete() to delete them.
The line.all array which always contains the IDs of all
the visible lines on the chart. The array’s size will depend on
the maximum line count for your script and how many of those you
have drawn. aray.size(line.all) will return the array’s size.
The most simple usage is to instantiate a line object with the correct values directly, like shown here:
//#version=5
indicator("Price path projection", "PPP", true, max_lines_count = 100)
qtyOfLinesInput = input.int(10, minval = 1)
y2Increment = (close - open) / qtyOfLinesInput
// Starting point of the fan in y.
lineY1 = math.avg(close[1], open[1])
// Loop creating the fan of lines on each bar.
for i = 0 to qtyOfLinesInput
// End point in y if line stopped at current bar.
lineY2 = open + (y2Increment * i)
// Extrapolate necessary y position to the next bar because we extend lines one bar in the future.
lineY2 := lineY2 + (lineY2 - lineY1)
lineColor = lineY2 > lineY1 ? color.lime : color.fuchsia
line.new(bar_index - 1, lineY1, bar_index + 1, lineY2, color = lineColor)
Getting the line color from outside is difficult or impossible though as there never exists a method to retrieve it while for other properties those methods exist.
So the most simple way is to create the same funcionality, to get the color that exists inside the line-object, outside too, or only outside.
currentLineColor = y2 > y1 ? #ff1100 : #39ff14
You could try to extend the line-object somehow like this:
line.prototype.get_color = function() {
return this.color;
};
console.log(line.get_color())
I'm not sure if the approach with the prototype is working but it's worth it to try if you need it.
I wonder how to set the text "Highlight" of a part of text inside tlfTextField with the code?
I tried "tf.backgroundColor = 0x990000" property, but did not help.
For instance, I can change the Font Color of any contents inside Parenthesis, by this code:
private function decorate():void {
var tf:TextFormat = new TextFormat();
tf.color = 0x990000;
var startPoint:int = 0;
while (startPoint != -1) {
var n1:int = textMc.tlfText.text.indexOf("(", startPoint);
var n2:int = textMc.tlfText.text.indexOf(")", n1 + 1);
if (n1 == -1 || n2 == -1) {
return;
}
textMc.tlfText.setTextFormat(tf, n1 + 1, n2);
startPoint = n2 + 1;
}
}
So I know "tf.color = 0x990000;" will change the Font color, however, don't know how to "highlight" some text, with code, as I do inside Flash manually.
You should have probably used tlfMarkup property to set the required format to the specific part of text. The attributes you seek are backgroundColor and backgroundAlpha of the span XML element that you should wrap your selection, however it should be much more difficult should there already be spans around words when you retrieve the property from your text field.
The problem with your solution is that you don't check if the two characters are located on a single line before drawing your rectangle, also you would need to redraw such rectangles each time something happens with the textfield. The proposed approach makes use of Flash HTML renderer's capabilities to preserve the formatting, however it will require a lot of work to handle this task properly.
I want to replace a word "allowance" with "Some text", after running the code, It will remove word allowance and apply "Some text" with same formatting as that of "allowance" but foreground color property is not getting set as that of original.I want Some text also in red color as shown in the screenshot
function retainFormatting() {
var doc = DocumentApp.getActiveDocument();
var textToHighlight = 'allowance';
var highlightStyle;
var paras = doc.getParagraphs();
var textLocation = {};
var i;
for (i=0; i<paras.length; ++i) {
textLocation = paras[i].findText(textToHighlight);
if (textLocation != null && textLocation.getStartOffset() != -1) {
highlightStyle = textLocation.getElement().getAttributes(textLocation.getStartOffset());
textLocation.getElement().deleteText(textLocation.getStartOffset(),textLocation.getEndOffsetInclusive());
textLocation.getElement().insertText(textLocation.getStartOffset(),"Some text");
textLocation.getElement().setAttributes(textLocation.getStartOffset(),textLocation.getEndOffsetInclusive(), highlightStyle);
}
}
}
before setting attribute at offset
after setting attribute it turns out to be
getForegroundColor(offset)
Retrieves the foreground color at the specified character offset.
And
setForegroundColor(startOffset, endOffsetInclusive, color)
Sets the foreground color for the specified character range.
Here is a sample code :
Getting Color from text
highlightColor = textLocation.getElement().getForegroundColor(textLocation.getStartOffset());
Applying color to text
textLocation.getElement().setForegroundColor(textLocation.getStartOffset(),textLocation.getEndOffsetInclusive(), highlightStyle);
I hope it helps. Goodluck :)
Try
textLocation.getElement().editAsText().deleteText(textLocation.getStartOffset(),textLocation.getEndOffsetInclusive());
textLocation.getElement().editAsText().insertText(textLocation.getStartOffset(),"Some text");
The .editAsText() puts you into editing the contents of the rich text leaving the existing attributes as a 'wrapper'
Alternatively, try replacing the text rather than deleting and inserting
paras[i].replaceText("allowance", "some text") // the first attribute is a regular expression as string
I have just tested this and it seems that setting LINK_URL alongside other attributes interferes with FOREGROUND_COLOR.
The following results in a black text color:
var attrs = {
"FOREGROUND_COLOR": "#ff0000", // should be red
"LINK_URL": null
};
text.setAttributes(start, end, attrs);
The following results in a red text color:
var attrs = {
"FOREGROUND_COLOR": "#ff0000" // should be red
};
text.setAttributes(start, end, attrs);
In effect, if you don't need to set the link, remove the LINK_URL from the list of formatting options.
#JSDBroughton Gave me an idea, which worked.
Try setting the attributes of the rich text object you get when calling editAsText. So instead of:
highlightStyle = textLocation.getElement().getAttributes(textLocation.getStartOffset());
textLocation.getElement().setAttributes(textLocation.getStartOffset(),textLocation.getEndOffsetInclusive(), highlightStyle);
Do:
// Make sure you replace `asParagraph` with what you actually need
highlightStyle = textLocation.getElement().asParagraph().editAsText().getAttributes(textLocation.getStartOffset());
textLocation.getElement().asParagraph().editAsText().setAttributes(textLocation.getStartOffset(),textLocation.getEndOffsetInclusive(), highlightStyle);
Edit: after playing around with this, seems like this only sometimes works. I still haven't figured out the pattern for when it does work and when it doesn't.
I am trying to mask an image on another so that I only view the specific portion of the unmasked image through the masked one. My problem is that I cannot see anything on the screen.. no Image, no effect at all
cardMask = new Image(Root.assets.getTexture("card_mask"));
cardMask.y = Constants.STAGE_HEIGHT*0.40;
cardMask.x = Constants.STAGE_WIDTH *0.48;
trace("it's add mask");
cardLight = new Image(Root.assets.getTexture("card_light_mask"));
cardLight.y = Constants.STAGE_HEIGHT*0.46;
cardLight.x = Constants.STAGE_WIDTH *0.48;
cardLight.mask=cardMask;
maskedDisplayObject = new PixelMaskDisplayObject(-1,false);
maskedDisplayObject.addChild(cardLight);
maskedDisplayObject.x=cardLight.x;
maskedDisplayObject.y=cardLight.y;
maskedDisplayObject.mask=cardMask;
maskedDisplayObject.blendMode = BlendMode.SCREEN;
addChild(maskedDisplayObject);
First, for masking an object the mask object should also be added to the display list. Your code does not add cardMask to display list anywhere. Second, if your maskedDisplayObject should be visible at all times, the mask should be assigned not to it, but to some other object which displayed part you desire to control. And third, it is also possible that this.stage is null, therefore the entire tree (this -> maskedDisplayObject -> cardLight) is plain not rendered. You need to check all three of these conditions to get something displayed.
Also, if you desire cardLight as an object to move independently of maskedDisplayObject, you should add it to this instead, and check that it's displayed on top of maskedDisplayObject (call addChild(cardLight) after addChild(maskedDisplayObject)).
This all totals to this code:
trace("Stage is null:", (this.stage==null)); // if this outputs true, you're out of display
cardMask = new Image(Root.assets.getTexture("card_mask"));
cardMask.y = Constants.STAGE_HEIGHT*0.40;
cardMask.x = Constants.STAGE_WIDTH *0.48; // mask creation unaltered
trace("it's add mask");
cardLight = new Image(Root.assets.getTexture("card_light_mask"));
cardLight.y = Constants.STAGE_HEIGHT*0.46;
cardLight.x = Constants.STAGE_WIDTH *0.48;
cardLight.mask=cardMask; // this is right
maskedDisplayObject = new PixelMaskDisplayObject(-1,false);
// maskedDisplayObject.addChild(cardLight); this is moved to main part of display list
maskedDisplayObject.x=cardLight.x;
maskedDisplayObject.y=cardLight.y;
// maskedDisplayObject.mask=cardMask; NO masking of this, you're only masking cardLight
cardLight.blendMode = BlendMode.SCREEN; // display mode is also changed
addChild(maskedDisplayObject);
addChild(cardLight);
I got the following question.
i added the following elements to the stage:
homeBg = new HomeBg();
homeMask = new HomeDrawBg();
addChild(homeBg);
addChild(homeMask);
I allready instantiated them in the beginning of the document. But my problem is the following. the homeBg layer is a image, the homeMask layer is the same image but it has a pencil scetch look. What i want is that wherever i move my mouse, the homemask layer should be erased so the bottom layer becomes visible(only where the mask is erased). So how can i tell the mask layer to erase itself if the mouse is over it?
Answer attempt 2
You can use the blendMode property of a display object to achieve this. Here's the code (tested):
// set the eraser width (diameter)
var eraserWidth:int = 20;
//get the HomeMask library item
var homeMask:HomeMask = new HomeDrawBg();
homeMask.blendMode = BlendMode.LAYER;
addChild(homeMask);
// create the eraser shape
var eraser:Shape = new Shape();
eraser.graphics.beginFill(0x000000);
eraser.graphics.drawCircle(0,0,eraserWidth/2);
eraser.blendMode = BlendMode.ERASE;
homeMask.addChild(eraser);
homeMask.addEventListener(MouseEvent.MOUSE_MOVE,mouseOverMask);
function mouseOverMask(evt:MouseEvent):void
{
eraser.x = homeMask.mouseX;
eraser.y = homeMask.mouseY;
}
There are a couple of important bits here.
Firstly, you must set the blendMode of the thing you want to erase to BlendMode.LAYER.
Secondly (and this is what has tricked me before) your eraser, with BlendMode.ERASE, must be a child of the object you're wanting to erase.
