How to rotate SmartArtNode text aspose.slide
I use:
tmNode.TextFrame.TextFrameFormat.RotationAngle = 90
But it's not working
I have observed your requirements and suggest you to please try using Aspose.Slides for.NET 17.1.0 using following sample code. I am able to observe the rotation effect on text. I hope this will be helpful. You may also contact us in Aspose.Slides forums if there is any further inquiry.
using (Presentation presentation = new Presentation())
{
// Accessing the slide
ISlide slide = presentation.Slides[0];
// Adding SmartArt shape and nodes
var chevron = slide.Shapes.AddSmartArt(10, 10, 800, 60, SmartArtLayoutType.ClosedChevronProcess);
var node = chevron.AllNodes.AddNode();
node.TextFrame.Text = "Some text";
node.TextFrame.TextFrameFormat.RotationAngle = 90;
// Saving Presentation
presentation.Save(dataDir + "FillFormat_SmartArt_ShapeNode_out.pptx", SaveFormat.Pptx);
}

Question is quite simple but unfortunately, i am not able to find solution.
I am trying to add watermark in pdf page. here is the code.
$mpdf->SetDisplayMode('fullpage');
$mpdf->SetWatermarkText('DRAFT');
$mpdf->watermarkTextAlpha = 0.081;
$mpdf->watermark_font = 'DejaVuSansCondensed';
$mpdf->showWatermarkText = true;
$mpdf->WriteHTML($html);
Above code work fine but size of Watermark is quite big.
I want to make it smaller.
I read the documentation but didn't found fontsize for watermark.
I set the watermark fontsize by modifying watermark function in mpdf.php:
Example:
function watermark($texte, $angle = 45, $fontsize = 120, $alpha = 0.2) {
$fontsize = 24
}
I saw this site :http://www.leeroy.ca/ and I would love to know how they make the interaction on the first page can someone give me a hint thanks!
This can be done using Canvas. The plugin they have used is called ParticleSlider. This is a commercial plugin, which needs licence to use, and it can be initialized using the following code:
// Create a new Particle
var ps = new ParticleSlider();
var ptl = new ps.Particle(ps);
Or the other one is:
// Create a 100px wide ParticleSlider.
var ps = new ParticleSlider({
width: 100
});
// Create a ParticleSlider with default width
// and change width to 100px.
var ps = new ParticleSlider();
ps.width = 100;
In a drag+drop situation using Flex, I am trying to get the object center aligned to the point of drop- somehow, irrespective of the adjustments to height and width, it is always positioning drop point to left top.
here is the code..
imageX = SkinnableContainer(event.currentTarget).mouseX;
imageY = SkinnableContainer(event.currentTarget).mouseY;
// Error checks if imageX/imageY dont satisfy certain conditions- move to a default position
// img.width and img.height are both defined and traced to be 10- idea to center image to drop point
Image(event.dragInitiator).x = imageX-(img.width)/2;
Image(event.dragInitiator).y = imageY-(img.height)/2
The last 2 lines don't seem to have any effect. Any ideas why-must be something straightforward, that I am missing...
You can use the following snippet:
private function on_drag_start(event:MouseEvent):void
{
var drag_source:DragSource = new DragSource();
var drag_initiator:UIComponent = event.currentTarget as UIComponent;
var thumbnail:Image = new Image();
// Thumbnail initialization code goes here
var offset:Point = this.localToGlobal(new Point(0, 0));
offset.x -= event.stageX;
offset.y -= event.stageY;
DragManager.doDrag(drag_initiator, drag_source, event, thumbnail, offset.x + thumbnail.width / 2, offset.y + thumbnail.height / 2, 1.0);
}
Here is one important detail. The snippet uses stage coordinate system.
If you use event.localX and event.localY, this approach will fail in some cases. For example, you click-and-drag a movie clip. If you use localX and localY instead of stage coordinates, localX and localY will define coordinates in currently clicked part of the movie clip, not in the whole movie clip.
Use the xOffset and yOffset properties in the doDrag method of DragManager.
Look here for an example.
I have a game with a big raster map
Now we are using jpeg (4900x4200)
And durring the game we need to scroll through this map.
We use the following:
Class Map extends mx.containers.Canvas
and mx.controls.Image on it
In constructor we have:
public function Map() {
super();
image.source = ResourceManager.interactiveManager.map;//big image
addChild(image);
......
}
for scrolling we are use:
if(parentAsCanvas==null){
parentAsCanvas = (parent as Canvas);
}
parentAsCanvas.verticalScrollPosition = newX;
parentAsCanvas.horizontalScrollPosition = newY;
In windows, we have very good performance.
In Linux and Mac in flashplayer we have a good performance too.
But in browsers performance is quite slow!
What can we do to resolve it?
It's slow because you're rendering a large image all the time.
Here are a few things that cross my mind:
Try using the scrollRect property in a Bimtap object holding your image BitmapData to display just the visible area then use the scrollRect x and y to move to a new region
Try using a BitmapData the size of the viewable area and use copyPixels() to get the right area to display, again using a rectangle
Try using BitmapData.scroll()
Here are a few snippets:
scrollRect:
//assuming map is BitmapData containing your large image
//100x100 is a test scroll area
var scroll:Rectangle = new Rectangle(0,0,100,100);
var bitmap:Bitmap = new Bitmap(map);
bitmap.scrollRect = scroll;
addChild(bitmap);
this.addEventListener(Event.ENTER_FRAME, update);
function update(event:Event):void{
scroll.x = mouseX;
scroll.y = mouseY;
bitmap.scrollRect = scroll;
}
copyPixels:
var scroll:Rectangle = new Rectangle(0,0,100,100);
var scrollPoint:Point = new Point();
var map:BitmapData = new Map(0,0);
var bitmap:Bitmap = new Bitmap(new BitmapData(100,100,false));
bitmap.bitmapData.copyPixels(map,scroll,scrollPoint);
addChild(bitmap);
this.addEventListener(Event.ENTER_FRAME, update);
function update(event:Event):void{
scroll.x = mouseX;
scroll.y = mouseY;
bitmap.bitmapData.fillRect(scroll,0xFFFFFF);
bitmap.bitmapData.copyPixels(map,scroll,scrollPoint);
}
Not perfect, but it should give you an idea
HTH,

I've read the following acrticle http://www.insideria.com/2008/04/flex-ria-performance-considera.html
I and i found the resolve of my problem.
If i open my SWF in browser as "http://host/myswf.swf" I have huge performance lose in browser as the reason work LaoyoutManager, that recalculates positions and sizes of all canvases in the application. And it process eats more than 60% of performance capacity.(Yep, we have a lot of Canvases in our application).
And when i putted my application in contant-size html block in html page, all problems were go away! I've got 80% performance increase!
I'm working with Flex 3.4 SDK.
I'm trying to programmatically(yep, must be this way) style/skin a VBox so that its top right corner is rounded, and it gets a two colors gradient brackground.
Modifying examples I found around I was able to accomplish both effects(corner and background) but only separately:
VBox with not all rounded corners: http://livedocs.adobe.com/flex/3/html/help.html?content=skinning_6.html
VBox with gradient background: http://butterfliesandbugs.wordpress.com/2007/06/08/generic-background-gradient-for-containers/
But what I need to do is to apply both at the same time. And all my coding attempts so far have failed silently.
Would anyone know how to go about doing this correctly?
I have a post on my blog on how to make this exact component Here.
You create a basic custom MXML component (extending in this case, VBox). You specify a programmatic skin, which is where the bevel and gradient gets applied.
The programmatic skin does all it's drawing in the updateDisplayList function.
Here is some of the code (the rest is on my blog, with a demo)
var g:Graphics = graphics;
var cn:Number = this.getStyle("cornerRadius");
var crtl:Number = this.getStyle("cornerRadiusTopLeft") > 0 ? this.getStyle("cornerRadiusTopLeft") : cn;
var crtr:Number = this.getStyle("cornerRadiusTopRight") > 0 ? this.getStyle("cornerRadiusTopRight") : cn;
var crbl:Number = this.getStyle("cornerRadiusBottomLeft") > 0 ? this.getStyle("cornerRadiusBottomLeft") : cn;
var crbr:Number = this.getStyle("cornerRadiusBottomRight") > 0 ? this.getStyle("cornerRadiusBottomRight") : cn;
var gradFrom:Number = this.getStyle("gradientFrom");
var gradTo:Number = this.getStyle("gradientTo");
var b:EdgeMetrics = borderMetrics;
var w:Number = unscaledWidth - b.left - b.right;
var h:Number = unscaledHeight - b.top - b.bottom;
var m:Matrix = verticalGradientMatrix(0, 0, w, h);
g.clear();
g.beginGradientFill("linear", [gradFrom, gradTo], [1, 1], [0, 255], m);
g.lineStyle(1,borderColor,1,true,LineScaleMode.NORMAL,CapsStyle.ROUND,JointStyle.ROUND);
GraphicsUtil.drawRoundRectComplex(g, b.left, b.top, w, h, crtl, crtr, crbl, crbr);
g.endFill();
}
for a demo, look Here. Hope this helps.
Follow the steps from your second link, but instead of using "drawRect", you should be able to use "drawRoundRectComplex". You may need to play around with some of the matrix settings though. I seem to remember having some problems.
Another option is to use degrafa. There can be a bit of a learning curve, but it's powerful and can do this.
