Setting the z-index of loader class - ios

I'm working in Flash AS3, AIR 3.2 for iOS SDK. I'm loading in an image, then applying a shape and textfield over this. But it seems that z-index goes weird with the loader class. At the moment, when this is run, the text and shape is applied first, and the image then gets applied on top of these even though the methods are in a different order. How do I set the shape and text to be above an image that's loaded in from the loader class?
The methods in the main method:
displayImage();
overlayBox();
textAnimation();
These are the methods:
public function displayImage():void {
var imageurl:String = "image.jpg";
myLoader = new Loader();
var fileRequest:URLRequest = new URLRequest(imageurl);
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoaderProgress);
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderComplete);
myLoader.load(fileRequest);
}
public function onLoaderProgress(e:ProgressEvent) {
trace(e.bytesLoaded, e.bytesTotal); // this is where progress will be monitored
}
public function onLoaderComplete(e:Event) {
image = new Bitmap(e.target.content.bitmapData);
var imageWidth:Number = image.width;
var imageHeight:Number = image.height;
var resizeWidthVar:Number;
var resizeHeightVar:Number;
trace("Image width: " + image.width);
trace("Image height: " + image.height);
if(imageWidth >= imageHeight) {
resizeHeightVar = imageHeight/displayRes;
trace("resizeHeightVar = " + resizeHeightVar);
imageWidth = imageWidth/resizeHeightVar;
imageHeight = imageHeight/resizeHeightVar;
}
else {
resizeWidthVar = imageWidth/displayRes;
trace("resizeWidthVar = " + resizeWidthVar);
imageWidth = imageWidth/resizeWidthVar;
imageHeight = imageHeight/resizeWidthVar;
}
image.width = imageWidth;
image.height = imageHeight;
trace("Image width: " + image.width);
trace("Image height: " + image.height);
image.x = xScreenPos;
image.y = yScreenPos;
addChild(image); // the image is now loaded, so let's add it to the display tree!
}
public function overlayBox():void {
var overlaySquare:Sprite = new Sprite();
addChild(overlaySquare);
overlaySquare.graphics.beginFill(0x00000, 0.7);
overlaySquare.graphics.drawRect(0, 0, displayRes, displayRes);
overlaySquare.graphics.endFill();
overlaySquare.x = xScreenPos;
overlaySquare.y = yScreenPos;
}
public function textAnimation():void {
//set text format
textFormat.font = "Helvetica Neue Light";
textFormat.size = 12;
textFormat.bold = false;
textFormat.color = 0x000000;
// pass text format
textOne.defaultTextFormat = textFormat;
textOne.text = "Blah blah blah blah";
textOne.autoSize = TextFieldAutoSize.LEFT;
textOne.x = xScreenPos;
textOne.y = yScreenPos;
//add to stage
addChild(textOne);
}

One of the solutions is to replace addChild(image); with the addChildAt(image, 0); another one is to add loader addChild(loader); and don't add image in the complete handler.

How to add watermark to aspose pdf and word that contain table

I generate a Aspose.Generate.Pdf file and then add a Aspose.Pdf.Generator.Tableto it by following method. but when I add watermark to this pdf file, it covers by created table:
public static BasketResult<string> ExportDataTableToPdf(DataTable inputDataTable, string CaptionFilename)
{
List<DataColumn> listDataColumns = GetDataColumns(inputDataTable, CaptionFilename);
BasketResult<string> returnResult = new BasketResult<string>();
String rtnPathFile = String.Empty;
int rowCount = inputDataTable.Rows.Count;
if (rowCount <= 1000)
{
try
{
string dataDir = Settings.TempPath;
if (!Directory.Exists(dataDir))
Directory.CreateDirectory(dataDir);
Pdf pdfConv = new Pdf();

// header definition begin
Aspose.Pdf.Generator.HeaderFooter header = new Aspose.Pdf.Generator.HeaderFooter(mainSection);
mainSection.EvenHeader = header;
mainSection.OddHeader = header;
header.Margin.Top = 50;
Aspose.Pdf.Generator.Table headerTable = new Aspose.Pdf.Generator.Table();
header.Paragraphs.Add(headerTable);
headerTable.DefaultCellBorder = new BorderInfo((int)BorderSide.All, 0.1F);
headerTable.Alignment = AlignmentType.Right;
headerTable.DefaultColumnWidth = "80";
headerTable.FixedHeight = 30;
Aspose.Pdf.Generator.Row headerRow = headerTable.Rows.Add();

}
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Aspose.Words.Tables.Table wordTable = ImportTableFromDataTable(builder, inputDataTable,
CaptionFilename, true);
string columnWidths = "";
for (int j = 0; j < wordTable.FirstRow.Count; j++)
{

? new Aspose.Pdf.Generator.Color("#D3DFEE")
: new Aspose.Pdf.Generator.Color("#FFFFFF");
var wordTableRow = wordTable.Rows[i];
//fill columns from end to begin because table is left to right
for (int c = wordTable.FirstRow.Count - 1; c >= 0; c--)
{
var cellValue = wordTableRow.ChildNodes[c];
string cellText = cellValue.GetText();
row.Cells.Add(cellText);
}
//set style to every cell
for (int c = 0; c < wordTable.FirstRow.Count; c++)
{
row.Cells[c].DefaultCellTextInfo.FontName = "Tahoma";
row.Cells[c].DefaultCellTextInfo.IsRightToLeft = true;

}
}
pdfConv.SetUnicode();
rtnPathFile = Helper.GetTempFile() + ".pdf";
string fileName = Helper.GetFileNameFromFilePath(rtnPathFile);
pdfConv = AddPdfWatermark(pdfConv);

}
return returnResult;
}
and AddPdfWatermerk method is :
private static Pdf AddPdfWatermark(Aspose.Pdf.Generator.Pdf pdfConv)
{
try
{
// Create FloatingBox with x as width and y as height
Aspose.Pdf.Generator.FloatingBox background = new Aspose.Pdf.Generator.FloatingBox(); // width, height
Aspose.Pdf.Generator.Image backImage = new Aspose.Pdf.Generator.Image();
string path = HttpContext.Current.Server.MapPath("~/images/PrivateExcelBackGround.png");
byte[] bgBuffer = File.ReadAllBytes(path);
MemoryStream streamBack = new MemoryStream(bgBuffer, false);
backImage.ImageInfo.ImageStream = streamBack;
background.Paragraphs.Add(backImage);
background.ZIndex = 1000;
pdfConv.Watermarks.Add(background);
pdfConv.IsWatermarkOnTop = false;
return pdfConv;
}
catch
{
return pdfConv;
}
}
I tried stamp instead of watermark, but table masks it too.
in aspose.words.document file I have a problem too, in word file with mentioned table,watermark added correctly but when a colored alternate table rows, watermark covered by colorful rows.
You are using an out-dated version of Aspose.PDF API. Kindly upgrade to Aspose.PDF for .NET 18.1, which includes more features and bug fixes. You can add an image stamp by using below code snippet in your environment.
// Open document
Document pdfDocument = new Document(dataDir+ "AddImageStamp.pdf");
// Create image stamp
ImageStamp imageStamp = new ImageStamp(dataDir + "aspose-logo.jpg");
imageStamp.Background = true;
imageStamp.XIndent = 100;
imageStamp.YIndent = 100;
imageStamp.Height = 300;
imageStamp.Width = 300;
imageStamp.Rotate = Rotation.on270;
imageStamp.Opacity = 0.5;
// Add stamp to particular page
pdfDocument.Pages[1].AddStamp(imageStamp);
dataDir = dataDir + "AddImageStamp_out.pdf";
// Save output document
pdfDocument.Save(dataDir);
ImageStamp class provides the properties necessary for creating an image-based stamp, such as height, width, opacity etc. You may visit Adding stamp in a PDF file for further information on this topic. In case you notice any problem with the file generated by using this code, please get back to us with source and generated file so that we may proceed to help you out.

How to setup Flot for iOS retina display

I have tested this on an iPad (3 generation). The line chart appears perfectly smooth.
http://justindarc.github.com/flot.touch/example/index.html
I have tried diffing the code with my flot code and cannot see any significant difference that would cause it to run in retina mode. My flot is version 0.7, same as his code. No matter what I try my own chart runs in non-retina mode.
What is the trick in running retina mode?
My setup code is rather long.
function setup_chart0(setup_options) {
var point_data = [];
if(setup_options.use_sample_data_for_chart0) {
point_data = generate_dummy_data(
setup_options.timestamp_generate_min,
setup_options.timestamp_generate_max
);
}
var average_data = henderson23(point_data);
var datasets = make_chart0_datasets(point_data, average_data);
if(is_dualaxis_detail_mode) {
datasets = make_chart0_dual_datasets(
[],
[],
[],
[]
);
}
var options = default_plot_options();
options.xaxis.min = setup_options.timestamp_visible_min;
options.xaxis.max = setup_options.timestamp_visible_max;
options.xaxis.panRange = [setup_options.timestamp_pan_min, setup_options.timestamp_pan_max];
options.yaxis.min = -0.025;
options.yaxis.max = 1.025;
options.yaxis.panRange = [-0.025, 1.025];
options.legend = { container: '#legend0', noColumns: 2 };
options.grid.markings = compute_markings_with_alertlevels;
if(is_dualaxis_detail_mode) {
options.y2axis = {};
options.y2axis.position = "right";
options.y2axis.min = -0.025;
options.y2axis.max = 1.025;
options.y2axis.panRange = [-0.025, 1.025];
options.legend = { container: '#legend_hidden', noColumns: 2 };
}
//save_as_file({ samples: point_data, average: average_data });
var el_placeholder0 = $("#placeholder0");
if(el_placeholder0.length){
//console.log('plotting chart 0');
var fade = false;
var el = el_placeholder0;
var el_outer = $("#placeholder0_outer");
var original_offset = el_outer.offset();
if(fade) {
el_outer.offset({ top: -5000, left: 0 }); // move plot container off screen
}
chart0 = $.plot(el, datasets, options);
if(fade) {
el.hide(); // hide plot - must do *after* creation
el_outer.offset(original_offset); // put plot back where it belongs
el.fadeIn('slow'); // fade in
}
/*var s = ' width: ' + chart0.width() + ' height: ' + chart0.height();

});
}
}
}
I have modified jquery.flot.js like this:
In the top I have added
retinaMode = (window.devicePixelRatio > 1),
I have extended these functions
function makeCanvas(skipPositioning, cls) {
var c = document.createElement('canvas');
c.className = cls;
c.width = canvasWidth;
c.height = canvasHeight;
if (!skipPositioning)
$(c).css({ position: 'absolute', left: 0, top: 0 });
$(c).appendTo(placeholder);
if(retinaMode) {
c.width = canvasWidth * 2;
c.height = canvasHeight * 2;
c.style.width = '' + canvasWidth + 'px';
c.style.height = '' + canvasHeight + 'px';
}
if (!c.getContext) // excanvas hack
c = window.G_vmlCanvasManager.initElement(c);
// used for resetting in case we get replotted
c.getContext("2d").save();
if (retinaMode) {
c.getContext("2d").scale(2,2);
}
return c;
}
function getCanvasDimensions() {
canvasWidth = placeholder.width();
canvasHeight = placeholder.height();
if (canvasWidth <= 0 || canvasHeight <= 0)
throw "Invalid dimensions for plot, width = " + canvasWidth + ", height = " + canvasHeight;
}
function resizeCanvas(c) {
// resizing should reset the state (excanvas seems to be
// buggy though)
if (c.width != canvasWidth) {
c.width = canvasWidth;
if(retinaMode) {
c.width = canvasWidth * 2;
}
c.style.width = '' + canvasWidth + 'px';
}
if (c.height != canvasHeight) {
c.height = canvasHeight;
if(retinaMode) {
c.height = canvasHeight * 2;
}
c.style.height = '' + canvasHeight + 'px';
}
// so try to get back to the initial state (even if it's
// gone now, this should be safe according to the spec)
var cctx = c.getContext("2d");
cctx.restore();
// and save again
cctx.save();
if(retinaMode) {
cctx.scale(2, 2);
}
}

OOXML : keep images displayed after moving the header content to to the body

I am using open XML SDK and I want to move the content of content control (containing images) from the header to the body, the problem that images does not show after moving. After copying the content control content I am adding the image parts in this way :
foreach (var headerPart in wordDocument.MainDocumentPart.HeaderParts)
{
SdtBlock sdtToSave = this.FindSdtBlock(contentControlTag, headerPart );
if (sdtToSave != null)
{
foreach (var imagePart in headerPart.ImageParts)
{
ImagePart newPart = mainPart.AddImagePart(imagePart.ContentType);
this.GenerateImagePartContent(newPart, imagePart.GetStream()); }
}
}
private void GenerateImagePartContent(ImagePart imagePart, Stream partStream)
{
imagePart.FeedData(partStream);
partStream.Close();
}
then if I add this lines :
Paragraph paragraph = sdtToSave.SdtContentBlock.GetFirstChild<Paragraph>();
Run run = new Run();
paragraph.Append(run);
run.Append(this.GenerateDrawing(mainPart.GetIdOfPart(newPart)));

all images are shown at the end of body.
From the OXML SDK productivity tool I can see that bookmarks are used to insert images inside a paragraph.
To summarize, I want to know how to keep images when moving content controls from header to the body.
Regards.
When you add your image part to the mainPart, it will be given a relId which is unlikely to be the same as the relId it had in the headerPart. So you'll have to adjust the relId in the drawing (Embed = relationshipID) to match.

Scaling multiple axes in PlotChart

When I programmatically create a PlotChart starting w/ no series and adding series w/ own scaling and verticalAxes (and Renderers but not necessary for behavior error), the axes and data show, but the default axis controls all scaling and the other axes are erroneous. Thus, the yValue magnitudes do not correspond to their associated axes and mixing series w/ grossly different orders of magnitude squishes all but the largest into indistinguishable floor values. I cannot null out the default vertical axis as it gets an null pointer error. [Click anywhere on the chart to add the next series.]
package
{
/*
* Attempt to dynamically create graph w/ varying series. Having difficulty getting axis to render correctly based
* on sets of series. Having trouble getting more than one series. I can't munge the yValue property because in my
* actual code all of the data elements are instances of the same class with properties akin to series, xValue, and yValue.

if(fieldName == 'yValue')
return(item.value);
else if(fieldName == "xValue")
return(item.date);

}
}
The problem was the line
series.setAxis("verticalAxis", seriesAxis);
That is not equivalent to
series.verticalAxis = seriesAxis;
Once I changed that, everything works perfectly, but it cannot handle the abstract Series class b/c that class does not have the setter for verticalAxis.
