I'm attempting to create a feature layer in ARC GIS using a shape file but I'm getting the following exception when trying to open the shape file with ShapefileFeatureTable.OpenAsync
{"Geodatabase field exists: fid"}
var shapeFileFeatureTable = ShapefileFeatureTable.OpenAsync(#"...\myshape.shp").Result;
fl = new FeatureLayer(shapeFileFeatureTable)
{
// Set the rendering mode of the feature layer to be dynamic (needed for extrusion to work).
RenderingMode = FeatureRenderingMode.Dynamic,
IsVisible = true,
};

I was wondering if there was a way to ensure that a data matrix code created with ZXing.Net comes out as a square?
I'm not talking about the the image itself but the code itself.
I have code that generates images with data matrix codes from input texts and in some cases it is a square code (the code not the image) and in other cases it is more like a flat rectangle (the code, not the image).
So is the flat rectangular code just how the code looks due to the input or can it in fact be forced into a square?
You can try the following snippet:
var writer = new BarcodeWriter
{
Format = BarcodeFormat.DATA_MATRIX,
Options = new DatamatrixEncodingOptions
{
SymbolShape = SymbolShapeHint.FORCE_SQUARE
}
};
var image = writer.Write("<your content here>");
I just registered. I try to address the following case:
Given a basic pdf (a simple, single raster image), I want to get to:
Create a pdf (empty initially), in which I create a layer, in which I embed the raster image of the input_pdf, and mark said layer as visible and not_printable.
Are there tools to do it?
Thanks for the tips.
Since you do not specify a language or a library you use, here it is a solution in C#:
// Extract the page content from the source file.
FileStream stream = File.OpenRead("input.pdf");
PDFFile source = new PDFFile(stream);
PDFPageContent pageContent = source.ExtractPageContent(0);
stream.Close();
PDFFixedDocument document = new PDFFixedDocument();
document.OptionalContentProperties = new PDFOptionalContentProperties();
PDFPage page = document.Pages.Add();
// Create an optional content group (layer) for the extracted page content.
PDFOptionalContentGroup ocg = new PDFOptionalContentGroup();
ocg.Name = "Embedded page";
ocg.VisibilityState = PDFOptionalContentGroupVisibilityState.AlwaysVisible;
ocg.PrintState = PDFOptionalContentGroupPrintState.NeverPrint;
// Draw the extracted page content in the layer
page.Canvas.BeginOptionalContentGroup(ocg);
page.Canvas.DrawFormXObject(pageContent, 0, 0, page.Width, page.Height);
page.Canvas.EndOptionalContentGroup();
// Build the display tree for the optional content
PDFOptionalContentDisplayTreeNode ocgNode = new PDFOptionalContentDisplayTreeNode(ocg);
document.OptionalContentProperties.DisplayTree.Nodes.Add(ocgNode);
using (FileStream output = File.Create("EmbedPageAsLayer.pdf"))
{
document.Save(output);
}
The output PDF file is available here: https://github.com/o2solutions/pdf4net/blob/master/GettingStarted/EmbedPageAsLayer/EmbedPageAsLayer.pdf
How can I grab an image by its location on my local machine and insert it into a layer with extendscript?
var doc = app.documents.add();
var layer = doc.artLayers.add();
var img = new File('~/Desktop/tanks.png');
layer.image = img; //I want to add the image to this layer
All I can seem to do is open the image as a background which creates a new photoshop doc in the process;
var opened = open(img);
But what I would like to achieve is to open multiple images into the same doc as multiple layers. Can this be done?
Open each of the images you want to consolidate using the open method you found. Then cycle through the open document and use the duplicate method on the art layer object to copy all the layers to a single target document. See the code snippet below for copying a single layer image to a new doc.
//copy the layer into the target document
app.activeDocument = pSourceDocument;
pSourceDocument.artLayers[0].duplicate(pTargetDocument);
I found a very useful script for doing this here https://forums.adobe.com/message/3946944#3946944
I took the piece of this script and it worked for me. First of all, you need to convert the layer which contents you want to replace with the image to a Smart Object (in other case contents of the layer can't be replaced by scripts). To do so, open the file you want to modificate in Photoshop, select the layer, click Layer > Smart Objects > Group into New Smart Object. Now this layer is a Smart Object.
Then create a script with the following code:
var replacementFile = new File("X:/file.jpg");
var theLayer = app.documents[0].artLayers.getByName("targetLayer");
theLayer = replaceContents(replacementFile);
////// replace contents //////
function replaceContents (newFile) {
// =======================================================
var idplacedLayerReplaceContents = stringIDToTypeID( "placedLayerReplaceContents" );
var desc3 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
desc3.putPath( idnull, new File( newFile ) );
var idPgNm = charIDToTypeID( "PgNm" );
desc3.putInteger( idPgNm, 1 );
executeAction( idplacedLayerReplaceContents, desc3, DialogModes.NO );
return app.activeDocument.activeLayer
};
I am programmatically drawing a flowchart using Java UNO Runtime Reference in which I want to display grid Lines permanently.Using following code I was able to display the Grid Lines but they are toggled ON and OFF alternately when the code executes.
XModel xModel = (XModel) UnoRuntime.queryInterface(XModel.class, xDrawDoc);
XController xController = xModel.getCurrentController();
XDispatchProvider xDisp = UnoRuntime.queryInterface(XDispatchProvider.class, xController);
XMultiComponentFactory xMCF = xContext.getServiceManager();
Object dispatchHelper = xMCF.createInstanceWithContext("com.sun.star.frame.DispatchHelper", xContext);
XDispatchHelper xDispatchHelper = UnoRuntime.queryInterface(XDispatchHelper.class, dispatchHelper);
PropertyValue[] navigatorDesc = new PropertyValue[1];
navigatorDesc[0] = new PropertyValue();
navigatorDesc[0].Name = "GridVisible";
navigatorDesc[0].Value = true;
xDispatchHelper.executeDispatch(xDisp, ".uno:GridVisible" , "", 0, navigatorDesc);
I want to permanently show Grid Lines.How can I achieve this using Java.Pls suggest. If there is any way of checking whether the Grid Lines are ON(any method which could return a boolean value), this could also be a useful approach.
I'm trying to create IconicTile using image saved on isolated storage.
At first, I saved image to isolated storage.
// bitmap is Stream of image source (e.g. from PhotoChooserTask)
var wbmp = new WriteableBitmap(bitmap);
var file = "Shared/ShellContent/IconicTile.png";
// when file exists, delete it
if (storage.FileExists(file))
{
storage.DeleteFile(file);
}
using (var isoFileStream = new IsolatedStorageFileStream(file, FileMode.Create, storage))
{
// use ToolStackPNGWriterExtensions
wbmp.WritePNG(isoFileStream);
}
And I have confirmed PNG file is successfully created using Isostorage Explorer Tools.
Then I try to create IconicTile.
var initialData = new IconicTileData
{
BackgroundColor = SelectedColor,
IconImage = new Uri("isostore:/Shared/ShellContent/IconicTile.png", UriKind.Absolute),
Title = tbTitle.Text,
WideContent1 = tbWideContent1.Text,
WideContent2 = tbWideContent2.Text,
WideContent3 = tbWideContent3.Text
};
var uri = string.Format("/SecondaryPage.xaml");
var TileToFind = ShellTile.ActiveTiles.FirstOrDefault(x => x.NavigationUri.ToString().Contains(uri));
if (TileToFind == null)
ShellTile.Create(new Uri(uri, UriKind.Relative), initialData, true);
else
TileToFind.Update(initialData);
But image in the created tile are white.
(I'd like to attach image but my reputation is too low. Sorry.)
I tried not only PNG format but also JPG format, but neither doesn't work.
Is there anyway to create IconicTile using image on IsolatedStorage?
The iconic tile format expects a transparent background, based on your comment at the first line (PhotoChooserTask), I suspect you're using some type of image with no transparency.
