I imported the DWG file into the eyeshot model. For reading file I used ReadAutodesk class. I want to apply Scaleup and Scaledown on the imported DWG file. I don’t understand how to do that. Can you please help me.
This is code I used.
private void RibbonRadioButton_Click(object sender, RoutedEventArgs e) {
OpenFileDialog openFileDialog1 = new OpenFileDialog() {
Filter = "DWG File|*.dwg|pdf file|*.pdf",
Multiselect = false,
AddExtension = true,
CheckFileExists = true,
CheckPathExists = true
};
string fileName = null;
if (fileName != null || openFileDialog1.ShowDialog().Value) {
System.Windows.Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new Action(delegate { }));
var rfa = new ReadAutodesk(fileName != null ? fileName : openFileDialog1.FileName);
ScaleTransform aa = new ScaleTransform(2,2.5,1,1);
rfa.DoWork();
rfa.AddToScene(model1);
Entity[] toAdd = model1.Entities.Explode();
model1.RenderTransform = aa;
model1.ZoomFit();
model1.Entities.AddRange(toAdd, NOT_MODIFIED_COLOR);
model1.SetView(viewType.Top);
// Fits the model in the viewport
model1.Invalidate();
}
}

Is there a published solution on Geotools userguide task?
In the link:
https://docs.geotools.org/stable/userguide/tutorial/map/style.html
there is a "Things to try":
In the Geometry and CRS tutorial we saw how to change the Coordinate Reference System of a MapContent. Try the following:
Modify this application so that you can change the CRS in which the
features are displayed.
Display the bc_voting_areas shapefile and change the CRS to
EPSG:4326
Now try to use the selection tool. You will find that it no longer
works !
I would like to find objects from different layers, who has different CRS, regardless of the map-window's CRS
This is my code that misses features in some layers (I can't understund why):
void selectFeatures(MapMouseEvent ev) {
Point screenPos = ev.getPoint();
Rectangle screenRect = new Rectangle(screenPos.x - 2, screenPos.y - 2, 5, 5);
AffineTransform screenToWorld = mapFrame.getMapPane().getScreenToWorldTransform();
Rectangle2D worldRect = screenToWorld.createTransformedShape(screenRect).getBounds2D();
ReferencedEnvelope bbox = new ReferencedEnvelope(worldRect,mapFrame.getMapContent().getCoordinateReferenceSystem());
try {
Iterator<Layer> it = map.layers().iterator();
IDs = new HashSet<>();
while (it.hasNext()) {
Layer l = it.next();
if (l.isSelected()) {
selectedFeatures = grabFeaturesInBoundingBox(bbox, l.getFeatureSource());
SimpleFeatureIterator iter = selectedFeatures.features();
while (iter.hasNext()) {
SimpleFeature feature = iter.next();
IDs.add(feature.getIdentifier());
System.out.println(" " + feature.getIdentifier());
}
iter.close();
}
}
if (IDs.isEmpty()) {
System.out.println(" no feature selected");
} else {
doSometing...
}
} catch (Exception ex) {
ex.printStackTrace();
}}
SimpleFeatureCollection grabFeaturesInBoundingBox(ReferencedEnvelope click, FeatureSource<?, ?> fs) throws Exception {
FilterFactory2 ff = CommonFactoryFinder.getFilterFactory2();
SimpleFeatureCollection sfc = null;
FeatureType schema = fs.getSchema();
String geometryPropertyName = schema.getGeometryDescriptor().getLocalName();
CoordinateReferenceSystem targetCRS = schema.getGeometryDescriptor().getCoordinateReferenceSystem();
ReferencedEnvelope bbox = click.transform(targetCRS, true);
Filter filter = ff.bbox(ff.property(geometryPropertyName), bbox);
sfc = featureSource.getFeatures(filter);
return sfc;}
Using OSMSharp I am having trouble to open a stream for a file (which I can provide on demand)
The error occurs in PBFReader (line 104)
using (var tmp = new LimitedStream(_stream, length))
{
header = _runtimeTypeModel.Deserialize(tmp, null, _blockHeaderType) as BlobHeader;
}
and states: "ProtoBuf.ProtoException: 'Invalid field in source data: 0'" which might mean different things as I have read in this SO question.
The file opens and is visualized with QGis so is not corrupt in my opinion.
Can it be that the contracts do not match? Is OsmSharp/core updated to the latest .proto files for OSM from here (although not sure if this is the real original source for the definition files).
And what might make more sense, can it be that the file I attached is generated for v2 of OSM PBF specification?
In the code at the line of the exception I see the following comment which makes me wonder:
// TODO: remove some of the v1 specific code.
// TODO: this means also to use the built-in capped streams.
// code borrowed from: http://stackoverflow.com/questions/4663298/protobuf-net-deserialize-open-street-maps
// I'm just being lazy and re-using something "close enough" here
// note that v2 has a big-endian option, but Fixed32 assumes little-endian - we
// actually need the other way around (network byte order):
// length = IntLittleEndianToBigEndian((uint)length);
BlobHeader header;
// again, v2 has capped-streams built in, but I'm deliberately
// limiting myself to v1 features
So this makes me wonder if OSM Sharp is (still) up-to-date.

Already I posted this question on the GITHube page of OSMSharp as is linked here. Any help would be very appreciated.
I need to update the Styles (styles.xml) part of an MS Word document due to a problem with a vendor's product.
So far I've been able to extract and update the xml I need. The only problem, is that I don't know how to save my changes back to the document.
The code below is working just fine. I usually output the xml to the console to make sure it's going in just fine. At the end, I know I need to perform some save operation, but the XDocument.Save( /stream/) hasn't worked.
Here's where I am so far
static void FixNormal()
{
using (WordprocessingDocument doc = WordprocessingDocument.Open(_path, true))
{
// Get the Styles part for this document.
StyleDefinitionsPart stylesPart = doc.MainDocumentPart.StyleDefinitionsPart;
// If the Styles part does not exist, add it and then add the style.
if (stylesPart == null)
{
Console.WriteLine("No Style Part");
}
else
{
XDocument stylesDoc;
using (var reader = XmlNodeReader.Create(stylesPart.GetStream(FileMode.Open, FileAccess.Read)))
{
XNamespace w = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
Console.WriteLine(stylesPart.Styles.OuterXml);
// Create the XDocument.
stylesDoc = XDocument.Load(reader);
var xStyle = stylesDoc.Descendants(w + "styles").Descendants(w + "style").Where(x => x.Attribute(w + "styleId").Value.Equals("Normal"));
XElement style = xStyle.Single();
var q = style.Descendants(w + "qFormat").FirstOrDefault();
if (q is null)
{
XElement qFormat = new XElement(w + "qFormat");
style.Add(qFormat);
}
var r = style.Descendants(w + "rsid").FirstOrDefault();
if (r is null)
{
XElement rsid = new XElement(w + "rsid");
XAttribute val = new XAttribute(w + "val", "003C4F1E");
rsid.Add(val);
style.Add(rsid);
}
}
//doc.Save(); --- Did not work
}
}
}
I found the answer in the SAVE THE PARTS section of this page Replace the styles parts in a word processing document (Open XML SDK)
See the end of this code for the solution. You'll also see what I've tried.
static void FixNormal()
{
using (WordprocessingDocument doc = WordprocessingDocument.Open(_path, true))
{
// Get the Styles part for this document.
StyleDefinitionsPart stylesPart = doc.MainDocumentPart.StyleDefinitionsPart;
// If the Styles part does not exist, add it and then add the style.
if (stylesPart == null)
{
Console.WriteLine("No Style Part");
}
else
{
XDocument stylesDoc;
using (var reader = XmlNodeReader.Create(stylesPart.GetStream(FileMode.Open, FileAccess.Read)))
{
XNamespace w = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
// Create the XDocument.
stylesDoc = XDocument.Load(reader);
var xStyle = stylesDoc.Descendants(w + "styles").Descendants(w + "style").Where(x => x.Attribute(w + "styleId").Value.Equals("Normal"));
XElement style = xStyle.Single();
var q = style.Descendants(w + "qFormat").FirstOrDefault();
if (q is null)
{
XElement qFormat = new XElement(w + "qFormat");
style.Add(qFormat);
}
var r = style.Descendants(w + "rsid").FirstOrDefault();
if (r is null)
{
XElement rsid = new XElement(w + "rsid");
XAttribute val = new XAttribute(w + "val", "003C4F1E");
rsid.Add(val);
style.Add(rsid);
}
}
//doc.Save(); --- Did not work
//stylesDoc.Save(#"C:\WinTest\HooRah.xml"); -- I only use this to verify that I've updated everything correctly
//using (XmlWriter xw = XmlWriter.Create(stylesPart.GetStream(FileMode.Create, FileAccess.Write)))
//{
// stylesDoc.Save(xw); -- DID NOT WORK EITHER
// doc.Save();
//}
// THIS WORKED
stylesDoc.Save(new StreamWriter(stylesPart.GetStream(FileMode.Create, FileAccess.Write)));
}
}
}
Background
Our Eclipse RCP 3.6-based application lets people drag files in for storage/processing. This works fine when the files are dragged from a filesystem, but not when people drag items (messages or attachments) directly from Outlook.
This appears to be because Outlook wants to feed our application the files via a FileGroupDescriptorW and FileContents, but SWT only includes a FileTransfer type. (In a FileTransfer, only the file paths are passed, with the assumption that the receiver can locate and read them. The FileGroupDescriptorW/FileContents approach can supply files directly application-to-application without writing temporary files out to disk.)
We have tried to produce a ByteArrayTransfer subclass that could accept FileGroupDescriptorW and FileContents. Based on some examples on the Web, we were able to receive and parse the FileGroupDescriptorW, which (as the name implies) describes the files available for transfer. (See code sketch below.) But we have been unable to accept the FileContents.
This seems to be because Outlook offers the FileContents data only as TYMED_ISTREAM or TYMED_ISTORAGE, but SWT only understands how to exchange data as TYMED_HGLOBAL. Of those, it appears that TYMED_ISTORAGE would be preferable, since it's not clear how TYMED_ISTREAM could provide access to multiple files' contents.
(We also have some concerns about SWT's desire to pick and convert only a single TransferData type, given that we need to process two, but we think we could probably hack around that in Java somehow: it seems that all the TransferDatas are available at other points of the process.)
Questions
Are we on the right track here? Has anyone managed to accept FileContents in SWT yet? Is there any chance that we could process the TYMED_ISTORAGE data without leaving Java (even if by creating a fragment-based patch to, or a derived version of, SWT), or would we have to build some new native support code too?
Relevant code snippets
Sketch code that extracts file names:
// THIS IS NOT PRODUCTION-QUALITY CODE - FOR ILLUSTRATION ONLY
final Transfer transfer = new ByteArrayTransfer() {
private final String[] typeNames = new String[] { "FileGroupDescriptorW", "FileContents" };
private final int[] typeIds = new int[] { registerType(typeNames[0]), registerType(typeNames[1]) };
#Override
protected String[] getTypeNames() {
return typeNames;
}
#Override
protected int[] getTypeIds() {
return typeIds;
}
#Override
protected Object nativeToJava(TransferData transferData) {
if (!isSupportedType(transferData))
return null;
final byte[] buffer = (byte[]) super.nativeToJava(transferData);
if (buffer == null)
return null;
try {
final DataInputStream in = new DataInputStream(new ByteArrayInputStream(buffer));
long count = 0;
for (int i = 0; i < 4; i++) {
count += in.readUnsignedByte() << i;
}
for (int i = 0; i < count; i++) {
final byte[] filenameBytes = new byte[260 * 2];
in.skipBytes(72); // probable architecture assumption(s) - may be wrong outside standard 32-bit Win XP
in.read(filenameBytes);
final String fileNameIncludingTrailingNulls = new String(filenameBytes, "UTF-16LE");
int stringLength = fileNameIncludingTrailingNulls.indexOf('\0');
if (stringLength == -1)
stringLength = 260;
final String fileName = fileNameIncludingTrailingNulls.substring(0, stringLength);
System.out.println("File " + i + ": " + fileName);
}
in.close();
return buffer;
}
catch (final Exception e) {
return null;
}
}
};
In the debugger, we see that ByteArrayTransfer's isSupportedType() ultimately returns false for the FileContents because the following test is not passed (since its tymed is TYMED_ISTREAM | TYMED_ISTORAGE):
if (format.cfFormat == types[i] &&
(format.dwAspect & COM.DVASPECT_CONTENT) == COM.DVASPECT_CONTENT &&
(format.tymed & COM.TYMED_HGLOBAL) == COM.TYMED_HGLOBAL )
return true;
This excerpt from org.eclipse.swt.internal.ole.win32.COM leaves us feeling less hope for an easy solution:
public static final int TYMED_HGLOBAL = 1;
//public static final int TYMED_ISTORAGE = 8;
//public static final int TYMED_ISTREAM = 4;
Thanks.
even if
//public static final int TYMED_ISTREAM = 4;

Have you looked at https://bugs.eclipse.org/bugs/show_bug.cgi?id=132514 ?
Attached to this bugzilla entry is an patch (against an rather old version of SWT) that might be of interest.
I had the same problem and created a small library providing a Drag'n Drop Transfer Class for JAVA SWT. It can be found here:
https://github.com/HendrikHoetker/OutlookItemTransfer
Currently it supports dropping Mail Items from Outlook to your Java SWT application and will provide a list of OutlookItems with the Filename and a byte array of the file contents.
All is pure Java and in-memory (no temp files).
Usage in your SWT java application:
if (OutlookItemTransfer.getInstance().isSupportedType(event.currentDataType)) {
Object o = OutlookItemTransfer.getInstance().nativeToJava(event.currentDataType);
if (o != null && o instanceof OutlookMessage[]) {
OutlookMessage[] outlookMessages = (OutlookMessage[])o;
for (OutlookMessage msg: outlookMessages) {
//...
}
}
}
The OutlookItem will then provide two elements: filename as String and file contents as array of byte.
From here on, one could write it to a file or further process the byte array.
To your question above:
- What you find in the file descriptor is the filename of the outlook item and a pointer to an IDataObject
- the IDataObject can be parsed and will provide an IStorage object
- The IStorageObject will be then a root container providing further sub-IStorageObjects or IStreams similar to a filesystem (directory = IStorage, file = IStream
You find those elements in the following lines of code:
Get File Contents, see OutlookItemTransfer.java, method nativeToJava:
FORMATETC format = new FORMATETC();
format.cfFormat = getTypeIds()[1];
format.dwAspect = COM.DVASPECT_CONTENT;
format.lindex = <fileIndex>;
format.ptd = 0;
format.tymed = TYMED_ISTORAGE | TYMED_ISTREAM | COM.TYMED_HGLOBAL;
STGMEDIUM medium = new STGMEDIUM();
if (data.GetData(format, medium) == COM.S_OK) {
// medium.tymed will now contain TYMED_ISTORAGE
// in medium.unionfield you will find the root IStorage
}
Read the root IStorage, see CompoundStorage, method readOutlookStorage:
// open IStorage object
IStorage storage = new IStorage(pIStorage);
storage.AddRef();
// walk through the content of the IStorage object
long[] pEnumStorage = new long[1];
if (storage.EnumElements(0, 0, 0, pEnumStorage) == COM.S_OK) {
// get storage iterator
IEnumSTATSTG enumStorage = new IEnumSTATSTG(pEnumStorage[0]);
enumStorage.AddRef();
enumStorage.Reset();
// prepare statstg structure which tells about the object found by the iterator
long pSTATSTG = OS.GlobalAlloc(OS.GMEM_FIXED | OS.GMEM_ZEROINIT, STATSTG.sizeof);
int[] fetched = new int[1];
while (enumStorage.Next(1, pSTATSTG, fetched) == COM.S_OK && fetched[0] == 1) {
// get the description of the the object found
STATSTG statstg = new STATSTG();
COM.MoveMemory(statstg, pSTATSTG, STATSTG.sizeof);
// get the name of the object found
String name = readPWCSName(statstg);
// depending on type of object
switch (statstg.type) {
case COM.STGTY_STREAM: { // load an IStream (=File)
long[] pIStream = new long[1];
// get the pointer to the IStream
if (storage.OpenStream(name, 0, COM.STGM_DIRECT | COM.STGM_READ | COM.STGM_SHARE_EXCLUSIVE, 0, pIStream) == COM.S_OK) {
// load the IStream
}
}
case COM.STGTY_STORAGE: { // load an IStorage (=SubDirectory) - requires recursion to traverse the sub dies
}
}
}
}
// close the iterator
enumStorage.Release();
}
// close the IStorage object
storage.Release();

finally

}
IFullTextSession fullTextSession = Search.CreateFullTextSession(this.Session);

still uses obsolete code. Could anyone be so kind and point out the necessary change. Thanks.

PS
Try using FSDirectory.Open(path) instead.
