i have a javaFx application and am working on the Printer module , in the software am done with other things, like installed printer list , taking print from the specific printer but getting issue in the layout , now am having 80mm printer and when i get print from this printer then there are lots of margin in left side and right side, please help me to get correct print.
am using following code for print:-
PageLayout pageLayout = prnterForJob.createPageLayout(Paper.MONARCH_ENVELOPE,
PageOrientation.PORTRAIT, 0, 0, 0, 0);
PrinterJob job = PrinterJob.createPrinterJob(prnterForJob);
job.getJobSettings().setCopies(nmbrOfCopies1);
if (job != null) {
//boolean success = job.printPage(node);
weOrderPrint.print(job);
job.endJob();
}
Aren't you just forgetting to set the page layout you created?
job.getJobSettings().setPageLayout(pageLayout);

I'm trying to drop a shadow on a borderless window using Qt in windows.
I succeeded in dropping the shadow when launching the application, referring to the following article.
Borderless Window Using Areo Snap, Shadow, Minimize Animation, and Shake
Borderless Window with Drop Shadow
But I encountered the problem that the shadow will disappear if the application is deactivated and reactivated (
In other words, click the other applications, and click my application again.)
Perhaps my implementation is not good enough.
I'm glad if you have some ideas for this issue.
I'm trying to imprement Qt with Go bindings
Here is the code snippet:
package qframelesswindow
import (
"unsafe"
"github.com/therecipe/qt/core"
"github.com/therecipe/qt/widgets"
win "github.com/akiyosi/w32"
)
func (f *QFramelessWindow) SetNativeEvent(app *widgets.QApplication) {
filterObj := core.NewQAbstractNativeEventFilter()
filterObj.ConnectNativeEventFilter(func(eventType *core.QByteArray, message unsafe.Pointer, result int) bool {
msg := (*win.MSG)(message)
lparam := msg.LParam
hwnd := msg.Hwnd
var uflag uint
uflag = win.SWP_NOZORDER | win.SWP_NOOWNERZORDER | win.SWP_NOMOVE | win.SWP_NOSIZE | win.SWP_FRAMECHANGED
var nullptr win.HWND
shadow := &win.MARGINS{0, 0, 0, 1}
switch msg.Message {
case win.WM_CREATE:
style := win.WS_POPUP | win.WS_THICKFRAME | win.WS_MINIMIZEBOX | win.WS_MAXIMIZEBOX | win.WS_CAPTION
win.SetWindowLong(hwnd, win.GWL_STYLE, uint32(style))
win.DwmExtendFrameIntoClientArea(hwnd, shadow)
win.SetWindowPos(hwnd, nullptr, 0, 0, 0, 0, uflag)
return true
case win.WM_NCCALCSIZE:
if msg.WParam == 1 {
// this kills the window frame and title bar we added with WS_THICKFRAME and WS_CAPTION
result = 0
return true
}
return false
case win.WM_GETMINMAXINFO:
mm := (*win.MINMAXINFO)((unsafe.Pointer)(lparam))
mm.PtMinTrackSize.X = int32(f.minimumWidth)
mm.PtMinTrackSize.Y = int32(f.minimumHeight)
return true
default:
}
return false
})
app.InstallNativeEventFilter(filterObj)
}
All source code is in my repository;

WM_NCCALCSIZE:
If wParam is TRUE, the application should return zero or a combination
of the following values.(In document)
And also:
When wParam is TRUE, simply returning 0 without processing the
NCCALCSIZE_PARAMS rectangles will cause the client area to resize to
the size of the window, including the window frame. This will remove
the window frame and caption items from your window, leaving only the
client area displayed.
Starting with Windows Vista, simply returning 0 does not affect extended frames, only the standard frame will be removed.
EDIT:
Set the return value with the DWL_MSGRESULT instead of result = 0.
I have a working app that draws NSAttributedStrings into a custom view. The NSAttributedStrings can included embedded images. This works on versions of macOS prior to Mojave. The app can display the strings on screen, print them, and save them to image files.
This is apparently broken under Mojave. Weirdly, printing and saving to image files still works; but on-screen, the strings display only the text and not the embedded images. Proper space is left for the images, but that space is blank.
I've tested by building a small app that shows a window with an NSTextField (a label) and a custom view. It makes a single NSAttributedString with an embedded image. It applies that string to the attributedStringValue of the label, and also calls drawInRect: on the same string in the drawRect: method of the custom view. In the label, the string is displayed correctly, image and all. But in the custom view, only the text appears, and the space where the image should be is blank.
Anybody got a clue why this is happening on Mojave but not on earlier versions of macOS?
Here is the code that makes the string (and caches it, for re-use):
static NSMutableAttributedString* sgAttrString = nil;
/*
* Creates an attributed string the first time it's called,
* then returns that same string each time it's called.
*/
+ (NSAttributedString*)getAttributedString
{
if (sgAttrString == nil)
{
NSFont* font = [NSFont fontWithName:#"Helvetica" size:24.0];
NSDictionary *attrs = #{
NSFontAttributeName: font
};
sgAttrString = [[NSMutableAttributedString alloc] initWithString:#"Daisy: " attributes:attrs];
NSImage* daisy = [NSImage imageNamed:#"daisy.png"];
[daisy setSize:NSMakeSize(24,24)];
NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
// I'm aware that attachment.image is available only on macOS 10.11 and later.
// It's not an issue in my real project.
attachment.image = daisy;
NSMutableAttributedString* imageStr = [[NSMutableAttributedString alloc] init];
[imageStr setAttributedString:[NSAttributedString attributedStringWithAttachment:attachment]];
[sgAttrString appendAttributedString:imageStr];
[sgAttrString appendAttributedString: [[NSAttributedString alloc] initWithString:#" !!" attributes:attrs]];
}
return sgAttrString;
}
Here is the code that applies the string to the NSTextField:
NSAttributedString* str = [Utilities getAttributedString];
self.label.attributedStringValue = str;
And here is the code that draws the string in a custom NSView:
NSAttributedString* str = [Utilities getAttributedString];
[str drawInRect:NSMakeRect(50,50, 300, 40)];
Again, this behavior seems to occur only in Mojave! Thanks in advance for any help.
I'm displaying a ControlsFX PopOver for invoice, naturally its content must be printable. I have successfully print it using this code:
val printer = Printer.getDefaultPrinter()
val layout = printer.createPageLayout(PAPER_INVOICE, PORTRAIT, 0.0, 0.0, 0.0, 0.0)
printer.printerAttributes
val job = PrinterJob.createPrinterJob()
invoiceBox.run {
border = null
transforms += Scale(
layout.printableWidth / invoiceBox.boundsInParent.width,
layout.printableHeight / invoiceBox.boundsInParent.height
)
}
if (job != null && job.showPrintDialog(invoiceBox.scene.window)) {
val success = job.printPage(layout, invoiceBox)
if (success) {
job.endJob()
}
}
However, the whole application becomes unusable after the printing process (even after canceling the print dialog). The main window is still there, it just can't be focused while clicking on it (or the app in the Windows taskbar) just produces error sound. Is this a known bug?
I have only tested this on Windows since I don't believe the printer I'm working with (Epson LX-310) are compatible with Mac/Linux.
Bit of a strange question and I don't know whether anyone will have come across this one before.
We have a ASP.net page generating physical thumbnail jpeg files on a filesystem and copying fullsize images to a different location. So we input one image and we get a complete copy in one location and a small image 102*68 in a different location.
We're currently looking to finally move away from IIS6 on Server 2003 to IIS7.5 on Server 2008R2, except there's on problem.
On the old system (so IIS6/Server 2003) the black borders are removed and the image stays at the correct ration. On the new system (IIS7.5/Server 2008) the thumbnails are rendered exactly as they exist in the JPEG, with black borders, but this makes the thumbnail slightly squashed and obviously includes ugly black borders.
Anyone know why this might be happening? I've done a google and can't seem to find out which behaviour is "correct". My gut tells me that the new system is correctly rendering the thumbnail as it exists, but I don't know.
Anyone have any suggestions how to solve the problem?
I think as suggested it is the .net differences. not IIS.
Just re write your code, your save a lot of time, very simple thing to do.
Here is a image handler i wrote a while ago that re draws any image to your settings.
public class image_handler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
// set file
string ImageToDraw = context.Request.QueryString["FilePath"];
ImageToDraw = context.Server.MapPath(ImageToDraw);
// Grab images to work on's true width and height
Image ImageFromFile = Image.FromFile(ImageToDraw);
double ImageFromFileWidth = ImageFromFile.Width;
double ImageFromFileHeight = ImageFromFile.Height;
ImageFromFile.Dispose();
// Get required width and work out new dimensions
double NewHeightRequired = 230;
if (context.Request.QueryString["imageHeight"] != null)
NewHeightRequired = Convert.ToDouble(context.Request.QueryString["imageHeight"]);
double DivTotal = (ImageFromFileHeight / NewHeightRequired);
double NewWidthValue = (ImageFromFileWidth / DivTotal);
double NewHeightVale = (ImageFromFileHeight / DivTotal);
NewWidthValue = ImageFromFileWidth / (ImageFromFileWidth / NewWidthValue);
NewHeightVale = ImageFromFileHeight / (ImageFromFileHeight / NewHeightVale);
// Set new width, height
int x = Convert.ToInt16(NewWidthValue);
int y = Convert.ToInt16(NewHeightVale);
Bitmap image = new Bitmap(x, y);
Graphics g = Graphics.FromImage(image);
Image thumbnail = Image.FromFile(ImageToDraw);
// Quality Control
g.InterpolationMode = InterpolationMode.HighQualityBicubic;
g.SmoothingMode = SmoothingMode.HighQuality;
g.PixelOffsetMode = PixelOffsetMode.HighQuality;
g.CompositingQuality = CompositingQuality.HighQuality;
g.DrawImage(thumbnail, 0, 0, x, y);
g.Dispose();
image.Save(context.Response.OutputStream, ImageFormat.Jpeg);
image.Dispose();
}

get
{
return true;
}

I've ran into a weird problem with getCharBoundaries, I could not figure out what coordinate space the coordinates returned from the function was in. What ever I tried I could not get it to match up with what I expected.
So I made a new project and and added simple code to highlight the last charater in a textfield, and all of a sudden it worked fine. I then tried to copy over the TextField that had been causing me problems, into the new project. And now the same weird offset appeared 50px on the x axis. Everything else was spot on.
So after some headscracthing comparing the two TextFields, I simply can not see a difference in their properties or transformation.
So I was hoping that someone might now what property might affect the coordinates returned by getCharBoundaries.
I am using Flash CS4.
I've just had exactly the same problem and thought I'd help out by offering what my findings are. With a help from this thread, I tried to find everything that wasn't 'default' about the textfield I was using. I found that when I had switched my TextFormatAlign (or 'align' in the IDE) and TextFieldAutoSize properties to 'LEFT' as opposed to 'CENTER', it solved the problem.
A little late in the game perhaps, but worth knowing for anyone running into the same problem. This was the only thread I could find that raised the right flag...
Well the getCharBoundaries returns the boundaries in the textfield coordinate system. Where the origin is topleft corner of the textfield.
getCharBoundaries does not take into consideration the scrolling. you need to check if there are scrollbars on its parent (textarea) and if so relocate. One quick way of doing it is using localtoglobal and globaltolocal. Use the first to translate from the textfield coordinate system to the application coordinate system and then use the second to translate from the app coordinate system to the coordinate system of the parent of the textfield which is the textarea. I'm fine tuning a my method to get char boundaries i will publish it today on my blog

Works For Me(tm) (Flex Builder AS3 project):
[Embed(systemFont="Segoe UI", fontWeight="bold", fontName="emb",
mimeType="application/x-font")]
private var EmbeddedFont:Class;
public function ScratchAs3()
{
stage.scaleMode = 'noScale';
stage.align = 'tl';
var m:Matrix = new Matrix(.8, .1, -.1, 1.1, 26, 78);
var t:TextField = new TextField();
t.autoSize = 'left';
t.wordWrap = false;
t.embedFonts = true;
t.defaultTextFormat = new TextFormat("emb", 100, 0, true);
t.transform.matrix = m;
t.text = "TEST STRING.";
addChild(t);
var r:Rectangle = t.getCharBoundaries(8);
var tl:Point = m.transformPoint(r.topLeft);
var tr:Point = m.transformPoint(new Point(r.right, r.top));
var bl:Point = m.transformPoint(new Point(r.left, r.bottom));
var br:Point = m.transformPoint(r.bottomRight);
graphics.beginFill(0xFF, .6);
graphics.moveTo(tl.x, tl.y);
graphics.lineTo(tr.x, tr.y);
graphics.lineTo(br.x, br.y);
graphics.lineTo(bl.x, bl.y);
graphics.lineTo(tl.x, tl.y);
}
To literally answer your question, it returns the coordinates in the TextField's coordinate system, not it's parent, and it is affected by DisplayObject.transform.matrix, which is the backing for the .x, .y, .scaleX, .scaleY, .width, .height, and .rotation properties.
What ever it was the solution was simple to add a new TextField, never found out what property screwed everything up.
The first answer is correct in most cases. However if your field is parented to another movie clip it may still return the wrong y coordinate. try this code:
//if this doesn't work:
myTextFormat = new TextFormat();
myTextFormat.align = TextFormatAlign.LEFT;
myFieldsParent.myField.autoSize = TextFieldAutoSize.LEFT;
myFieldsParent.myField.setTextFormat( myTextFormat);
//try this:
var x = myFieldsParent.myField.getCharBoundaries(o).x;
var y = myFieldsParent.myField.getCharBoundaries(o).y;
var myPoint:Point = new Point(myField.getCharBoundaries(o).x,myField.getCharBoundaries(o).y);
var pt:Point = new Point(myFieldsParent.myField.getCharBoundaries(o).x, myFieldsParent.myField.getCharBoundaries(o).y);
pt = myFieldsParent.myField.localToGlobal(pt);
//pt is the variable containing the coordinates of the char in the stage's coordinate space. You may still need to offset it with a fixed value but it should be constant.
I didn't test this code as I have adapted this example from code that is embedded into my project so I apologize if I'm missing something...
