I'm trying to create Pdf using itextsharp. I have added one table conataining two columns one containing text and other image. I want to have constant image size
My Image automatically resizes if the text present in another cell increases and image present in other cell has different sizes
for (int i = 0; i < visitInfo.VisitsiteComplience.Count; ++i)
{
cellprop.Colspan = 1;
cellprop.Pharse = visitInfo.VisitsiteComplience[i].Compliencedescription;
cellprop.BaseColor = null;
table.AddCell(AddCelltoTable(cellprop));
yesicon.ScaleAbsolute(35f, 35f);
noicon.ScaleAbsolute(35f, 35f);
if (visitInfo.VisitsiteComplience[i].Status == "1")
{
statuscell.AddElement(new Chunk(noicon, 0, 0));
}
else
{
// statuscell.AddElement(new Chunk(noicon, 0, 0));
}
statuscell.FixedHeight = 10;
//headerLeftCell.Border = PdfPCell.NO_BORDER;
table.AddCell(statuscell);
}
2. Then I changed the code but now Image size increases and occupies full cell
for (int i = 0; i < visitInfo.VisitsiteComplience.Count; ++i)
{
cellprop.Colspan = 1;
cellprop.Pharse = visitInfo.VisitsiteComplience[i].Compliencedescription;
cellprop.BaseColor = null;
table.AddCell(AddCelltoTable(cellprop));
yesicon.ScaleAbsolute(35f, 35f);
noicon.ScaleAbsolute(35f, 35f);
if (visitInfo.VisitsiteComplience[i].Status == "1")
{
statuscell.AddElement(new Chunk(noicon, 0, 0));
}
else
{
// statuscell.AddElement(new Chunk(noicon, 0, 0));
}
//headerLeftCell.Border = PdfPCell.NO_BORDER;
table.AddCell(statuscell);
}
I think you're scaling the image yourself like this: noicon.ScaleAbsolute(35f, 35f);
It also puzzles me why you're wrapping the image inside a Chunk. You can create a PdfPCell that takes an Image as parameter as well as a Bool to defines whether or not iText should scale the Image. See page 109 of the book iText in Action (of which I'm the author) and take a look at the XMen example of chapter 4.
Image image = Image.getInstance("D:/star.png");
PdfPCell cell = new PdfPCell();
cell.setFixedHeight(40f);
cell.addElement(image);
table.addCell(cell);

I am trying to get an image using the camera. The image is to be 256x256 and I want it to come from the centre of a photo taken using the camera on a phone. I found this code at: https://forums.xamarin.com/discussion/37647/cross-platform-crop-image-view
I am using this code for Android...

//options.InPurgeable = true; see http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html
using (var photoToCropBitmap = BitmapFactory.DecodeByteArray(photoToCropBytes, 0, photoToCropBytes.Length, options))

I am struggling to work out exactly what the parameters are to call the function.
Currently, I am doing the following:
double cropSize = Math.Min(DeviceDisplay.MainDisplayInfo.Width, DeviceDisplay.MainDisplayInfo.Height);
double left = (DeviceDisplay.MainDisplayInfo.Width - cropSize) / 2.0;
double top = (DeviceDisplay.MainDisplayInfo.Height - cropSize) / 2.0;
// Get a square resized and cropped from the top image as a byte[]
_imageData = mediaService.CropPhoto(_imageData, new Rectangle(left, top, cropSize, cropSize), 256, 256);
I was expecting this to crop the image to the central square (in portrait mode side length would be the width of the photo) and then scale it down to a 256x256 image. But it never picks the centre of the image.
Has anyone ever used this code and can tell me what I need to pass in for the 'rectangleToCrop' parameter?
Note: Both Android and iOS give the same image, just not the central part that I was expecting.
Here are the two routines I used:
Android:
public byte[] ResizeImageAndCropToSquare(byte[] rawPhoto, int outputSize)
{
// Create object of bitmapfactory's option method for further option use
BitmapFactory.Options options = new BitmapFactory.Options();
// InPurgeable is used to free up memory while required
options.InPurgeable = true;
// Get the original image
using (var originalImage = BitmapFactory.DecodeByteArray(rawPhoto, 0, rawPhoto.Length, options))
{
// The shortest edge will determine the size of the square image
int cropSize = Math.Min(originalImage.Width, originalImage.Height);
int left = (originalImage.Width - cropSize) / 2;
int top = (originalImage.Height - cropSize) / 2;
using (var squareImage = Bitmap.CreateBitmap(originalImage, left, top, cropSize, cropSize))
{
// Resize the square image to the correct size of an Avatar
using (var resizedImage = Bitmap.CreateScaledBitmap(squareImage, outputSize, outputSize, true))
{
// Return the raw data of the resized image
using (MemoryStream resizedImageStream = new MemoryStream())
{
// Resize the image maintaining 100% quality
resizedImage.Compress(Bitmap.CompressFormat.Png, 100, resizedImageStream);
return resizedImageStream.ToArray();
}
}
}
}
}
iOS:
private const int BitsPerComponent = 8;
public byte[] ResizeImageAndCropToSquare(byte[] rawPhoto, int outputSize)
{
using (var data = NSData.FromArray(rawPhoto))
{
using (var photoToCrop = UIImage.LoadFromData(data).CGImage)
{
nint photoWidth = photoToCrop.Width;
nint photoHeight = photoToCrop.Height;
nint cropSize = photoWidth < photoHeight ? photoWidth : photoHeight;
nint left = (photoWidth - cropSize) / 2;
nint top = (photoHeight - cropSize) / 2;
// Crop image
using (var photoCropped = photoToCrop.WithImageInRect(new CGRect(left, top, cropSize, cropSize)))
{
using (var photoCroppedUIImage = UIImage.FromImage(photoCropped))
{
// Create a 24bit RGB image of output size
using (var cGBitmapContext = new CGBitmapContext(IntPtr.Zero, outputSize, outputSize, BitsPerComponent, outputSize << 2, CGColorSpace.CreateDeviceRGB(), CGImageAlphaInfo.PremultipliedFirst))
{
var photoOutputRectangleF = new RectangleF(0f, 0f, outputSize, outputSize);
// Draw the cropped photo resized
cGBitmapContext.DrawImage(photoOutputRectangleF, photoCroppedUIImage.CGImage);
// Get cropped resized photo
var photoOutputUIImage = UIImage.FromImage(cGBitmapContext.ToImage());
// Convert cropped resized photo to bytes and then stream
using (var photoOutputNsData = photoOutputUIImage.AsPNG())
{
var rawOutput = new byte[photoOutputNsData.Length];
Marshal.Copy(photoOutputNsData.Bytes, rawOutput, 0, Convert.ToInt32(photoOutputNsData.Length));
return rawOutput;
}
}
}
}
}
}
}
So I made a small application that basicaly draw a whatever image is in the ClipBoard(memory) and trys to draw it.
This is a sample of the code:
private EventHandler<KeyEvent> copyPasteEvent = new EventHandler() {
final KeyCombination ctrl_V = new KeyCodeCombination(KeyCode.V, KeyCombination.CONTROL_DOWN);
#Override
public void handle(Event event) {
if (ctrl_V.match((KeyEvent) event)) {
System.out.println("Ctrl+V pressed");
Clipboard clipboard = Clipboard.getSystemClipboard();
System.out.println(clipboard.getContentTypes());
//Change canvas size if necessary to allow space for the image to fit
Image copiedImage = clipboard.getImage();
if (copiedImage.getHeight()>canvas.getHeight()){
canvas.setHeight(copiedImage.getHeight());
}
if (copiedImage.getWidth()>canvas.getWidth()){
canvas.setWidth(copiedImage.getWidth());
}
gc.drawImage(clipboard.getImage(), 0,0);
}
}
};
This is the image that was drawn and the correspecting data type:
A print from my screen.
A image from the internet.
However when i copy and paste a direct raw image from paint...
Object Descriptor is an OLE format from Microsoft.
This is why when you copy an image from a Microsoft application, you get these descriptors from Clipboard.getSystemClipboard().getContentTypes():
[[application/x-java-rawimage], [Object Descriptor]]
As for getting the image out of the clipboard... let's try two possible ways to do it: AWT and JavaFX.
AWT
Let's use the awt toolkit to get the system clipboard, and in case we have an image on it, retrieve a BufferedImage. Then we can convert it easily to a JavaFX Image and place it in an ImageView:
try {
DataFlavor[] availableDataFlavors = Toolkit.getDefaultToolkit().
getSystemClipboard().getAvailableDataFlavors();
for (DataFlavor f : availableDataFlavors) {
System.out.println("AWT Flavor: " + f);
if (f.equals(DataFlavor.imageFlavor)) {
BufferedImage data = (BufferedImage) Toolkit.getDefaultToolkit().getSystemClipboard().getData(DataFlavor.imageFlavor);
System.out.println("data " + data);
// Convert to JavaFX:
WritableImage img = new WritableImage(data.getWidth(), data.getHeight());
SwingFXUtils.toFXImage((BufferedImage) data, img);
imageView.setImage(img);
}
}
} catch (UnsupportedFlavorException | IOException ex) {
System.out.println("Error " + ex);
}
It prints:
AWT Flavor: java.awt.datatransfer.DataFlavor[mimetype=image/x-java-image;representationclass=java.awt.Image]
data BufferedImage#3e4eca95: type = 1 DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=0 IntegerInterleavedRaster: width = 350 height = 364 #Bands = 3 xOff = 0 yOff = 0 dataOffset[0] 0
and displays your image:
This part was based in this answer.
JavaFX
Why didn't we try it with JavaFX in the first place? Well, we could have tried directly:
Image content = (Image) Clipboard.getSystemClipboard().getContent(DataFormat.IMAGE);
imageView.setImage(content);
and you will get a valid image, but when adding it to an ImageView, it will be blank as you already noticed, or with invalid colors.
So how can we get a valid image? If you check the BufferedImage above, it shows type = 1, which means BufferedImage.TYPE_INT_RGB = 1;, in other words, it is an image with 8-bit RGB color components packed into integer pixels, without alpha component.
My guess is that JavaFX implementation for Windows doesn't process correctly this image format, as it probably expects a RGBA format. You can check here how the image is extracted. And if you want to dive into the native implementation, check the native-glass/win/GlassClipboard.cpp code.
So we can try to do it with a PixelReader. Let's read the image and return a byte array:
private byte[] imageToData(Image image) {
int width = (int) image.getWidth();
int height = (int) image.getHeight();
byte[] data = new byte[width * height * 3];
int i = 0;
for (int y = 0; y < height; y++) {
for (int x = 0; x < width; x++) {
int argb = image.getPixelReader().getArgb(x, y);
int r = (argb >> 16) & 0xFF;
int g = (argb >> 8) & 0xFF;
int b = argb & 0xFF;
data[i++] = (byte) r;
data[i++] = (byte) g;
data[i++] = (byte) b;
}
}
return data;
}
Now, all we need to do is use this byte array to write a new image and set it to the ImageView:
Image content = (Image) Clipboard.getSystemClipboard().getContent(DataFormat.IMAGE);
byte[] data = imageToData(content);
WritableImage writableImage = new WritableImage((int) content.getWidth(), (int) content.getHeight());
PixelWriter pixelWriter = writableImage.getPixelWriter();
pixelWriter.setPixels(0, 0, (int) content.getWidth(), (int) content.getHeight(),
PixelFormat.getByteRgbInstance(), data, 0, (int) content.getWidth() * 3);
imageView.setImage(writableImage);
And now you will get the same result, but only using JavaFX:
ABCpdf is not supported the https images , when we generate the pdf we will get the cross symbols.
Please help me .

I have my code That consist: I open the images that I want to upload, then I convert it in grayscale and later in binary image. But I have a question. How do I get values (0,1) of binary image in order to create a matrix with that values with emgucv c#??
OpenFileDialog Openfile = new OpenFileDialog();
if (Openfile.ShowDialog() == DialogResult.OK)
{
Image<Gray, Byte> My_Image = new Image<Gray, byte>(Openfile.FileName);
pictureBox1.Image = My_Image.ToBitmap();
My_Image = My_Image.ThresholdBinary(new Gray(69), new Gray(255));
pictureBox2.Image = My_Image.ToBitmap();
}
}
Second Post
I think I misunderstood the question, sorry for giving wrong info. But I think you may get some understanding from this post? Work with matrix in emgu cv
First post
By passing your My_Image which is result after ThresholdBinary() to following function, you can have array of zero and one only about the binary image.
public int[] ZeroOneArray(Image<Gray, byte> binaryImage)
{
//get the bytes value after Image.ThresholdBinary()
//either 0 or 255
byte[] imageBytes = binaryImage.Bytes;
//change 255 to 1 and remain 0
var binary_0_Or_255 = from byteInt in imageBytes select byteInt / 255;
//convert to array
int[] arrayOnlyOneOrZero = binary_0_Or_255.ToArray();
//checking the array content
foreach (var bin in arrayOnlyOneOrZero)
{
Console.WriteLine(bin);
}
return arrayOnlyOneOrZero;
}
Is this what you want? thanks
Third Post
By understanding this, chris answer in error copying image to array, I write a function for you to transfer your gray binary image to gray matrix image
public Image<Gray, double> GrayBinaryImageToMatrixImage(Image<Gray, byte> binaryImage)
{
byte[] imageBytes = binaryImage.Bytes;
Image<Gray, double> gray_image_div = new Image<Gray, double>(binaryImage.Size);//empty image method one
//or
Image<Gray, double> gray_image_div_II = binaryImage.Convert<Gray, double>().CopyBlank();//empty image method two
//transfer binaryImage array to gray image matrix
for (int i = 0; i < binaryImage.Width; i++)
{
for (int j = 0; j < binaryImage.Height; j++)
{
if (imageBytes[i*binaryImage.Width+j] == 0)
{
//grey image only one channel
gray_image_div.Data[i, j, 0] = 0;
}
else if (imageBytes[i*binaryImage.Width+j] == 255)
{
gray_image_div.Data[i, j, 0] = 255;
}
}
}
return gray_image_div;

Using processing I am trying to run a script that will process a folder full of frames.
The script is a combination of PixelSortFrames and SortThroughSeamCarving.
I am new to processing and what I want does not seems to be working. I would like the script to run back through and choose the following file in the folder to be processed. At the moment it stops at the end and does not return to start on next file (there are three other modules also involved).
Any help would be much appreciated. :(

essentially I want to do the same thing only with a different image process but my code is not doing this to all with in the folder... just one file.
You seem to be confused about what the setup() function does. It runs once, and only once, at the beginning of your code's execution. You don't have any looping structure for processing the other files, so it's no wonder that it only processes the first one. Perhaps wrap the entire thing in a for loop? It looks like you kind of thought about this, judging by the global variable i, but you never increment it to go to the next image and you overwrite its value in several for loops later anyway.
