I use the imagebox to display a image(imgWidth:19200, imgHeight:260),and my code is:
imageBox = new ImageBox();
imageBox.Size = new Size(imgWidth, imgHeight);
imageBox.Dock = DockStyle.Fill;
MainSplitContainer.Panel1.Controls.Add(imageBox);
imageBox.Image = new Image<Bgr, byte>("2.bmp");
But the displayed image width is only about 15000, and the right part of the image can not be displayed. How can I display the full image?
It is possible that an ImageBox won't do more than 15,000 pixels in width. However, have you tried setting the functional mode to Pan and Zoom? Maybe that will get you there.

I'm trying to add .ico 48x48 image before text in WinForms button 87x30 size:
button1.BackgroundImageLayout = ImageLayout.Stretch;
button1.BackgroundImageLayout = ImageLayout.None;
button1.BackgroundImageLayout = ImageLayout.Zoom;
button1.ImageAlign = ContentAlignment.MiddleLeft;
button1.TextImageRelation = TextImageRelation.ImageBeforeText;
button1.TextAlign = ContentAlignment.MiddleRight;
Result is:
I'm trying to figure out, how to align image on the left side with text on related distance, like this:
edit:
button1.TextImageRelation = TextImageRelation.ImageBeforeText;
button1.TextAlign = ContentAlignment.MiddleLeft; /// MiddleRight; // MiddleCenter;
button1.ImageAlign = ContentAlignment.MiddleRight; /// MiddleLeft;
Result:
The background image property is like the operating system desktop background, it is a wallpaper, that can be stretched, adapted, repeated...
Therefore here you don't need to use BackgroundImage for a button icon style image associated to its text.
If you use the Image property and set alignments to left for it and right for text, all works fine:
Then you can adapt these alignments as well as width and height to the desired result depending on the image size and/or text size and length.
Also, as indicated by the duplicate I finally found, to simply center all, you can use the TextImageRelation and set it to TextImageRelation.ImageBeforeText without changing alignments, and if necessary by increasing the height according to the size of the displayed image to have a clean result:
I'm writing a little program that tranfers a screen shot of a user screen to my wpf image control but when the image is displayed it is not full,not the whole screen is displayed even if the action was done through my computer and not my leptop and it is blurry
Bitmap bmp=
new Bitmap((int)SystemParameters.PrimaryScreenWidth(int)SystemParameters.PrimaryScreenHeight);
Graphics g = Graphics.FromImage(bmp);
g.CopyFromScreen(0, 0, 0, 0, bmp.Size);
the code above is the code to take the screenshot
BitmapImage bmI = new BitmapImage();
bmI.BeginInit();
bmI.UriSource = new Uri(FullPath);
bmI.EndInit();
Screen_Shot.Source = bmI;
And this code is the code to dislpay the image, Screen_Shot is the image name, and the full path is where i put the bitmap image
I tried to use
Screen_Shot.Stretch = Stretch.Fill; and UseLayoutRounding="True" SnapsToDevicePixels="True"
but none of them seems to get the job's done
this is an exsample of a screenshot i took from my own pc
You want to set the Stretch property to Uniform or else your image will be distorted as it will fill regardless of the Image control's size/shape. You also have to remember that the screen size may be different than your programs window size. If you don't uniformly stretch the image it will distort almost always (even if it's just a bit).
Regarding your "blurry" image, you need to specify the rendering option of you Screen_Shot image control or it will set the image to a lower quality that it can render more easily. This is honestly better to just set in the xaml. I normally use Fant, but look other options specified here.
<Image Name="Screen_Shot" RenderOption.BitmapScalingMode="Fant"/>
i create a panel and inside this panel i create a picture box. this have no default image. after a function i load a image und put it into this picturebox. the image was bigger as the panel and i want to scroll the image but the image draw only in the first area to see and if i scroll the image dont draw complete. how i can fix this ?
Image TreeImg = new Bitmap(imgPath);
maletreePictureBox.Width = TreeImg.Width;
maletreePictureBox.Height = TreeImg.Height;
maletreePictureBox.Image = TreeImg;
actionPanel.AutoScrollMinSize = new Size(TreeImg.Width, driverTreeImg.Height);
this is the result
Set the .Dock property of the maletreePictureBox to Fill.
Also it looks like your AutoScrollMinSize Height property is incorrect (driverTreeImg.Height instead of TreeImg.Height)
I want to show a background image on my app's navigation bar.
Showing the image works:
UIImage image = new UIImage( #"Images/navbarlogo2.png");
UIImageView imageview = new UIImageView(image);
NavigationItem.TitleView = imageview;
But the image is centered, while I need it to be right-aligned.
I have not been able to find a property to do this, and searching yielded no answers.
You could use the following method to set your navbar's background image. Note that this will set it as the default for all the nav bars and is available since iOS5.
UINavigationBar.Appearance.SetBackgroundImage(image, UIBarMetrics.Default);
I am loading multiple images into a picturebox one at a time. Each time the image is loaded in using code like this:
pBox1.Size = new System.Drawing.Size(450, 450);
pBox1.SizeMode = PictureBoxSizeMode.CenterImage;
pBox1.BorderStyle = BorderStyle.Fixed3D;
pBox1.SizeMode = PictureBoxSizeMode.StretchImage;
pBox1.Image = (Image)image;
pBox1.Refresh();
Most images that have the same height as width show up fine, however images that have different heights and weights are skewed. How would I handle images like this to show up correctly?
well for one you first set sizemode to CenterImage then set it to StretchImage overwriting what has been first set. but i would set it to zoom.
You probably want to use Zoom for PictureBoxSizeMode. That will uniformly stretch the image:
pBox1.SizeMode = PictureBoxSizeMode.Zoom;
