I'm trying to use PictureBox object in order to display an image, but i get some "errors" . If i just add the PictureBox attributes (location, image, size, backColor etc... ) i don't see any image
I then read i need to add the PictureBox to the Form Controller.
I added it and yet, still nothing ... is there any priority of the layers (what in the back what in the front ?, how can i change it ?)
here is the attributes set of the PictureBox:
imageFile = new PictureBox();
imageFile.Top = 200;
imageFile.Left = 400;
imageFile.Height = 100;// furnitureSize.Height;
imageFile.Width = 100;// furnitureSize.Width;
imageFile.ImageLocation = (Application.StartupPath + "\\ball4.gif");
imageFile.Image = Image.FromFile(Application.StartupPath + "\\lamp3.jpg");
imageFile.Visible = true;
imageFile.BackColor = Color.Black;
imageFile.SizeMode = PictureBoxSizeMode.StretchImage;
ownerForm.Controls.Add(imageFile);
imageFile.Show();
Please help.
Hmm... are you sure you meant
ownerForm.Controls.Add(imageFile);
and not
this.Controls.Add(imageFile);
?
The problem was as i thought ( the pictureBox wasn't in the front)
adding : imageFile.BringToFront(); solved the issue
Thank you all.
You must define size to your picturebox
imageFile.ClientSize = new Size(100, 100);

I want to place a Label on top of a gif inside a PictureBox in winforms.
The problem ist that the label has a white background. I want it to be transparent.
My Code is as follows:
this.pictureBox = new PictureBox();
this.pictureBox.Image = Image.FromFile("my_background.gif");
this.pictureBox.Dock = DockStyle.Fill;
this.pictureBox.SizeMode = PictureBoxSizeMode.StretchImage;
this.label = new Label();
this.label.Text = "Hallo";
this.label.BackColor = Color.Transparent;
this.label.Location = new System.Drawing.Point(100, 100);
this.Controls.Add(this.label);
this.Controls.Add(this.pictureBox);
My problem is that the Label has a white Background even though the background is set to transparent. The solution for other having a similar problem was setting the parent of the label to the picture Box like this:
this.label.parent = this.pictureBox;
But that didn't solve the problem for me. Is there any other way to achieve this?
Thanks for any answers.
Thanks for the hint.
It worked fine when putting only a view controls in front of the gif. When adding to many it got very buggy and only some rectangular parts of the gif would update.
I solved the problem by splitting my gif into single images and displaying them in the OnPaint Event of the form
this.Paint += new PaintEventHandler(this.Paint_Background);
The Paint Method looked like this.
private void Paint_Background(object sender, PaintEventArgs e)
{
Graphics background_graphics = e.Graphics;
Graphics graphicsObj;
graphicsObj = this.CreateGraphics();
int image_num = ((int)((DateTime.Now - start_time).TotalMilliseconds) / gif_speed) % num_images;
Image background= Image.FromFile("Filename_"+image_num+".jpg");
background_graphics.DrawImage(background, 0, 0, ClientSize.Width, ClientSize.Height);
background.Dispose();
}
All of my Controls where added directly to the view and not the imagebox anymore, as the imagebox was removed entirely.
Maybe this can help someone else too
I created a PictureBox and load an image into it, and I wanted the pictures to have a maximum size (let's say 250px). Here is the code I'm using at that moment
PictureBox cellPictureBox = new PictureBox();
cellPictureBox.AutoSize = false;
cellPictureBox.Dock = DockStyle.Fill;
cellPictureBox.SizeMode = PictureBoxSizeMode.Zoom;
cellPictureBox.Image = Base64ToImage(data.ToString().Trim());
cellPictureBox.Width = 250;
cellPictureBox.Height = 250;
When I load the first image, it's quite large. When I load a second image, it's automatically scaled down to be very tiny, and the newly loaded image takesthe large size the first image had. This trend continues as I add more rows to my data.
What can I do to help manage the sizing of my images? Making a custom control I've been told is useful, but I don't see what is happening that I have wrong.
To set maximum and minimum sizes, have a look at the following:
PictureBox cellPictureBox = new PictureBox();
cellPictureBox.AutoSize = false;
cellPictureBox.Dock = DockStyle.Fill;
cellPictureBox.SizeMode = PictureBoxSizeMode.Zoom;
cellPictureBox.Image = Base64ToImage(data.ToString().Trim());
cellPictureBox.MinimumSize = new Size(100, 100); // or whatever size you want.
cellPictureBox.MaximumSize = new Size(250, 250);
If you only want to set a limit on one dimension, for example, the width, but the height is allowed to be anything, then use int.MaxValue:
cellPictureBox.MaximumSize = new Size(250, int.MaxValue);
I want copy image from one picturebox to another. The code below:
PictureBox pictureBoxRain1 = new PictureBox();
pictureBoxRain1.Size = size;
//pictureBoxRain1.Image = (Image)Properties.Resources.kaplja;
pictureBoxRain1.Image = Image.FromFile(#"C:\images\kaplja.png");
//pictureBoxRain1.ImageLocation = pictureBoxRain.I;
//pictureBoxRain1.Image = Graphics.FromImage();
//pictureBoxRain1.InitialImage = Properties.Resources.kaplja;
//pictureBoxRain1.BackgroundImage = Properties.Resources.kaplja;
pictureBoxRain1.Location = new Point(pictureBoxRain.Location.X + pictureBoxGrass.Size.Width + 10, pictureBoxRain.Location.Y);
Controls.Add(pictureBoxRain1);
All anothers properties copy perfectly to pictureBoxRain1 from pictureBoxRain, but image doesn't want show. Where is problem? I checked many variants such as copy image from Properties.Resources, and reading direct from file and some others(look comments in code above), but nothing works.
EDIT
Check the pictureBoxRain1.SizeMode.
I'm trying to fit image to button perfectly.
But the image is cropped on its right and bottom faces, see attached print screen:
I edited the button as follows:
var l_oStopImage = Image.FromFile(#"C:\Users\AmitL\Downloads\Button-2-stop-icon72p.png");
var l_oStopPic = new Bitmap(l_oStopImage , new Size(btnStopOperation.Width, btnStopOperation.Height));
btnStopOperation.Image = l_oStopPic ;
btnStopOperation.ImageAlign = System.Drawing.ContentAlignment.MiddleCenter;
btnStopOperation.TabStop = false;
btnStopOperation.FlatStyle = FlatStyle.Flat;
btnStopOperation.FlatAppearance.BorderSize = 0;
I also tried to edit the BackgroundImageLayout but none of the ImageLayouts fixed the problem..
Any suggestions?
Thanks in advance

You should use stretch, I suggest in designtime (this is not java where you have to add elements by code):
this.buttonOk.BackColor = System.Drawing.SystemColors.MenuHighlight;
this.buttonOk.BackgroundImage = ((System.Drawing.Image)(resources.GetObject("buttonOk.BackgroundImage")));
this.buttonOk.BackgroundImageLayout = System.Windows.Forms.ImageLayout.Stretch;
this.buttonOk.DialogResult = System.Windows.Forms.DialogResult.Cancel;
this.buttonOk.Location = new System.Drawing.Point(475, 15);
this.buttonOk.Name = "buttonOk";
this.buttonOk.Size = new System.Drawing.Size(50, 50);
this.buttonOk.TabIndex = 11;
this.buttonOk.UseVisualStyleBackColor = false;
this.buttonOk.Click += new System.EventHandler(this.buttonOk_Click);
And it will work, done it many times before
I got this code from my own working Form1.Designer.cs but because of that: please use the Visual Studio designer and don't try to write all this code / logic in your constructor or something.
The problem is because you are showing an image with the same size as your button.
When you want an image fit in your button, the width and height of image should be at least 1 point less than your button size. (or in other word, you can set your button width and height 1 point more than the image size).
So you can change your code to this:
var l_oStopPic = new Bitmap(l_oStopImage ,
new Size(btnStopOperation.Width-1, btnStopOperation.Height-1));
I want to create the image of a dynamically created usercontrol and show it in a window.
I am creating the usercontrol using the Below code .
MyViews.MyViewsUserControl myViewsCanvas = new MyViews.MyViewsUserControl(AllFoundationMyViewsViewModel,item.Id);
//myViewsCanvas.Height = 5;
//myViewsCanvas.Width = 5;
Size size = new Size(50, 50);
myViewsCanvas.Measure(size);
double width = myViewsCanvas.DesiredSize.Width;
double height = myViewsCanvas.DesiredSize.Height;
myViewsCanvas.Arrange(new Rect(new Point(), size));
Then i am creating the image of the myViewsCanvas and adding it to a view box of another usercontrol called _DashBoardUserControl using the below code.
_DashBoardUserControl.Viewbox2.Child = CreateImage(myViewsCanvas);
Then i am adding the _DashBoardUserControl to a window.
UserControls.Controls.PopupWindow popup = new UserControls.Controls.PopupWindow();
popup.PopupContent = _DashBoardUserControl;
popup.ShowDialog();
The problem is, I can only see a portion of the Image. I guess that is because of the measure() and arrange() methods. Can anybody tell me about these methods or what size should i pass to these methods. Do i need to scale down the image? If yes how do i do that?
The easiest way I know of is this:
Viewbox v = new Viewbox();
v.Child = uielem;
uielem.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));
v.Measure(uielem.DesiredSize);
v.Arrange(new Rect(new Point(), uielem.DesiredSize));
v.UpdateLayout();
r.Render(v);
where uielem is the element you want to render and r is the RenderTargetBitmap. (v.UpdateLayout might not be needed there, but I'm not sure anymore).
