由 徘徊边缘 提交于 2019-12-07 22:32:38
问题 I'm not really sure if it is possible to insert a part of image into picturebox, but I would like to create an image 500*500 pixels in size and then use the parts of it as small connectable 50*50 pieces by setting the location of image inside the pictureboxes... Is anything similar possible through use of graphics? I'm not very familiar with it... (I am talking about C# forms application...) 回答1: After some time of searching and few personal attempts I have found a solution, this isn't my own

Overlay two or more Bitmaps to show in Picturebox (C#)

由 偶尔善良 提交于 2019-12-07 03:44:46
问题 In my C# program I have a Picturebox in which i want to show a stream of video (consecutive frames). I receive raw data, that I then transform into Bitmap or Image. I can show one image at a time without a problem (to reproduce the video stream). Now my issue is that I want to merge 2 or more bitmaps (like layers) with the same size and alpha values (ARGB) and show it on the picturebox . I have read lots of websites and posts here on SO, but many use the Graphics class, and I just can't draw

问题 I want to make the background of a PictureBox control transparent. In the PictureBox (rectangular shape), I placed an icon (circular in shape). I want to make the icon transparent so that the other portion underneath the icon is visible. I have tried setting the PictureBox.BackColor property to "Transparent", but it doesn't work. I also tried to set it during runtime with the Color.FromArgb method, but it doesn't work either. Is there any solution to this problem? 回答1: Setting pictureBox

问题 I have a program in C# with a PictureBox object inside a Form . How do I change its picture? The pictures to chose from are in bin/Pics; they are jpeg in format, if that matters.. 回答1: Assign a new Image object to your PictureBox 's Image property. To load an Image from a file, you may use the Image.FromFile method. In your particular case, assuming the current directory is one under bin , this should load the image bin/Pics/image1.jpg , for example: pictureBox1.Image = Image.FromFile("..

Picture box transparency in vb

由 故事扮演 提交于 2019-12-06 15:35:56
When i run my code, the picture box has a background colour, even though I have set the background colour to transparent in the properties window. any ideas? I assume you're overlapping a PictureBox over some other control and expecting to see through the PictureBox . That's not how it works - controls with transparent backgrounds are only transparent relative to their parent, not other controls. You could draw them using GDI+ by overriding the OnPaint method of your form: Private Shared ReadOnly SomeImage As Image = My.Resources.blah 'Get your image somewhere Protected Overrides Sub OnPaint

C# Panel.BackgroundImage + transparent Controls = flickering?

问题 I've got a Panel with a jpg BackgroundImage (with BackgroundImageLayout = Stretch ). On the panel it's Controls I add some PictureBoxes with a PNG which has transparent borders. Displaying this doesn't give any problems, but moving (the boxes are draggable) the PictureBoxes does. The result is that the moving PictureBox "disturbs" the BackgroundImage and slows down performance. The faster I drag the box, the more it disturbs the BackgroundImage , and vice versa.

问题 I am trying to write some text over my picturebox so I thought the easiest and best thing to do is draw label over it. This is what I did: PB = new PictureBox(); PB.Image = Properties.Resources.Image; PB.BackColor = Color.Transparent; PB.SizeMode = System.Windows.Forms.PictureBoxSizeMode.StretchImage; PB.Size = new System.Drawing.Size(120, 30); PB.Location = new System.Drawing.Point(100, 100); lblPB.Parent = PB; lblPB.BackColor = Color.Transparent; lblPB.Text = "Text"; Controls.AddRange(new

Windows Forms: How to directly bind a Bitmap to a PictureBox?

由 霸气de小男生 提交于 2019-12-06 11:20:11
I'm just trying to build a small C# .Net 4.0 application using Windows Forms (WPF I don't know at all, Windows Forms at least a little :-) ). Is it possible to directly bind a System.Drawing.Bitmap object to the Image property of a PictureBox ? I tried to use PictureBox.DataBindings.Add(...) but this doesn't seem to work. How can I do this? Thanks and best regards, Oliver This works for me: Bitmap bitmapFromFile = new Bitmap("C:\\temp\\test.bmp"); pictureBox1.Image = bitmapFromFile; or, in one line: pictureBox1.Image = new Bitmap("C:\\temp\\test.bmp"); You might be overcomplicating this -
