You can check the memory increase but the GC eventually clears it out. Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load Science fiction (sometimes shortened to sf or sci-fi) is a genre of speculative fiction, which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life.Science fiction can trace its roots to ancient mythology. G.DrawString(Guid.NewGuid().ToString(), New Font("Arial", 24, FontStyle.Bold), Brushes.Green, 400, 100) Using g As Graphics = Graphics.FromImage(bmCopy) Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tickĭim bmCopy = DirectCast(images(findex).Clone(), Bitmap) I made something along the lines of what you have (I think), where we use Object.Clone to make a copy in memory of each bitmap which you can modify without modifying the original image. Dim ms As MemoryStream New MemoryStream newimage.Save (ms, .jpeg) Dim b () As Byte ms.ToArray response.binarywrite (b) The above code can be added onto the end of the asp.net page to finally convet the image to a binary array and write back the jpeg image. This takes the text, font object, brush and coordinates as parameters. The irony is that if you did actually load the image each tick, then you wouldn't actually have this problem :) Text is drawn in Visual Basic using the DrawString() method. So you end up with text repeatedly being written over itself. Powerful VB.NET image drawing SDK that enables programmers to draw rich graphics on target image file. Subtract that from the PictureBoxs width and. Remember this is a reference type so the original items gets modified. To center the text horizontally, use the PictureBoxs TextWidth method to see how wide the text will be. The distinction is you keep references to these images and you are modifying each one. Do you really load each image by filename each time you show it? That's misleading, as you mentioned there is an array. I think it's important how you load the images. In any case, i need to stop the memory bleed. Or even better, don't use a PictureBox at all, just display images with text overlay? I need the images to display in the picturebox one at a time using the timer and I need to overlayĬan someone help me stop the images from adding to the picturebox instead of displaying one at a time? You need to set up a font object, a solid brush to draw the text, as well as setting up any optional string formats you may require. G.DrawString("Kishman Tukus", New Font("Arial", 24, FontStyle.Bold), Brushes.Green, 400, 100) Here is the code I am using to create images and text Dim fname As String = (Actually an array in images(jpg) that display with timer)ĭim g As Graphics = PicBox.CreateGraphics The images seem to be adding on top of each other instead of displaying one, then removing that one, and loading another.Īs the images are displayed, I would like to overlay text on the images.
