How do I flip the image upside down (below the first image) Like as if a house were at the waters edge and you can see the house, and the reflection in the water?
code for drawing the image (which is a battery)
VB
'Finding center'
Dim batX As Integer = 160 - (imgDct(cbo_Battery.Text).Width / 2)
Dim batY As Integer = 200 - (imgDct(cbo_Battery.Text).Height / 2)

this code currently takes a jpeg image [] and copys the left half and pastes it over the right half so its like this [[. I need to modify this code so that the right half flips to form a mirror image with the left half,
Dim mb, rb, cb As Bitmap
lblMid.Image = Image.FromFile(tbFileName.Text)
mb = Bitmap.FromFile(tbFileName.Text)[code]....
This is in a class, the class inherits Panel. VB.net

The goal is to have this image stretched to 300x50 Whenever I do it, it works, but it fades the image from left to right, so that at Left = 0, the image is solid, but at Left = 300, the image is transparent.
I have tried to realign the image by down and right one pixel, but still only part of the first row and column are visible when zoomed.I can't find exactly what I'm looking for online.

Well currently im programming a game in Visual Basic and I have it to the point where it draws a map on the form, it loads maps to different areas when you walk on the map, and I am doing so by using Graphics. DrawImage which redraws the map on the screen with the character in the new position. It was working quickly and smoothly until now.
I added some more sprites and now it starts to lag badly then it will throw a Out of Memory exception and it will display a big red x across the form. I watched the memory now as i move the character one spot on the forum and the memory increases 100mb's each time. It wasn't doing this before which is weird. I managed to fix the out of memory error using GC.GarbageCollect but I read that this is bad, also the character still lags across the forum. I really didn't want to release the source code until I was finished but seeing as I need help quickly because this is for a project I am working on for Thursday (End of semester Programming 2 Junior year of high school) I don't have many options.
Graphics.DrawImage loses resolution
View 13 RepliesI'm trying to improve the speed of my call to:Graphics.DrawImage (Image, Rectangle, Int32, Int32, Int32, Int32, GraphicsUnit, ImageAttributes)I want to display two images, where the old one fades smoothly into the new one, driven by a Timer tick of 10 or 20 ticks a second. The following code runs fine on JPEG files of around half a megabyte or less, but takes much too long (up to half a second) fora 2MB JPEG. Using the Stopwatch control, I isolated the problem to the two .DrawImage calls. Do I need to do this in DirectX or is there a way to improve the efficiency of the routine? I thought of trying to resize the two images beforehand to fit the rectangle, but that's not a simple call (I don't think), and it might just mean moving the delay elsewhere.

I need to draw a bitmap background with one or more moving bitmaps in the foreground; something like a chessboard where pieces move across it. I use a timer-tick event to redraw the background and then draw the relocated foreground image like the code below. But I get flicker, even though I set the form to use double-buffering. The culprit seems to be redrawing the background to refresh where the foreground images used to be; no flicker if I replace the background DrawImage with a simple Graphics.Clear. I think what I want to do is draw the background, and the foreground bitmap(s), in memory and then render it all. I used to do this with double-buffering, BitBlt, and .Refresh in VB6 but I haven't found the equivalent in VB2010. This must be a pretty common graphics requirement; what's the trick to it?
Dim Gfx As Graphics
Me.SetStyle(ControlStyles.AllPaintingInWmPaint Or ControlStyles.UserPaint Or ControlStyles.OptimizedDoubleBuffer, True)

I load my picturebox with a jpeg. If I put my DrawObjects() sub into picturebox paint event.When ever a picturebox.refresh or picturebox.visible = true (vb.net seems to draw my DrawObjects() first, then load the jpeg Image over my drawing - erasing drawing) Is there a way to get the picturebox to redraw the jpg image first then draw on it, in picturebox paint event?
View 10 RepliesI'm a VB beginner.I've been playing with Graphics.DrawString by watermarking a picture with a text string. The picture below to the left comes from PictureBox with a text string drawn with Graphics.DrawString. The font style used is Arial 48 points, regular, I think. The picture in PictureBox shows just as I configure. Great... The resolution of the original Terri Hatcher picture is 300 dpi (300 x 300). Exporting this picture with Graphics.DrawString, I get the picture below to the right. The text string appears a lot bigger than previously shown in PictureBox. It turns out that the text size varies, depending on the resolution of the original picture. That's kind of odd. I develop several graphics applications in a different environment and have never seen this sort of graphics.drawstring thing. Anyway,

I would like to create a reflection of a text on an image. I have used so far this:

for example a g. transform used with matrix could do that
I created a form with MS Access with some dropdown menus and some check boxes. The main reason is for when the user select a check box or an option from the dropdown menu a specific phrase will appear on a Note box I created on the bottom of the form. Where I am having the problem is because I added a Text Box in Access where the user can type something in it. What I need is when something is typed inside of the text box the content should be mirrored inside of the Note Box on the bottom of the form. I was able to create the functions using VB for the dropdown menus and the check boxes but for the Free Form Text Box I dont know how to mirror the real time texting.
View 3 RepliesI have two textbox controls and I want to accept input for textbox 1 and textbox 2. However, when user enters text into textbox 1 I would like textbox 2 to mirror the same text as it is typed. I am sure this is a very simple procedure however it is new to me and I am having trouble finding an answer with search engines. Most result are coming back as text that one can read backwards in a mirror which is not what I am looking for.
View 1 RepliesI have a very annoying problem, I am trying to draw an image with the Graphics class but when I do DrawImage, it automatically scales it up! heres some example code
graphics.DrawImage(My.Resources.TestImage, 20, 20)
PictureBox1.Image = My.Resources.TestImage
The picture box image is the correct size whereas the graphics drawn verison is too big!
I made a program that uses the graphics object to draw on a picture box. I used the graphics.fromhwnd(picbox) to draw on the control. The problem is if I minimize the window the drawing disapears. Might there be a way I can the image from the picbox and save it to a bitmap variable ?

View 3 RepliesI am creating an application where when I click on an image I need to mark the place using the x and y co-ordinates given by the click and then after marking I put a red dot/circle on that spot and then I need to save this image to a file including the dot/circle I marked. I have tried saving the image to the file but to no avail, I have been able to only save the PictureBox image and that doesn't include the graphics. It is only the base image. I have tried to save it as a bitmap but have not gotten anywhere with that either. It seems whenever I call the image.save it takes only the value of the underlying image and saves it.

I am building a program which offers solutions to the travelling salesman problem (finding shortest tour between a set of cities while visiting each only once).
My program loads a bitmap image of a map into a picture box. From there, graphics which point out the cities as well as tour paths are drawn onto the map. My problem is that when the option to plot ALL cities is enacted, the user may choose to pinpoint a specific city with a separate control. When the user erases that pinpoint via an invalidation routine, though, it erases all graphics beneath it, which is undesirable. How can I make my tour graphics and city plots semi-permanent by drawing them directly on the image? I tried drawing them on a separate bitmap, but it 'covered up' the map image.

I have an application that downloads a .jpg snapshot from an IP camera, writes it to the server hard drive, attaches it to an email and sends it out to my users. Pretty simple until one guy had to mount his camera upside down and that's how he received the image via email.
It gets a bit annoying after a while, so he asked me if I could rotate it 180 degrees before attaching it to the email. I have absolutely no idea - hence my post. The app is on a hosted ASP.Net v3.5 web server.

But I am zooming the image using,e.Graphics.DrawImage(Picturebox.Image, New Rectangle(ZoomXCordinate, ZoomYCordinate, ZoomWidth, ZoomHeight)).Now I am not getting how to get the raw data of zoomed graphics image displayed on the Picturebox.I am actually trying to get the image data into a byte array.
View 5 RepliesI am using VB.NET to try and capture a portion of the screen so I found this code in several places to capture the whole screen:
Dim screenSize = SystemInformation.PrimaryMonitorSize

g.CopyFromScreen(New Point(0, 0), New Point(0, 0), screenSize)
End Using
bitmap.Save("c:scratchscreenshot.png", System.Drawing.Imaging.ImageFormat.Png)
This works with no error throw and the file is created successfully but the resulting image is completely transparent (it is the correct size) - This question relates to the same error but the solution is to use Win32 GDI which I want to avoid if possible
