I would like to sharpen an image using pure vb with no filters or unsharp method.Then use a track bar to slide through so that the image in the second picture box shows the effects of sharpening, up and down. I have the code below but it gives me errors:
Private Sub Sharpen() Dim fpixel, secpixel As Color Dim NewImg As Bitmap = New Bitmap(PicBefore.Image)
I have the code below and would like to sharpen the image in the increments of 10% starting at 0% to 100%. How do i apply separate filters so that when i move the track bar, i am able to see the effects take place step by step?
Private Sub TrackBar1_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TrackBar1.Scroll Dim sharpness As Single = CSng(TrackBar1.Value / 100) ' no change in brightness
Know how to use the track bar to control the brightness or darkness of an image in a picture box,use track bar to sharpen an image and to use trackbar to emboss an image.
how to tell VB to take two images and blend them together. Similar to how Windows 7 does it's wallpaper fade when it switches wallpapers. For now I found the program Image Magick can do that with the composite command. I'm trying to do something like this:
SH = CreateObject("WScript.Shell") for x=10 to 100 step 10 SH.Run("%comspec% /c composite -blend " & x & " -gravity South img1.jpg img2.jpg -matte blend.jpg") SetWallpaper("blend.jpg") next
I am working on the listview that I have got two columns, the one that it goes for the images and the other one goes for the text data. I can extact the text data, but not for the images.
I am working on button component, and I would like to get up and down arrow keys on the button, and on the click event of these arrow keys to display the images, proposed functionality in the form can be done further. I want to display an image with the text and the arrow keys to display the images when I click on the button like this:
I playing a video with Microsoft.Directx.AudioVideoPLayback. My code is pretty simple: I create a Video object wich opens an avi movie, I assign its owner property to panel1 control and then I play the movie.I want to capture images every second from the movie that is being played.I try with panel1's DrawToBitmap() method and then saving the drawn bitmap, but it just draw the panel1, not the image.Is there a way of doing it?.
I'd like to move my images / icons and wav files (basically, almost all of my internal resources) from an existing project (VB 2005) and put them in an external dll, then reference this from my exe and call the relevant resource as required.
What would be the best way of doing this?I understand that I should create a ClassLibrary and put my resources in that, but how should I expose those resources to an external program and how should I reference and call the dll from my exe?
I've done some searching, but not found anything that seems to explain the process adequately enough.
i want to make an application that will display new images from a camera at the time they are taken.The camera will be connected with USB to the computer.I thought to set a FileSystemWatcher that will monitor for new image fileson the camera and then copy those images and display them.But i searched a little bit and i found a WIA library on msdn
how do you make images transparent in vb 2005? i have a bunch of images that i want to use, but they all have a white square background. How would I get rid of its white square background?
Is it possible to set the image windows displays when viewing a file created in a VB.NET application? In my case I have files saved that store info on football plays for a play creator program. Can I use the image of that play as what the user will see when he searches through windows explorer?
Let me further explain with an analogy: photo files in windows have their images displayed as the user cycles through them; he chooses which one he wants to doubleclick based on the thumbnail image of the actual photo. I'd like to have a "photo" of the play itself shown instead of what is now just a blank generic grey icon for the play files that I save.
now the remaining things are done-able but im stuck in new requirement posted by Client which he needs to upload all images from Sql Server to Oracle Database now since old application stores images Path it is kind of new story now ?(:
i tried to build sample application since am not familiar with kind of above requested modification here is my code so far to upload images
'' Sql connection is over Dim fs as new fileStream (imgPath , io.fileMod.Open , Io.FileAccess.Read) Dim imgByte (fs.length -1 ) as byte
when i connect my digital camera (Canon) to the computer i can see it in the windows explorer root folder but i cannot access it using the System.IO.GetDrives() function. Is there a way to access my digital camera programmatically ? I mean via windows explorer i can , why not using .NET ?
I'm experimenting with the RichTextBox control. My goal is to replace certain user input with an image object. For example, when the user used ":-)" in the RichTextBox it will be replaced with a simple image (like ).
I use the TextChanged event on the RichTextBox to replace any found textual smiley with an image. The code below works, but only works on the first found ":-)". When the user used ":-)" twice the first image is being removed from the RichTextBox. No matter howmuch times ":-)" is found, there will only be one image in the RichTextBox (for the last found ":-)").
Private Sub RichTextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged Dim LastIndex As Integer
[Code]....
I also don't know if the whole clipboard thing (clearing it, storing the image, restoring the original data) is the best way to do it, but I will look at that later.
I have 22 images and I am trying to add them into an array and then assign them randomly to a button so when the button is pressed it will change to the assigned image. Also is it possible to randomize the array.
I have got a problem with the regex pattern. I couldn't be able to extract the id in the images tags from the html source when I find the matches pattern that I selected on the listview items. [code] It have found the matches with the html tags, but it doesn't extract the id from the images tags. [code] Do anyone know how I can extract the id in the images tags from the html source?
Does anyone have any suggestions how I might store the contents of a RichTextBox that also includes images to a MSSQL 2005 database?I suppose a possible answer to this would be to convert the entire content of the RichTextBox to a Byte Array, and then insert the array as a varbinary(max) datatype.But how do I convert the content ?
My app deals with football, and the line of scrimmage. There is an additional line, called the line to gain, used for showing where a first down is earned. I'd like to have a trackbar with two arrow on it... one for the Line of Scrimmage, and the other for the Line to Gain.
I need to use a trackbar as a scrollbar, but the problem is that the min value is at the bottom i need it to be 0 at the top and maxvalue at the bottom..
Im working on a Music player. I need only 2 more things in it but i cant figurate 'em out. i use a LISTBOX for the playlist. I want to add a trackbar that follows the music and i can track with it (like every music palyer). The second thing is i want the palyer to start the selected file if i duble-click on it in the playlist. [code]
know the millisecond interval, used by the framework trackbar, between calling the ValueChanged event when moving the grip with a mouse?I've implemented my own trackbar and I'd like the behaviour to be consistent with what the user expects.I've had a look in reflector but it's one of those controls where most of the implementation is not viewable.
ETA: Actually, thinking about it, it's not as simple as that. For small changes, the TrackBar is raising the event for every change. However, if you make a large fast change with the grip, it will not raise the event for every step. Just wondering exactly how the framework does this?
