I have a code that sharpens an image using the 'unsharp method' when a button is clicked and filters applied.
Apply unsharp masking.
Private Sub btnUnsharp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUnsharp.Click
[code]....
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)
[code]....
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
[code].....
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.
View 6 Replieshow 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
But so far no dice.

View 1 RepliesI'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.

View 1 RepliesIs 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.

View 1 RepliesI'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 ":-)").

View 7 Repliesknow 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?
