I need to create high quality icons for my current project in vb.net
This is my code so far,
Private Sub CreateIcon(ByVal bitmapName As String)
Try
Dim fi As New System.IO.FileInfo(bitmapName)
[Code].....
But the problem is it only gives me a very low quality icon at the end. how to make a higher quality image?
I want to make a wallpaper changer because windows high compresses the the image so you see artifacts even if already use a jpeg or even a really high quality png or bmp.
I know what I need to do for all of it I just need to know how to save an image to a jpeg without it being compressed. I have tried using the encoderparamters and getcodecinfo aswell as setting the quality to 100 but I still get a really bad looking image in the end.
Is there a way where I can save an image to a jpeg without getting the crappy image quality like with visual basic?
I'm just curious how I get Windows to use the high quality cursor when dragging and dropping in my WPF application. What I mean by high quality is: Rather than the regular arrow with a rectangle. I tried using e.Effect but that didn't do anything... Am I doing something wrong? Or is this just how it is in WPF.

View 2 RepliesThere's a really simple way to convert images to icons:
Dim icon As Icon = Icon.FromHandle(bmp.GetHicon())
It also produces really horrible icons. Is there a better way to convert them, or more accurately, what is the better way to convert them?
The Vb.Net application creates a bitmap from scratch and either converts to a tiff or sends it to a printer. In both cases, the quality of the image (in this case the font) is not good at all. The sample code listed below creates the graphics object that I use to write to the image.
Dim gr2 As Graphics = Graphics.FromImage(New Bitmap(800, 1000), Imaging.PixelFormat.Format32bppPArgb))

I am trying to create a high scores board - currently i was experimenting with just typing a number into a textbox and having it automatically order the numbers (in labels) from largest to smallest however i cannot get them all to work. either just the first and second (label) works or the second and third display the same number or the second decreases in value even though it shouldn't[code]...

View 6 RepliesIm creating a quiz game although i was wondering if any one can teach/tell me how to create a high score system.For example when the user clicks say button1 (which is stop quiz) an input box will appear asking the user to input their name and then press okay. It then gets the current score from the text box (which is just an integer in a text box indicating how many they got right) and saves it to an Text file or something.and when the user goes back to the main menu, he/she can select "Hall of Fame" which then brings up the highscores (in a new form) of previous users scores.

View 2 RepliesI want to be able to create a custom shape that holds icons. Lets say for simplicity that it is a sqaure. I need the ability to load up to X amount of icons in the square. Lets say I need up to 6 icons. These icons will always be the same. However not all custom shapes will need them. I am assuming that I have to create a custom shape object class. I also want the icons to automatically adjust in size when I change the size of the shape. I am guessing that one way to do this would be to drop a TableLayoutPanel into the shape and then dock it to the shape. Then set the dock property of the icon to the cell that it resides into within the TableLayoutPanel in the shape. The number of rows/columns of the TableLayoutPanel would be predicated on the number of icons needed.
View 16 RepliesI've always had to use a program that does this stuff for me, but I'd like to just make my own program that does this. I've already got the individual bitmap images of the 3 sizes (16x16, 32x32 and 48x48) for the icon file and I usually find use some shareware program to create the icon file from the multiple bitmap images for me but I'm wondering if it's possible in .Net to create an icon file (*.ico) that contains multiple physical icons in it.
View 12 RepliesI'm using the following code to create a bitmap from a webbrowsercontrol that is located just off-screen (not visible to user, but control is "visible") Does the CopyFromScreen method work for something that is not ACTUALLY displayed on the screen?
I checked the values of p.X and p.Y at runtime and they are correct, but my "img" does not reflect the portion of the "Screen" i'm trying to capture.
Not sure what I'm doing wrong here, or if CopyFromScreen will still work if my control is outside of the bounds of the primaryscreen.

'This is set at FormShown time

I'm trying to create an image for printing and I know what the dimensions of the image (Bitmap object) is supposed to be in Inches but the Bitmap uses pixels so how would I define it's size to the number of pixels per inch?I do know what the printer's DPI is too, I'm able to get the horizontal DPI and the vertical DPI (which is 99.99% of the time always the same)
View 8 RepliesI've been reading a bunch of tutorials on Drawing in VB.Net, and still am reading them, but I have a question which I know I'll need to ask sooner or later:
How can I create a 4000x4000 size bitmap, and then draw a pixel at a certain coordinate on a bitmap? Like say I want to draw a BLUE pixel at coordinate X = 3000 Y = 3450. How could I do that?
how can i create an icon (with transparency) from a bitmap?
i've tried this code, which i converted from a create cursor function which worked ok with transparency. i'm guessing its the IconInfo hbmMask + hbmColor properties?

I want to know how I could create a bitmap from scratch with no images to start with.(I would say need. but than you would think this was for some sort of school project and it's not.)Basically, what I have is an image which is perfectly square in shape and has a black border with a black x going through it, what is not black is white. What I'm looking to know is how to take that small image (50x50 pixels) and make an image based upon those by placing them in X Rows of X amount. I'll make a couple example to show what I mean.(X's represent the 50x50 image.

The first step will be reading the data, so I created some VB codes:
Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.Filter = "Text Files (*.txt)|*.txt"
openFileDialog1.Title = "Select a text File"
' Show the Dialog.
' If the user clicked OK in the dialog and ' an image file was selected, open it.
If openFileDialog1.ShowDialog() = DialogResult.OK Then
' Open file.

The second step will be converting the data to some data format which can be used in a bitmap image. This part is making me confused. Some codes I made is listed below:

Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:
"MissingMemeberException was unhandled.
No default member was found for type 'bitmap"
I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.
