VS 2008 Choppy Font Edges When Transfering Image From A Bitmap To A Graphics Object?
Jun 3, 2009
i am drawing a string to a graphics object in the eg below and then transfering it onto a e.graphics in the paint event of a panel... when doing this the font edges appear dodgey...
Here is some
Dim b As New Bitmap(100, 100)
Dim g As Graphics = Graphics.FromImage(b)
g.DrawString("Bla Bla Bla", New Font("Comic Sans MS", 18,FontStyle.Bold), New LinearGradientBrush(g.ClipBounds, Color.Red,
I tried to skin my application and failed. I can get it to work if I don�t have semi transparent pixels on the outside of my form. But I want to use a skin I found on Deviant art that was made for Miranda. It is really nice but and it has a shadow around it. To get it to work in vb.net (I�m using 2005 btw) I have to fill around the main picture and take out the initializing (I think that is what it is called). But then the form�s edges are choppy. How does Miranda allow the shadows but I can�t in vb.net?
I first tried to do it the easy way. I set up some transparent panels with transparent pictureboxes in them and put my corners and middle fills as the backgrounds. I made the form with no border and set the transparent key to transparent. That didn�t work, so I made the form magenta and the transparent key magenta. The outside of the for where the shadow is was drawn on the magenta and the magenta bled through. So I edited the png�s to be magenta all around the form (eliminating the shadows) and it worked, but the corners were choppy.
Then tried some code I found on the net that tried to make a new control as a transparent panel. It was overriding the paint events and drawing to an off screen bitmap. I really didn't understand it and it just showed up as a blank screen. There has to be a way to do this.
Pretty self-explanatory question. I'm trying to see if I can do sprite animation in Visual Basic and, while I can use a Graphics object to translate a bitmap down a few pixels, I have absolutely no idea how to erase the bitmap drawn in its former position. Is there any way to erase the old image before the new image is drawn onto the form?
What i'm trying to do is fill a non rectangular region (actual build up out of 6 points) and draw a bitmap in such a way that it stretches with the region. Now for drawing a normal bitmap or even a trapezoid bitmap there are examples on the net. but drawing anything more then that with GDI+..
How do I rotate a bitmap image that has been placed in a picturebox? I need to make it appear upside down or rotated according to user input. I can't find anything in the properties to do this
I know that you can pass a Point array to the DrawImage method of the Graphics object to apply rotation, skewing and flipping, but I'm having trouble figuring out how to calculate the rotation. So far I've got:
Dim radius As Integer = Math.Sqrt((rect.Width / 2) ^ 2 + (rect.Height / 2) ^ 2) Dim dX As Integer = RadToDeg(Math.Cos(DegToRad(angle))) * radius Dim dY As Integer = RadToDeg(Math.Tan(DegToRad(angle))) * dX Dim new_upper_left_corner As New Point(rect.X + (rect.Width 2) - dX, rect.Y + (rect.Height 2) - dY)
This is all just off the top of my head so far, I'm not sure if it's right. How do I calculate the other points on the rectangle, and is there a built-in VB.NET method that's much easier? (Apart from Graphics.RotateTransform, which is slow and also rotates around 0,0.)
I've been searching for days. I can't find anything that I think is going to work. I've probably read the answer and skipped it because I don't get it. I'm new. I've researched multithreading, sub routines and webbrowser. The webbrowser thing doesn't seem professional to me.
All I want is the animation to be smooth when it's displayed and to have it integrated into the app so it's not called from the local drive.The animated gif is in PictureBox3. Please point me in the right direction. I really don't want to use a static image.
I'm trying to do for a website. I've got a header banner that is 900px wide, and I want to display 4 random images across the banner. (I've got about 20 photos at this point, and I want the header to select from them.) I can get the code for the random selection, but what I'm looking for is a way to blend about 10 pixels near the overlap. If I have each picture exactly 225px wide, I get a "hard" line between the images. I'd like to make the images a little bit wider and soften the edge by overlapping and blending the images together. I have figured out how to get the image back to the web browser, but I don't even know where to start on trying to figure out the blending. Graphics really aren't my thing.
my goal is to copy the content of a picturebox, to a System.Drawing.Bitmap object, called tempBMP. but i didnt even use it i just tried to declare it there's an error: Object reference not set to an instance of an object.
here's my
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Dim colors(sizeX - 1, sizeY - 1) As Color
I have a scanned document in my system. It's a tiff file. You will see below the code i have written. The problem is that i get an error message. The message is like this "A Graphics object cannot be created from an image that has an indexed pixel format." [Code]
In VB.NET, I need to create an Image based on a Graphics object I have. However, there is no method such as Image.fromGraphics() etc. What should I do then?
I am attempting to create a class library that can either search a bitmap to determine whether or not it contains an exact match to a second bitmap or if it contains a partial match. Currently it only returns true if i search the image for itself or if the sensitivity is below around 15%, even when i search with an image that i know should return true. The images I am using are simply a screenshot saved in paint and a section of that first screenshot also saved in paint. Here is my current .dll coding for VB 2008 Express
I am trying to get a small bitmap from a larger image. something like
Dim bmp As New Bitmap(PictureBox2.Image)
However this just gets the entire picture not just a portion of it, I would like to do something like this where I can specify the starting and stoping points
Dim bmp As New Bitmap(PictureBox2.Image, StartX, StartY, EndX, EndY)
I would also like to take these smaller images and paste them into a single larger image. Is there any way to paste it in starting a a certain point. Such as
I need serious advice here please. I use Visual Basic Graphics Programming by Rod Stephens as a reference, and I have visited his site vb-helper.com to try some of his tutorials. I tried the scribble application and it's working out fine (you can download the snippet from his site).
What I have trouble with is zooming in. I am not sure where to start. I would like to zoom in to x2, x3 and etc. of the bitmap I am working on and I would like to be able to continue to edit the bitmap. This would mean that I have a larger pixel brush under the mouse cursor, to lay down pixels. So a x2 zoom would mean a 2 x 2 pixel.
Has someone done this. Do you have a reference I can use for this. This kind of editing is standard in almost every paint package. Even Microsoft Paint, but there is not too much basic information on how it fits together in code for vb .net. So I am looking for someone to point me in the right direction. As I said, I am using the scribble application as a base, so here is the link. [URL]..
I'm having an issue with some code I'm trying to write that takes a screenshot of the current screen and saves it to a bitmap file on my local PC.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim tempScreenshot = New Bitmap(Screen.PrimaryScreen.Bounds.Width,
I am trying to use DrawString to write text as an image and then rotate it 90 degrees. It works fine with both a bitmap or directly on a PictureBox, but the big difference is in the quality. The PictureBox text drawn has great quality and looks nice. When I draw it on an image it looks horrible and blocky. I've made a few changes to try and get it to look nicer, but it doesn't look nearly as nice as it should.
Sample code:Use a Windows Forms project and place 2 picture boxes on it and a button and run it with the following code to see what I mean:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
faster way to flood fill an area of a bitmap? It basically acts just like the fill flood bucket in MS Paint. clsBitmapImage is a Bitmap variable.
Code:
Code: Public Sub FloodFill(ByVal AtPoint As Point, ByVal newColor As Color) Dim oldColor As Color = clsBitmapImage.GetPixel(AtPoint.X, AtPoint.Y) If oldColor.ToArgb <> newColor.ToArgb Then
So, what I've got is a picturebox and a textbox, I got some code to put text into a picturebox so I could better understand how it works, but what I don't understand is how to put the text on top of the image that is in the picturebox, can anyone tell me how to do that? Here's the code
I want to transfer data from one rich text box to another but when i use RichTextbox2.text = RichTextbox1.text it transfer just text not images.if there is any way to do so?
In the below code I load the image to the graphics path using resource image and adding text on it. When I add the image through open file dialog it paints on the form with original size but I need to resize it, add it to the PictureBox, add text to it and give zoom and pan options to it and then I need to save with the original size.
When I resize and when save the image I endi up with a small image.
Here is my code:
Imports System.Collections.ObjectModel Imports System.Drawing.Drawing2D Public Class Form1
