Low Quality Image Into A Label?
May 4, 2012
I'm trying to pass an image showing to the user a countdown. For this, I'm using a separate thread where I'm checking when the countdown timer should be started, and when so, I draw an image for every 6 seconds passed.
What's annoying is when I pass the drawn image to the UI, the quality of the image is changed and it looks bad to the user.
This is my little script that handles the drawings:
Try
remainingTime = (#12:04:00 AM# - (DateTime.Now - local_DateTimeclick)).ToString("HH:mm:ss")
remainingTimeInSeconds = Convert.ToDateTime(remainingTime).Minute * 60 +
[Code]....
Also tried with changing the properties of g, but there was no positive effect.
what can i do to make this properly work without changing the quality of the returned image?

I am trying to edit an image. I can open the image with Picturebox1.load(mypicture)
I can change the pixels/edit the picture by Dim img as new bitmap(picturebox1.image)
[Code]...
now here is the weird part. When I save the image the filesize INCREASES..but the picture dimensions are the same Example... TEST.PNG 1.3KB, when opened up via picturebox/saved the image is now 2.3KB
not sure why...i even though I specify system.drawing.imaging.imageformat.PNG
samething with JPG... it actually SHRINKS it evenmore.. example 88KB jpeg.. saved as jpeg is now 47.7KB...

I've developed an application that acquires images from my Logitech QuickCam Pro 9000 using WIA. The problem is that I cannot figure out how to adjust the quality of the image taken by the camera. The camera has a 2MP lense, but the program will only acquire a picture of 320x240 pixels, which is the lowest resolution the camera has. How do I tell the camera to take a picture at one of it's other resolutions? IE: 640x480, 960x720, 1.3MP, or 2MP?

I had this question before "Resize image on the fly make the image lose quality online but locally works nice".And what i got now is that it's not a problem of local or online, i ran this resize on the server itself "dedicated server", and i got the same bad quality image, so the problem is in the IIS configurations.What in iis can make this bad quality image happen?

I'm using iTextSharp to print a PDF document. Everything goes ok until I have to print the company logo in it. First I noticed that the logo had poor quality, but after testing with several images, I realize that was the iTextSharp rendering it poorly.The test I did to say this was to print the PDF using my code and then edit the document with Acrobat 8.0 and I drew an image. Then printed the two documents and saw the noticeable difference.My question is that if anyone know if this can be due to a scaling problem where I'm failing to tell iTextSharp how it must render the image or is an iTextSharp limitation.

I have a routine that creates a report which includes text and graphics. When I print to a PDF or printer the output looks great. When I draw the report on an image to save as a PNG, GIF, JPEG, etc. it does not look as good and I understand that is related to the 96 dpi native resolution. However, I made some modifications, and even though the graphics part of the image looks better, the text does not look as good as the PDF. I am creating the image using 300 dpi and text rendering is set at the highest quality.

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 have an owner-drawn control where performance is an issue during quick repaints such as object drags, resizing and painting the selector square. i have noticed that several other apps, including Picasa, will temporarily draw a reduced-quality image during fast repaint scenarios and then update the image with a higher-quality version when the UI "settles down."
How should I (can I?) produce a lower-quality image to paint when many quick redraws are taking place? Are there other strategies similar to this i can employ to increase performance (or fake increased performance.) [code]...

I have a panel on a form in which I have two labels and a small picturebox. The label texts and image in the picturebox are changed from time to time program matically. I would like to have where a user can click anywhere in the panel to bring up another form, but I have not been able to make it work. Since the labels are I guess "above" the panel, if the user clicks on the label itself, it does not trigger the panel onclick event.

I have a graphics application that uses graphics paths. Code seen below. You can use keyboard characters to display information. When a label is set to visible = false after being turned on for a number of seconds a stray image is generated. The stray images are also sometimes generated when the label is first made visible.
' points p10b, p2b etc are defined elsewhere
Dim GrpPoints As PointF() = {p10b, p2b, p3b, p11b, p5b, p6b, p12b}
GrPath = New GraphicsPath ' 7 path points
GrPath.AddBeziers(GrpPoints)
[code]....
I tried stopping the code from running when the label is set to visible = false but the stray image is still generated but just later. If you want more information let me know.The white arrows points to the stray image that is created just after a label that displayed information was set to visible = false

I need to know the best way to print a form in Visual Basic 2008. I have tried to print it using the printform method but the quality of the text is really bad. Are there other ways to print forms that dont involve the printform method and have great quality? I need to print the form the way it looks on the screen(which consists of textboxes,lines,labels).

Does the quality of code merged by TFS 2008 depend on the used programming language? I know merging in Java / Subversion, and merging a branch to its trunk usually does not create much conflicts. Now in my company, we use VB.NET. When I merge two files TFS does not always get code blocks right, e.g. does not find the right If..then / end if lines. To give you an example, I mean: File 2 is created as a branch of File 1. Both files were changed later, now I'm going to merge those files and am recieving conficts: The marked end-if lines (1) are detected as corresponding, meaning the added event handler Button1_Click is being deleted.
Now I wonder if this behavior is by language (C# vs. VB.NET) or are other source control solutions just better than TFS? (And I really liked TFS up to now :) )
File 1:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
[CODE]...............
File 2 (Branch of File 1):
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
fillTableFromDatabase()
End If // (1)

In Reporting Service, I need to have a vertical, starting at bottom, bottom-to-top, horizontally middle aligned text.The only way to do this is to create an image in code, and set this image into the title column.See the code below.Basically, it works fine, just that the anti-alias quality is pretty crappy.Is there anything I can do to improve it ?The vertical text is somehow pale, and not full black, and also there is smearing all around the text, in the background color.As well as it appears bolder than the text on the left, but both have format arial, size 8, bold I've tried all other values of System.Drawing.Text.TextRenderingHint.*, as well as no anti-alias at all but the current one seems to be the least crappy.I've also tried to change the image format, to no avail:
Function LoadImage2(ByVal sImageText As String, ByVal sImageTextMax As String) As System.Drawing.Image
sImageTextMax = sImageTextMax.PadRight(15)
Dim iFontSize As Integer = 8 '//Change this as needed

I am converting an application that connects to Quality Center via the OTA API from VB.net to C#. The application makes extensive use of recordsets, but I have not been able to get them to work in C#.pecifically, I have trouble casting Command and Recordset to the correct format for C#. Everything I have tried has failed.Following, is an VB.net example of the code that I need to convert.
Private Function GetRecSet(ByVal Qry As String, TD as TDConnection) As Recordset
Dim Com As Command = TD.Command
Com.CommandText = Qry

I'm not sure where should I post this as this is not really related to VB.NET but since I'm always here(in the VB.NET section) I'm gonna ask here.How do I make an icon that won't lose it's quality? I tried so many dimensions already. 32x32, 250x250, 16x16, 64x64.It will lose it quality on Desktop and taskbar. An icon like the IE's, Visual Studio's, Google Chrome's icons.. icons that doesn't lose quality.

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?
