Image Quality Lost When Saving An Image In JPEG Using Bitmap?

Dec 28, 2010

'm working on an Image Encrypting software which reads out all the pixels of an image and then relocating the pixels in some way.

My Code is as below

Dim Img As New Bitmap(tbEpath.Text)
Dim ImgSize As Integer = Img.Width * Img.Height
Dim Pixels(Img.Width, Img.Height) As Color



Drawstring Text Quality - Image To Save As A PNG - GIF - JPEG

Oct 30, 2009

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.

When Creating An Bitmap Image From Scratch, The Quality Stinks?

Mar 19, 2010

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))

VS 2008 Open Image + Save Image + Keep Quality?

Oct 3, 2011

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)


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...

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:

remainingTime = (#12:04:00 AM# - (DateTime.Now - local_DateTimeclick)).ToString("HH:mm:ss")
remainingTimeInSeconds = Convert.ToDateTime(remainingTime).Minute * 60 +


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?

Adjusting Image Quality With WIA In VB 2005?

Jan 10, 2009

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?

ITextSharp Renders Image With Poor Quality In PDF?

Mar 26, 2010

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 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?

Mimic Picasa's Rendering Of Reduced Quality Image To Speed Up Drawing?

Jun 23, 2010

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]...

Read A JPEG File For Image Dimensions?

Mar 25, 2009

I'm reading a folder to assess the width x height of jpeg's, to classify them in various ways. Opening each as a bitmap and reading the bitmap width and height works but of course is laborious and very slow .... I've read various JPEG file format papers but retrieving the image pixel width and height seems none too obvious. Is there a logical way in VB to get this info quickly? My jpeg's are bog-standard ones made using VB's "Bmap.Save(Fname, ImageFormat.Jpeg)".

16 Color Bitmap Image And Interpert?

Apr 2, 2010

I need to read a bitmap generated with paint or similar programs and interpert the picture to detect straight lines of black, larger squares in red and smaller squares of yellow, green or red. Which one of the Visual Basic environments are is best suited for this? WPF or Forms or..The lines represent walls and for start we have square objects as obsticles. I would like to create a maze and allow a dot to travel between obstacles leaving a trace of pixels and not hit any of the objects untill it exits.

I like to write the logic for it but I do not know how would I read a 500x500 pixel picture and decode the colors of each pixel. I like to assign a byte for each pixel's color (256color) but only use 4 bits of it to for start.

I am doing this as hobby. So please forgive me because I should only look at your answers during my free times.It will take some time before I could see it and mark your work as Helpful or Answer.
