I've plot a histogram in a picturebox called picHisto, but i'm having a problem in save it to jpeg or other format. When it saved, it appears to be a blank or white picture. The code below is the code i used for saving, thanks for the help.

Dim g As Graphics = Graphics.FromImage(img)
I need to save the contents of a picbox to a jpeg file.I suspect the error exists because I do not actually load an image, but draw lines on its using picbox1.addline(), but I do not know how to fix this.

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?
how to save a jpeg image to the database. I am using fileopendialog to upload the image to the picturebox. This works fine but I now need to save this image back to the database. I am using an Oracle database (11g) and the image datatype is declared as a blob.

I created a paint type program for signatures, and now I would like to save my canvas as either a jpeg, bitmap, or gif file, but I am unsure how to go about this. Here is my code,[CODE...]
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.
I am trying to create a wpf program that allows the user to create custom shapes or pick premade shapes and that after making their selection, a canvas shows their shapes randomly sized, positioned, colored and copied in multiples. I am hoping that on click, the program will put its output on a time interval and that the user can click stop when they are satisfied with how everything looks. My issue is, I would like to also give the user an option to save their created artwork as a jpeg file. Also if I wanted to link this file to a web browser what will I have to do?
I have this program that is suppose to take the path I provide it and use it to save an image to my access database. But it keeps giving me ""Syntax error in Insert Into Statement." error message.
I am currently working on a program to graph a histogram of the Dow Jones, the following is my code
CODE:
Im not sure if my getdata() sub routine is correct. I want this to display a histogram of returns for the DJIA as well as display the mean and standard deviation.
Also, on my Convert(Y) function it keeps saying im diviging by zero but I dont see how I am.
I'm a programming enthusiast, and recently I am making a program that communicates with a webcam and captures an image. I copied the API call for avicap32.dll from some website and the program works just fine.
The images on my e-commerce website are watermarked with an aspx script, therefore when you are browsing products, if you want to save the image it saves it as aspx rather than jpg or png. The thing is I need to give urls of jpg for a website that advertises products. There are more than 10,000 products so I can't save all of them manually, so I made a page with jquery that get's the image part of the product display page. What this page returns is this:
And the output is only an image. How can I return this image not as an aspx page but as a jpg or png? Since there's a script for watermarking the image and making it aspx, shouldn't there be a reverse function?
I have the following code in my asp.net: <asp:Image ID="imgInv" runat="server" width="600px" /><br /> Then in my vb.net page,i have the code:imgInv.ImageUrl = .Item("ImagePath") The data that I retrieve from my sql server is such as:C:1.tif However, the image could not be display. May I know is it vb.net does not support to view tif format picture.
I just wanna ask, how to format an image or a picture inside an RTB control? Its like the way MSWORD does the formatting, (i.e Center, Behind Text, etc..).
