Asp.net - Save Image As Jpeg File Rather Than Aspx File?
Jul 8, 2011
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 need to get a jpeg image from file system, feed it to DrawImage method for resizing and then save the result to a varbinary(MAX) field in a SQL Server table. How can I do the conversion from file system to image (from DrawImage method) to the varbinary(MAX)
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'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)".
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 want to create a sort of slide show program. I want to get a folder full of images (bmp and jpeg file types) and have this program display it really quickly and then refresh to show another randome image really quickly. Then I want it to look into another folder and grab an image file from there that will be the last image and stays up. What I want to know is how will i go about getting the program to get the random image and then how will I get it to refresh instantly?
When i try to use this it gives error: txtSearch is not accesible? what am i doing wrong here? This is not complete code just a snippet. But i think it gives an idea what am i trying to do.
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 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 Need to Store bunch of Jpeg files from local file system to a column with image datatype in databse.Can any one please provide me some code to do it?

I have created a VB.net desktop based application for my staff image uploading. How I can upload my staff photo in a specified ftp folder using my application.
Im trying to get an image from clipboard and save it to a file (.bmp)
Here is my
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long) Private Const VK_SNAPSHOT = &H2C
[Code].....
Btw (For the first code)If I press the Button the first time and i paste it manually(ctrl+v) to the paint the printscreen image is appeared.Also If i debug the code it works perfectly and it produces the .bmp file.
So im thinking its a timing issue , so I put a sleep(3000) after the keybd_event(VK_SNAPSHOT, 0, 0, 0) command and it still doesnt work.
but i have this exception call System.UnauthorizedAccessException which access to the path i wanted to save is denied. however, if i just save the original pic using FUImage.SaveAs(physicalFolder & FUImage.FileName) it is able to work. i just want the pic to be resized and save it.
Now, if any user enters the year, and uses the browse button to select any photo, and then clicks submit, i want that particular photo to be uploaded and saved on the my file system ( where the code is present).
I am using Vb 2008 Express edition. I have created an image with line on the picturebox.Here is my
Private Sub PictureBox2_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox2.Paint Dim blackPen As New Pen(Color.Black, 2)
I need to create a function which accepts a single value of integer which specifies the width/height of the resulting image, which will only have a single black pixel in the upper left corner and the rest being transparent and saved as a gif file.
Code that opens image file this code works properly Private Sub MenuItem4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FromFile.Click PBDisplay.Visible = False If OpenFileDialog1.ShowDialog() = DialogResult.OK Then PBDisplay.SizeMode = PictureBoxSizeMode.AutoSize [Code] ......
This code is what I am using to save image after it is re sized, It will not save the new image, it saves the old image and the old size. I am using a picture box to import the image into, then I am resizing the picture box and the image. But when it is saved it reverts to the original image. Private Sub MenuItem6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click If SaveFileDialog1.ShowDialog = DialogResult.OK Then PBDisplay.Image.Save(SaveFileDialog1.FileName) End If End Sub

I am working on a PHP site at the moment that is having trouble reading that data to display the image, so I am attempting to not only save it to the DB, but also save it as a bitmap or other file type to the actual server.
How can I create an image file (not really picky on which file type) from the "arrImage()" data above?
