Difference Between Saving JPG Images As JPEG Or EXIF
Sep 25, 2009
I have many jpg images from a camera, I add a description using exifworks to modify exif data. What is the difference between saving as format.jpeg or format.exif. I had been saving as jpeg with no differences noted but which is correct & why?
I'm having a problem with displaying JPEG images in a RichTextBox. When I insert a JPEG image into a RTB it automatically gets converted to a wmetafile8 and displays correctly - however, if i insert a JPEG image into file via another method (currently using the web) it get saved as a jpegblip (as you would expect) but the RTB will not display it. Opening the rtf document in Word displays the image correctly.I have tried this with png and gif files also but none of the images will display unless they are wmetafiles. Is this a limitation with the RichTextBox or is there another reason?
i made a class library with by adding two .jpeg images and changing build action property to embeded resources and i saved i want to use this two images from this .dll into my application .
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.
Right now the existing VB code I have uses GUID to generate "random" filenames on save. For instance: ff8514d389a041649fd8b925a32f2b51.jpg e1c938560fc1464ab2138065fc4661d3.jpg
Instead I want a date stamp, Time Stamp, and numbered filename: For instance: 20091015_131644_001.jpg <--(Date_Time_NumberIncrement) 20091015_131551_002.jpg
Or something along those lines. The current code (which saves a jpeg to a random GUID filename) is below: Imports System.Web Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.IO [Code] .....
I am allowing users of the admin panel of my website to upload photos, its a simple process where I check the validity of the image and then save it to a folder, then I also have to record a couple of database records for that image to be able to retrieve it later, my saving function is as follows...The function that uploads and saves the picture in the folder with a name i construct in another function: [code] and the function that creates the database record for that same picture: [code] Now I know that what I am doing is full of best-practices violations, so please point me out to what I should do, keep in mind that the users might delete the pictures later, so I wanna make sure that I can delete the database and file of the picture, and the whole issue of the path.
I have been looking all over the internet for the answer to this question: How do you save an Image (actually a Bitmap) to an ImageList at runtime? I have an extremely simple image editor that I created to make the images I require for another program. I have incorporated the image editor into the other program. However I cannot figure out how to save user-created images in the ImageList I am displaying via ListView. If I am aimed in the right direction, I can usually find my way through the maze.Additionally, I may need to know how to select that image (I may be able to figure this out later).
Saving an Image to An SQL Database from a Visual Basic ASPNET.rtf?written in Visual Studio 2008, which is supposed to Insert Images into an SQL Database in Visual Basic ASP.NET I know it contains some errors but I can't point out exactly where I got it wrong?
I am attempting to save a graph that I have displayed on the screen as an image file (e.g., a jpeg file) but the image I want to save has additional information such as axis labels that are not displayed on the screen. In addition, I also want to suppress some information that appears on the screen.
I create a separate bitmap canvas called mycanvas and I recreate my display on this canvas with the additional information. When I save it with an image format such as iftype=system.drawing.imaging.imageformat.tif with the command mycanvas.save(filename,iftype), I get the image file that I created on mycanvas. But If I use the SaveFileDialog followed by mycanvas.save(filename,iftype) I merely save the image displayed on the screen. It is as if my graphics object has reverted back to the graphics object I was using for the screen display.
This is a newbie question. I am trying to create an applicatiojn which allows the user to enter info on plants including photos. I have set up the database using image datatype and created the form using the dataset but when I save the data everything is saved but the image file. Obviously I need extra code but I can't find anything in the help files etc that shows me. This is the code I have at the moment
I am currently working on saving some info and images. And i was looking at a game maker i used to use and it saved images as a "1rc" format. Is this custom? And can i save and load images as a "1rc" format?
I want to load images into a picturebox, save them into a database and display them again in the picturebox. This is the code I'm actually having problem with:
Private Connection As String = _ "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:UsersclientDocumentsVisual Studio 2008ProjectsSavingsLoansCalc.mdb" rivate Sub UploadButton_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles UploadButton.Click [Code] .....
I'm getting this error message: "Type 'Connection' is not declared" On this line: oConn = New OleDb.OleDbConnection( _ New Connection().getConnectionString)
now the remaining things are done-able but im stuck in new requirement posted by Client which he needs to upload all images from Sql Server to Oracle Database now since old application stores images Path it is kind of new story now ?(:
i tried to build sample application since am not familiar with kind of above requested modification here is my code so far to upload images
'' Sql connection is over Dim fs as new fileStream (imgPath , io.fileMod.Open , Io.FileAccess.Read) Dim imgByte (fs.length -1 ) as byte
Ok you know how our web browsers like Internet Explorer or FireFox has the option to "Save Page As". Is there a way to do this using the Web Browser Control? I wish to save the HTML + Images that are displayed in my Web Browser Within my application. Or say if I go to a website and they have a dynamic image that keeps Changing is there a way to save that image that is displayed on the Web Browser control?
This is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.
Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.
Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?
I'm using the ExifTools code to read and update the EXIF for JPEGs in a VB.NET project I am developing. So far I've been successful with doing what I need to but I'm having difficulty with the last thing on my wishlist- the "Keywords" or "Tags" entry. The "Tags" property (as accessed by file right-click->properties->Details and just below the rating stars) is populated with information but if I use the PropertyItem for Keywords (Value 40094) with the ExifTools GetPropertyValue() function, it returns nothing.
It's pretty obvious that the "Tags" entry under file properties is not the same thing as what EXIF defines as "Keywords" but I have not been able to figure out what the correct PropertyItem value to pass is.
I am working on a project where I create image files from calculations done from user inputs. The work is saved as jpg images in various sized and I want to add EXIF data to the saved filed and later on retreive these data again so the user can continue working on the basis of a re-opened image file as I hope to store the project variables as metadata in the image file.
I'm looking to create a csv file of image_names, latitude, and longitude extracted from EXIF headers of several jpegs. I'm having trouble parsing the lat and long byte array items to decimal or ascii. Here is what I have so far.[code]...
