Convert To An Image File?
May 22, 2009
I'm studying for a memorization-intensive exam, and have lots and lots of lists to memorize. I have a Sony Walkman that can show *.JPG files and I had an idea. I want to create some video flashcards so I can study anywhere/any time. The idea is simple: I have some text that I want to convert to an image file. No, this isn't homework for a class. My experience to date has been 100% Excel/Access/Word related, so I'm completely out of my realm when it comes to images.

The coding below is to retrieve the Raw Image Data from the Database and then write as a JPG image file. The problem is the image file (image.jpg) is "nothing" after file created. I guess there is something wrong in the following coding.
fs.Write(rawData, 0, fileSize)
No any runtime errors I can find, and I double check rawData (i.e. Buffer) contains data. But don't know why there is "nothing" inside the image (image.jpg).
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim fileSize As Integer
Dim rawData() As Byte

Im busy making a program but it needs to send an image over a connection. Anyways, it is only possible to sends pieces of strings at the moment. And therefore I want to convert the images I want to send into strings or whatever that can be written in a textbox.Ive been trying stuff with streamreader / write but that didnt work so far.

Is there anyway to convert an image file bytes array into an array of the real RGB values of that image?
I don't really want to use GDI+ or the System.Drawing library, but simply apply a certain calculation/processing to every byte of the image file and get another array that contains the RGB values of every pixel in that image. I know it could be done as I know how to do it in a different programming language (Python) but not in Visual Basic.

How do you convert a System.Drawing.Bitmap image to any other type of image? I tried CType, which failed, since I do not know the type for .png or .jpg. I cannot find it anywhere on google either.What is the most efficient method to do this, which keeps the quality of the image as high as possible?

I have created in Visual Studio 2008 a Form with two buttons, a PictureBox and a TextBox. I've made the first button to load an image from my hard disk and I want to make the second button to convert the image into binary code and show the string in the TextBox. Image format is Jpeg. Here's the code for the first button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click PictureBox1.Image = Image.FromFile("D:\Pa.Pei\Pa.Pei. - Ergasies\4o Έτος\Ανάλυση Εικόνας\011.jpg")

I want to convert an image to a string, then put it into 1 cell in a datagridview as a string. I've read around on the forums and I saw some people say to use StreamReader, others say BinaryReader. Well Imma try both and see how it comes out. But I'm kinda stump. I'm trying StreamReader first, and I don't know how I should even do this. This is what I've got:
Dim ofd As OpenFileDialog = OpenFileDialog1
ofd.FileName = ""
ofd.Multiselect = False
[Code]....
In my do loop, should I put it into a temp text file and then read that textfile into the datagridview? If I did that, I think it would take up some time.

I have found that an image can be stored as some string. To give an example I have included a ms word part that has an image.I saved a word file with image and saved it as xml format .when i opened the xml file in a notepad i got following section. It must be the image being stored as some stream of text. Is there a similar way to do it in .net.

I am trying to convert a TIFF image to a base 64 string.I have seen so much code on the internet like the one below, but I don't understand it .I dont know what to change so it converts my image(s).I want the outcome (the bytes) as a variable that I can use outside this function. Know how to do that?

converting an image file into binary text in VB 2010.I am working on a compression program and need to see the actual binary as text. I have code for converting text files to binary and it works fine but, need to attempt files with greater randomness that are typically uncompressable.(JPG's) I understand that the file conversions may be huge. I plan on manipulating the binary in smaller manageable chunks.
