View 8 RepliesI am trying to convert from a text file to an image(bitmap) file.
For example, test.txt: 01 23 34 56 78 90

The first step will be reading the data, so I created some VB codes:
Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.Filter = "Text Files (*.txt)|*.txt"
openFileDialog1.Title = "Select a text File"
' Show the Dialog.
' If the user clicked OK in the dialog and ' an image file was selected, open it.
If openFileDialog1.ShowDialog() = DialogResult.OK Then
' Open file.

The second step will be converting the data to some data format which can be used in a bitmap image. This part is making me confused. Some codes I made is listed below:

I'm currently building an intranet engine for a project I've got on the go at the moment,and I'd like to save myself a little time by generating header images from code where possible, however, I'd like it to match our concept image.What I'd like to achieve is below:My issue is I've not the faintest how to create that from code. I can do the absolute basics but that's about it.I start to fall down when it comes to the gradient background and the drop shadow on the text. I can get away with positioning the text on the larger header image, so if it's not possible to generate the exact gradient I have there, then I have a work around for that, but what I really want to achieve is the text with the font and drop shadow.

Is there a way to read an image pixle by pixle and create a text file based in the information.Lets assume we are reading each pixle from left to right. Once you reach the last pixle of the line you move to the line below that one and continue reading.Here is a very simple "if" statement to help visualize the process:

i have an assignemnt in my visual basic express 2008 class, were i have to type in an image name, like paris.jpeg,and automatically manipulate the file to be called paris-steg.png. Once this happens i click the manipulate image button and the image should be altered so that paris-steg.png has a message hidden in it. Then i have to decode that message. At this point im having troubel getting the file name to automatically appear as paris-steg.jpeg, and you will proabbly see why with my code. I need to know how to do this. The way i have it, i basiaclly add -steg.png onto the text typed into the text box, this doesnt work when the user types in paris.jpeg as it comes out as paris.jpeg-steg.png. heres the instructiosn and my code

In this program you should read text from a file one character at a time instead of one line at a time. If <tt>sr</tt> is an IO.StreamReader, then <tt>sr.Read()</tt> will return an integer that is the value of the next character in the file. Use <tt>Read</tt> instead of <tt>ReadLine</tt> in this program.You can check whether a file exists by using the code <tt>IO.File.Exists(filename )</tt> . The function will return a Boolean value (True if the file exists but False if not).
You can check whether a string ends with a specified pattern by using the <tt>EndsWidth(pattern )</tt> function. For example, if <tt>s</tt> is a String, then <tt>s.EndsWidth(".txt")</tt> will return a Boolean value (True if <tt>s</tt> ends with the pattern but False otherwise).In a string, <tt>IndexOf(pattern )</tt> gives the first position where the pattern exists, but <tt>LastIndexOf</tt> gives the very last position where the pattern exists.The code <tt>s = Chr(i)</tt> converts the Integer <tt>i</tt> into a character and assigns the character to the string <tt>s</tt> .

View 1 RepliesI'm using this snippet to create a blank image in a picturebox, but is it possible to have the image coloured so that I can see it. (I'll need to colour it later anyway).
.Image = New Bitmap(newPictureBox.Width, newPictureBox.Height) 'blank image.
Also if it is possible, I intend to draw lines, rectangles on the image (hopefully) and save the lot, so would I lose the colour, or would it get saved, or does it depend on what it gets saved as?

View 3 RepliesI am creating an application where when I click on an image I need to mark the place using the x and y co-ordinates given by the click and then after marking I put a red dot/circle on that spot and then I need to save this image to a file including the dot/circle I marked. I have tried saving the image to the file but to no avail, I have been able to only save the PictureBox image and that doesn't include the graphics. It is only the base image. I have tried to save it as a bitmap but have not gotten anywhere with that either. It seems whenever I call the image.save it takes only the value of the underlying image and saves it.

I am building a program which offers solutions to the travelling salesman problem (finding shortest tour between a set of cities while visiting each only once).
My program loads a bitmap image of a map into a picture box. From there, graphics which point out the cities as well as tour paths are drawn onto the map. My problem is that when the option to plot ALL cities is enacted, the user may choose to pinpoint a specific city with a separate control. When the user erases that pinpoint via an invalidation routine, though, it erases all graphics beneath it, which is undesirable. How can I make my tour graphics and city plots semi-permanent by drawing them directly on the image? I tried drawing them on a separate bitmap, but it 'covered up' the map image.
i am wondering how to create a work area that i can store images that i have saved or scanned in my program. and i would like a page number folder aswell so you can see how many pages are in each folder when you choose the folder. so i know what i want it to look like, i will have two group boxes one called work area, and the other called pages. so when i click the work area folder called mike, it will show that mike has 59 pages in his folder and i can scroll and click each page(number) to view it in my picturebox. i would like to be able to create as many work areas as possible. i just need to know how to get started
