I have an app that needs to bulk rortate a folder of images either left or right using
rotate90flipnone or rotate270flipnone
The app does in fact rotate the images but when viewed as thumbnails in explorer they are not rotated. So my app needs to rotate the thumbnail as well.
I can get the image to rotate the problem is that on every step throught the loop the image goes to it inverse or draw backwards.

I have an application that downloads a .jpg snapshot from an IP camera, writes it to the server hard drive, attaches it to an email and sends it out to my users. Pretty simple until one guy had to mount his camera upside down and that's how he received the image via email.
It gets a bit annoying after a while, so he asked me if I could rotate it 180 degrees before attaching it to the email. I have absolutely no idea - hence my post. The app is on a hosted ASP.Net v3.5 web server.
I wish to import an image such as a wheel and rotate it about a pivot point continuously once a button as been activated. Would some kind person wish to share a code snippet in order for this to be achieved?

View 3 RepliesI have made a program that has an image moving across the screen. The image changes its movement direction when the arrows are pressed.

It uses the hidden PictureBox2's image (the original right arrow) as the source, because I couldn't think of any other way.

Im looking for an image viewer that supports most types of image formats, including PDFs, and has the ability to rotate/zoom, and draw on an image. I've been looking but to no avail. Does anyone have any suggestions on the best way of going about modifying a control so that I would have these features? The main problem that I am running into is the lack of the ability to draw on an image. Im still sort of a newbie to .NET,

In a game i am making, as the mouse cursor i have crosshairs (like those in FPS games) and i would like an image box to change images as the mouse moves so that it appears that the character in the picturebox is following the mouse cursor.
i thought i would do something along the lines of first finding out which side of the picture box its on (left or right) then finding out exactly where with some maths equations and then assigning 1 of 60 pictures so that it appears that the picture is rotating.
This code resizes a jpeg image, but instead of saving it I simply want to display the result in a picturebox. I moused over the the image box and the value thumb and they seem to be different formats. How can i convert bitmap to image?
View 3 RepliesI need to read a bitmap generated with paint or similar programs and interpert the picture to detect straight lines of black, larger squares in red and smaller squares of yellow, green or red. Which one of the Visual Basic environments are is best suited for this? WPF or Forms or..The lines represent walls and for start we have square objects as obsticles. I would like to create a maze and allow a dot to travel between obstacles leaving a trace of pixels and not hit any of the objects untill it exits.
I like to write the logic for it but I do not know how would I read a 500x500 pixel picture and decode the colors of each pixel. I like to assign a byte for each pixel's color (256color) but only use 4 bits of it to for start.
I am doing this as hobby. So please forgive me because I should only look at your answers during my free times.It will take some time before I could see it and mark your work as Helpful or Answer.

I am using this, however I get a GDI+ Unhandled Error.
Back when I used to use an 8 bit home computer I dabbled in machine code with an old version of BASIC which allowed you to POKE values into memory and then call the 1st memory location to execute that code. I used the equivalent HEX values for the processor which ran a series of ROR ( ROtate Right ) or ROL ( ROtate Left )commands through the carry bit as each line of the bitmap consisted of a series of bytes which were an 8 bit BYTE followed by the next BYTE in memory. The effects that I manage to create "in assembly language" as it were:
Scroll leftScroll right By manipulating full bytes in memory I created routines to:Flip the image horizontallyFlip the image verticallyTurn the image upside down Anyway, if you were to try this with the BASIC equivalent to GET and SET pixels, obviously the BASIC was a LOT slower. I am also interested in creating animated bitmaps from one or two images such as the following:Page turn effect.Sliding-in of an image in any direction.Ripple effect.Scratch effect.
