I need to rotate a picture box with about 35 degrees. now I tried this
PictureBox1.CreateGraphics.ResetTransform()
PictureBox1.CreateGraphics.TranslateTransform(64.0F, 64.0F)
PictureBox1.CreateGraphics.RotateTransform(35)
PictureBox1.CreateGraphics.DrawImage(sword, (-sword.Width 2), -sword.Height 2)
PictureBox1.Refresh()
But it doesn't seem to work Does someone know how to do this
I am trying to allow the user to rotate a jpeg and I know that you can do it pixel by pixel but WIA 2.0 is supposed to have that functionality built into it... When I try to set the filter, exactly like they do in the example.

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

View 1 Replies I'm writing a program that print images in full page. I.E, I print image on A4 paper, landscape. When I print an image without rotating it (the image IS landscape), the image uses all the space of the page, and is not cropped. it is OK. The print job is about 1.5 Mb. When I print an image WITH rotating it (the image IS PORTRAIT ), the image uses all the space of the page, and is not cropped. it is OK. The print job is about 28 Mb. The images are about 2000x3000 pixels, and stored in JPEG files (about 2.5 Mb each). I suppose that the 28 Mb should be the "uncompressed" size of the picture, and 1.5Mb, the compressed size...
By the way, When I look at the task manager, my application memory usage grows by job size, which seems to be OK. It grows either 1,5 Mb if no rotation is occured, and 25-30Mb when rotation occured.
Since I can print hundreds of image at once, my print queue will grow abnormaly if I need to rotate all
I'm creating a form which is basically an image in a picture box that I use the graphics object to do drawstring's and drawimage's upon.I keep track of where I'm drawing these things so that I can click on them later and do various things (launch external apps - whatever).Is using a picturebox and the graphics object the best way to approach this.
View 1 RepliesI have two methods in a class for placing and rotating an array of objects(Pieces) on a Board.pieces have a bounding rectangle and a property called center that is the center point of the rectangle(piece).what i want is to rotate all the pieces in clockwise or counterclockwise direction ,depending on the mouse direction,when the mousebutton is down on any of the pieces other than the center piece and the mouse moves.can anyone modify my code below to achieve this or post some new code that does this. using the rotatepiece() method below in a timerevent with a buttondown event to start the timerrotates all the pieces in clockwise or counterclockwise direction.

View 14 RepliesSo far:
PictureBox1.Image.RotateFlip(RotateFlipType.Rotate90FlipNone)
but this only turns at 90, 180, and 270 degree angles, also allowing flipping, but isn't exactly what I am after. I am trying to make the picture spin randomly at a variety of angles, but even if I can only get 45 degrees is better than just having 90 degree ones.
However I have only been able to find the above example in my searches.
I am trying to solve the issue that I posted about in the game programming forum about the animated dice. It seems that this is a very difficult thing to achieve, so I am going at this in an obscure way. My idea behind this is to have a timer set the images in a picture box according to random counters (which I have working). Then I plan on making the image rotate along with the timer (which is where I am at now). Then I plan on having the picture box move across the screen along with the timer (bouncing off the sides)...I think that this might be a bit better when trying to achieve an "authentic rolling dice" without actually having to do everything in 3d.
I'd like to rotate only one of the shapes in an animation, but the rotatetransform method applies this rotation to the whole view. I have several shapes which I want to remain stationary, and just one that should be rotated. I've been trying to use containers but so far this hasn't helped. This is visual basic on XP, using .net gdi+, system.drawing. I'm using translatetransform to establish a rotation center.

View 1 RepliesI had an assignment that I had done, which has been turned in, I was able to get it to graph, but it when it reaches the right side of the screen it drops off, when it is is adjusted using the velleman controls it jumps back up, hw would I fix this.
Here are the instructon for the assignment:
Write a program tat rads two analog inputs from a velleman board and plots the values on a rotating graph. The number of value plotted horizontally should be specified in a text box. Label the graphs vertical values in at least three places. Print the current voltage reading for each input in it's own lable. The graph should auto scale to fille the graph vertically and horizontally.
The two things that I couldn't get to work is the graph drops off the chart and I was unable to place the vertical values in three places.
Here is my code:

I want to make a small logo in the upper corner of a Form rotate.
I've seen on some forums that they have small avatars dancing and such, so I imagine it would be posible to make a tiny image rotate by it self up in the corner in a Form.
Does anyone know how to do this? Link to tutorial, codesnippets etc..
Ps. The goal is to make it smooth. Not turn 4 x 90 degrees.

View 1 RepliesI'd like to be able to graphically represent a position in a 3D graph and be able to rotate the grid to match a certain perspective.

In VB2005 GDI+, it's not too difficult to get zooming and panning working together, or rotating and panning. But I am finding it very difficult to get all three functions working in coordinatioin. The code below is the nearest I have reached so far. It's a working example on a standard Windows Form, but please supply your own image. The user can drag the image with the left mouse button, and toggle wheel zooming or rotating by tapping the space bar. Both zooming and rotating work. But the stationary centre of zooming or rotating (marked by a red cross in the example) remains relative to the image.
View 1 RepliesI am trying to make a random shift scheduling application for a rotating workforce that must satisfy the following basic requirements: 3 shifts (8 hours each) per day (Morning, Afternoon, Night), 2 workers per shift work a maximum of 7 consecutive days and rest a minimum 1 day. 9 Total workers separate in 5 supervisors and 4 operators, and 2 part time workers (1 supervisor and 1 operator) for covering the possible absences of 9 standard workers. Total days off are 8 days per month (normal sequence 2,2,4) and the vacation days are 22 per year. A basic rule is that the shift must cover from 2 supervisors, or 1 supervisor and 1 operator. 2 operators are forbidden.
View 4 RepliesI need to overlap two images. When overlapped at the correct point, the overlapped portion of both images match exactly (or very closely).Now, I have tried to match the color of each pixel in the images, then move one image a bit and match them again until I get a high match rate, usually 95% or higher. The issue is, this is ridiculously slow. Also, I can't find a way to check the pixels if one I need to check a negative co-ordinate.

I have a picture viewer with listbox,listview,picturebox. I used code snipets and modified them for about 3 weeks now. It works pretty good too i think. But when i add images as thumbnails to my imagelist from openfiledialog i can only add about 75 images any more and i will get a out of memory error. Or if I add say like 50 twice the second 50 added will have the right names but not the right image. My question is. Is there a way to load some images pause then load some more by code for about 250 images so that the loading could clean some memory? And or code where i could add aditional images to the imagelist? And i just cant stop trying to get this Picture viewer to work right.
