Jun 1, 2010I know that you can pass a Point array to the DrawImage method of the Graphics object to apply rotation, skewing and flipping, but I'm having trouble figuring out how to calculate the rotation. So far I've got:
Dim radius As Integer = Math.Sqrt((rect.Width / 2) ^ 2 + (rect.Height / 2) ^ 2)
Dim dX As Integer = RadToDeg(Math.Cos(DegToRad(angle))) * radius
Dim dY As Integer = RadToDeg(Math.Tan(DegToRad(angle))) * dX
Dim new_upper_left_corner As New Point(rect.X + (rect.Width 2) - dX, rect.Y + (rect.Height 2) - dY)
This is all just off the top of my head so far, I'm not sure if it's right. How do I calculate the other points on the rectangle, and is there a built-in VB.NET method that's much easier? (Apart from Graphics.RotateTransform, which is slow and also rotates around 0,0.)

View 11 Replies[VB2005] Rotateflip Image Is Eating More Memory Than Non Rotated Image ?
Sep 8, 2009 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

View 10 RepliesTransparent Rotated Image Shows Original
Aug 15, 2010I have a image with a transparent background. I clone it, rotate it, and save it in a picture box. Works fine (in that I can see the original object overlaid on the background image below it). However, the original unrotated image is also superimposed on the .image layer *with* the rotated one. Try as I can, I can't stop it from appearing.
Curiously enough, if I change the image to non-transparent (a .bmp instead of a .gif, for example), I don't have the problem. Of course, I also can't see the background {:<(

View 5 RepliesCopy An Image's Region To Another?
Jan 25, 2011Following my test project for making a map editor, I finally got the tile selection part covered.The application can already tell which tile(s) is selected.
So now we will work on "click the map and the tiles will be drawn" part.
When the user clicks the map, I need to "copy" a selected tiles in the tile selector, and "paste" them on the map. The process is a bit longer actually.Or is there a way to directly copy the selected tiles to the map image?
Getting A Region Object From An Image?
Feb 2, 2010i have an image which has 2 colors, black and white.
i wish to get a region object that has all the white areas 'selected'
the shape is not just a polygon, its fairly shapeless
is this the best approach: create a region that is the size of the image and run a loop checking each individual pixel to see if its black, if it is then exclude it from the region. (i've got a feeling this will take very long to load)
