Im trying to rotate an image but it dosent work good enough:
Im using pictureBox1 and pictureBox2 and a button1
Im doing image cropped and then i can drag the image around the form with the pictureBox2.
Now i did that when i click on the button1 in the button1_Click event it will rotate the image by 25 degrees.
The problem is i want to rotate the original cropped Image and not a new one so this is what i did in the rotation function:
...Code:private Bitmap

Nothing. It dosent draw anything and dosent give any error.
Why ? Isnt it good ? The reason is cuz i needed this rectangle to mark a text in the center of the image to identify the text location. So it dosent realy matter for now from wich direction i draw the rectangle.
I guess ill add the top and left sometime.Leave a comment:

Since the drawing is all the time start from any point and go to the right or down only i dont need Top and Left.Code:(e.X > pictureBox1.Size.Width || e.Y > pictureBox1.Size.Height)
Anyway this is working.

The original idea is to rename the original files to new names. Keep the files same content just rename them. So maybe i dont need to create new bitmap files and all the stuff.
Since in string C i have the new file names how can i rename now the old files ? So if file number one was d:\......radar0 01.jpg so now it will be d:\......radar0 00001.jpg
