display image larger than the screen size

[TheMrProgrammer]

i am using the drawimageunscaled from drawing a bitmap before showing the image i am setting the height and width of form = that of bitmap

height = b.height
width = b.width

but if the image is large, say, 3 megapixels then the size of form is limited to resolution of monitor what should i do?

Hi, if your system has only one screen, all forms are size-limited to the size of the screen. you can view (part of) a larger image, and optionally provide panning; one way would be by using a scrollable control. I could do that with a Panel; you might look at ScrollableControl too. AFAIK a PictureBox is too stupid a control to provide this functionality. :)

Not sure what you want exactly, however there are 4 overloads to DrawImageUnscaled, and 30 to DrawImage; there is bound to be one that can do what you want, remember you are allowed to give fractional and negative locations. BTW: when drawing onto a Bitmap, use Graphics.FromImage(). :)
