Hello All,

I am trying to convert an images BMP to an images GIF.
This works fine but I want to adjust de resolution from het GIF images.
Can I do this or is it not possibel? Does anyone have an example?

Bitmap mybmp = new Bitmap(strFileToConvert);

mybmp.Save(strFileToConvert + .gif",System.Drawing.Imaging.ImageFormat.Gif);

Image2.ImageUrl = strFileToConvert + ".gif";



Thanks,

Stefan

Do You want to resize bitmap (width/height) or something more
complicated? If true then do You want do resize "canvas" or
"scale" the bitmap?

To set resolution (dots per inch) you can call
Bitmap.SetResolution method.

Hello Marcin,



I am developing a application where the user can choose the size of the
image (width/height) and the kind of image they want to have (bmp, png, gif,
....).

The basic image where I start from is a BMP or a JPEG.



THANKS,

Only way to define Bitmap size is to set its constructor parameters e.g.:
new Bitmap(int width, int height, PixelFormat pixelFormat)

or creates an image copy with defined size:
new Bitmap(Image originalImage, Size newSize)

I hope its an expected solution. If You want some more... then
don't affraid to feedback.

Hello,

I can convert the images now and view them in paint and in de preview window
from microsoft windows xp, but I can't open the images(gif, jpeg, ...) in
fireworks and photoshop.
Does anybody know what I do wrong?

Bitmap bmpHulp = new Bitmap(strFileToConvert);

Bitmap mybmp = new Bitmap(bmpHulp,bmpSiz);


mybmp.SetResolution(intResX,intResY);

mybmp.Save(newFileName);

Thanks,

Stefan
