Remarks

You can construct Image objects from the following file types:

• Raster (bitmap) formats - .bmp, .gif, .jpg, .png, .tiff, and .exif

• Vector formats - .emf and .wmf

If you want to work with several images at the same time, use the Imagelist class.

You can construct the Image objects from the following file types:

• Raster, which is a bitmap, formats - .bmp, .gif, .jpg, .png, .tiff, and .exif

• Vector formats - .emf and .wmf

Examples

The following example prints the height of Picture.jpg in pixels.

Image img = new  Image(); 
  
img.loadFile(@'C:\MyPictures\Picture.jpg'); 
print img.height(); 
pause;
