Zoom Into an Image

[jayadevu]

Hi,

is there a way to Zoom into an Image. Much like Irfan View or Windows Photos. Any example available ?

Warm regards,

To control graphics, it is best Bos-Taurus. The help is very well detailed

Yes. That is right.

You have to use particularly this function.

Code: Select all

BT_BitmapCopyAndResize (hBitmap, New_Width, New_Height, Mode_Stretch, Algorithm)

Copy and resizes the specified bitmap and returns a handle to the bitmap with the new size.

hBitmap: is a handle to the origin bitmap.

New_Width, New_Height: is the new size of the bitmap image.

Mode_Stretch: sets the mode as the bitmap of origin is adjusts (is stretches or compresses) in the new size bitmap, it is one of the constants: BT_SCALE or BT_STRETCH (defined in BosTaurus.CH). For default Mode_Stretch = BT_STRETCH.

Algorithm: sets the mode as the bitmap is resized, it is one of the constants: BT_RESIZE_COLORONCOLOR, BT_RESIZE_HALFTONE or BT_RESIZE_BILINEAR (defined in BosTaurus.CH). For default Algorithm = BT_RESIZE_HALFTONE.

Thanks ndarz and Rathinagiri.

Where is the documentation of BosTaurus ?, I am not able to find it in hmg.3.4.0

Warm regards,
