Export TkZinc Canvas as Image

Export TkZinc Canvas as Image

(OP)
In an application, We have big zinc canvas which have lot of items. Exporting them to image is taking lot of time, scrolling to each grid of item and capturing data


image create photo ${image}_tmp -format window -data $canvas

and passing it to main image

$image copy ${image}_tmp -to $image_x $image_y -from $border $border

tried making each grid bigger, but this will reduce the image quality.

Is there any option of exporting canvas as image more faster?

Tried searching on internet could not find anything.

Thanks in advance.
