Hello
I try to use then TImageEnView component to create a big map with some ImageLayers added to the background.
The bacgkround layer is from bmp file 9449 x 3509 pixels size with 32 bits pixel.
When I load this layer in the "standalone" form without additonal layers procedures then zoom, scroll operations are very fast.
But when I have this layer in the with TImageLayers, TextLayers, PolyLineLayers converted to ImageLayer all is very slow.
Can you suggest what shall I change or avoid to fix this problem?
Another question for me is how to remember the positon of the ImageEnView scrollbars when I finish/start/update the window. Now I always lose the position of the edited added layer - the window positons on the left top of the ImageView in the left top of my window.
kindly regards Stan |
