Hi,

I'm a beginner in graphics programming. I have the following situation:
I have to show existing bitmap in the control on the form and then put one
or several transparent layers over it which will be used for drawing.
Which control to use to load the existing bitmap on o form? Will picture box
do?
Do I need another control for layer/layers?

Thanks,

Jurica

You will be better off building a complete custom form for this job. The
functionality of the picure box control is inconsequential and you can easly
create a control that uses say, an array of images for layers.

Thank you for the quick response. I'm experimenting a little and I've realized
that picture box is a bad choice. Can you please tell me if you know some
kind of the image editing control that already exists, or where to start in
building it (use array of panel controls e.g.)

Thanks,

Jurica

Stay away from arrays of controls. Create a Control based object that can
display either a collection of images or uses a collection of custom objects
containing say, an image and an alpha setting.

Writing your own custom control (NOT a usercontrol) will be fare easier in
this case.

You may want to look at our MetaDraw control.
MetaDraw has a background layer and then allows
drawing on top of that ( drawing by end-user if you like,
or else drawing by code if that is better for you). While there are not
specific
layers on top - different graphics can be moved in front or behind other
graphics, and you can combine graphics into "groups" which you might think of
as
layers, and then move the groups in front or behind other groups. Also you
can
turn display of any graphics or groups on or off.
The result can be saved / reloaded, Printed, Zoomed, .....
