Hello guys,
I'm very new to MMF2 and trying to develop some kind of a Paint / Drawing software.

I have a few questions, and I guess I will have more questions related to this.
I hope that you guys will be able to help me.

Exporting to File:
- I put few active objects on the frame, no code yet no nothing.
I also made a button, I want this button to CAPTURE specific Area (for example 300x300)
and let me export what it see into image file (like you can save in drawing pictures).

Is it possible ? if it is can you please guide me a step-by-step ?

Thanks ahead everybody
Have a wonderful day !

Try messing with the "screen capture object", and the "overlay redux"

You should be able to archive what you want most easily with the screen capture object, including the exporting part.

Thanks for the fast reply !

I'm trying the "screen capture object" first.
I tried this:

- When Button clicked > Capture Frame Area
- Set Filename from selector

When I tried to follow the: "Final name (leave empty to open a file selector at runtime)
and click the Button no file selector pops up, no nothing.
But I want the open fie selector, so I can type the file name only when I click the button (export button).

Update:
Now it works, But I wonder if I can go even further, like it will capture only the active objects without background and export it as ALPHA ? (maybe PNG fies ? or it only works with BMP without alpha ?)

I'm pretty sure that you can't keep the background transparent.
But in case you'd be making a animation app and don't want to erase the background of every frame manualy, you could make a script in an advanced picture editing software that would do it for you. It's still a problem with shaded image or rotation though.

Changing the color of the background to black then taking another screen shot, then comparing the difference between the frames could work. That is beyond my scope though. I believe you would need the overlay object.

Thank you both,

It sound very complicated for me.
I did try to mess around with the overlay object but that confused me.

Is there any chance for somebody to upload an example source or step-by-step tutorial please ? it sounds like a very good feature and I would love to add it.

Thanks ahead everybody

Well, if anyone here knows how to decrypt a .png file's gibberish " tIME76" type of data, you could use the Mid$() function to replace the colour of your choice by the alpha-of-zero value(whatever it is) dirrectly to the saved file.
