Save modified DXImageList items

[floken]

Hi,

When I draw something in a DXImageList item, and then save the list to a file it don't save it with the changes... for example:

[pascal]
// Open a list
DXImageList.Items.LoadFromFile('mylist1.dxg');

// Drawing something to the first image
AnotherList.Items[0].DrawAlpha(DXImageList.Items[0].PatternSurfaces[0],Bounds(0,0,100,100),0,64);

// And finally save the list
DXImageList.Items.SaveToFile('mylist2.dxg');
[/pascal]


The mylist2.dxg remains equal to mylist1.dxg, it don't save the changes...

Please anybody could help me with it?

Thanx in advance.

Regards,
Floken

Please can anyone help me with this?

I made a program to create animated sprites, it fully works, but it can't save the changes

Why the modified items (after drawing in them) in the DXImageList don't save right?

I'm using PatternSurface to draw into the image, is that the problem? How I can draw to it in other way?

Too many questions, looking for little simple answer

Thanx, hope anybody could help me.

I believe you have to use assign, but I'm not quite sure how.
Not much of a help, I know, sorry ops:

An other idea perhaps is to save each frame to a seperate file and load them in the imagelist manually

[floken]

I've tried to save separated items but withou success...

I think the problem is when you draw to a PatternSurface (any surface?) in the item it don't make it permanent... don't know how to explain, but after drawing if I call the method Restore it back to the original image. What I need is the opposite of Restore, something like "FixChanges" or whatever.

I've tried several "assigns" methods but without success too

Thx anyway

Please anybody could help me? The program is almost done, without saving

Send your program to me and I'll have a look. Zip the source and send it to william@iafrica.com

[floken]

I've send you an example of the code I'm using, hope you could help.

Everyone who wants to try it, I've made it available at http://www.floken.com/tmp/Example.zip

Instructions:

first run the executable...

1. Draw something with the mouse.

2. Click the save button to save DXImageList2.Items to a file named "test.dxg"

3. Click the "New" button, so it clears the DXImageList2 contents...

4. Then, click the "Open" button to load "test.dxg" into DXImageList2


The problem is it don't save to the file the drawings made with the mouse.

Hope you could help, thanx a lot !!

Note: english is not my native language, hope you understand what I mean

I can simulate exactly your problem. I think it may have something to do with locking/unlocking the surface but I havn't got it right yet.

Also it could be that a picturecollectionitem only has a pattern surface on which to draw instead of on the actual surface.

I'm still trying to find a solution

[floken]

Thank you very much for trying, hope you could find a solution... I spent lots of hours with this project, but it will be useless without saving...

I've made it before using GR32 components, but I really want to use DelphiX because DX is a lot faster.

Thanx again, I'll be waiting and hoping you don't give up

Best Regards,

I havn't had another chance to look at this yet

I can think of a tenmporary solution but it may not quite be what you are looking for. Save the image to a bitmap (there is a thread from me in the DelphiX section on screen dumps that will show you how) - then load it back into the DXImageList.

I will still look into this sometime but I just dont have time at the moment

[floken]

Well, probably I'll use that method temporarly, but it's not appropriate using it in the final project.

Anyway, thanks for trying to help me with this issue.
