@panoss: What happens if you replace by
  alpha := FMaskScanNext().red
?
Sorry, but the error message I mentioned, appeared in a windows xp machine in an internet cafe, and now I don't have access to it  :-[.
But I tried lazpaint in my pc, ubuntu 11.04, lazarus  v0-9.30-0, lazpaint4.4.1, bgrabitmap4.7.2 and it compiles!
But, the two small forms (Tools form and Colors form) are frozen! They don't work!

I have no idea why these forms would be frozen. What happens if you hide them and show them again using the View menu ?

I can confirm that problem, when I tested ubuntu some months ago.

I posted a new version on subversion with :

- ask to merge selection when saving
- load and save selection
- avoid crash when closing with selection
- rewriting of undo/redo
- undo/redo bug fix

If someone can debug ubuntu version, it would be great.

I've posted a compiled version 4.4.1 for linux (thanks to Daniel) :

Thanks.

You can add a feature to save .ico files? That's because IcoFx now is commercial  :(

It's not so easy to do because Icon can have multiple images.

Hey people, maybe i've found why the toolboxes were frozen. I was using ShowModal for main form. I've updated on subversion. Does it work on Linux now ?

Ok so here is last version LazPaint4.5 as zip and exe for Windows :
https://sourceforge.net/projects/lazpaint/files/bin/

It uses last version of BGRABitmap (4.8 )

I've asked Daniel for the Linux version.

You need to update the update checker website version.. I have the latest version 4.4.1 xD

Hi.

@benohb, yes but UPX means it will use more RAM to uncompress the binary at every start of lazpaint.
4.5 for such an application is NOTHING, look at Paint.Net for example, with the DLL i have 30MB after the installation... so LazPaint rocks :D

@circular and lainz, i updated the version number for the update checker. I also moved 4.4.1 and 4.4.2 files in the old directory.
I'm using Arch Linux.

Thanks benohb for the tip.

I would say the first reason why upx is not used, is that it is an extra step added in the creation of the executable and we are lazy (well in fact I don't even have Linux).

Fabien points out that it needs more memory. Well I do not agree, if it is just one instance, but if multiple instances of LazPaint are used, it may take more memory.

I've tested with 20 instances on Windows. Without compression of the exe, it takes 110 MB of RAM, and with compression, it takes 158 MB. The difference is not so big. Of course, on the disk, it takes less space, only 1.1 MB instead of 3.5 MB.

The design of LazPaint is to hold only one image, so if someone works with multiple images, it will need to have multiple instances the program.

I've noticed that cut'n'paste does not work well between instances of LazPaint, the alpha channel is lost. This is something to improve in next version.
