Clear History feature request

[deathstroke50]

I've been having a few 'out of memory' problems with Paint.NET (despite my 2 GB RAM). Mostly it happens when trying to add layers to the drawing, and seems more likely to occur the more I have in my history. Unless I'm missing something there isn't really a "Clear History" command/button/whatnot.

As such, this is a feature request for a 'clear history' button or menu item or what-have-you. I managed to add my own using the PDN sourcecode. Not pretty or perfect, but probably works... probably... Though I'd prefer to have something official.

(If you're wondering, the problem is arising mostly because I'm working on a picture 4256 px by 7120 px with 7 layers >_< )

Cant you just save the picture, close pdn, and reload it?

[deathstroke50]

Normally I might, but considering that the save/close/load process can take 30 s to a minute, I generally find it too inconvenient to do every time I want to add a layer (something that I may do several times in a series of add/merge/add/merge/add/merge). Adding 30 s between them is disruptive to drawing.

I could have sworn there was a clear history feature in here, but I cant find it. Ive never had any problem with not enough memory, but if they dont have this feature, they need it.

If you've managed to add this yourself through the source coude perhaps you could wrap it up in a .dll and make a plugin out of it.

I think (and I may be wrong) that, at present, you can only add plugins to the Adjustments or Effects menu's - and this would probably sit better in the Edit menu.

Just a thought, though I'm not a programmer and have no idea if it's even possible to create such a plugin.

I'm 95% sure it's not, but perhaps we shall wait for the final word from BoltBait and/or Rick.

prior to 3.05 there was a clear history button. rick removed it

* Removed: The "Clear History" button has been removed because it was not very useful

[toe_head2001]

It needs to make a come back!

[jake2k]

i think i remember rick saying that the history doesn't save to your ram but instead the HDD

[pyrochild]

i think i remember him syaing that too! but you know how it is with the things i remember rick saying ... lol

[Rick Brewster]

Having a Clear History button in 3.xx won't help you any. That's why I removed it in 3.05.

In 2.xx it did make a difference, but only because there was a gross inefficiency in the History window itself, whereby each row in the history window would consume 3-4 user/GDI handles. In 3.xx this is fixed.

Trust me, you don't need the button. It's snake oil.

So, to compute the memory requirements for an image, the following formula can be used:

(W x H x 4) x (L + 2)

4256 px by 7120 px with 7 layers

So (4256 * 7120 * 4) * (7 + 2) = 1,090,897,920 bits.

Roughly 1 GB of RAM, just for Paint.NET.

Edit: It's a Giga bit, not byte.

B=Byte

b=bit

1B=8b.

Actually, Bob, that original formula is referring to Bytes, not bits.

(4,256 * 7,120 * 4) * (7 + 2) = 1,090,897,920 Bytes

Actually, clearing history helped my ram, even in the 3.xx's. I have FreeRam Xp, it monitors your ram and updates a toolbar icon live. Clearing the history sometimes freed up to 10 mbs and over on large pictures.

Description of "FreeRam Xp" from their website:

A popular program to optimize and defragment RAM for Windows XP.

Sorry to tell you, CommanderSozo, but "memory defragmenters" are snake oil. Don't waste your money on them. Any performance improvement you got was purely psychological, and not real.
