optional disabling of subsampling

Hi,

Neo writes:

i've created a patch to gimppaintcore.c which allows subsampling to be disabled. this is very useful for pixel-precise work and watermarks.

could you please elaborate how this is different from using the pencil tool?

however.. i've looked around and i'm having difficulty understanding how to add an interface to that [ie. put a 'disable subsampling' option in some part of the preferences dialog, and make the 'disable subsampling' value be stored in gimprc] . the documentation is unhelpful regarding info on this particular subject.

if you really think a global preferences option is adequate here (I don't think it is), you probably want to use the latest CVS or wait for 1.3.11. We are currently redesigning the gimprc system. The new code makes it much easier to add a new option.

Salut, Sven

BTW: Do you have a real name? Neo is used by me for cvs commits and all my accounts, so it might cause some confusion.

It would allow to use brushes with a real alpha mask in pixel-exact mode...

Bye,

pattern for gimp_register_magic_load_handler

Hi all,

I've got a bunch of files file_name.001, file_name.002, file_name.003, ... Each pixel is coded with 2 bytes. So I decided to write a loader for this type of files. But the extensions parameter to gimp_register_magic_load_handler doesn't accept a pattern like "%03d" to say that the file extension is a 3 digit integer (padded with zeros).

How to tell Gimp to recognize file extension .001, .002, .003, ... ?

Any hint would be very appreciated! Sylvain

I don't think that this is possible, but you shouldn't rely on file extensions anyway. Your file format certainly has a header of some sort that can be used to detect the format.

if someone would either explain (generally) what sort of changes i'd need to make, or actually make the changes, i'd appreciate that.

the current patch is attached; note that the conditional check for disable_subsampling is not there. currently it checks a condition which will always be true (== meaning that disable subsampling is always ON).

yes, exactly.
