[Imc-andorra] [st3@riseup.net: [ahimsa-tech] sf-active image class]

[Pseudo Punk]

Hey,

We're gonna start with making thumbnails & resizing to big pictures.

we though the following values make sense:

thumbnails: width: max 120 / heigth: max 100
images for articles: max 600 (h & w)

can someone confirm if this is ok to you or propose other values asap ?

Bart

i and PseudoPunk are going to put on the new code for sf-active uploaded
images thumbnailing, resizing and dividing

it will work just for sf-active sites

the new system works this way:
1) thumbnails are made for searching purposes: they are displayed in the
search results page
2) midsize pics are made to be displayed within the article body: if the
size of an image exceeds some limits (width, height and bytes) it will be
resized or compressed according to those limits: original images will be
linked to midsize ones, so that when ppl click on a resized image, a popup
with the original pic is shown
3) the uploads will be divided in different directories for date, i.e.
/uploads/yyyy/MM/

how to get this working

part a - configuration
basically, you need some variables to be added in sf-active.cfg, in your
local config path (i.e. /imc/sf-active-new/yourimc/local/config/)

we are already adding them, but commented out, so you just need to uncomment
them out (and, however, they are quite self-explanatory =)

while they are commented out, no thumbnailing _and/or_ resizing will take
effect (you can set just some of them, for example setting only
'max_image_size' will just make image compression)

all variables are in pixel, unless otherwise noted

1)
$GLOBALS['image_thumbnail_x'] = z // sets the thumbnail width
$GLOBALS['image_thumbnail_y'] = z // sets the thumbnail height

2)
$GLOBALS['max_image_x'] = z // sets midsize limit width
$GLOBALS['max_image_y'] = z // sets midsize limit height
$GLOBALS['max_image_size'] = z // sets midsize limit weight, in bytes

part b - old pics resize
you need to make the thumbnails and midsize for old images too (only kenya
imc don't actually need it to do it =)

i coded a function in image_class.inc to do this, but it's _really_ better
that you ask me or PseudoPunk to get this done, because it's not as easy as
an 1-2-3

PseudoPunk will do for imc wvl and for zmagbr now, and asking for liege

- ---
so, what should you do:
1) if you want this feature to be enabled for your imc, ask me or PseudoPunk
(on this list or on #ahimsa, irc.indymedia.org) to have your old images
converted and your articles regenerated according to new filenames
2) configure as in part a all the times you want (we are probably gonna make
a pics regeneration process directly accessible from admin interface asap)
3) enjoy =)

we're gonna do as well some compression controls that can be set up in the
publish form by users
