the problem has been solved now. I made two zip file for everone.
thanks for Lukas to help me.

here is them
no1
u can only install it

no2

i'm sorry that I have a mistake,don't download tha administrator.rar..thanks

maybe those are not steady , then u can tell me the problem what u runinto trouble.or ask Lukas . he is a great man

Hack file administrator\components\com_k2\models\item.php which is responsible for thumbs creation from K2 side.

For example this will crop Small image to square where width and height is taken from width settings:

//Small image
$handle->image_resize = true;
//$handle->image_ratio_y = true;
$handle->image_convert = 'jpg';
$handle->jpeg_quality = $params->get('imagesQuality');
$handle->file_auto_rename = false;
$handle->file_overwrite = true;
$handle->file_new_name_body = $filename.'_S';
if (JRequest::getInt('itemImageS')) {
$imageWidth = JRequest::getInt('itemImageS');
} else {
$imageWidth = $params->get('itemImageS', '200');
}
$handle->image_x = $imageWidth;
$handle->image_y = $imageWidth;
$handle->image_ratio_crop = true;
$handle->Process($savepath);


as you can see 1line is commented out and 2 adeed...

See docs for class.upload.php at verot.net and play with available parameters.
Just add line(s) $handle->somethingofyourchoice
That library create that thums..

thanks very much,Luckas

Hi,Lukas..thanks for your reply.
Now,according to your way, it's perfect..then i want to add Height setting on K2 Parameters..it could be?

of course, I have used this way : $handle->image_y = $imageWidth*0.8;
but it's shot of perfection.

Yes, but still as a hack...
1. Add required value(s) to administrator\components\com_k2\config.xml
e.g.
param menu="hide" name="itemImageS_height" type="text" default="200" size="4" label="Item Small image height (in px)" description="" /

2. define new variables in mentioned file administrator\components\com_k2\models\item.php

//Small image
$handle->image_resize = true;
//$handle->image_ratio_y = true;
$handle->image_convert = 'jpg';
$handle->jpeg_quality = $params->get('imagesQuality');
$handle->file_auto_rename = false;
$handle->file_overwrite = true;
$handle->file_new_name_body = $filename.'_S';
if (JRequest::getInt('itemImageS')) {
$imageWidth = JRequest::getInt('itemImageS');
$imageHeight = JRequest::getInt('itemImageS_height');
} else {
$imageWidth = $params->get('itemImageS', '200');
$imageHeight = $params->get('itemImageS_height', '200');
}
$handle->image_x = $imageWidth;
$handle->image_y = $imageHeight;
$handle->image_ratio_crop = true;
$handle->Process($savepath);

I have hardcoded this only in models\item.php so i haven't it tested...

You Are Great !!!!
thank you very very much~:) i'm going to test it
Lukas said:Yes, but still as a hack... 1. Add required value(s) to administrator\components\com_k2\config.xml e.g.

ok, test it and let us know if it works..
By the way, this is direct way to custom/heavily hacked K2... Without possibility to simple update... :|
Agreed, that images tweaks are (atleast) for me really needed...

Regards,
l

agree. This should be an option.
First "hardcoded" method definitely works. Here are some screenshots...

in fact, the result is beauty..



haha, lukas.
however,we have to modify category.xml as config.xml, so we can set width and height on category config

you're right.

Hi Lukas, after tested that. maybe something wasn't referred to.
of course,i can input Height value, then ever thumbnail' height equal to half of width
it means that won't work

won't work at all? Some error messages? Error reporting on? What exactly is (not) happened..? First metod works?
Have you commented out //$handle->image_ratio_y = true; etc ;)

l

of course , i do. $hanle->image_ration_y=false;

no error! everthing is normal
you are right! first method work. ($handle->image_y = $imageWidth*0.8; ) this way is work too
however, when i add height setting on K2 then input value of height. it's seem to invalidation. heght is also 200px.

is new height value from params stored in DB?..
Is possible "echo" that values?..
l

I guess, it dose not get new height value , in fact, I have inputed it
can u have a try

Lukas said:is new height value from params stored in DB?.. Is possible "echo" that values?.. l

param menu="hide" name="itemImageS_Height" type="text" default="200" size="4" label="Item Small image height (in px)" description=""


1.


2.

It looks "doublesized" height. Hard to say without atleast look to your code in both files...

p.s. "$hanle->image_ration_y=false;" is exact typo? there is ration

Well, this is wrong:

if (JRequest::getInt('itemImageS')) {
$imageWidth = JRequest::getInt('itemImageS');
$imageHeight = JRequest::getInt('itemImageS_height');
} else {
$imageWidth = $params->get('itemImageS', '200');
$imageHeight = $params->get('itemImageS_height', '200');
}

should be? :

if (JRequest::getInt('itemImageS')) {
$imageWidth = JRequest::getInt('itemImageS');
} else {
$imageWidth = $params->get('itemImageS', '200');
}
if (JRequest::getInt('itemImageS_height')) {
$imageHeight = JRequest::getInt('itemImageS_height');
} else {
$imageHeight = $params->get('itemImageS_height', '200');
}

p.s. for clear view, am just frontendguy, so php i guess+assemble+tweak ;)

No, //$hanle->image_ration_y=true; it also does not work. height value is 200px
it does't matter I follow the first method for the moment. Wishing the next patch will add height setting.
Thank you all the same. Lukas

Lukas said:It looks "doublesized" height. Hard to say without atleast look to your code in both files...
p.s. "$hanle->image_ration_y=false;" is exact typo? there is ration

Weird, it works for me.

Example code from both files:

model/item.php

//Small image
$handle->image_resize = true;
$handle->image_convert = 'jpg';
$handle->jpeg_quality = $params->get('imagesQuality');
$handle->file_auto_rename = false;
$handle->file_overwrite = true;
$handle->file_new_name_body = $filename.'_S';
if (JRequest::getInt('itemImageS')) {
$imageWidth = JRequest::getInt('itemImageS');
} else {
$imageWidth = $params->get('itemImageS', '200');
}
if (JRequest::getInt('itemImageS_height')) {
$imageHeight = JRequest::getInt('itemImageS_height');
} else {
$imageHeight = $params->get('itemImageS_height', '200');
}
$handle->image_x = $imageWidth;
$handle->image_y = $imageHeight;
$handle->image_ratio_crop = true;
$handle->Process($savepath);

config.xml (with<> at start and end of course, forum cut out full string...)

param menu="hide" name="itemImageS_height" type="text" default="200" size="4" label="Item Small image height (in px)" description="" /

In config i fill 10 for height and 110 for width and correct (expected=zoom to center and crop to width 110xheight 10) result attached.
