Here is how to resize images by width and height, but images (portret and lanscape) will keep ratio/proportions.

And images in Blog layout will allways have same dimensions in px (for instance, all images will be 150 px width X 100px height.)

 

Just tested and it works perfectly.

Decide width and height in px, then new thing is background-color for part of image block that is over.

So, black color will be top-bottom or left-right, in relation to pictures, depending if you have landscape or some picture with great height. (you can use any color you want)

And chose everything below to suit your needs (tex,S,L,XL)

 

//Medium image                $handle->image_resize = true;                $handle->image_ratio = true;                $handle->image_convert = 'jpg';                $handle->image_ratio_fill = true;                $handle->image_background_color = '#000000';                $handle->jpeg_quality = $params->get('imagesQuality');                $handle->file_auto_rename = false;                $handle->file_overwrite = true;                $handle->file_new_name_body = $filename.'_M';                if (JRequest::getInt('itemImageM')) {        $imageWidth = JRequest::getInt('itemImageM');        } else {        $imageWidth = $params->get('itemImageM', '100');        }        if (JRequest::getInt('itemImageM_Height')) {        $imageHeight = JRequest::getInt('itemImageM_Height');        } else {        $imageHeight = $params->get('itemImageM_Height', '115');        }        $handle->image_x = $imageWidth;        $handle->image_y = $imageHeight;        $handle->Process($savepath);

If it could be some way to override class.upload in K2 Admin.

Amazing what you can achieve with this.

But, you have only 5 shots.

Thanks, but where did I put that code ?

 

So, your code could be repeated with different px value for each format (S, L, XL...) ?

 

I don't really understand why did you put a color background, your code don't crop the image so it fills the space ?

 

Thanks again ;)

Sorry, it is

administrator/components/com_k2/models/item.php

 

Be carefull with this. You need to be sure that this tweak is not used ( XS, S,XL,M,L ) for some Category where you don´t want it this way.

You can use this code for any type of images (all 5 - XS, XL, S, M, L). Just adapt it as you wish.

If you dont use $handle->image_background_color = '#000000';  then default color is white. It is up to you to decide.

Ok ;)

 

But I don't really understand.

If I have an image : 300px * 450px

 

I want to have a full thumbnail (no black stripes...) of size 200px * 100px.

 

Your script can do it ?

 

Thanks ;) 

You can have same color as your template background. (white, or some else)

Your picture, doesn´t matter if it is landscape od portrait, will allways be centered in image block.

 

It wont lose proportions.

 

If you don´t understand. You can have same thumbs in Category blog in pixels (remember borders ?), and still don´t lose proportions and ratio for tex portrait of Barack Obama and for some panorama picture.

Height is key here. Your pictures wont lose proportions and wont decide height in px.

And you have whole picture naturally, not cropped from center or similar.

So your script do that :

 



 

I'm wrong ?

Yes, like this. This would be default, white background. There is not some portrait picture there, but principle it like this.

I chosed black because i find it more elegant sometimes.
