[NOT REALLY SOLVED] CGSmartImage Responsive images?

thefrozen · Post by **thefrozen** » Fri Oct 09, 2015 6:03 pm

Hi,

I don't know if I am doing something wrong or whether it is intended behaviour:
On my system, CGSmartImage resizes images, but it always resizes them to the SMALLEST size given as breakpoints.
For example:
Screen resolution: 1920x1080
Breakpoints: 200,400,600,800
Resulting image width: 200 not 800 as expected.

Is my expectation wrong or something else?

Kind regards,

thefrozen

You might post the tag being used in the template with any other settings etc., so someone can help better.

Thanks, I didn't post settings and other details because I just wanted to know whether my expectation is the problem. But you are right, to receive help, more is probably needed. So here the settings:

Template in the <head>:

Code: Select all

{CGSmartImage action=responsive}

Code in the content block:

Code: Select all

{CGSmartImage src="path_to_image.png" alt="alttext"}

Settings:
Responsiveness is enabled.
Assume responsive cookie is not enabled.
Breakpoints: 200,400,600,800

Cache path is set and works fine.
Default autoscale filter is "resize".

Thanks!

Kind regards,

thefrozen

Edit: See below!

I found a solution. By examining the code I found that max_width or max_height has to be defined. According to the module help this is only possible for csgi_convert. So I edited my template and added

Code: Select all

{cgsi_convert max_width="800"}{content}{/cgsi_convert}

instead of just

Code: Select all

{content}

.
After changing the image link to plain HTML image tags instead of {CGSmartImage} it worked as intended. Awesome!

So for others seeing this confusing problem:
Make sure that you set max_width (or max_height) to a good value. To do this, use cgsi_convert in the template.

Edit:
Unfortunately this fixes the width to 750 but still doesn't resize.
Looking closer at the code I suspect a typo:
Line 620 in class.cgsi_utils.php:

Code: Select all

$lval = max($opp['max_width'],$opp['max_height']);

Should this be:

Code: Select all

$lval = max($opp['d_max_width'],$opp['d_max_height']);

?
I'll try..
Answer: Nope.. Still doesn't resize.

Kind regards,
