[#5919] where to increase memory which is needed for upload

OK - I got the files. Please look at the entries of 13th may (because I tried to upload a single file on the 13th may (useing ImageMagick))

Imagick isn't configured properly and is failing with a fatal error as noted below in your log.


Switch to GD2 within CB > Configuration > Images and see if uploading images still errors. Your host can find the latest binaries below.

www.imagemagick.org/script/binary-releases.php

Now my hoster installed a new ImageMagick Version 7.0.2. Then I tried to upload a Gallery item again (within CB). It still didn't work. Then I switched on the debug mode...the following error has been prompted on the xcreen:


Fatal error: Undefined class constant 'Imagick::IMGTYPE_TRUECOLORMATTE' in /home/www/web180/html/joomla/pre_production/libraries/CBLib/Imagine/Imagick/Image.php on line 815

....line 815 is here --> look at the '*****' in the file Image.php

private function setColorspace(PaletteInterface $palette)
{
static $typeMapping = array(
// We use Matte variants to preserve alpha
PaletteInterface::PALETTE_CMYK => \Imagick::IMGTYPE_TRUECOLORMATTE,
PaletteInterface::PALETTE_RGB => \Imagick::IMGTYPE_TRUECOLORMATTE,
PaletteInterface::PALETTE_GRAYSCALE => \Imagick::IMGTYPE_GRAYSCALEMATTE,
); ********************************************************************************************* this is line 815 ************************

if (!isset(static::$colorspaceMapping[$palette->name()])) {
throw new InvalidArgumentException(sprintf('The palette %s is not supported by Imagick driver', $palette->name()));
}

$this->imagick->setType($typeMapping[$palette->name()]);
$this->imagick->setColorspace(static::$colorspaceMapping[$palette->name()]);
$this->palette = $palette;
}

Do you have any idea what is wrong ? ...the hoster could not help me with this error message

regards

For some reason Imagick 7 just flat out removed those constants that have been around and used since Imagick 3. I've no idea what to suggest other than downgrade Imagick. CB uses the Imagine library, which requires a minimum of Imagick 6.2.9. Below is an issue ticket reported to Imagine about this issue.

github.com/avalanche123/Imagine/issues/496

Fix has already been submitted by someone and pending merge. Once merged we can update our Imagine library to be compatible with Imagick 7. I've added a bug ticket to keep note of this.

Hi Kyle - according to the issue that ImageMagick 7.0.2 didn't work in my environment you analysed that the 'Imagine' library has to be adapted...you opened a ticket. Based on this comment I have done some 'experiments' based on different environments (at the same hoster)

Environment 1 **************************************************** (my test site)

Joomla 3.6.2
CB 2.0.14
CB Gallery 1.0.6
PHP 5.6

Result: ImageMagick was selectable in the 'Images' tab of CB config, but the upload of images didn't work


Enfironment 2 ***************************************************** (my test site)

same as 'Environment 1' but with PHP 5.5

Result: ImageMagick was NOT selectable in the 'Images' tab of CB config (only GD as default visible)...with GD only files up to approx 1 MB can be uploaded. If I try to upload biger files I get a memory issue


Environment 3 **************************************************** (my test site)

same as 'Environment' 1 but with PHP 5.4

Result: ImageMagick was NOT selectable in the 'Images' tab of CB config (only GD as default visible)...with GD only files up to approx 1 MB can be uploaded. If I try to upload biger files I get a memory issue


Environment 4 ***************************************************** (this is my current prod site with some 'old' components)

Joomla 3.3.6
CB 1.9.1
Profile Gallery 1.2
PHP 5.4
Image Magick 7.0.2 and GD ar BOTH selectable in the 'Portrait' tab

Result: Image Magick (7.0.2) and GD as well work EXCELLENT and I it is possible to upload even really big files (e.g 5MB) and I didn't get a memory issues

*************************************************************************

Question: How is it possible that 'old' libraries (see Environment 4) manage to work with ImageMagick 7.0.2 ...and in the 'old' environemt I also do not feel any memory upload restrictions...neither with GD nor ImageMagick (compared to CB 2.0.14)

CB 1.x isn't using the Imagine library for image processing. CB 1.x also didn't utilize the majority of Imagick API. So it doesn't have the constants that were removed in Imagick 7.x. There's nothing I can do until it's fixed in Imagine, which the bug ticket is still open (see link in my previous reply).

You certainly should be able to upload images larger than 1 MB with GD. If not you may have some other server configuration problem or the pixel size of your images is astronomical resulting in a 1:10 ratio once uncompressed. Don't upload 6000x6000 photos or anything of the sort (to any website really) as once GD uncompressed it it's probably going to consume all your available memory.

For now just run Imagick 6.2.9 or a slightly newer version than that. Older releases can be found below.

sourceforge.net/projects/imagemagick/ or www.imagemagick.org/download/

Will also be reviewing the possibility of switching image processing libraries if this continues to go unfixed.
