TYPO3 Core

Sorry, I described this not exact enough.

The original image e.g. is 3000x2000px.

If you insert a magic image in rte it has a default size, e.g. 600x400px.
If don't touch this default image size, you get a downscaled image (600x400px) in frontend.

If you change the size of the image in the rte to a bigger one, e.g. 900x600px, the image don't get scaled to 900x600px in frontend, but has the original size which is 3000x2000px in this example.

In 6.2 seems to work.

It get scaled now, but it's not possible to get a bigger size than 300px width, also when I raise maxWInText. Will recheck again.

I'm having the same problem with TYPO3 6.1 and would be good if this could be fixed soon ;-)

I have had the same problem with Typo3 6.2. There is a default configuration of the max image width ($magicImageMaximumWidth) in the TYPO3\CMS\Core\Resource\Service\MagicImageService with a default value of 300. It is possible to change this value in your PagsTSConfig.

RTE.default {
buttons.image.options.magic.maxWidth = 1000
buttons.image.options.magic.maxHeight = 1000
}

It seems, in FrontEnd a wrong configuration array is passed to

TYPO3\CMS\Core\Resource\Service\MagicImageService::setMagicImageMaximumDimensions

So changing "RTE.default.buttons.image.options.magic.maxWidth" works in Backend, but in FrontEnd it defaults to max. 300px width + 1000px height...

For a working solution in FRONT + BACK-end, i need to add this configuration at the moment (TYPO3 6.2.3):

RTE.default.buttons.image.options.magic.maxWidth = 770
RTE.default.buttons.image.options.magic.maxHeight = 2000
RTE.default.buttons.image.options.plain.maxWidth = 770
RTE.default.buttons.image.options.plain.maxHeight = 2000

RTE.buttons.image < RTE.default.buttons.image

I had the same problem and comment above led me to the right direction. Notice, I was loading the TSConfig via the programmatic way in ext_tables.php which was working for images dimension in the backend but not on the frontend. So, I had to revert and includes as "INCLUDE_TYPOSCRIPT" in the page properties.

# Add page TSConfig (which does not work in the context of the FE)
$pageTsConfig = \TYPO3\CMS\Core\Utility\GeneralUtility::getUrl(
    \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extPath($_EXTKEY) . 'Configuration/TsConfig/Page/config.ts'
);

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPageTSConfig($pageTsConfig);

UPDATE: It looks this configuration is sufficient buttons.image.options.magic.maxWidth = 600 if set in the Page TSConfig on the page property (in the database). If put as external TSConfig, RTE.buttons.image < RTE.default.buttons.image was required for me.

Fabien: For me the same problem occurs, if RTE.default.buttons.image is set within the page properties. (TYPO3 6.2.6).
