[英]TYPO3 FileReference converts tiff and bmp to gif
Uploading and using tiff or bmp files in TYPO3 and including them via f:image results them in beeing converted into gif files. 在TYPO3中上载和使用tiff或bmp文件并通过f:image包含它们会导致将它们转换为gif文件。 Im using ImageMagick.
我正在使用ImageMagick。 I couldn't find anything about this issue but i wonder, because even uploading 100% jpg files results into double compression, while uploading bmp and tiff doesn't.
我找不到关于此问题的任何信息,但我想知道,因为即使上传100%jpg文件也会导致双重压缩,而上传bmp和tiff却没有。 Any ideas how to configure typo3 to convert tiff and bmp into jpg and not gif?
有什么想法如何配置typo3将tiff和bmp转换为jpg而不是gif? Can't imagine that this is the right behavior.
无法想象这是正确的行为。

i found out that the decision for the output format is done at 我发现输出格式的决定是在
TYPO3\CMS\Core\Resource\Processing\AbstractGraphicalTask::determineTargetFileExtension
If there is no configuration given it will use gif or png for all non-jpg images. 如果没有配置,它将对所有非jpg图像使用gif或png。 I overloaded the
我超载了
\TYPO3\CMS\Core\Resource\Processing\ImageCropScaleMaskTask
which extends the AbstractGraphicalTask and rewrote the function to properly convert bmp and tiff. 扩展了AbstractGraphicalTask并重写了函数以正确转换bmp和tiff。
Overwrite the default fal config in ext_localconf.php 覆盖ext_localconf.php中的默认fal配置
$GLOBALS['TYPO3_CONF_VARS']['SYS']['fal']['processingTaskTypes']['Image.CropScaleMask'] = \i3\I3Content\Resource\Processing\ImageCropScaleMaskTask::class;
New function: 新功能:
protected function determineTargetFileExtension() {
if (!empty($this->configuration['fileExtension'])) {
$targetFileExtension = $this->configuration['fileExtension'];
} else {
// explanation for "thumbnails_png"
// Bit0: If set, thumbnails from non-jpegs will be 'png', otherwise 'gif' (0=gif/1=png).
// Bit1: Even JPG's will be converted to png or gif (2=gif/3=png)
$targetFileExtensionConfiguration = $GLOBALS['TYPO3_CONF_VARS']['GFX']['thumbnails_png'];
if ($this->getSourceFile()->getExtension() === 'jpg' || $this->getSourceFile()->getExtension() === 'jpeg') {
if ($targetFileExtensionConfiguration == 2) {
$targetFileExtension = 'gif';
} elseif ($targetFileExtensionConfiguration == 3) {
$targetFileExtension = 'png';
} else {
$targetFileExtension = 'jpg';
}
} else {
// check if a png or a gif should be created
if ($targetFileExtensionConfiguration == 1 || $this->getSourceFile()->getExtension() === 'png') {
$targetFileExtension = 'png';
} elseif($this->getSourceFile()->getExtension() === 'tif' || $this->getSourceFile()->getExtension() === 'tiff' || $this->getSourceFile()->getExtension() === 'bmp') {
$targetFileExtension = 'jpg';
} else {
// thumbnails_png is "0"
$targetFileExtension = 'gif';
}
}
}
return $targetFileExtension;
}
Check the $TYPO3_CONF_VARS[GFX][thumbnails_png]
setting through install tool. 通过安装工具检查
$TYPO3_CONF_VARS[GFX][thumbnails_png]
设置。 There are various options how to convert different formats when resizing images. 调整图像大小时,有多种方法可以转换不同的格式。
