[Typo3-dev] Cropping Function via Flash and IM

[Carsten Bleicker]

Hello everybody,

atm i'm developing a be-extension wich allows you to
crop different images via flash and IM.
i want to display the "image to crop" in a flash movie
wich holds some aspect-ratios presets etc. and a rectangle wich
defines the area you want to crop. near everything works fine
atm. but flash is only able to import external images with type=jpg.
so i have to make a temp jpg-image to import it into flash.
after cropping the original file i have to delete the temp file.

i want to copy the image via t3 IM-functions:

$gfxLib = t3lib_div::makeInstance('t3lib_stdGraphic');
$gfxLib->init();
$gfxLib->imageMagickConvert($this->file,'jpg');

but the file is not created.

near line 2071:
$this->imageMagickExec($imagefile.$frame,$output,$command);


the debug result of function vars:

imagefile=/home/dev/public_html/dev.intern.de/fileadmin/user_upload/_temp_/Unbeschnitten.jpeg
frame=
output=typo3temp/pics/e496ad8b01.jpg
command=-geometry 546x369! -colorspace RGB -quality 70


anybody an idea why the tempfile is not created?

thanks a lot
