I did create a watermarked picture myself and used the given function to dewatermark. This way we can see the best result possible to expect and if it is worth fiddeling. The result so far: the result after the function used: http://www.pic-upload.de/view-25838856/dewm.png.html the origin image ...

Ok. I tried escaping the parenthensis within exec() and it works now: :oops: exec('convert image1.jpg \( watermark.png -resize 41.5% \( +clone -alpha extract +write mpr:WEX \) -compose Multiply -composite -negate \) -gravity center -compose ModulusAdd -composite \( mpr:WEX -negate \) -alpha off ...

hi Thanks all for your help. @Bonzo it just returns an empty array followed by a "1": Array ( ) 1 @snibgo @fred I am under linux (CentOS/PHP), no need to escape the exec(..) parathensis; the convert function seems to work under "other" conditions. i will try to narrow down by seperating some stuff.

Thanks snibgo. Unfortunately it doesn't change the result, no processing nor error. exec('convert image1.png ( watermark.png ( +clone -alpha extract +write mpr:WEX ) -compose Multiply -composite -negate ) -gravity center -compose ModulusAdd -composite ( mpr:WEX -negate ) -alpha off -compose ...

hi trying to get the watermark only results in a cut out of the watermark (which is white-transparent) with the whole background still in presence, code from post snibgo 2015.01-10T04:22:17. so i recreated the watermark with inkscape since the font used is available. I now have a watermark pic in ...

hi, thanks snibgo.

about 500 pictures. so we are able to detect the common repeating pattern and then create the watermark.png out of it?
that sounds powerful. if you give me a hint regarding functions i will try and show off the results.

Thanks

Please have a look at the linked picture in the starting post. this is exactly how it looks like. Yes, the watermark png is partially transparent. Unfortunately i couldn't find the watermark image on the server since they upgraded the CMS and the upload has been replaced by a non-watermark upload 4 ...

hi Thanks Fred. There was a GD function like this involved laying a half-transparent image over the image. <?php $watermark = imagecreatefrompng('watermark.png'); $photo = imagecreatefromjpeg($_GET[photo]); // center watermark on the photo $wx = imagesx($photo)/2 - imagesx($watermark)/2; $wy ...

Hi We used a default script to create thumbs with watermark and unfortunately did not keep the origin image. http://www.pic-upload.de/view-25798013/flowRoot2998.png.html http://www.pic-upload.de/view-25798013/flowRoot2998.png.html the watermark is always the same text and centered across images. I ...

Hi Just want to share some links to create 3d images. It can astonishing easy be done in photoshop/inkscape and imagemagick too i guess. here 2 examples to test if you already got "the view": http://www.magiceye3ds.com/Images/image3d.jpg http://joyerickson.files.wordpress.com/2012/01/magic-eye.jpg ...

Good day everyone I try to enlarge a picture like this: $width = $width * 4; $height = $height * 4; exec("convert src_images/monkeys.png -adaptive-resize ".$width."x".$height." resized_adaptive.png"); exec("convert src_images/monkeys.png -resize ".$width."x".$height." resized.png"); The results from ...

Using PnG's in decreased quality like suggested here http://www.imagemagick.org/Usage/formats/#png_formats Size and processing time decreases up to 97% and quality too. In some cases it might be appropriate to create a bicolor png (4mb compared to 140 mb) and than add features in postprocessing. In ...

FMW42 Unfortunately no line-spacing in GD. Use can create it with ressource intense php scripting though $newY=$y+($i * $size * $spacing); imagettftext($image, $size, $angle, $x, $newY, $color, $fontfile, $lines[$i], $spacing); Same counts for word-wrapping. It's not fun with GD considering doing it ...

Thanks anthony. I saw your 2nd reply and edited my above. I will try PNG8 and report back about info about ressources used, it might be of interest for others. For the last part; masking and cuting; IM is perfect, hope to do the text also with IM (png8), see soon.

Hi Anthony Thanks for the info. I thought in IM it might be an even faster way by using some options to reduce processing, quality and therefor size. Considering your statement i can assume it is not. right? I love IM since its very versatile. My project might be unusual (whole sites of text to ...
