Image watermark using IBR and Imagemagick

1025059Jun 3 2015 — edited Jun 5 2015

Hi All,

We have a requirement to create a image rendition with  a watermark text.We are using ImageMagick for conversion and have installed FreeType delegates in the Linux box. normal conversion using the resize command works fine but after using the -draw/-font command, I am getting the error as mentioned below

Starting to create the 'MediumWatermark' rendition of type 'Extra'

Creating rendition with command: /usr/local/bin/convert -resize 352x300> -font -draw "gravity south fill white text 0,0 'copyright'" "/OraApplBin/Oracle/Middleware/user_projects/domains/base_domain/ucm/ibr/vault/~temp/qaecmnode116200/1466/2462.jpg" "/OraApplBin/Oracle/Middleware/user_projects/domains/base_domain/ucm/ibr/vault/~temp/qaecmnode116200/1466/mediumwatermark3/mediumwatermark.jpg"

The 'MediumWatermark' rendition failed. The engine reported the following error: 'convert: unable to open image `gravity south fill white text 0,0 'copyright'': @ error/blob.c/OpenBlob/2584.

convert: no decode delegate for this image format `gravity south fill white text 0,0 'copyright'' @ error/constitute.c/ReadImage/532.'

Finished the 'MediumWatermark' rendition.

Below mentioned is my extraRendition_definitions.hda

ImageMagick=/usr/local/bin/convert

ImageMagic_Watermark=-resize 352x300> -font -pointsize 24 -draw

@ResultSet ImageLibrary

<$ImageMagic_Watermark$> "gravity south fill white text 0,0 'copyright'"  "<$inFile$>"  "<$outFile$>.jpg"

Medium rendition in 352x300 pixels with watermark

@end

Mentioned below is the delegates installed for ImageMagick

DELEGATES     freetype jpeg tiff


I am able to covert the same using command line

convert -resize 352x300  -font -pointsize 24 -draw "gravity south fill white text 0,0 'abcd'" input.jpg output.jpg

Kindly help to resolve the above issue, Please advice if I am missing  any configurations.

Thanks and Regards,

Basudev

Hi Shrinath,

Thanks for your response. I am using "ImageMagic_Watermark" as a variable only. My question is does other Image magic commands like composite/draw/font etc work when we use it in extraRendition_definitions.hda. because the normal conversion as mentioned below works when used in the extraRendition_definitions.hda

convert -resize 300x300> "<$inFile$>"  "<$outFile$>.jpg"

I have the freetype delegate installed on the box, Is the there any further configuration needed

Regards

I have never seen that kind of configuration being set in extra renditions file and used . I am testing it as well to see if it works, will keep you posted with details once tests are completed .

Changed the command as mentioned below in the extraRendition_definitions.hda and it worked

<$inFile$> -resize 500x334^>  -pointsize 24  -draw "gravity south fill grey text 0,12 'Copyright'" <$outFile$>.jpg

Thanks and Regards,

Basudev

Exactly , I was about to put the same details .

Answer

Infact , the way I have done this is :

ImageMagick=/usr/local/bin/convert

ImageMagic_Watermark=-resize 352x300 -pointsize 24 -draw "gravity south fill white text 0,0 'copyright'"

@ResultSet ImageLibrary
