Chris very true i didn't specify width and height because the images that are being attached to the pdf have variable dimensions. hmm so that's the behaviour of FOP. i actually tried changing the page size to 40x40inches and still the image did not display... as with regards to the command line warnings... i don't see them if there are any coz i just access the xml file via browser say i resulted to 1234.xml file i access it via http://FQDN:8080/cocoon/xmlfiles/1234.pdf hope this information could further give enlightenment to this case... any other suggestions? all the best!!! pal, benjohn - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Thus, you could specify a maximum width (or height) and it would scale to that size. You just need to be sure the corresponding image dimension doesn't put the image off the page.

Image Size Issue
hi all,
Good Day!!!
i have read lots about images in PDF and have successfully
displayed an image already however i noticed on my system that it
could not accommodate an image greater than 60kb to 70kb of size,
what happens is i get an empty pdf file when the image size goes
higher than mentioned.
before creating the xml file i call:
~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
org.apache.fop.image.FopImageFactory.resetCache();
~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
as mentioned on one of the docs frees up memory to accommodate
image transactions. now on the XML file here is what i use:
~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
figurephoto
image=http://FQDN/images/drawings/B747/ThisIsATest-1234-
5678/.061_67-11-018-Sht5_RevA.jpg//figure
~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
and on the XSL file:
~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
xsl:template match=figure
fo:block
xsl:apply-templates/
/fo:block
/xsl:template
xsl:template match=photo
fo:block text-align=center
fo:external-graphic src=[EMAIL PROTECTED]/
/fo:block
/xsl:template
~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
my system runs on a Pentium 3 800Mhz with 256Mb RAM having:
~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
Operating System: Linux RedHat 7.2
Java: j2sdk1.4
Tomcat: jakarta-tomcat-4.1.27
FOP: fop-0.20.5
Cocoon: cocoon-2.1.2
~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
ok where does this all boil down to? ... Image Quality... when i lower
down the image file size to 60Kb all the small figures, numbers and
tables get blurry to the point that even when the document gets
printed those small numbers could not be read anymore not to
mention the actual drawings/diagrams the original file size with
good quality could go up to 17x11inches in dimension @ 100 ppi
quality = 400Kb file size imagine bringing that down to 60Kbto
70Kb... i was hoping if anyone has a workaround for this case so as
i could still maintain the sharpness in detail of the images attached
in the PDF file... herewith i also attach the 60kb image for a better
view of the quality disintegration thanks for the attention... all the
best!!!
