Hi all,
Having controll over placing-formating-sizing graphics and Images will
be a big advantage for the many users who uses OO in a bid more
professional way !
We are a Belgian based Editing-house who uses exclusifly OO to produce
all the WEB-content and we planned also to let produce our editors
all the Printed magazine-pages .
I am working o a way to let users import graphics into a WriterDoc, with
an preview who is giving Size and Resolution off te imported images and
if necacery chaging the ImageFormat, size and resolution, depending on
witch medium (web-print-copie) the page will be showed.
I found finaly a way to find out the "format", "size" and "resolution"
of a Image using the "GraphicProvider.QuaryGraphic" (I will be happy
to share this basic-code with the community) But during finding a way to
place -resizing-reformating the images i stumbeled on a lot of "deadends"
Placing an embedded -grahpic into a WriterDoc (with the GUI or withe
the API) gives different results depending if you placed it as a
linked-graphic or and embedded-graphic.
Embedded gives us the orinal dimensions (as difined in the
Imagefile-header) gives us the correct "orginal-size" , the image had a
"scale of "100%" and a correct "image-size "
Linked gives us the a wrong "orginal size" (based on 96 DPI) a
"scaling" with a percentage to optain a correct "image size" !! Is
this behabior wanted or is it a bug ?
Before we place the image we can resize and reformat the graphic and
define if we "embed" or "link" the grahic. I tried different ways to
acomplish this task, it can be done, opening a hidden drawdoc and then
place the grapic as a Shade, and finaly "exporting" the drawpage using
the filteroptions to re-size and re-format the imagefile. To avoid the
hidden drawdoc i tryed differend ways to acomplis the same task:
Using the "GrapchicProvider.storeGraphic" and defining the MIMEtype was
a prommesing option , I can do the re-formating, but i found noway to
re-size the imagefile, there exist some filteroptions but found noware
any documentation.
Exporting the "Shape" instead of the DrawPage "with a filter" avoid
the use of a hidden DrawDoc , works the "filtername" gives us the right
format but: the filter ignorges the re-sizing options.
Exporting the Writer-Drawpage let crashes OO (no pagesize i supose)
Any hints to resolve this deadends will be very welcome, and just maybe
someone can explain why the filteroptions only works during the exort of
a DrawDoc-drawpage and how a filter cen be used with
GraphicProfider.StoreGrahpic
Thanks
