[Note my comments below are from a thread in [discuss] subject
'Resizing Images']
This problem began simply with the issue of cropping and image so
that what was displayed was to the
user's choice but leaving the entire image incorporated in the file
which of course impacts file size. It
was suggested that cropping delete unwanted portions of the image. I
raised questions about the
process which are discussed by myself and others below. In addition
to the basic question I think all
these issues should be considered by the developers should they
elect to change the way cropping is
done.
When dealing with raster images there are a few things that should
be optimized by the user. (1) the
height and width of the image, (2) the resolution of the image, (3)
the dpi, (4) the palette (number of
colors).

Hi Clarke,
Clarke Rice schrieb: Hi Sigrid I don't understand, why you are
complaining. Have you tried the new version of OOo? The cropping
tool
for images has - in my opinion - improved a lot. I don't know how
Word
does the cropping (I haven't used Word for some time now), but I
think
that OOo does it now well enough that you don't need any extra
program
like GIMP to crop the pictures you want to insert. Try it out.
What you
say is true. However in OOo 3, if I insert a large image and
resize it,
Writer still saves a huge image. It would be useful if Writer
allowed
me to save the final document with images at the resolution they are
actually used with, or to save without cropped portions of images
still
being retained in the saved file.
Good idea. For impress, have You tried the presentation optimizer (a
downloadable plugin)?
Please (if not done yet) register at OOo and file an enhancement
issue
for this. Maybe a menu entry or button can be added for cropped
images
to apply the crop and get back to a non-cropped, reduced image.
I can see a logic for retaining the whole image after cropping in that
it allows the author to re-crop the image at any time. Clearly the
downside is the images are larger than the original poster wanted. It
would seem that in order to satisfy the original poster there would
need
to be a way to tell the application no further changes to the images
are
desired. Now this could be done automatically when the document is
saved. (I don't like this approach). There could be a 'save and
minimize
images' option added. There could be a separate command to minimize
image(s) to the size at which they are currently defined. Should
this do
all images, selected images, only one selected image?
I mention this only to point out that while the request for the
original
poster sounds pretty straight forward it really is pretty complex.

Hi Douglas,
like anything else in software development, the idea is simple
until you
realise what the knock-on consequences could be!
imho it should work like this:
- User crops/scales image
Ok good start. <g>
- User can hit 'save' and the image is saved at full resulotion
I assume it would be saved at full resolution and full size allowing
anyone to change the cropping, resolution, rotation...
- Or right-click on the image and select an option to apply
cropping to
the saved image (plus compression to 100/200 dpi) - MSO does this.
You were on a roll until you right-clicked. (Mac mouses don't got need
no stinkin extra buttons). I suppose it would be alright Mac users are
learning to adapt to the deficiencies of the Windoze world. <g> But
for
maximum compatibility (which is a stated goal) coding programs so you
don't need a 14 button mouse or more specifically can do everything
with
a one button mouse would seem to be in order.
- OR, user can set a global option to save images with cropping
applied
to whatever is saved. Maybe another global option to save at 100/200
dpi or the original resolution?
Not sure of the value of 100 dpi. 72 dpi is a choice that maps to
traditional typeset standards (i.e. points), 200 maps to fax images,
300
and 600 dpi map to a whole bunch of low cost inkjet printers.
You thoughts?
Still might be nice to have a few global options that, when the user
is
finished messing with their images, would discard information that has
been saved out side the cropped area as well as setting the final
resolution and so forth to all the images. I assume that when the
document is finished and the output device has been selected setting
all
images to match this device would be appropriate. This would be
another
global option.
The begs the question: If the user plans to send some out by fax (200
dpi), some to old Macintosh pin-printers (72 dpi), an inkjet printer
and
laser printer (300 and 600 dpi), and PDF files (maximum resolution)
then
how would you handle that?
Also in the case of maximum resolution if some originals are 300 dpi
and
others are 2400 dpi should you set all at 300 dpi or leave them at
their
original resolution?
Sounds simple, though I imagine it could be a headache to get right in
programming. The image would presumably have to get sent out to some
sort of JPEG routine, have its resolution changed, then be sent back.
I don't think the programming is half as hard as figuring out what to
program. <g>

regarding
the definition of what you want to do globally.
