[TYPO3-dev] How to use Image-Object for higher resolutions ?

[Stefan Geith]

Hi Devs,

I'm trying to create PDFs from my HTML via pdf_generator2.
For this, I would like to have 'higher resolutions' of my images
but with sill the same width/height parameters in <img>-tag.

Question:
Is there a way /a trick to get an IMAGE-Object, that renders internally 
a higher width/height than it fills into the width/heigt-params of the 
<img>-tag ?

E.g. Original Image has 1024x768.
What I need is
   <img src="xxx.jpg" width="160" height="120" />
With either xxx.jpg beeing the original (unscaled) image
or xxx.jpg is scaled to (160x4) x (120x4) = 640x480.

Is this possible with cObj->IMAGE ?

If not: maybe new TS-parameters for IMAGE would make sense:
   - image.file.noRescale=1 ==> doesnt rescale the image
          with ImageMagick, but simply calculates the
          height/width-Parameters of the image-Tag
   - image.file.resolution=n ==> rescales image n-time
          bigger than used by height/width-Parameters
