I have CorelDraw 11. and need help understanding how something works with the File size of Corel Documents?
If I import a photo into CorelDraw and then I go to Bitmaps and then RES Tab. Then in here I make it 2 inch Heigh and 300 DPI and save this as a CorelDraw DOC. the files size is 752 kB.
Now if I re open this same CorelDraw Document and click on the photo and the drag the corner handel in to shrink the photo and save this CorelDraw Document again.
If I check the file size again of the Document it is still 752 kB why is it the same size?
I know it is the same photo in the Document but I did drag the handels and made it smaller so I thought CorelDraw would then make the Document smaller.

In addition to Brian's excellent explanation, I'd like to add a couple of things:
Scaling a bitmap in a vector based program, like CorelDraw, will keep the number of pixels but change the size of each pixel.This because a vector drawing doesn't have any fixed grid that each pixel has to fit into.
In a bitmap editor, like Corel PhotoPaint or Adobe Photoshop, the pixel grid size is fixed, and therefore the number of pixels has to be reduced (or increased) instead when you scale.
I believe that there is quite a number of posts regarding this theme but... to simplify things. There r 3 things on which image depends: size as in dimension (mm, cm, inch, etc), pixels and dpi (ppi).
When u set 2 of them (which r important to u / for example - u need image in 3x3 cm and at 300 dpi, pixels will set automatically) third will always be set automatically. That way u have control to adjust image for your needs.
Something similar is happening in CD. When u scale image (not resample), image is smaller with higher dpi (by default). It is still the same image and it still occupy the same amount of space (in KB/MB). But if u resample it, than outcome will change depending which 2 of 3 characteristics u set...

Hi Ronny, I like your image, but I wonder my version helps: there are no white spaces between pixels (less potential confusion) and also shows how downsampling permanently removes color info.
I did want to know what Brain used CorelDraw for?

I know I have my intelligent moments, but you don't have to call me brain I mainly use Photo-Paint. I use it for image manipulation, enhancing photos, skin-smoothing, extra. I use CorelDraw to a far lesser extent for basic layouts, certificates, fliers, personal layouts & posters, any type of document that I want to look more attractive. How about yourself?
Best regards,Brian.
