I created a bitmap in draw 15" x 131" then right clicked the image and selected "Edit Bitmap". The image grew to 19" X 131"... I did this again just to verify and got the same results. I resamled the image back to 15". This is a big concern as we process all our printed images this way. Somebody please advise.
Thanks!
Hi,
May I ask if you first made a document in CorelDRAW and then converted to Bitmap?
Did you then select the bitmap and then click edit btimap?
When you clicked edit bitmap, then did the bitmap change when still inside CorelDRAW or did it open the bitmap in PHOTO-PAINT?
I did see a change in size height when opened in Photo-Paint, but width kept.
Yes I clicked "edit Bitmap" and it did not change sizes in Coreldraw. I have two monitors with draw on one and PP on the other. I can see the sizes on both screens.
I tried it again this morning and got the same results...
I tried drawing a box 15" x131 the same size and converting it to 300dpi bitmap. I then clickeed "edit Bitmap" and it grew again in height.
I had another person in the office do the same thing and got same results... the height % changes to 131% The Aspect Ratio "on" is not defaulting.
15H x 131W @ 300dpi X6 is not keeping aspect ratio... If i select it manually it corrects the issue.
This does not happen at 100dpi it seems to only happen at 300dpi. If it was a resoulution issue then it should have been the width not the height that was effected.
I think we need to take this step by step.
First of all, when you convert the 131 x 15" (width should always be the first value) object to a 300 dpi bitmap, you hit the 30,000 pixel limit (131 x 300 = 39,300) and therefore the resolution will be limited to 229 dpi for the width. The bitmap will be 131 x 15" at 229 x 300 dpi.
Then tell us the exact steps. You're taking it to PhotoPaint via "Edit Bitmap..." and then what do you do in PP?
If I do this and make any change, like adding a line or whatever, in PhotoPaint, and then just exit PP and save the changes, the bitmap is still 131 x 15" at 229 x 300 dpi in Draw. What step have I missed?

Hi Ronny,
you have answered the question. The width pixel value is changing due to the pixel limitation...and following your above explanation the width "would" decrease in relation to the height! i.e. the height is unchanged in pixel count, but the width is changed (decreased) in pixel count. CorelDraw is then converting the height to 229dpi to match the width dpi which results in its physcical width increasing. I hope that made sense lol.
Best regards,Brian.

That is almost certainly the key to the answer.
Some operations, including export to bitmap, do not allow separate horizontal and vertical resolutions to be selected. One of those operations is being performed later, and the resolution in both dimensions is being taken as 229.
The obvious "solution" would be to change CorelDraw's convert to image so that if it hits the resolution limit in one dimension, it should apply that limit to both dimensions -- ie, creating a bit image at 229 x 229 dpi.
Possibly a better solution would be to seek out all the operations that presently take only the resolution of a single dimension and change them so that they use both, but that is probably a bigger exercise and still likely to overlook something.
Meanwhile, I presume that if the bitmap is created at 200 or 229 dpi the problem will not be seen.
