Hello group

I would like to know if I can stretch an image in QImage, but only in one direction.
That would be only in the vertical or horizontal, but not both.

An example would be to make a 7x10 image into an 8x10, without cropping.

I can do this in photoshop, but I would rather do it in QImage but I have not figured out how.

Help?

If you are wanting to do things that PS/PSE do in Transform, you'll have to do it there.  QI is really for tweaking printing output.

I too would very much appreciate this capability in Qimage.  For me the benefit would be to fit an entire image within an exact size outer dimension if additional borders or various sizes are added in Qimage.  This would result in a very minor and in many cases visually unnoticeable non proportional stretch - for example for abstract images where a border is already part of the original image.

Having to create multiple original images to fit different border configurations is counter to the Qimage concept of using one source image for multiple output variations.

Not sure.  Let me give an example for illustration purposes.  I am given an image with an embedded border that is 2:3 ratio.  I first need to print as 4x6 borderless.  It prints perfectly, no cropping, no image or border lost.  Then I also need to print same image on 4x6 card but with a 0.1" Qimage added white border around entire image.  This means I need to either crop the image if I want even borders which cuts off part of the border that is already part of the image (very noticeable and not acceptable) or I can have a 0.1" border on short side and 0.07" on the long side.  This delta in border is noticeable - it looks like a sloppy cut job.

Instead what would be nice if if Qimage allowed the image to be non-proportionally stretched to fit into the resulting 3.8x5.8 ratio needed to print with a 0.1" border.  In almost all cases this small amount of non-proportional stretch is not detectable and acceptable.

Seth,  I unfortunately have not had time to try this yet (although in the past I have used B and B+ borders)  But logically/mathematically there is no way that using a total print size of 4x6 with a border within can be done and retain a true 2:3 ratio image unless that image is either cropped or non-proportionally resized to the new ratio that results by putting a border inside a 4x6 total print size.
If using B within print size already non-proportionally resizes the image that goes inside the border that is something I did not realize, if it doesn't then that is the exact new capability I am asking for.

There are many things to screw up in Qimage.  It would be very easy to control via a checkbox.
I am not adding borders in photoshop or the like - often they are part of the original abstract image.  Today I have two or sometimes even three .tiff versions of nearly the identical image with every so slightly different aspect ratios so I can print this series with two border types and without - such a waste of hardrive space.  Before I got into this series one thing I liked about Qimage was that I could have one source image and print it in a variety of aspect ratios by cropping in Qimage.

Anyway my reasons are not to make a noticeable artistic change to image, but to accommodate these small aspect ratio changes for very slight different fits. (don't even get me started on how to adjust for same issue for different levels of overspray depending on which printer I am using)

At some risk I'll ask  .....
Do you use Qimage to disable overspray and then tweak the page margins in Q to compensate for (consistent) alignment errors? Do this and save the print set-up for each printer/page size. Easy to recall anytime. 

On borders, I'm sure Fred's suggestion would work for you, look at that option and maybe compromise a little on what you think is the answer.
We are just trying to help!

Yes I do that, which works for my general landscape and photographic printing, but not for other types of artistic images and applications as the resulting print space is not an exact ratio depending on for who and what I am printing for.  In one application am given geometric designs that need to have entire image printed and mounted to variety of media, but do not require zero geometric distortion.

I think some people may be set or limited in imagination in what an 'image' is and rightly can't imagine 'distorting' a portrait or carefully planned landscape for a fine art print - I wouldn't either.   But I don't see Qimage as just a tool printing fine art prints, but as a tool for printing images.  For the later options for fitting such images in a specific space are more important than zero geometrical distortion.  I also find the comparison to 'fun house' distortion overblown.  These very small proportional changes are not even noticeable without side by side comparison.

Sometimes or actually most often I do 'compromise' on borders (actually not compromise as I too prefer uneven borders for 'fine art' prints) sometimes the application requires perfectly even borders.

Right now I feel restricted by this limitation in Qimage, not enabled.   Yes, this can be done in photoshop or the like, but the resulting manual calculation to resize exactly to slight variations in print size in photoshop and bring back to Qimage to print gets very tedious, especially with modifications to sizing and borders.
