Can you add an option to set the height of the image instead of width? about imgapp HOT 5 CLOSED

Thank you for your comment. In your comment, you want to modify the height but you don't want to modify the width. Is my understanding correct?

Thanks for your quick reply. Excuse me if I was unclear. With your function, doResize, I can input the width for an image to scale it, but keep the same aspect ratio. However, I found out that for vertical images, width (in your function) means the 'longest' side, so the vertical side. This was a bit confusing. But the real problem for me is that I have an maximum length for the horizontal side (of an vertical image). Which with your function would be height. So when I set the width of a 4:3 vertical image it's height will be longer then if I set an 16:9 vertical image with the same width. Therefore I'd like to set It's height to a specific value and scale it accordingly. This way the image fits my boundaries. I'm not very experienced with google script so I can't figure this out myself. Hopefully you'll be able to help. If you still have doubts about my question, I could make some screenshots of my problem with annotations.

Thank you for replying. I'm really sorry for my poor English skill. I couldn't understand about "vertical images". And unfortunately, I cannot see the vision of your issue. But I can show you the method of resize of this library. You can see the detail information at here. If this is not useful for your situation, I'm sorry.

I figured it out with basic google script functions, if other people find this, this may be of use:

//[...]
//create image with width of 500 and correct aspect ratio
//if it is vertical image this also works (width is always the width)
var newWidth = 500;
//oImg contains the appended image
oImg = oImg.getParent().asParagraph().appendInlineImage(blob);
// Calculate (aspect) ratio
var orgWidth = oImg.getWidth();
var orgHeight = oImg.getHeight();
var ratio = orgHeight/orgWidth;
//Calculate new height for width of 500 and same ratio
var newHeight = newWidth*ratio;
//Set new height and width to image
oImg.setWidth(newWidth).setHeight(newHeight);

I'm glad your issue was solved.
