Title: How to keep the ratio of an image?
Post by: johanco123 on March 12, 2015, 01:30:35 AM

Hi Bruce

I am using a image control on a form. I want to set the Image Height to '250' and leave the Image Width blank or ''. How can i keep the aspect ratio of the image to display the correct width.

Kind regards
Johan

Hi Johan That should do it. Normally if you nominate height or width and leave the other blank the aspect ratio will stay the same

Hi Bruce

Any suggestions how to get the aspect ratio sorted out on an image control. It is the same with the display control.

Johan

hi Johan,

there's a bit of code doing that in the netweb.clw in the CreateImage method;

  if loc:height and not loc:width then loc:width = loc:height.   
  if loc:width and not loc:height then loc:height = loc:width.

you can comment out this code - I don't think it's needed. I've commented it out for the 8.42 build.

cheers
Bruce
