And only the widths varies (80% for the first picture and 40% for the second picture)? > For both items the hight is 80% of the screen right? And only the widths varies (80% for the first picture and 40% for the second picture)? Yes. The height of the <picture> element is set to 80% here <picture mypicture> / items = myitems / height = 80% / width = 0% / position = (50%, 50%) </picture> and nowhere is it changed. The width is set on a trial-by-trial basis here <trial mytrial> / ontrialbegin = [picture.mypicture.width = list.widths.nextvalue;] / stimulusframes = [1=mypicture] / validresponse = (57) </trial> and it is sampled from the <list> element. Which value, i.e. width, the list returns depends on the picture item the trial will display. Do keep in mind one thing: Inquisit will not, under any circumstances, distort the original image's dimensions. They will remain intact, i.e. Inquisit will not "stretch" an image just because you set an excessive width or height. I.e. suppose you have an image that is 400 pixels wide, and 300 pixels high, then -- not matter what you do, the 4:3 width/height ratio will always be preserved, even if you set the <picture> element's dimensions to something absurd like width = 5% & height = 90%. Hey Dave, thanks so much for this explanation and your help! I didn't know that Inquisit doesn't distort the image's dimensions. Know everything makes completely sense too me!!!!!! And it works! Thanks and best, Julia

For my study I need to present images on a screen. Unfortunately, I don't know the exact size. The picture I want to present also have different sizes. Some of them have a vertical format, others a horizontal. I want to present them in the following way: All pictures should have the same hight (80 % of screen hight), the picture ratio should stay the same. So the picture shouldn't be cut. Furthermore, the picture should be presented in the middle of the screen. I tried already tried it with the following code: <picture japanese> /items = japanese /select = noreplace /position = (50%, 50%) /height = 80% /select = noreplace </picture> but that doesn't really work... Has anybody an idea? Best, Julia Hey there, just an additional question: Is it possible, to set the width only for horizontal pictures to 80% and make here the height flexible. For vertical pictures the height should than be 80% and the width flexible. I just don't have a clue how to do that... The only thing you can do is encode the height you need for each individual image item in a <list> and then set the <picture> element to that width dynamically. I.e. <block myblock> / trials = [1-2 = mytrial] </block> <trial mytrial> / ontrialbegin = [picture.mypicture.width = list.widths.nextvalue;] / stimulusframes = [1=mypicture] / validresponse = (57) </trial> <picture mypicture> / items = myitems / height = 80% / width = 0% / position = (50%, 50%) </picture> <list widths> / items = (80%, 40%) / selectionmode = picture.mypicture.nextindex </list> <item myitems> / 1 = "01.jpg" / 2 = "02.jpg" </item> Hey Dave, thanks a lot for your answer. I think, I don't really get what you are doing in your code. Especially this peace of code: / items = (80%, 40%) What are you doing here and where are the 40% from? How does Inquisit know which picture is vertical, which horizontal and when to set the hight to 80% (for vertical pictures) and when to set the width to 80% (for horizontal pictures). Thanks for your help!!!!! Julia <list widths> / items = (80%, 40%) / selectionmode = picture.mypicture.nextindex </list> The <list> is tied to the <picture> element. The 1st item in the list -- 80% -- indicates the width for the 1st item in the <picture> element, 01.jpg. The 2nd item in the <list> indicates the width for the <picture> element's 2nd item -- 02.jpg. In essence, this is the same as https://www.millisecond.com/support/docs/v4/html/howto/howtopairs.htm Great, thanks, I think I have got it. :) But then the height of both pictures is 80%, isn't it? I only want it to be 80% for vertical images. Maybe I will try it differently: I want to fix only the longest dimension of every painting at a standard size (say 1000 pixels), the other dimension should be set to default (so that the proportions of the image don't change)... Thanks and sorry for asking so much!

For the second item ("02.jpg"; so the horizontal image) the height is set to 80% and the width to 40%. That also shouldn't be so: The hight should be set to 80% and the width should be allowed to vary and shouldn't be fixed to 40%... Is there a possibility to do that? Best Julia

For my study I need to present images on a screen. Unfortunately, I don't know the exact size. The picture I want to present also have different sizes. Some of them have a vertical format, others a horizontal. I want to present them in the following way: All pictures should have the same hight (80 % of screen hight), the picture ratio should stay the same. So the picture shouldn't be cut. Furthermore, the picture should be presented in the middle of the screen. I tried already tried it with the following code: <picture japanese> /items = japanese /select = noreplace /position = (50%, 50%) /height = 80% /select = noreplace </picture> but that doesn't really work... Has anybody an idea? Best, Julia Hey there, just an additional question: Is it possible, to set the width only for horizontal pictures to 80% and make here the height flexible. For vertical pictures the height should than be 80% and the width flexible. I just don't have a clue how to do that... The only thing you can do is encode the height you need for each individual image item in a <list> and then set the <picture> element to that width dynamically. I.e. <block myblock> / trials = [1-2 = mytrial] </block> <trial mytrial> / ontrialbegin = [picture.mypicture.width = list.widths.nextvalue;] / stimulusframes = [1=mypicture] / validresponse = (57) </trial> <picture mypicture> / items = myitems / height = 80% / width = 0% / position = (50%, 50%) </picture> <list widths> / items = (80%, 40%) / selectionmode = picture.mypicture.nextindex </list> <item myitems> / 1 = "01.jpg" / 2 = "02.jpg" </item> Hey Dave, thanks a lot for your answer. I think, I don't really get what you are doing in your code. Especially this peace of code: / items = (80%, 40%) What are you doing here and where are the 40% from? How does Inquisit know which picture is vertical, which horizontal and when to set the hight to 80% (for vertical pictures) and when to set the width to 80% (for horizontal pictures). Thanks for your help!!!!! Julia <list widths> / items = (80%, 40%) / selectionmode = picture.mypicture.nextindex </list> The <list> is tied to the <picture> element. The 1st item in the list -- 80% -- indicates the width for the 1st item in the <picture> element, 01.jpg. The 2nd item in the <list> indicates the width for the <picture> element's 2nd item -- 02.jpg. In essence, this is the same as https://www.millisecond.com/support/docs/v4/html/howto/howtopairs.htm Great, thanks, I think I have got it. :) But then the height of both pictures is 80%, isn't it? I only want it to be 80% for vertical images. Maybe I will try it differently: I want to fix only the longest dimension of every painting at a standard size (say 1000 pixels), the other dimension should be set to default (so that the proportions of the image don't change)...
