Append an image to another image

[dmeier]

Hi,

Appending two images is really easy, if the images have the same width. This seems what you want to do.

Code: Select all

on mouseUp
     put the imagedata of img 1 & the imagedata of img 2 into myData
     create img
     set the height of it to the height of img 1 + the height of img 2
     set the width of it to the width of img 1
     set the imagedata of it to myData
end mouseUp

This script appends the imagedata of one image to the imagedata of the second image and uses the new imagedata for a third image. It is important to set the width and height of the third image to the correct dimensions before setting the imagedata.

Use the export command to export he third image as JPEG.

Kind regards,

Mark

Hi Mark

As I am currently a week end programmer I could check your solution only now. Thank you very much for this, that works fine! That's exactly what I was looking for.

How can i do this with 35 different images like a movie thumbnail?

Hi Seal,

I think the easiest way would be to position the images next to each other manually then group them (set the margins of the group to 0) and import or export a snapshot of the group. That would result in a single image.

You could also place the individual images in the group and then scroll the group if that is what you want.

Using imageData for this kind of thing is possible but rather complicated. Unlike the example above where you want to add an image vertically it is much more involved to do that horizontally. That is due to how imageData is structured. ImageData is basically one long line of information that is then formatted by width and height.
To combine images horizontally your would have to do a lot of calculations.
A snapshot is easy to do.

Kind regards

I tried with snapshot but the image quality is bad. I set the jpegquality is 100 the resolution and quality is inappropriate.

[bn]

Could you upload an image you are trying to take a snapshot of? Or an image similar in quality and size?

Kind regards

Hi Seal,

I've done a quick and dirty piece of code
to show you how to merge ( tile) images in 1 by script.
So, that's the second solution Bernd did suggest to you.

Code: Select all

on mergeImages
   local img0, imgTiles, W, H, L, N
   put the imagedata of image "view" into img0
   put the width     of image "view" into W
   put W * 4 into L
   put the height    of image "view" into H
   
   put 3 into N
   set the width     of image "imageTiles" to W*N
   set the height    of image "imageTiles" to H
   put empty into image "imageTiles"
   wait 1 ticks with messages
   
   put empty into imgTiles
   
   repeat with i=0 to H-1
      local p1, p2
      put 1 + L*i into p1
      put p1 -1 + L into p2
      repeat N times
         put char p1 to p2 of img0 after imgTiles
      end repeat
   end repeat
   set the imagedata of image "imageTiles" to imgTiles
end mergeImages

The original image (left side) has been tiled 3 times (right side):

Changing this code to manage multiple sources images is left as an exercice to the reader....
Hint: put all the source imagedatas in an array, indexed from 1 to Nimages;
then the changes are easy.

PS: I have no idea if this will fullfill the image quality you need!

Happy coding,

Thierry

Hi Seal,

Here is a stack that creates a group of 3 thumbnails from 1 thumbnail and then imports a snapshot from that group.
The point is that I can not notice a degradation of image quality in the snapshot.

@Thierry
I like the snippet of code for manipulating imageData.
Today I feel more like "bricolage"

Kind regards

[SEAL29]

Thank you guys for solutions.

[Thierry]

Ok, I did move on a bit more...

Code: Select all

on mergeImages
   local img0, imgsIN, imgTiles, W, H, L, N
   
   put 3 into N  -- N images sources
   
   repeat with i = 1 to N
      local aLocalJpegFile
      put item i of "KH,JS,QD" into aCard
      put myDesktopFolder & aCard & ".jpg" into aCardFile
      set the text of image "view" to url ("binfile:" & aCardFile)
      wait 1 ticks with messages
      put the imagedata of image "view" into imgsIN[ i]
   end repeat
   
   put the width     of image "view" into W
   put the height    of image "view" into H
   put W * 4 into L
   
   set the width     of image "imageTiles" to W*N
   set the height    of image "imageTiles" to H
   put empty into image "imageTiles"
   wait 1 ticks with messages
   
   put empty into imgTiles
   
   repeat with i=0 to H-1
      local p1, p2
      put 1 + L*i into p1
      put p1 -1 + L into p2
      repeat  with j = 1 to N
         put char p1 to p2 of imgsIN[ j] after imgTiles
      end repeat
   end repeat
   set the imagedata of image "imageTiles" to imgTiles
end mergeImages

[Thierry]

and another step...

Code: Select all

on mergeImages
   local img0, imgsIN, imgTiles, imgTilesRow
   local W, H, L, N
   
   put 3 into N  -- N images sources
   
   lock screen
   repeat with i = 1 to N
      local aLocalJpegFile
      put item i of "KH,JS,QD" into aCard
      put myDesktopFolder & aCard & ".jpg" into aCardFile
      set the text of image "view" to url ("binfile:" & aCardFile)
      put the imagedata of image "view" into imgsIN[ i]
   end repeat
   
   unlock screen
   
   put the width     of image "view" into W
   put the height    of image "view" into H
   put W * 4 into L
   
   set the width     of image "imageTiles" to W*N
   set the height    of image "imageTiles" to H*N
   put empty into image "imageTiles"
   wait 1 ticks with messages
   
   put empty into imgTilesRow
   
   repeat with i=0 to H-1
      local p1, p2
      put 1 + L*i into p1
      put p1 -1 + L into p2
      repeat  with j = 1 to N
         put char p1 to p2 of imgsIN[ j] after imgTilesRow
      end repeat
   end repeat
   -- feed the N image rows:
   put empty into imgTiles
   repeat N times
      put imgTilesRow after imgTiles
   end repeat
   set the imagedata of image "imageTiles" to imgTiles
end mergeImages

and now
most probably what you would like to have, or close...

Code: Select all

constant myDesktopFolder = "/Users/xxxx/Desktop/cards52/"
constant mySourcesImages = "KH,JS,QD,AC,3H,7S,10D,2C,5H"

on mergeImages
   local imgsIN, imgTiles, imgTilesRow
   local W, H, L, Nimgs, Nrows, Ncols
   
   put 9 into Nimgs  -- N images sources, image dest 3 x 3
   put 3 into Nrows
   put 3 into Ncols
   
   lock screen
   -- build an array of imageDatas
   repeat with N = 1 to Nimgs
      local aLocalJpegFile
      put item N of mySourcesImages into aCard
      -- this is where my cards images are stored:
      put myDesktopFolder & aCard & ".jpg" into aCardFile
      -- image "view" must be locked!
      set the text of image "view" to url ("binfile:" & aCardFile)
      put the imagedata of image "view" into imgsIN[ N]
   end repeat
   unlock screen
   
   put the width     of image "view" into W
   put the height    of image "view" into H
   put W * 4 into L
   
   set the width     of image "imageTiles" to W*Ncols
   set the height    of image "imageTiles" to H*Nrows
   put empty into image "imageTiles"
   wait 1 ticks with messages
   
   put empty into imgTilesRow
   repeat with i=0 to H-1
      local p1, p2
      put 1 + L*i into p1
      put p1 -1 + L into p2
      repeat  with j = 1 to Ncols
         put char p1 to p2 of imgsIN[ j] after imgTilesRow[ 1]
         put char p1 to p2 of imgsIN[ Ncols+j] after imgTilesRow[ 2]
         put char p1 to p2 of imgsIN[ Ncols*2+j] after imgTilesRow[ 3]
      end repeat
   end repeat
   
   put empty into imgTiles
   repeat  with j = 1 to Nrows
      put imgTilesRow[ j] after imgTiles
   end repeat
   set the imagedata of image "imageTiles" to imgTiles
end mergeImages

That's all folks!

Hope this will help a few

Thank you, this is a great job.

Hi Seal,

and finally, got some free time refactoring,
renaming few variables and making the code more generic:

Code: Select all

  -- specify number of Rows and Columns!
   put 2 into Nrows
   put 4 into Ncols

Code: Select all

on mergeImages
   local imgData, imgTiles, imgTilesRow
   local W, H, W4, Nrows, Ncols
   local K, C, R, p1, p2
   
   put 2 into Nrows
   put 4 into Ncols
   buildArrayOfImageData  Nrows*Ncols,  imgData
   
   put the width  of image "view" into W
   put the height of image "view" into H   
   set the width  of image "imageTiles" to W*Ncols
   set the height of image "imageTiles" to H*Nrows
   put W * 4 into W4
   
   put empty into imgTilesRow
   repeat with K = 0 to H-1
      put 1 + W4*K into p1
      put p1 -1 + W4 into p2
      repeat  with C = 1 to Ncols
         repeat  with R = 1 to Nrows
            put char p1 to p2 of imgData[ C+Ncols*(R-1)] after imgTilesRow[ R]
         end repeat
      end repeat
   end repeat
   
   repeat  with R = 1 to Nrows
      put imgTilesRow[ R] after imgTiles
   end repeat
   
   set the imagedata of image "imageTiles" to imgTiles
end mergeImages

Kind regards,

Thierry
