      sometimes!
      Running the script below and entering a for All seems to work every time Running it and choosing 1 for One returns a gibberish string However with the same functions, I have seen it succeed when 1 is chosen, i.e. show the value for the test property ID 0x0103 as OLYMPUS DIGITAL CAMERA I have also seen GetOne() succeed when a diagnostic MsgBox() is added,  and when I include my debugging functions, so the problem appears to be a memory location being overwritten, probably in a DLLStruct.. call.
      I know that value OLYMPUS DIGITAL CAMERA is correct from Irfanview and from running GetAll().
      All but one of the _GDIPlus functions were written by ChrisL. I have modified those that returned a DLLStruct object such that they now return an array.
      Both getting one and getting  all involve calling _GDIPlus_ImageGetPropertyItemValue() which I wrote, so perhaps the problem partly lies with ChrisL's functions as modified.
      Suggestions?

      The following code is one of my many attempts to get the value of a string property from an image. It doesn't work. I know that IMAGEDESCRIPTION has a string value.
      In one of my many attempts, I did get the string OLYMPUS .., which I know is correct from IrfanView, but I can't get it again.
      How should I get this string?

      I have found that:
      there are 276 functions in Authenticity's GDIP.au3 (written for 3.3.6.1) that are not in 3.3.14.2's GDIPlus.au3.  there are many constants in his GDIPConstants.au3 that are not in 3.3.14.2's GDIPlus.au3, but there are some that are. So:
      GDIP extras.au3 contains functions that are not in GDIPlus.au3. They have been extracted from GDIP.au3 The revised GDIPConstants.au3 has constants that are duplicates of those in GDIPlus.au3 commented out. They are attached.
      I have done limited testing on 3.3.14.2 with GDIP extras.au3 and the revised GDIPConstants.au3 included.
      I have undertaken this effort in thanks for the help with GDI+ that I have received on this form, especially from UEZ.
      Authenticity's thread is here. For those who do not 7zip, I am attaching his GDIP as a zip file. It contains many examples.

      UEZ has kindly provided me with code that rotates an image per a line: see here
      Because I want to trim a photograph after rotation, I need to crop the photo. I wrote code which calls _GDIPlus_GraphicsSetClipRect() to do this, but it places spurious stuff in the corners: see 2.jpg attached.
      I want only the trimmed photo to show.
      The original jpeg is also attached.
      The arguments to _GDIPlus_GraphicsSetClipRect() come from solving 2 simultaneous equations: if a and b are the width and height of the original photo, find x and y, the width and height of the rotated and cropped rectangle;
      a = x cos(ang) + y sin(ang)
      b = x sin(ang) + y cos(ang)
      My solution is:
      x = (b * sin(ang) - a*cos(ang)) / (sin(ang)^2 - (cos(ang)^2)
      y = (b * cos(ang) - a * sin(ang)) / (cos(ang)^2 - sin(ang)^2)
      To try to get a handle on the problem, I have temporarily added in several lines in Case $btn. In 2.jpg, you can see that the rectangle bounding the area to be retained is in the wrong place.
      The code is:

There are graphics objects, graphics contexts and PDI+ bitmaps. How are they related?
      Help would be much appreciated.

      Dear AutoIT Community.
      I am currently working on a program that will display lots of images in a scroll down GUI.
      I create the GUI based on the number of images, which works fine.
      But all images I place using GuiCtrlCreatePic above a threshold of around 32000 pixels (cant say exactly) are placed at negative locations and finally will reach 0 again
      and will then populate on top of the images placed there before.
      For $i = 1 To $Images[0] ; Get picture dimensions $hImage = _GDIPlus_ImageLoadFromFile($ImgRep & $Images[$i]) $iX = _GDIPlus_ImageGetWidth($hImage) $iY = _GDIPlus_ImageGetHeight($hImage) _GDIPlus_ImageDispose($hImage) ; Resize & place images in GUI $Pic[$i] = GUICtrlCreatePic($ImgRep & $Images[$i], $Spacer, Round($yPos, 0), $MaxImgWidth, $MaxImgWidth * ($iY / $iX)) $yPos = $yPos + $MaxImgWidth * ($iY / $iX) + $Spacer $log = $log & "|" & $yPos $currentlut = $Images[1] Next I have found a limit at 32767 pixels for some GUI elements when googling around.
      Can someone tell me how to circumvent that?
      thanks!
      cheers
