_GDIPlus_BitmapCreateBlurBitmap()

Recommended Posts

Yashied

This function allows you to blur the specified GDI+ bitmap with different force of blur (see screenshots, 1 - source image, 2 - blurring image with L=5, 3 - blurring image with L=10). The source bitmap may be of any color depth, the output bitmap is always 32 bits-per-pixel with alpha channel. The function creates a few parallel threads (up to 8), that significantly reduces the time consumption. It's worth noting that the blurring is performed for all channels, including the alpha channel.

The following shows the basic algorithm for a simple blur of bitmap written in AutoIt. Unfortunately, it is not possible to solve using AutoIt because the processing of even a small picture may require too much time. For example, blurring image 100x100 can last a few seconds. To solve this problem, I compiled the time-consuming part of code (main loop) to machine code. This solved the problem of the time consumption but I wanted to get better results, especially for large images (more than 1000x1000) and large blur radius (10+). Then I divided the source image into several parts and started the blurring of each part in a separate thread. Now it's become quite good. See below for a complete example written for Autoit 3.3.12.0.

; Scans the source bitmap pixel by pixel
For $Yi = 0 To $H - 1
    For $Xi = To $W - 1
        $A = 0
        $R = 0
        $G = 0
        $B = 0
        $Count = 0
        ; Calculates the average value for each color channel of source bitmap (including alpha chennel)
        For $Yj = $Yi - $L To $Yi + $L
            For $Xj = $Xi - $L To $Xi + $L
                If ($Xj >= 0) And ($Xj < $W) And ($Yj >= 0) And ($Yj < $H) Then
                    $ARGB = DllStructCreate('BYTE B;BYTE G;BYTE R;BYTE A', $pBitsSrc + ($Xj + $Yj * $W) * 4)
                    $A += $ARGB.A
                    $R += $ARGB.R
                    $G += $ARGB.G
                    $B += $ARGB.B
                    $Count += 1
                EndIf
            Next
        Next
        ; Writes the calculated color to the corresponding pixel of destination bitmap
        $ARGB = DllStructCreate('BYTE B;BYTE G;BYTE R;BYTE A', $pBitsDst + ($Xj + $Yj * $W) * 4)
        $ARGB.A = $A / $Count
        $ARGB.R = $R / $Count
        $ARGB.G = $G / $Count
        $ARGB.B = $B / $Count
    Next
Next

      Hi Community,

      I'm looking for a way to do a Video Overlay GUI or something like that. The idea is to create a GUI which plays a video loop (with transparency/alpha channel) in front of an other GUI. Before you asking why - because I don't believe that GDIPlus can do it out of the box. My skillset for that kind of graphical things isn't good enough to do that, but here are some specialist like @UEZ maybe who can help.

      Example alpha channel video (visualized as animated *.gif):

      I tried to do the light rays effect directly with GDIPlus, but honestly that's a bit too difficult for me. I would be very glad and grateful if there are some suggestions, ideas or recommendations.

      Code for the Video play:
       
      Example video "End.mpeg":
       
      The next challenge is that the overlay GUI should be not clickable. If I hover over the overlay area, I want to have the possibility to control the GUI or what ever, in the background. But if there is any chance to make it with GDIPlus as a Video Overlay for light rays, I would prefer that approach instead of my crazy work-around idea.

      Thanks for any suggestion - I'm grateful!

      I had thought that _GDIPlus_ImageClone($hImage) removes all property items, but I now know that it copies property items.
      What is the easiest way of copying an image that has property items to another image that does not have property items?

      Only available on Vista+ os: double click with rmb on list items to use alternative screenshot functionality (beta)!
      When 'Grab Screen' is clicked you can hold down the ctrl key to switch to 'grab controls' mode. Control under mouse will be framed red.
      ctrl + shift will take the screenshot of appropriate control. To capture GUI menues you can press rmb which simulates the lmb. When a menu is opened press shift additionaly to capture it.
      Press and hold only the shift key to capture any region on the desktop using freehand capturing - release it so capture marked regions!
      Or just mark resizeable area which you want to grab. Press CTRL key to grab marked area or right mouse button to capture the marked area every x seconds for a duration of y seconds.
      When saving the image just enter the extension you whish to use (*.jpg;*.png;*.bmp;*.gif;*.tif;*.pdf). Big thanks to taietel for his PDF UDF!

      I think that _GDIPlus_ImageGetPropertyItem should return a Property Item that can readily be set as a property of another image. Why would one want to do this? A script might (as one of mine does) edit an image of a .jpg file then write the result to a .jpg file. In editing it, in my case, the number of horizontal and vertical pixels change, and the date/time edited should be set as a property. All other property items remain the same. Other GDI+ users may change other properties.
      So an approach is to copy all the property items from image1 to image2, then update a few properties.
      M$ provides a Property Item class (id, length, pointer to an array of values) but _GDIPlus_ImageGetPropertyItem returns something different.
      I think that, wherever reasonable, UDFs that are wrappers for M$ methods should work like M$'s methods. _GDIPlus_ImageGetPropertyItem does not do this:
      While M$ returns 2 values for a value that is a ratio of 2 numbers,  _GDIPlus_ImageGetPropertyItem returns numerator/denominator as a single value (often a Double). _GDIPlus_ImageSetPropertyItem (when included in GDIPlus.au3) will be unable to set ratio property items properly because it cannot know what the numerator and denominator are. So copying such property items will not work properly. M$ has a Void* buffer where the buffer is an array of values but _GDIPlus_ImageGetPropertyItem() returns the values in the same 1-d array as id, length and type. M$'s approach produces a 1-d array with the same number of elements for all property items while _GDIPlus_ImageGetPropertyItem produces a 1-d array with various numbers of elements. To me, this is not good programming practice. For a photo from a Sony camera, the worst case has 1-d array with 67 elements. When combined into a 2-d array with the property items of all properties, there are 66 rows and 67 columns, with many elements not used. So I suggest that _GDIPlus_ImageGetPropertyItem look like this:

I have tested this code by updating and adding property items to torus.jpg and to a photo taken by a Sony camera. The code for implementing and calling _GDIPlus_ImageSetPropertyItem will be fairly simple [see below].
