Browsing a Chinese AutoIt forum, i fall on a little pearl that i want to share with you ! I have already seen water effects example with autoit, but this one is very easy to create using waterctrl.dll Only BMP are supported. Position of Blob water can be set by coordinates and mouse movements (and clicks) when over bmp create traces on water. All files are embeded in script with BinaryToAu3Kompressor. WaterEffect.au3 Hope you like it !

Hello all. I am trying to figure out the best approach to compare PDF outputs for consistency. Currently, this is a human task where PDFs are held up to a light to see if all the values line up exactly with test data. I have to believe there is a better way. That said GDIPlus is a bit of a mystery to me - I have looked at some of the functions - and I stumbled upon >this very useful script in my forum search. My question is: would converting the PDF to an image and comparing the image with GDIPlus be the way to go or is there a different more efficient approach that you would recommend? Any guidance would be greatly appreciated. JFish

I'm trying to use '?do=embed' frameborder='0' data-embedContent>> but none of the examples work. Mostly, I'm just not seeing any pictures, just nothing, a window with some text but no picture. What am I doing wrong? Do these examples work for anybody else?

I'd like to load a BMP file then change chosen color (0xFF00FF) to transparent and save it as PNG file. I'm using a code from other thread. I've modified it a little, but it still doesn't work.

Here's a simple script I'm testing the ScreenCapture function with. #include <ScreenCapture.au3> #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> ; Capture region _ScreenCapture_Capture(@ScriptDir & "\image.bmp", 290,18,1465,652,0) $form=GUICreate("Test",1175,634,290,18,BitOR($WS_SYSMENU,$WS_POPUP),$WS_EX_COMPOSITED) $PSimage=GUICtrlCreatePic(@ScriptDir & "\image.bmp", 0,0,1175,634) GUISetState(@SW_SHOW) MsgBox(0,"","Test of screen cap and display.") . The above script captures an area of the screen (the SciTE editor with this script open), writes it to image.bmp, and displays image.bmp. The problem I'm having is when image.bmp is displayed using GUICtrlCreatePic the result is fuzzy. Here's a SnagIt screen capture of what GUICtrlCreatePic displays. Attached is image.bmp, which is sharp and equivalent to seeing the actual script open in SciTE on-screen. Any suggestions for displaying an accurate rendition of ScreenCapture's output? (Must be borderless, no chrome, etc. -- equivalent to what my test script yields.) image.bmp

To save future readers a little sweat I'm editing my original post to insert the following: After trying various suggested scripting approaches, some of which introduced new problems and some which had the same problem described here, I tried my script and a few others on another computer. No white flashes, tears, glitches. So I brought it back to my main box and disabled the Intel GPU that was feeding a 3rd monitor. Down to two monitors connected to a single NVidia GPU the visual glitches disappeared. Who would'a thought?! That said, some of the replies that follow provide valuable insights into the various ways to skin this cat using AutoIt. Some suggested scripts introduced new problems so they might be instructive about approaches to avoid. Ultimately, JohnOne suggested an elegantly simple script that perfectly accomplishes my goal. --------------------- I want to display a 800x600 picture (i.e., not full-screen) without a border, close-box, title, etc. I then want to replace that picture with another one -- cleanly. Think of an old-fashioned dual-projector slide show where there's no black-out or other interruption to the image on screen. This way I can start with a background image, then add elements to it seamlessly (once called "a build", i.e., pseudo-animation). The image format doesn't matter to me. I can't use an animated GIF or video because my code is doing things in the background between images, so timing varies. I'm having bad luck using an AutoIt form to accomplish this (GUICtrlCreatePic, followed by subsequent GUICtrlSetImage's). The result is a glitch -- usually a white flash or tear in the picture -- at almost every image change. (see 10/10/13 post entitled "random visual glitch when using GUICtrlSetImage"). So I guess that's out. SplashImageOn blanks out the first image before displaying the next (like a single-projector slide show), so it's not seamless -- plus there's still a tiny border visible. $var = Default SplashImageOn("","image1.bmp",$var,$var,$var,$var,1) sleep(2000) SplashImageOn("","image2.bmp",$var,$var,$var,$var,1) sleep(2000) SplashImageOn("","image3.bmp",$var,$var,$var,$var,1) sleep(2000) Any suggestions?

I'm displaying a series of BMP images using AutoIt's GUI capabilities. Here's my initial test code. All it does is test my goal of displaying a picture, then allowing some code to accomplish a brief task, followed by the next picture, etc. The problem I'm having is that sometimes there's a brief visual glitch in the picture when GUICtrlSetImage displays the next picture. This doesn't happen every time but it happens enough to make the result look funky. Any suggestions about what I can do to prevent the glitch? Could it be the specs of the BMP images I'm creating in Photoshop CS6? Under BMP Options I'm using 24 Bit depth, no RLE compression -- ie., the defaults. (note that I've tried using jpg's instead of bmp file without improvement) $form=GUICreate("PowerStrips",900,530,518,272, BitOR($WS_SYSMENU,$WS_POPUP), 0) $cid=GUICtrlCreatePic(@ScriptDir & "\imagebackground.bmp", 0,0, 900, 530) GuiCtrlSetState($cid,$GUI_DISABLE) ;The initial "button" I want to show $PSimage=GUICtrlCreatePic(@ScriptDir & "\image1.bmp", 0,0,900,530) GUISetState(@SW_SHOW) ;show 1st image MsgBox(0,"","test") GUICtrlSetImage($PSimage, @ScriptDir & "\image2.bmp") ;show 2nd image MsgBox(0,"","test") GUICtrlSetImage($PSimage,@ScriptDir & "\image3.bmp") ;show 3rd image MsgBox(0,"","test") GUICtrlSetImage($PSimage,@ScriptDir & "\image4.bmp") 'show 4th image MsgBox(0,"","test") Exit

In a script I'm using the GuiCtrlSetImage command to display a bmp image created in Illustrator. When exporting to bmp from Illustrator the Basic options include 16 bit, 24 bit, and 32 bit. (all are RGB, 72ppi, with anti-aliasing = "art optimized" (though I tried "none" and it made no difference to the outcomes shown)) Following are screen captures of how AutoIt's GuiCtrlSetImage command renders the bmp image. 32 bit original (note ragged edges) 24 bit original (looks closest to original, but there are some black pixel artifacts in the top left chrome border, so it ain't perfect) 16 bit original (note lots of breakup in chrome border and black pixels around border of white silhouette) As you see, the 24 bit capture is the only acceptable one. However, I had to compromise on the graphic because originally it had "inner glow" effects in the white areas. Below is a screen capture of what AutoIt did to this 24 bit image. The only difference between this and the previous 24 bit image is that this one has an inner glow (gray to white gradient along edges of white silhoutte) effect. Either there's a bug in AutoIt or my bmp files are incompatible in some way. Can anyone tell me the ideal specs for a bmp image for use with GuiCtrlSetImage? In case it helps, below are some of Illustrator's Advanced Export-to-bmp options (I used the Basic Modes described at the top). Note also that I brought the image into Photoshop and saved it as a bump there, and I got the same artifacts.

Hi all I am wondering if someone knows what could be causing the images in my GUI to display little black squares all over them. They seem to change depending on how much code is in the file/program. I have attached two examples, the first is from a set of buttons called using GUICtrlCreatePic and they are in BMP format Shows a screenshot of the GUI image on the left and the original images on the right The second is also called using GUICtrlCreatePic but they are in JPG format Shows a screenshot of the GUI image on the top and the original image on the bottom Both of them display the same problem although in earlier versions of the code it seemed to just exist on the BMP buttons, although i havent been watching it closely until i noticed them in both places today. They show up whether the script is compiled or not. Thanks in advance Adam

Identicon.au3 v0.8 A simple UDF to create identicons or visual representations of any hash value. Based on Don Park's original Identicon program. Main features: 3x3 and 4x4 grid patterns.Aside from rotational symmetry there are also checkerboard and Space Invader (mirror symmetry) patterns.Adapted to handle hashes up to SHA512.Save as PNG, JPG, GIF or BMP identicons.Alpha-transparency support for PNG.The UDF and a demo:Identicon.au3 Identicon-Demo.au3 Version 0.8: * Initial public release. To do: * In the checkerboard pattern there is a bias for diamond shapes. * Improve image saving, BMP, GIF and JPG suck, much artifacts and dithering. * Transparency doesn't work with GIF (and BMP?) due to the wrong Bitmap format. * Add some more unique sprite shapes and preferably cap the shape arrays at powers of two as BitAND is faster than a modulus operation.

I know there are snippet threads, but I'd like this one to be specific. I've see quite a few neat GDI+ code snippets (UEZ and Progandy come to mind first) to manipulate, create, etc, and I thought it'd be neat to be able to find them under one thread. I'm going to reserve the next 3 posts because I'm unsure at the moment if it's the "Quote" or "Spoiler" bbcode tags that has the 10 limit. You can link or post the snippets you find or create and I'll title them and put them in the threads for everyone to find. ( Going to have to remember to edit with regular editor! ) Some of these may not have titles, so I may create my own, if the author(s) want(s) a different one, let me know. _GDIPlus_WaterMark.au3 - Author: UEZ - Added: 2012-10-13 - Updated: _GDIPlus_BMPFromMemory – Author UEZ – Added: 2012-10-14 – Updated: Example – Needle Movement (4bit example provided, link to 32bit found in code) – Author: UEZ - Added: 2012-10-14 – Updated:

This is my maze generator. It creates a maze useing the Recursive backtracker witch i found here: http://en.wikipedia.org/wiki/Maze_generation_algorithm#Recursive_backtracker It'll save the finished maze in the a folder with the name Mazes in @scriptdir as Maze (Seed).bmp where Seed is the seed of the maze and size is the size. It usees the Bitmap Libray by evelertoaster find it here: Thanks to MvGulik for cleaning the code. Here's a picture of a finished 25*25 maze: The green dot is the start and the red dot is the end. It can also solve the maze. Here's the solution for the above 25*25 maze.
