png with background transparent into gui without border
Hi guys, I would like to make a gui borderless viewing a png image with transparent background.
pretty much has to be visible only the png image with no background..you have any simple example?
still it provides the image with the background...
A new image search solution
Im a new AutoIt user, im from Spain and i would like to share here my own image search detection method.
What's about it?
It's not perfect, but with it you don't need to use any DLL file. You don't need to distribute the image file with your final AU3 Script, or Exe if compiled. The image size does not affect to the detection speed. It's bug free (i believe).
You can find here as an attach file, a distro package with all you need, and it includes a simple how-to guide.
Im going to paste here the how-to guide:
How to use this AutoIt image detector:
Install JRE (Java Runtime Environment), without this you can't execute Java Applications (.jar files). Open the Java tool named AISD with double click on it, or "java -jar aisd.jar" in the cmd. In AISD, open the image you want to detect in your script. Remember: the upper left pixel of the image, MUST be a not common color in the background if you want a fast detection. Then you will get a script file if you want, or only a clipboard copied version, full ready to paste into your main script because this one comes with extra help codes. Anyway, the generated code is the $sign definition of the image (calm down, point 3 explains what is the $sign and it's easy).
Paste the mentioned code in your main script, and try to follow the sample_usage script. If you know how to write au3 codes, it should be very easy. In general terms, all you need is to include image_search.au3, and then you can use the func image_search($sign, $width, $height). You need also the get_image_sign() function, that calculates the first parameter for image_search(). The get_image_sign() function is the one you have generated at point 1.
image_search() returns the center point of the target image. The func needs the $sign from the image, width and height. This $sign is the "footprint" of the image, in the form of an array of 9 integers. In most of the cases the $sign should be enough to identify the image, this is useful because using the $sign instead of the real image let you get a small script and a fast detection. You can also delete the image once you get the $sign. This $sign has always the same size (those 9 integers, it does not matter if the original image is small or big). How can you define the $sign for a certain image?, you don't need to generate the $sign, AISD does (point 1). Follow the sample_usage script and you will get it.
Files in this distro package:
* AISD.jar: The already explained Java app.
* image_search.au3: The library or module with the resources that lets you detect images.
* sample_usage.au3: The mentioned sample_usage script. It contains the smallest example, but i think it should be ok for learning purposes.
* sample_usage.exe: The sample_usage.au3 script compiled (au3 -> .exe). You can execute this to see the image_search() func working.
* sample_target.png: The image to be detected in the sample_usage. You can delete this file and the script will be fine.
* OffsetCalc.jar: It's only a Java tool to calculate the offset to transform an XY point into another one. It's useful if you want to use apply_offset function (from image_search.au3). Both things are only necessary when it's hard to find a version of the target image with upper left pixel in the way mentioned. As you can imagine, the idea is to detect another image and then apply the offset to get the real coordinates of the original target image.
Identifying Button in Toolbar When There is no ControID
I want to click on a button that is inside a custom ToolBar on a nonAutoIT created form. I've been using MouseClick but that fails if the toolbar is detached or if the form is resized.
There is no ID associated with the toolbar but there is a handle. I'm thinking that to get the handle I need a ControlID but that only gets me to the toolbar and I'd then need to have a way to identify the position of a button in order to click on it.
I'd found a discussion about identifying the position of a noname button by, I believe, it's Tip text back in December but I can't find it now. Memory is a bit fuzzy on how I even got to the topic because at the time I was searching for something else. I'll continue to search but if anyone has seen the topic, or knows of another solution could you please point me in that direction.
[Solved] Get stream size
I was looking for methode to get the stream size of a picture from memory , wihtout need to write stream data to disk the then use filegetsize
