Re: Image manipulation
Here is my very basic test code that seems to work. Create a new project, make sure component gb.Image is included. Add 2 textboxes and 1 button. Pre-load the text boxes with the paths of 2 equal sized images (I used jpegs). ImageSub.png The code:- Public Sub Button1_Click() Dim indexX As Integer Di...

Re: Image manipulation
...I'm trying to write a piece of code to perform some image manipulation - specifically, to mathematically subtract one image from another... I can't see a ready made function for this in Gambas. So you would either have to cycle through the 2 dimensional array for each of the 2 images, and subtra...

Re: Quote character in mysql search string
OK, so it looks like your quoting problem is with SQL not Gambas (i.e. you need to quote to suit SQL rules).

Re: Quote character in mysql search string
I hate this quoting problem. It comes up from time to time and I never seem to remember what I did last time. In an example where I was running a Gimp script I did this:- strExt = Quote("*.[jJ][pP][gG]") strCommand = "cd " & DirView1.Current & " && gimp -i -b...

Re: Raspberry Pi camera module
...how to detect there is text printed at the box or not... I think any solution will be relatively complicated, and if this was a real industrial conveyor system, you would need a proper rugged transducer/reader, rather than a RaspiCam. But as an academic exercise, you would need to use some form ...

Re: Send command "string" over tcp/ip
Hey Jornmo, any idea why the "If" in the first instance of "End If" in my post above is coloured pink not blue?
I'm sure it has to be something obvious.

Re: Send command "string" over tcp/ip
I created a form with one button, my purpose is to send string over tcp/ip... You probably need to start again by creating a Gambas project including the gb.Net component. Then you can add a Button and a Socket to the Form. Rename the Socket: ClientSocket Use properties to set IP address and Port:-...

Re: Advanced HMI conversion to gambas
