Good afternoon everybody.
I want to process an image with tesseract. I managed to read a simple text. Now, I want to read the text that is put inside the cells of a table. I think that the best way to do it is to remove the straight lines of the table, but I've no idea to make it. Can you help me?
Thank you in advance.

I tryied to create a Pizza that is able to be split in pieces...
The circle itself aint been any Problem, as its a rounded Container, but to cut it by lets say "1-8 pieces", and make it possible to split it individually, and get the circle equally fair splitted visually. If someone could help me with this, i would really appreciate it as im pretty new to Flutter/Dart, and couldnt find any workaround for this problem. thanks.
Take a look at this package. It adds pie charts to flutter. This will probably cover your use case.
I have a stitched png file that is 100 frames of a gauge going from 0 to 100. Each frame is 80x80.
I am loading the image into a pixbuf using gdk_pixbuf_new_from_file and attempting
to use gdk_cairo_set_source_pixbuf to navigate to the frame that I want to display.
I am getting the first frame when gdk_cairo_set_source_pixbuf(cr,pixbuf,0,0), however if I try to advance (for example at the gauge at 50%) and use gdk_cairo_set_source_pixbuf(cr,pixbuf,0,4000) ...I don't get anything. I am getting no images other than when I am using 0,0.
I am new to this so any advice on what I may be doing wrong, or suggestions of alternate ways to do what I am looking to accomplish are appreciated. I have been searching for existing examples of someone using a subset of an image, but haven't been able to find any.
thank you.
Im pretty new to mkmapview so I'll hope my question will be clear enough.
Let's say I have a code where im saving the userLocation in an array (MKuserLocation type). im saving this for every step the user take and than I want to display this.
How do I do that? how can I use this userlocation with the coordinates that I save and display the path?
* im adding this after the comment I was told to use MKmapoverlay. does someone can give me an example how to use this with coordinates? or have some guide (I really tried something clear enough on google but didn't)
Thanks
yes, you can make a path from thoses point. You must be careful to to have your array of point in the right order otherwise you will draw lines between point in every direction. you can draw a line with an mkoverlay
I have faced same issue few days ago and I found the sample application on GitHub.you can download the project from here.
I hope it will be helpful !!

I am drawing strings in a rectangular frame. The string is drawing perfectly. Now I need to write test cases using sentesting kit. I have no ideas from where I should start. For help I have also seen the iPhone sample calculator application
But still out of sorts.
Any body having ideas please help.
Thanks,

GUI drawing code is often hard to test. In your case it depends how you draw your string. If you draw it into a custom view by using the -(void)drawRect: method and therein just drawing your NSString (I suppose), then I do not think your can test that this drawing happend properly.
If you use a separate view like a UITextLabel you could test for its existance by using STAssertNotNil. You could also check the proper positioning by checking the view's bounds.
If you need more help, please be a bit more specific and adding clean code would help.
