Android Question Crop bitmap

[Shivito1]

i need to crop screen shot bitmaps continuously. However all the threads I've found use saved images when cropping.

Which version of b4a have you? In 7.30 (maybe 7.0+, don't remember) there is Bitmap.Crop method

I have 6.80

You need so to use a Canvas

Try this code and edit the rect to crop image at coordinates that you want

I'll give it a try but it looks like it requires me to load a file saved on my device.

Are you able to get ScreenShot? You can use it as bitmap. You don't need a file saved, you can have a bitmap in memory, or download it, or other options.. You for sure need a bitmap by the way

maybe this will work. wonder if I can make it a rectangle instead of a circle

Thanks!!! Hopefully I can get it to work. I have to improve my searching.

Man I can't catch a break with this. I tried a couple times to get it to store it as a bitmap instead of drawing it. However the method I'm using keeps giving me a void error.
How can I get it to store as a bitmap after applying the canvas?

Write stream... (Or stream out, can't remember)

I thought that was to save the file to the device. I'll doublecheck

 

[Cableguy]

I thought that was what you wanted

No because then I would have to read it again so that I can pass it through OCR

 

[Cableguy]

canvas has a method to convert to bitmap, if I recall correctly... But it's been a while since I've used it

 

[Shivito1]

the only one that sounds correct is
canvas.bitmap
however it does not convert it to a bitmap that I can use. All it allows me to do is WriteToStream.... This will create a file on the device and that is not what I need.

Canvas.Bitmap returns a regular bitmap object.

 

[Shivito1]

So how can I get my canvas creations back to bitmap? Preferably without saving it to the device first

 

[DonManfred]

canvas creations back to bitmap?

dim newbm as bitmap = canvas.Bitmap

?
