Hello! I´m having a problem debugging the following script:
------------------------------------
import appuifw, graphics, e32, key_codes
mask_img = graphics.Image.new(size=(50,50), mode='1')
mask_img.load(u"E:\\Python\\mask_img.png")
src_img = graphics.Image.open(u"E:\\Python\\orig_img.png")
-------------------------------------

I have in that directory a file called orig_img.png .
The error is:

File "c:\resource\graphics.py", line 104, in load

self._image.load(self._filename, self_callback)
SymbianError:[Errno -1]

Bye!

Hi,
Is this a complete code or a part of the code?

[BAM8]

The script follows this way:

canvas = appuifw.Canvas()
appuifw.app.body = canvas
canvas.blit(src_img, target=(0,0), source=(0,0), mask = mask_img)

but I became an error when loading the file "mask_img.png".

Bye!

Hi BAM8
Try this code it is working with my phone

import graphics
import e32
import appuifw
can=appuifw.Canvas()
appuifw.app.body=can
m=graphics.Image.new(size=(585,834), mode='1')
i=graphics.Image.open("e:\\1.jpg")
m.load("e:\\2.jpg")

can.blit(i,target=(0,0),source=(0,0),mask=m)
e32.ao_sleep(5)

i think in your case while you create a new image for mask its size should be same as the size of the image that you are gng to load.

Hi,
Have you check the size of the file mask_img.?
It should be (50,50) because you create a new image with that size.

Hi BAM8,

Well, I have answered this same question some days ago. Take a look at this thread. And next time, please use the search function of the DiBo to see if your question has been answered before creating a new thread. Then, we won't have repeated threads and the forum will be cleaner

EDIT: I also made an article on the Wiki for getting things easier.


BR,

Rafael.

Hello! Thank you, I had a problem with the size of the file but now... I have another problem, if I don´t create a file called mask_img.png and paste it in the directory , it returns an error and if I create it the image doesn´t change, that´s to say, in the mask_img.png I don´t have a copy of src_img. Bye!

Hi,
i cant get your problem. Can you please explain it in detail?

[BAM8]

Hello! Yes,of course, I can explain it in detail: The problem now is that if I don´t create a file called "mask_img.png" I get an error, but if I create it, I don´t get an error but I don´t get the result I want, because with the script I should get an image in black and white, a mask.
My script is:

-------------------------------------------------
import graphics, e32, appuifw

mask_img = graphics.Image.new(size=(675,900), mode='1')
mask_img.load(u"E:\\Python\\mask_img.png")
src_img = graphics.Image.open(u"E:\\Python\\orig_img.png")
canvas = appuifw.Canvas()
appuifw.app.body = canvas
canvas.blit(src_img, target=(0,0), source=(0,0), mask = mask_img)

Hi BAM8,

Are you sure your mask is the same size of your main image? I would try a smaller image for testing. Try something like a B&W icon first - size 40,40; for example



BR,

Rafael.

Hi,
I agree with rafael , you should try it with some small image. Second thing make sure that your mask img and source img should be of the same size. You can try to resize your image so that full img is display on the canvas. Otherwise i dont think there is any problem in your script now.
