Zoom in, s60 image

2 New Member
Hi,

I'm writing in python for s60 (nokia cell.) and working with Canvas and Image,
while i'm moving through the image using:

Expand|Select|Wrap|Line Numbers
  1. canvas.blit(image, source=((sourceLocX, self.sourceLocY),
  2. (sourceLocX+ canvas.size[0],
  3. sourceLocY+self.canvas.size[1])))
i can't seems to zoom in/out, I looked into Image and Canvas documentation and still don't
understand how to do that...
anyone knows ?


Best,

Expand|Select|Wrap|Line Numbers
  1. canvas.blit(image, source=((sourceLocX, self.sourceLocY),
  2. (sourceLocX+ canvas.size[0],
  3. sourceLocY+self.canvas.size[1])))
Simply based on the code you've posted here I'd say:
Expand|Select|Wrap|Line Numbers
  1. canvas.blit(image, source = ( ( self.sourceLocX, self.sourceLocY ), \
  2.     ( self.sourceLocX + self.canvas.size[0], \
  3.       self.sourceLocY + self.canvas.size[1] ) ) )
The thing you want to make sure you keep track of is the self. notation. This allows you to access members of self . So depending on which of the elements (sourceLoc*, canvas, etc.) are members of self, they should always be prepended with self.

What error codes are you getting? Or is simply nothing happening?

Hello: I am trying to design a web page whose graphics content would change according to the "text Zoom" settings of the user. (Basically the goal is to use mathematical symbols that automatically resize in response to zoom events). Is it possible to detect a zoom change event? Stefan

Hi there, I have an image on my ASP.Net page and i created a <p> tag that can be dragged around the screen.. I needed to get it so that when the <p> tag is over the image, whatever is inside, or behind (however you want to call it), only that part gets zoomed in... so i need the box and the image to always be the same original size and only when the box is placed over the image, the part of the image within the box will get zoomed..

Hello, I am putting together a simple picture viewing program to view jpg. bmp pictures. I have the picturebox sizemode set to autosize.

In MS Access image controls there's a property setting for "Size Mode" --> Clip, Zoom or Stretch. I don't see any similar property in an asp image control. When I have an image on a page, it seems to Stretch no matter what. If an image is displayed that has different proportions than the image control itself, the image is distorted. I need a "Zoom" setting (not to zoom in and out). How can this be done? Thanks, Keith

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
