Python / PySFML hanging on initiation. (pysfml-cython)

« on: May 02, 2012, 04:41:33 am »

Hey all.

Was hoping you could help on this issue. Recently, PySFML has been creating an infinite hang when imported. Some details:

>>> import PySFML
>>> dir(PySFML)
['__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']
>>> for attr in dir(PySFML):
        print attr, getattr(PySFML, attr)

       
__all__ ['sf']

I've just reinstalled a clean copy of python, and copied across a clean build of PySFML which i know has worked previously.

If you need any more info, just ask

Any help would be greatly appreciated!
I would be moving across to PySFML2-cython, however i'm on a bit of a tight schedule, and don't have the time to recode large parts of my helper libs.

Many thanks in advance, AClockWorkLemon

Graphics / Image load error reporting incorrect size

« on: February 13, 2012, 08:14:58 am »

Heya!

In an application i'm working on, on some hardware it is throwing an error when trying to load high resolution errors

Code: [Select]

Failed to create image, its internal size is too high (4096x4096)

I've already googled around, and know that this is to do with the graphics card is not powerful enough to load such a large image, however none of the images themselves are 4096x4096. The particular image i was testing on is one of the largest, and is ~3000x~2000.

I realise that this most likely has no effect on the actual error, however i was wondering if anyone would be able to explain the incorrect reporting of the image size.

If it is of any help, i am running PySFML 1.6, compiled from the latest Trunk revision in python 32 bit.

Graphics / 'Blobby' fonts

« on: December 08, 2011, 01:13:43 pm »

Heya, was wondering if you guys could help.

Project i'm working on has need of fonts, however most text rendered seems to be coming out a little.. 'blobby'. Not sure really how to put it, so here's a picture:



The font is Gotham-book
This is the "Text" class i'm using to handle fonts etc:

Code: [Select]


class Drawable(object):
def render(self, win, offset=Point(), camera=Point()):
self.SetPosition(self.x+offset.x-camera.x, self.y+offset.y-camera.y)
win.Draw(self)

class Text(sf.String, Drawable):
def __init__(self, text, font, size):
self.font = GetFont(font, size)
sf.String.__init__(self, text, self.font, size)
self.x = 0
self.y = 0

fontCache = {}
def GetFont(loc, size):
try:
fnt = fontCache[loc]
old_size = fnt.GetCharacterSize()
if size < old_size:
return fnt
except KeyError: pass
Font = sf.Font()
if not Font.LoadFromFile(loc, size):
return None
fontCache[loc] = Font
return Font


If you need more, please feel free to ask ^_^

thanks in advance

Python / [Solved] How to load sf.Images in a separate Thread/process?

« on: October 14, 2011, 08:05:00 am »

Heya!

I was hoping someone could outline how to load images in a separate thread/process with PySFML. I gave Thread a go, and found that it was blocking the PySFML thread. After searching around for a bit, i found Process, which didn't block the main thread at all. However, i have been unable to send the data of the loaded images to any other threads. (Python interpreter complains about being unable to pickle the Image)

If anyone could help sort out this issue, it'd be greatly appreciated!

Python / PySFML 1.6 Fixed build (windows)

« on: October 06, 2011, 02:40:35 am »

Heya all!
For all of you who have been having trouble with PySFML1.6 (both the crash on exit error and the missing SetSmooth functions), this is for you!

This build is built from the 1.6 SVN Trunk, using MinGW32. To use, just replace all the files in your site-packages/PySFML folder with the files in the package (it should be possible to just replace the .pyd, but i cant promise anything)

Python / [ignore] pysfml2-cython build request / weird errors

« on: October 05, 2011, 04:16:36 pm »

Hiya people!

I was just in the hopes that someone could build/provide their binaries for PySFML2, Python2.7.

Please do not take this as me being lazy! I would compile myself, however i both lack  something to compile on (my main computer is getting repairs, this computer i don't wish to install compilers on), and confidence.

Thanks in advance!

Ninja edit
Or, if possible, a version of PySFML 1.6 without that stupid Image.SetSmooth issue. that'd be eppppiiccc

again, thanks in advance

EDIT
PLEASE IGNORE THIS THREAD! I've got it all sorted now

Graphics / [solved] Issue with blurring

« on: October 02, 2011, 06:06:50 am »

Heya, first post here so sorry if i make a few mistakes.
I'm pretty new to SFML, but things seem to me (mostly) working out as-so-far. That said, i've run into an issue with drawing sprites onto the screen. The sprite is being drawn in the correct position, however it would seem to be slightly blurred. I'm guessing that this has something to do with the fact sprites are positioned with floats, but i'm not sure.
Here's a comparison between the Source image and the Output (I've scaled them up a bit so it's easy to see)

SOURCE

OUTPUT


If it's of any help, this is the snippet of code which renders it. If you need more code, feel free to ask :3

Code: [Select]


def Render(self, App, pos=(0, 0)):
self.SetPosition(self.x+pos[0], self.y+pos[1])
App.Draw(self)
