Kim Woelders 8d3539234d x11_grab: Drop now unused 1:1 scaling path in __imlib_GrabDrawableScaledToRGBA() 2023-02-19 22:36:46 +01:00
Kim Woelders 5ea6a407cf imlib_create_scaled_image_from_drawable(): Simplify call path 
On 1:1 scaling call  __imlib_GrabDrawableToRGBA() directly instead of
going through __imlib_GrabDrawableScaledToRGBA().

This fixes 1:1 grabbing of pixmaps.
Non-1:1 pixmaps grabs are still not ok (window grabs are).

remove bad unused function 
__imlib_FileCanRead() suffers from TOCTTOU issues. The file behind the
path it takes as a parameter can change while the function executes, and
also between the function's return and the caller's use of the path.

The function is also unused, so just delete it.

Kim Woelders 5d16eb8bb8 api: Tweak/correct error handling in drawable grabbing functions 
imlib_create_scaled_image_from_drawable() now returns NULL if the
drawable could not be grabbed, just as imlib_create_image_from_drawable()
has always done.

Kim Woelders dafd7eb33d api: Change some parameter names 
- Shorten some names - mostly to avoid some line wrapping
  source_...      -> src_...
  destination_... -> dst_...

- Change some parameter names for consistency/clarity
  Change (x, y, width, height) to (src_x, src_y, src_width, src_height)
  or (dst_x, dst_y, dst_width, dst_height) a couple of places.

Kim Woelders 207cffb207 Avoid some more undefined behaviors with shifts 2023-01-13 10:55:47 +01:00
NRK e76d9bcf9f PNM loader: avoid some undefined behavior 
`ptr` is a `uint8_t` pointer, which will get promoted to an `int` due to
integer promotion. and shifting a signed int by 24 places could cause
signed overflow which is undefined.

> If E1 has a signed type and nonnegative value, and E1 x 2^E2 is
> representable in the result type, then that is the resulting value;
> otherwise, the behavior is undefined.
