Decompress JPEG Baseline (Process 1)

[Oscar Peña-Nogales]

Describe the bug
The decompress() method seems not to be working with this data with image-00000.dcm included in the attached zip file. This is the original file that that I want to transform to Explicit VR Little Endian. If I use the pydicom.decompressed method the resulting image looks like:

while if I use dcmdjpeg the image is like:

It seems like the decompression was not done correctly.

The following works fine for me with GDCM, which should be the first handler you're using:

from pydicom import dcmread
from pydicom.pixel_data_handlers import convert_color_space

import matplotlib.pyplot as plt

ds = dcmread("image-00000.dcm")
ds.decompress()
rgb = convert_color_space(ds.pixel_array, "YBR_FULL", "RGB")

plot = plt.imshow(rgb)
plt.show()
