将 jpg 转换为 pdf

Question

在我的 Ubuntu 19.10 中尝试转换.jpg为.pdf ：

\n\n

转换给出：

\n\n

joso@joso-Aspire-ES1-433:~$ convert \xe2\x80\x98/home/joso/Desktop/Marticeva etaziranje/IMG_20200104_102541.jpg\xe2\x80\x99 output.pdf\nconvert: no decode delegate for this image format `JPG\xe2\x80\x99 @ error/constitute.c/ReadImage/562.\nconvert: no images defined `output.pdf\xe2\x80\x99 @ error/convert.c/ConvertImageCommand/3273.\n

\n\n

我可以打开jpg文件。在终端中：

\n\n

joso@joso-Aspire-ES1-433:~$ file /home/joso/Desktop/Marticeva\\ etaziranje/IMG_20200104_102541.jpg\n/home/joso/Desktop/Marticeva etaziranje/IMG_20200104_102541.jpg: JPEG image data, Exif standard: [TIFF image data, big-endian, direntries=10, manufacturer=HUAWEI, model=ATU-L21, xresolution=150, yresolution=158, resolutionunit=2, software=ATU-L21-user 8.0.0 HUAWEIATU-L21 156(C432) release-keys, datetime=2020:01:04 10:25:41, GPS-Data], baseline, precision 8, 3120x4160, components 3\njoso@joso-Aspire-ES1-433:~$\n

\n\n

使用命令：

\n\n

joso@joso-Aspire-ES1-433:~$ cp /home/joso/Desktop/Marticeva\\ etaziranje/IMG_20200104_102541.jpg foo.jpg; convert foo.jpg foo.pdf \nconvert: no decode delegate for this image format JPG' @ error/constitute.c/ReadImage/562. \nconvert: no images definedfoo.pdf' @ error/convert.c/ConvertImageCommand/3273. \njoso@joso-Aspire-ES1-433:~$\n

\n\n

还是一样，没有成功。

\n\n

我尝试了另外 2 个文件：

\n\n

joso@joso-Aspire-ES1-433:~$ convert '/home/joso/Pictures/IMG_20191214_120216.jpg'  output.pdf\nconvert: no decode delegate for this image format `JPG' @ error/constitute.c/ReadImage/562.\nconvert: no images defined `output.pdf' @ error/convert.c/ConvertImageCommand/3273.\n\njoso@joso-Aspire-ES1-433:~$ convert '/home/joso/Pictures/John Selman2.jpeg' output.pdf\nconvert: no decode delegate for this image format `JPEG' @ error/constitute.c/ReadImage/562.\nconvert: no images defined `output.pdf' @ error/convert.c/ConvertImageCommand/3273.\n\njoso@joso-Aspire-ES1-433:~$ convert /home/joso/Pictures/IMG_20191214_120216.jpg output.pdf\nconvert: no decode delegate for this image format `JPG' @ error/constitute.c/ReadImage/562.\nconvert: no images defined `output.pdf' @ error/convert.c/ConvertImageCommand/3273.\njoso@joso-Aspire-ES1-433:~$ \n\n\njoso@joso-Aspire-ES1-433:~$ convert -compress jpeg /home/joso/Pictures/IMG_20191214_120216.jpg /home/joso/Pictures/output.pdf convert: no decode delegate for this image format JPG' @ error/constitute.c/ReadImage/562. convert: no images defined/home/joso/Pictures/output.pdf' @ error/convert.c/ConvertImageCommand/3273.\n

\n\n

我可以在图像查看器中打开该文件并file报告它是普通的 jpg：

\n\n

$ file /home/joso/Desktop/Marticeva\\ etaziranje/IMG_20200104_102541.jpg \n/home/joso/Desktop/Marticeva etaziranje/IMG_20200104_102541.jpg: JPEG image data, Exif standard: [TIFF image data, big-endian, direntries=10, manufacturer=HUAWEI, model=ATU-L21, xresolution=150, yresolution=158, resolutionunit=2, software=ATU-L21-user 8.0.0 HUAWEIATU-L21 156(C432) release-keys, datetime=2020:01:04 10:25:41, GPS-Data], baseline, precision 8, 3120x4160, components 3\n

\n\n

我也按照评论中的建议尝试过：

\n\n

$ convert -compress jpeg /home/joso/Pictures/IMG_20191214_120216.jpg    \n/home/joso/Pictures/output.pdf convert: no decode delegate for this image format JPG' @ error/constitute.c/ReadImage/562. convert: no images defined/home/joso/Pictures/output.pdf' @ error/convert.c/ConvertImageCommand/3273.\n

\n\n

我究竟做错了什么？

把事情简单化。使用 libre Office Draw（或 impress）打开 jpg 文件。一旦在菜单“文件”中打开（我想是英文），请使用“导出为 pdf”导出此文件）
