.SH NAME
ktx_info \- ktx info 
.PP
Print information about a KTX2 file\&.
.SH "SYNOPSIS"
.PP
ktx info [option\&.\&.\&.] \fIinput-file\fP 
.SH "DESCRIPTION"
.PP
\fBktx\fP \fBinfo\fP prints information about the KTX v1 or v2 file specified as the \fIinput-file\fP argument\&. If the \fIinput-file\fP is '-' the file will be read from the stdin\&. The command implicitly calls \fBvalidate\fP for KTX v2 files and prints any found errors and warnings to stdout\&. If the specified input file is invalid the information is displayed based on best effort and may be incomplete\&.

.PP
The JSON output formats conform to the https://schema.khronos.org/ktx/info_v0.json schema even if the input file is invalid and certain information cannot be parsed or displayed\&. Additionally, for JSON outputs the KTX file identifier is printed using "\\u001A" instead of "\\x1A" as an unescaped "\\x1A" sequence inside a JSON string breaks nearly every JSON tool\&. Note that this does not change the value of the string only its representation\&. JSON output is only supported for KTX v2 files\&. If requested for a KTX v1 file, an error is generated\&.

.PP
\fBNote\fP
.RS 4
\fBktx\fP \fBinfo\fP prints using UTF-8 encoding\&. If your console is not set for UTF-8 you will see incorrect characters in output of the file identifier on each side of the "KTX nn"\&.
