Review Comment:
The mime types in this section appear to be kept in lexicographic order by
type. `application/vnd.android.axml` should sort before
`application/vnd.android.package-archive`, but it is currently placed after it,
which makes future diffs/merges harder to follow.
> tika-4.0.0-alpha1 - PDF and Tesseract Parser Comments
> -----------------------------------------------------
>
> Key: TIKA-4747
> URL: https://issues.apache.org/jira/browse/TIKA-4747
> Project: Tika
> Issue Type: Bug
> Affects Versions: 4.0.0
> Environment: Windows 11
> Reporter: Adrian Bird
> Priority: Major
>
> I've tried the PDF and Tesseract parsers, independently and together and here
> are some comments.
> 1. pdf-parser Full Configuration example
> The [Full Configuration
> Example|https://tika.apache.org/docs/4.0.0-SNAPSHOT/configuration/parsers/pdf-parser.html#_full_configuration]
> has an unknown property "maxPages".
> {code:java}
> Caused by: java.lang.RuntimeException: Failed to parse PDFParserConfig
> configuration: Unrecognized field "maxPages" (class
> org.apache.tika.parser.pdf.PDFParserConfig), not marked as ignorable (39
> known properties: "ocrStrategyAuto", "imageGraphicsEngineFactory",
> "detectAngles", "ocrMaxPagesToOcr", "ignoreContentStreamSpaceGlyphs",
> "accessCheckMode", "extractBookmarksText", "spacingTolerance",
> "extractUniqueInlineImagesOnly", "suppressDuplicateOverlappingText",
> "extractInlineImages", "enableAutoSpace", "imageGraphicsEngineFactoryClass",

> org.apache.tika.parser.pdf.PDFParserConfig["maxPages"])
> {code}
> 2. Refers to 1 above
> In the list of 39 known properties the following do not appear in the full
> configuration example:
> {noformat}
> "imageGraphicsEngineFactory",
> "imageGraphicsEngineFactoryClass",
> "ocrMaxImagePixels",
> "ocrMaxPagesToOcr",
> {noformat}
> 3. Refers to 1 above
> Is there a description of the properties somewhere?
> 4. Tesseract OCR Full Configuration example
> The [Full Configuration
> example|https://tika.apache.org/docs/4.0.0-SNAPSHOT/configuration/parsers/tesseract-ocr-parser.html#_full_configuration]
> didn't work for me.
> I saw the following message:
> {noformat}
> DEBUG [main] 10:48:58,549
> org.apache.tika.config.loader.AbstractSpiComponentLoader Skipping SPI parsers
> - 'default-parser' not in config
> {noformat}
> and decided to add the following:
> {code:java}
> {
> "default-parser": {}
> }
> {code}
> That fixed the problem.
> The pdf-parser worked without this 'default-parser' entry.
> 5. Refers to 4 above
> Is there a description of the properties somewhere?
> Also, is there some documentation to say ImageMagick is an optional component.
> 6. Disabling Tesseract
> A message is output that refers to the old XML way of disabling Tesseract:
> {noformat}
> INFO [main] 09:32:13,811 org.apache.tika.parser.ocr.TesseractOCRParser
> Tesseract is installed and is being invoked. This can add greatly to
> processing time. If you do not want tesseract to be applied to your files
> see:

> {noformat}
> 7. ImageMagick and Tesseract locations in Windows
> If I use a Windows path for the ImageMagick or Tesseract locations I get an
> exception (using / on Windows works ok):
> {noformat}
> "imageMagickPath": "C:\ImageMagick",
> "tessdataPath": "C:\Tesseract-OCR\tessdata",
> "tesseractPath": "C:\Tesseract-OCR",
> {noformat}
> gives the following for an invalid Tesseract location:
> {noformat}
> Exception in thread "main" java.io.IOException:
> com.fasterxml.jackson.core.JsonParseException: Unrecognized character escape
> 'T' (code 84)

> 8. ImageMagick Failures
> When Tika runs ImageMagick it always returned an error code of 1.
> ImageMagick on path and no "imageMagickPath" key set gave these messages:
> {noformat}
> Use "magick" instead of the deprecated command "magick convert".

> -filter triangle -resize 200% image.jpg image.png

> error/constitute.c/ReadImage/746.
> {noformat}
> If I change it by removing the 'convert' and putting the source image at the
> start:
> {noformat}
> %IMAGEMAGICK_HOME%\magick image.jpg -density 300 -depth 4 -colorspace gray
> -filter triangle -resize 200% image.png
> {noformat}
> it runs successfully.
