It's fantastic : Many responses to my problems.

The Jimi home page is http://java.sun.com/products/jimi/ You can download the whole package there, including Source, JavaDoc and, most valuable, additional docs describing supported file and image formats. For TIFF, the following compression schemes are supported - Uncompressed images - CCITT compressed Bi-level images with CCITT RLE, CCITT Group 3 1D Fax, CCITT Group 3 2D Fax, CCITT Group 4 Fax - CCITT Class F Fax - Packbits compressed images (a simple RLE type compression) - LZW Compressed images JPEG compression is not supported. The TIFF spec is available from http://partners.adobe.com/asn/developer/PDFS/TN/TIFF6.pdf Compression schemes are Packbits: run length encoding (Sec. 9) CCITT G3 Fax (Sec. 10) CCITT Bilevel (Sec. 11) LZW (Sec. 13) JPEG (Sec. 22) CCITT Class F compression is apparently defined in a RFC, for example available here: http://www.zvon.org/tmRFC/RFC2306/Output/chapter3.html It is also mentioned that Jimi does only understand black and white (bilevel), grayscale (palette) and RGB (palette and direct color). CMYK, Cie L*a*b* and YCbCr color models are not implemented. It is not mentioned whether compression predictors are supported, I supposed not (does anybody use them?). It is also not explicitely noted how Jimi deals with alpha channels. If uncompressed TIFF comes out black, probably the color model or palette size is inconvenient for Jimi. J.Pietschmann

Do you know of a JAI implementation, preferably OSS and/or freely available, which supports all common subformats of TIFF, PNG, BMP and perhaps a few more? A quick sweep through sourceforge revealed only a TIFF implementation. The Sun JAI implementation offers all the formats, but installation requires more than just dropping a jar into the classpath, and it contains platform specific binaries (good for speed but screws Mac users and others).

What kind of TIFF does FOP support
Hello, I have to create document with TIFF illustrations. It seems that some TIFF formats are supported and thers are not ( a black area replace the illustration). Can some one tells me what kind of TIFF FOP supports ? thanks
RE: What kind of TIFF does FOP support
most renderers may support uncompressed tiffs... pls correct me if i am wrong. -Original Message- From: Rodolphe VAGNER [mailto:[EMAIL PROTECTED] Sent: Monday, June 24, 2002 3:47 PM To: [EMAIL PROTECTED] Subject: What kind of TIFF does FOP support Hello, I have to create document with TIFF illustrations.

RE: What kind of TIFF does FOP support
I would like to recall this msg posted earlier by J. Pietschmann Jimi.jar doesn't understand all possible compressions allowed in TIFF. Use uncompressed or RLE compressed TIFFs.
