Yes. Generally one font file contains one font set with one weight. You would need to supply a custom font set to get a different weight. Any program which allows you to print in a different weight would do the same, to either require you to have a font set in that weight or to guess at it. Guessing can be bad. For instance I create images from FOP with the PNGRenderer. It gets larger images if I increase targetresolution. If I generate a smaller image then try to make it bigger with the Graphics2D transforming method you can see it gets fuzzy. Optional fuzzy logic could be useful, currently not implemented.

You need to supply the fonts with the weights you specify in FO content." I understand Fop doesn't synthesize the weights. I understand that it has two specific built-in weights (700 and 400) that are being used to replace other weights per the following: When I set-up using a Java2DRenderer and specify the following FO content snippets: <fo:table-cell font-size="10pt" font-family="Helvetica"><fo:block line-height="13pt"> <fo:block white-space-collapse="true"> <fo:inline font-weight="900">900 Weight </fo:inline> ... <fo:inline font-weight="800">800 Weight </fo:inline> ... <fo:inline font-weight="700">700 Weight </fo:inline> ... <fo:inline font-weight="600">600 Weight </fo:inline> ... <fo:inline font-weight="500">500 Weight </fo:inline> ... <fo:inline font-weight="400">400 Weight </fo:inline> ... <fo:inline font-weight="300">300 Weight </fo:inline> </fo:block></fo:block></fo:table-cell> ... the logger gives me the following information: WARNING: Font "Helvetica,normal,900" not found. Substituting with "Helvetica,normal,700". WARNING: Font "Helvetica,normal,800" not found. Substituting with "Helvetica,normal,700". WARNING: Font "Helvetica,normal,600" not found. Substituting with "Helvetica,normal,700". WARNING: Font "Helvetica,normal,500" not found. Substituting with "Helvetica,normal,400". WARNING: Font "Helvetica,normal,300" not found. Substituting with "Helvetica,normal,400". So I would need to supply very specific replacement fonts for Helvetica,normal,900 ( and 800-300, not counting 400)? (Same as above when replacing Helvetica with Arial). I DO understand the following: 1- that per the current specs, item 7.9.9 for font-weight has a "TODO <relative> font weights" message. 2 - that per the current build, the font classes generated from Helvetica.xml and HelveticaBold.xml are used for 400 and 700 respectively 3 - that per the fuzzy replacement, 700 is used for 900-600 and 400 is used for 500-100(probably). So my questions still stand 1 - is there a simpler way to use / access / apply a darker 500 or 600 weight Helvetica and if so, what's the best process to handle it given the codebase? 2 - should I instead render a "Helvetica500.xml" and generate the appropriate font class; obviously since that's not yet been done with the existing fop codebase, it is probably a lot more work than needed. 3 - Any other option I should pursue? If there is a process started to handle item 7.9.9, I would be happy to pitch in and help, I am just not certain where to start.

We're using Helvetica and using FOP to take the FO file and generate it as both (1) a PostScript file and (2) a TIFF file. Additionally, we are able to use third-party software to take the PostScript file and convert it directly to a second TIFF file (for comparison reasons). Of course, the fonts on the TIFF from FOP are a little pixilated and the "normal" font could stand to be rendered a bit darker. I am using Helvetica and tried to set the font-weight to 500 or 600, but it gets replaced with weight 400, which is apparently the "normal" Helvetica font registered in the system. Font-weight Bold and values of 800 and 900 use the "bold" Helvetica which is weight 700. Is there an easy way to use / access a darker 500 or 600 weight Helvetica, or possibly render the or am I really sunk here? I've already extended the Java2DRenderer, for my own purposes. The following Graphics2D rendering hints don't seem to do much when included: graphics.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, RenderingHints.VALUE_FRACTIONALMETRICS_ON); graphics.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); graphics.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON); graphics.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); graphics.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE); Suggestions would be very helpful.
