(I hope my prose is not too confusing). luigi.scarso wrote: > Hi, I'm working on a project that require filling forms. > Every field has (x,y,width,height) dimension and > ui=(barcode,texEdit) type (textEdit has some attributes too) I would have used two separate macros then, one for barcodes and one for textEdit. More macros that each do less is generally faster than fewer macros that do more. If you have 200 fields, don't be scared to define 200 named macros for them > > \def\Field[#1]{% > \bgroup > \getparameters[!!][#1]%% collect key/val You could use \rawgetparameters in this kind of input. It is a lot faster and you have complete control over spaces in the input, so there is no need to use the slower \getparameters. > % > % > %%%% textEdit > \doifsamestring{\!!ui}{textEdit}{% text field \doifsamestring is quite slow. A faster solution: most arguments can only be one or two different things, right? Then you can predefine a macro for the possible cases, say \dotextEdit and \dobarcode, and replace most of the body of the \Field command with \getvalue{do\!!ui} I would suggest you try to do this pre-defining trick for all things you can possibly get away with. String comparisons in macro code are very expensive compared to the C lookup times for macro names. Another example: \doifsamestring{\!!para@hAlign}{left}{% \hbox to \!!w {\getvalue\s!dummy \vphantom{K} \getvalue\!!name \hss}% }% is a lot slower than: \def\parahAlignleft{% in the preamble \hbox to \!!w {\getvalue\s!dummy \vphantom{K} \getvalue\!!name \hss}% } followed by \getvalue{parahAlign\!!para@hAlign} % in actual code What is that \getvalue\s!dummy doing there, btw? I don't see what purpose it serves. You can also gain a considerable bit of speed by using an explicit \hrule with the correct size, instead of \vphantom{K}. Or just put the dimensions in a global \hbox beforehand: % in the preamble \newbox\Kbox \setbox\Kbox=\hbox{\vphantom{K}} \def\parahAlignleft{% \hbox to \!!w {\getvalue\s!dummy \copy\Kbox \getvalue\!!name \hss}% } Oh, and grouping is also slow. Why would you bother restoring stuff if you will overwrite the values before the next use ? There is no need for \bgroup ...\egroup around the pages if every page defines every field anyway. I'm quite confident that a near-optimal solution will look like this: ... lots and lots of macro defs, \starttext %% Some 200 \getvalue calls \getvalue{codicearticolo_len6}{957803} \getvalue{barcode_codice___matricola}{*9F9578030052201312*} \page Final trick: when in doubt, run TeX with \tracingall \tracingonline=0 in the preable, on an input file of just a few pages. The general rule of thumb is: the smaller log file, the faster the 'real' run will be. I hope this helps, Taco ^ permalink raw reply [flat|nested] 7+ messages in thread

It's \blackrule that triggers the change, not the \definecolor, but you nevertheless gave me an idea! I will make a 0 times 0 box on the first page which eventually solves the problem then, but this should be solved generally. > Under linux with acro7 I can't see differences. After turning "separation preview" on, the colors appear to be "equal" again (for the time when the little pup-up window is there, then the changes appear again). I guess that the first title is typeset with "rgb" blue and the second one with "cmyk" blue. With proper profile settings, the colors appear to be the same (and should look the same), but I'm affraid that they aren't. However, I don't know how to check this. It's quite possible that under windows some weird profile for converting rgb <-> cmyk is chosen. Thank you, Mojca ^ permalink raw reply [flat|nested] 7+ messages in thread
