[Pharo-project] PNGReadWriter2Plugin
Hello Is somebody have built windows PNGReadWriter2Plugin dll? Can you share it? Best regards, Denis
http://www.squeaksource.com/PNGReadWriter2.html I found old email about this (2006 year). And author wrote that he build windows version but without links. 2010/12/22 Igor Stasenko <siguctua@gmail.com>

Why do we need a plugin for this? So far, I am quite happy with the exportAsPNG found in Morph. Cheers, Alexandre On 22 Dec 2010, at 17:10, Igor Stasenko wrote:

I just search more faster way to read png files. I read discussion about bmp plugin. And primitive supported reading is 10 times faster then smalltalk implementation. And I start to search png analogous. And I found PNGReadWriter2 plugin. 2010/12/22 Alexandre Bergel <alexandre@bergel.eu>

ok, it is for speed. so why don't we use a FFI (FFI, Alien, NB or another) to directly call external lib? #Luc 2010/12/22 Denis Kudriashov <dionisiydk@gmail.com>

Luc the primitive is just about one loop for reading and one loop for writing. So this is not calling an external library. Igor could not resist to show me the NB implementation he did about that primitive a while ago. I guess that this is terrible for igor to get a mac because he will not stop working before the vm builds from hudson (he worked last night until 3 in the morning :)). native boost works on mac and a lot more :) Now seriously for native boost this may be a problem to rely on platform assembler generation to get speed when C is a portable assembler. So probably
Ah ok, it makes sense Alexandre On 22 Dec 2010, at 17:25, Denis Kudriashov wrote:

I ask myself the same question: why do we need plugins to read/write images (PNG, BMP, ..)? I would understand it for JPG which requires some heavy computation. any hint? #Luc 2010/12/22 Alexandre Bergel <alexandre@bergel.eu>

the true fun part of the discussion is that igor wanted to get rid of the plugin and andreas said that BMP is really used but apparently the plugin has not been invoked for years in Squeak and Pharo. So may be it is not that used after all :) Life have beauty when you know how to look at it :)
