These JSFL scripts will automatically convert PNGs into SWFs using flash professional.
Why using SWFs instead of PNGs into an hyperspin theme? Flash supports a "smooth" feature, when "smooth" flag is used a SWF will look much better than a PNG when hyperspin runs at a resolution higher than 1024*768. If you plan to use 1024*768 on hyperspin, instead, it is better to NOT use "smooth" as the artwork will be blurred a bit.
This is mostly a workaround for those who wants to design future-proof themes at 1080p. Create your artworks layer in photoshop (or gimp or whatever) at 1080p, save background and artworks as .png in a folder. Double click the script and point to that folder in flash (a dialog will appear). The script will convert EVERY PNG in the chosen folder to SWF. Basically you create png assets for a 1080p theme and the script will convert them to swf usable in the current version of hyperspin.
SCRIPTs EXPLANATION
1080p to 1024*768 scripts
PNG_to_SWF_dark13_1080p_scale_Artwork: Use this script to convert artworks. The swf canvas will have 1 more pixel on Y and 1 more pixels on X and no-pixels will be lost when the scale will result in something like 333,45px
PNG_to_SWF_dark13_1080p_scale_BK: Use this script to convert 1920*1080 background, embed pngs will be 1024*768, canvas will be 1024*768
PNG_to_SWF_Zero_Dreams_1920x1080_to_1024x768: Use this script to convert 1920*1080 background, embed pngs will be 1024*768, canvas will be 1024*768 (maybe more precise as it's not a % based scaling but a resolution scaling)
4:3 to 16:9 Script
PNG_to_SWF_dark13_4-3_to 16-9_Conversion: Use this script to convert 4:3 assets to 16:9 assets. Useful when converting pre-made artworks for 16:9 themes
PNG to SWF scripts
PNG_to_SWF_dark13_NO_SCALE_SMOOTH: Use this script to convert PNGs to SWFs. If you prefer to correct aspect ratio in photoshop use this script.
PNG_to_SWF_dark13_NO_SCALE_NO_SMOOTH: It's basically unuseful. Using this script you can see the difference in a SWF when smooth flag is not used.
PNG_to_SWF_Wheel_Only_Scripts
PNG_to_SWF_dark13_4-3_to 16-9_WHEEL_Conversion
Use ONLY to convert a .png wheelset to .swf wheelset, 4:3 to 16:9 ratio
PNG_to_SWF_dark13_4-3_WHEEL_Conversion
Use ONLY to convert a .png wheelset to .swf wheelset, 1:1 ratio
--------------------
All those scripts are based on the script you can find here https://www.yofla.com/flash/png2swf/
If you want to check or modify the script just open it with text editor. Jsfl is basically a simple .txt with a jsfl extension.
