| Description
INT LOAD_PNG (STRING ARCHIVE) It recovers of disk a PNG graph PARAMETERS: STRING archive: Name of archive DESCRIPTION: This function loads a PNG graph from disk. The PNG is a powerful graph format that supports a high compression without loss of data and a lot of other options. Among other things, a PNG graph supports different levels of transparency per pixel. However, Fenix only accepts two levels (a pixel is transparent, or it is not). This function recovers those transparent pixels that have 50% or more of transparency in the PNG, and opaques the rest. LOAD_PNG returns a whole number that identifies the PNG graph. It is then possible to use this value with any function that allows a graph like parameter, indicating the code 0 of library, or assigning the number to the variable Graph. NOTES: It is only possible to visualize graphs of 16 bits if the current graph mode 16 bits. But it is possible to visualize graphs of 8 bits in 16 bit modes. There is an active palette of colours all the time. Use only graphs of 8 bits that use the same colour palette. Fenix will automatically use the colour palette of the first graph returned of the disk and will ignore any other palettes belonging to any graphs loaded after the first one. Even in 16 bit modes a colour palette exists (but in this mode the palette only affects the graphs of 16 bits). |
