TBDimensionConverter converts device independant points to pixels, based on two DPI values.
Dimensions in Turbo Badger are normally in pixels (if not specified differently) and conversion normally take place when loading skin.
| int tb::TBDimensionConverter::DpToPx | ( | int | dp | ) | const |
Convert device independant point to pixel.
|
inline |
Get the destination DPI.
| void tb::TBDimensionConverter::GetDstDPIFilename | ( | const char * | filename, |
| TBTempBuffer * | tempbuf | ||
| ) | const |
Get the file name with destination DPI suffix (F.ex "foo.png" becomes "foo@192.png").
The temp buffer will contain the resulting file name.
|
inline |
Get the file name suffix that should be used to load bitmaps in the destination DPI.
Examples: "@96", "@196"
| int tb::TBDimensionConverter::GetPxFromString | ( | const TBStr & | str, |
| int | def_value | ||
| ) | const |
Get a pixel value from string in any of the following formats: str may be nullptr.
def_value is returned on fail.
Device independent point: "1", "1dp" Pixel value: "1px"
| int tb::TBDimensionConverter::GetPxFromValue | ( | TBValue * | value, |
| int | def_value | ||
| ) | const |
Get a pixel value from TBValue.
value may be nullptr. def_value is returned on fail.
Number formats are treated as dp. String format is treated like for GetPxFromString.
|
inline |
Get the source DPI.
| int tb::TBDimensionConverter::MmToPx | ( | int | mm | ) | const |
Convert millimeter to pixel.
|
inline |
Return true if the source and destinatin DPI are different.
| void tb::TBDimensionConverter::SetDPI | ( | int | src_dpi, |
| int | dst_dpi | ||
| ) |
Set the source and destination DPI that will affect the conversion.
