TTransform
Razred TTransform je namenjen transformaciji koordinat.
Tipično se uporablja na dva načina.
Uporabnik lahko sam nastavi parametre v prikazanem oknu:
// odpre masko z nastavitvami in nato izvede transformacijo
If Transform.Edit Then
Transform.Execute
EndIfali pa izvede transformacijo s fiksnimi nastavitvami:
// naredi nekaj
Transform.InputLayer = [ime plasti]
Transform.OutputLayer = L2
Transform.TransformType = 1
Transform.TransformLayer = L
Transform.TransformCoorType = 2
If InputPolygon ("Vnesi območje transformacije", PA) Then
Transform.Area = PA
Destroy (PA)
Else
Transform.Area = Nil
EndIf
Transform.ExecuteEdit
Metoda Edit odpre masko za roćno določanje nastavitev transformacije.
| Method TTransform.Edit As Boolean | ||
| Result | Optional Boolean | Vrne true/false glede na to, ali je uporabnik zapustil masko s Potrdi oz. Opusti. |
Execute
Metoda Execute izvede transformacijo podatkov iz vhodne v izhodno podatkovno plast.
| Method TTransform.Execute As Boolean | ||
| Result | Optional Boolean | Metoda vrne true/false glede na to, ali se je transformacija uspešno izvedla. |
InputLayer
Lastnost InputLayer nastavimo vhodno podatkovno plast transformacije. Kadar se nastavi InputRecordList, je ni potrebno nastavljati, ker se upošteva kar podatkovna plast iz liste zapisov.
| Property TTransform.InputLayer As TLayer | ||
| Result | TLayer | . |
InputRecordList
Lastnost InputRecordList nastavimo vhodno listo zapisov transformacije. Če se ne nastavi oz. je nastavljena na nil, se privzame lista vseh zapisov. Če se nastavi, ni potrebno dodatno nastavljati InputLayer, saj se plast prevzame iz liste zapisov.
| Property TTransform.InputRecordList As TRecordList | ||
| Result | TRecordList | . |
TransformType
PropertyTransformType . 0 - Linearna transformacija 1 - Po kvadratu oddaljenosti 2 - Kvadrat oddaljenosti (Veliko transformacijskih točk) 3 - Med koordinatnimi sistemi
| Property TTransform.TransformType As Long | ||
| Result | Long | . |
TransformCoorType
PropertyTransformCoorType . 0 - Centroid + Nova lokacija 1 - Centroid + Stara lokacija 2 - Linija (stare proti novi lokaciji)
| Property TTransform.TransformCoorType As Long | ||
| Result | Long | . |
OutputLayer
Lastnost OutputLayer nastavlja izhodno plast transformacije. Če se ne nastavi, se avtomatsko naredi nova plast in je po Execute ukazu shranjena referenca na novo plast. Če pa je nastavljena, se podatki in struktura obstoječe plasti briše in ponovno nastavi iz vhodne plasti za transformacijo.
