Criar matriz de byte atraves de uma String

Delphi

27/05/2008

Galera, seguinte tenho uma imagem que é guardada em uma matriz do tipo byte, ela é assim:

const byte RPrint [] = {
0x01, 0x01, 0x01, 0x31, 0x00, 0x30, 0x38, 0x30, 0x02, 0x20, 0x89, 0xE0, 0xE3, 0xF0, 0xF9, 0xFD,
0xFD, 0xFE, 0xFE, 0xFF, 0xFE, 0xFE, 0xFE, 0xFE, 0xFE, 0xFE, 0xFF, 0xFE, 0xFE, 0xFE, 0xFE, 0xFE,

};

só que eu preciso construir esta matriz dinamicamente, este conteudo está nums string tipo

StringImagem = ´ 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x7F, 0x3F, 0x3F, 0xBF, 0x3F, 0x7F, 0x3F, 0x3F´ ....

como faria para montar cada codigo hexa dentro de uma posição de minha matriz
tipo eu tenho ela criada zerada byte RPrint [];
tem alguma maneira de fazer isso?
pq eu uso a variavel RPrint para imprimir a imagem....

Obrigado desde jah!

Usando C++ Builder:

O código abaixo faz o que você quer. Só que a função HexToInt() não existe. Mas como você é um cara esperto, vai dar uma olhada na net e descobrir como converte Hexa para Inteiro.
AnsiString StringImagem = "0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x7F, 0x3F, 0x3F, 0xBF, 0x3F, 0x7F, 0x3F, 0x3F";
TStringList *lista = new TStringList();
lista->CommaText = StringImagem;

byte *vetor = new byte[lista->Count];

for (int x=0; x<lista->Count; x++) {
    AnsiString valorHexa = lista->Strings[x].Trim().SubString(3, 2);
    vetor[x] = HexToInt(valorHexa);
}

delete[] vetor;
delete lista;

Tem que ser em C,
um colega passou uma função, soh que o problema ta quando passo a variavel char para a variavel byte.. quando mando imprimir não sai o esperado, ou seja, os 0x00 não estão sendo inseridos como hexa....

Quando você tenta imprimir uma sequência de caracteres que tem 0x00 no meio da sequência, ele pára de imprimir no caracter zerado.
Se quizer poste o código aqui que eu tendo dar uma olhada.
